How to Synchronize Multiple Cameras to a Video Switcher

This article covers material from the old Breeze website; and was last updated in 2018.

There are two ways multiple cameras can be fired at the same time using Multi-Camera which are described below. In order to eliminate variable delays due to auto-focus the cameras should be set to manual focus and pre-focused before taking the photos.

1. Using Multi-Camera to trigger the cameras: This can be done by selecting “Gang camera shutter releases together” in preferences and then pressing the “Release” button in the main window. Multi-Camera instructs each camera to take a picture as quickly as possible and each camera will be triggered in turn with a delay of approximately 1/6 sec between each camera. This means if there are 18 cameras it will take approximately 3 secs from when the first camera takes a picture until the last camera takes a picture.
   When capturing video the cameras will start one after the other with a delay of approximately 1/10th sec between each camera. Better video synchronization can be achieved using Canon EOS-1D C, Canon EOS-1D X and Canon EOS 5D Mark III cameras by triggering them using the remote release connection.
2. Triggering the cameras using the remote release connection: Canon EOS cameras have remote release sockets which allow the camera to be fired by simply using a switch. Multiple cameras can be fired at the same time by plugging cables into the remote release socket of each camera and wiring these together to a master switch. The cameras won’t all trigger at exactly the same time due to variations in the response time of each camera but they will usually all fire within approximately 1 ms to 5 ms of each other (the variation depends on camera model, lens type etc.). This variation can be reduced by activating the auto-focus via the remote release cables just before taking the photo.
   This technique can also be used to start and stop video capture when using Canon EOS-1D C, Canon EOS-1D X or Canon EOS 5D Mark III cameras. To enable this the cameras need to be setup so that the shutter release button is configured to start/stop video capture (please see the camera instruction manual for details on how to set this up). The 5D Mark III must also be set to movie mode by setting the movie/camera switch to the movie position.

Using the remote release socket to fire multiple cameras at once

The remote release sockets on EOS cameras are either a proprietary three-pin socket (higher end camera models) or a simpler standard 2.5mm jack plug with three connections. Both socket types work in exactly the same way and provide a way of remotely sending shutter release half and full press signals to the camera. Remote release switches and cables can be bought as accessories from Canon or more cheaply from eBay.

The remote release switch has two positions similar to the camera’s shutter release button. Half-pressure on the release switch activates the camera’s auto-focus by connecting the “Ground” and “Activate AF” pins together. Full pressure on the release switch releases the camera’s shutter by connecting the “Ground” and “Release Shutter” pins together. It isn’t necessary to activate the auto-focus in order to release the shutter and a picture can be taken by only connecting the “Ground” and “Release Shutter” pins together. Activating the auto-focus releasing the shutter puts the camera into a heightened state of readiness and will reduce the variations between cameras.

I have two long video clips on two different tracks in my timelines, both starting at the same time, and I would like to alternate between them (see a bit of track 1, then a bit of track 2, then track 1. ).

The only way I can think of for now is to cut the track with the greatest number when I want to show the one below, but then I loose some data and it gets hard to change my edit points.

Is there any standard way of doing that (for instance make the track with the greatest number transparent. )?

You can use the multi-camera feature in Premier to achieve this.

To easily synchronize footage from all cameras, make sure each camera records a sync point using a clapper slate or other technique. Keep each camera recording to maintain synchronization. After you capture the footage in Premiere Pro, use the following workflow to edit the footage:

1. Add clips from multiple cameras to a sequence.

Stack the clips from each camera on separate tracks of a sequence. (See Add clips for multi-camera editing.)

1. Synchronize the clips in the sequence.

Mark the sync point with numbered clip markers, or reassign the sync point for each camera to a specific timecode. (See Synchronize clips.)

1. Create the multi-camera target sequence.

The final edits are made in a target sequence. You create the target sequence by nesting the sequence of synchronized clips into a new sequence. Then you enable the clip in the target sequence for multi-camera editing. (See Create a multi-camera target sequence.)

1. Record the multi-camera edits.

In the Multi-Camera Monitor, you can view the footage of all four cameras simultaneously and switch between cameras to choose footage for the final sequence. (See Record multi-camera edits.)

1. Adjust and refine edits.

You can rerecord the final sequence and substitute clips with footage from one of the other cameras. You can also edit the sequence like any other sequence—using the standard editing tools and techniques, adding effects, or compositing using multiple tracks. (See Rerecord multi-camera edits and Adjust multi-camera edits in a Timeline panel.)

If you like it more visually explained, take a look at this video:

We’ve heard our customers asking about multi-camera streaming when using webcams like the Logitech C920 and Logitech C922 . We’ve also heard setup isn’t always that intuitive – or that software updates are impacting multi-camera streaming settings.

We hear you! And we want to be sure you have the tools you need to succeed. To get started, check out this step-by-step video to help you set up your cameras the way you want them.

We also know you’ve got questions about drivers, software and more. Below are a few most commonly asked questions and answers.

What is the impact of using standard UVC drivers vs Logitech drivers?

Logitech drivers were developed before UVC drivers were optimized for webcams. Today, standard UVC drivers are perfectly suitable for controlling the settings of multi-camera streaming while maintaining a stable environment. Video quality remains uncompromised.

Then why am I having issues with my C920 webcam and UVC drivers?

The Logitech C920 webcam works with Logitech Webcam Software (LWS), which was specifically designed to work with Logitech drivers. As a result, using the Logitech C920 with a standard UVC driver prevents the LWS from working correctly. As an alternative, we recommend the following applications:

-Windows 8 and 10: Microsoft Camera App (installed by default)

-Windows 7: OBS or XSplit Broadcaster

-Mac: Quicktime or OBS

Additionally, you’ll want to be sure your webcams are plugged directly into the PC USB port, as USB hubs may limit the bandwidth available.

Does this also apply to the Logitech C922 webcam and/or Logitech BRIO 4K Pro Webcam?

No. These webcams use standard UVC drivers.

I stopped using LWS, and now I want to use it again – is it possible to go back?

It is. You can reinstall Logitech Webcam Software 2.8 from our website .

When is the next update planned for LWS?

Because UVC drivers are now optimized for webcams, there is no longer a need for LWS. As mentioned above, we recommend recording applications such as:

-Windows 8 and 10: Microsoft Camera App (installed by default)

-Windows 7: OBS or XSplit Broadcaster

-Mac: Quicktime or OBS

For gaming, you may also want to download Logitech Gaming Software to adjust your settings.

How many cameras can this control? I do not mind paying for the app but is there a try before you buy version?

The theoretical limit is the Bluetooth device limit (I think it’s 50). I have tested the app with 6 GoPro cameras.

Can you switch between live previews?

No, the Bluetooth mode supports only basic camera controls but no live preview.

Any idea if this works with hero 8s?

The app is compatible with the Hero 8 camera.

Thanks for the swift reply!

Will I be able to have multiple GoPro’s running to YouTube live into the same “Event”? For example, I want 6 GoPro’s capturing the same thing from different angles, all streaming to YouTube Live.

You can control (e.g. start/stop recording) all cameras with the app at the same time. For streaming from multiple cameras you need an USB HDMI adapter for each GoPro.

How does the setup look… any YouTube videos on that…

You can find demo videos on under “YouTube demo videos”.

If I’m filming outside and I don’t have access to a Wifi Connection, can I change and save the settings manually and then use the app to start recording in sync?

You can setup and save all settings on each GoPro and then use the app to start recording with all cameras.

If I run a hotspot on my mobile device and connect all the gopros to the hotspot. is there a way to see all the live feeds on one screen. Like a director’s view? It would be cool in the field to monitor all the camera operators from my device.

What GoPro model are you using?

This is sweet! I try to run 3 cameras simultaneously when I’m out kayak fishing.

Does your app sync time with the cameras?

I use a lot of power because of the darned WiFi needs of the GoPro app. I would love to extend my battery life and reduce the heat of my cameras when they are out in full direct sun.

The app does not sync the time of the cameras. It’s best to make some noise (e.g. clap your hands) so that you have a point of reference for synchronization later in your video editing software.

Thanks for the quick response.

The challenge is having 30 to 50 files for each camera per outing and the files always having the default time from the camera. I guess I’ll have to take the time to manually input the time.

I’ll still purchase your software as turning off wifi alone is a big plus.

Any new features on the horizon?

On which system are you planning to use the app (iOS, Android, Windows, etc.)? Do you have a specific feature in mind?

IOS. I don’t have a specific feature because I haven’t used your app yet. I’ll let you know when I have time with it.

Whether you’re shooting a movie, a news broadcast or a commercial, it’s always an advantage to use multiple cameras. Being able to switch between different camera angles makes your productions look much more professional during live broadcasts. Multi-camera setups also make post-production much easier because editors will have numerous camera angles to choose from when putting videos together. But as we all know, not all cameras are made equal. Some cameras are better suited for multi-camera production than others. Recently, Sony released three new camcorders, the PXW-Z90V, HXR-NX80 and FDR-AX700, all offering a ton of valuable features for any multiple camera setup.

With the PXW-Z90V, HXR-NX80 and FDR-AX700, Sony wants to make it easier on multi-camera operators by allowing their camera trio to work seamlessly with their MCX-500 live streaming and production switcher, which Sony described as a compact, cost-effective switcher that will ease the burden on operators and make it easy for one operator to run a multi-camera live event. The MCX-500 switcher promises support for mixing between eight video sources with four stereo embedded audio channels and two XLR inputs. It features a dedicated title input, up to nine video inputs and five stereo inputs including XLR. For all of you multi-cam live streamers out there, Sony says that the PXW-Z90V, HXR-NX80 and FDR-AX700 can make multi-camera live streaming possible on Ustream, Facebook Live and YouTube — or record your production internally to the MCX-500.

In addition, with the MCX-500 switcher and Sony’s RM-30BP, tally icons will appear on each camera’s LCD panel and viewfinders. When there is a red icon, camera operators will know their shot is live, and when there’s a green icon, it is indicates that the shot is in preview mode.

Additionally, users can synchronize timecode among multiple camcorders. This is a very important feature for multi-camera setups because timecodes help you match up shots shot at different angles based on an actual recording time, rather than more fallible techniques like aligning audio. With the PXW-Z90V, HXR-NX80 and FDR-AX700, you use a wireless timecode link and synchronize the camera’s timecodes using Sony’s free Content Browser Mobile 3.0 app and optional CBKZ-WTCL update, compatible with devices running iOS (9.0 – 10.3) or Android (4.4 – 7.1) operating systems.

One of the major ways that Sony believes that the PXW-Z90V, HXR-NX80 and FDR-AX700 will help multi-camera operators is by making their workflow more efficient. They look to do this by providing dual memory card slots that allow for features like proxy recording and relay recording. Proxy recording helps workflows by creating a highly compressed, low resolution version of a much higher resolution video. The smaller video is useful because it’s quicker to send over TCP/IP networks and can be viewed quickly for things like editing or scripting. As for relay recording, it’s a process that allows your camera automatically switch to a second memory card when the current memory card runs out of space. This is a very efficient way to record because it allows you to continually record and switch out memory cards without any interruption to your recording. Sony’s the PXW-Z90V, HXR-NX80 and FDR-AX700 also support simultaneous backup recording that lets you to film on two memory cards at the same time so your footage is safe if something happens to one of your cards. And as said before, the cameras support timecode (TC) and also user bit (UB) to help match shots and keep your workflow running smoothly.

Lastly, the new camcorders have a REMOTE terminal, a Multi-Interface Shoe and HDMI Type A that Sony says will allow for enhanced user operability.

The PXW-Z90V, HXR-NX80 and FDR-AX700 have the potential of becoming the new stars of multi-camera productions. By working seamlessly with Sony’s MCX-500 switcher, they promise to make it easier for one operator to operate a multi-camera setup. And the camera’s features like proxy recording, relay recording and TC/UB support really sweeten the deal.

You can learn more about the PXW-Z90V, HXR-NX80 and FDR-AX700 on their official spec pages. You can also see some sample footage of the PXW-Z90 and the HXR-NX80 below:

Cut the cables and forget hardwiring all of your recording equipment together. Distributed recording with Panopto will change the way you capture events.

How distributed recording works.

Capturing multiple camera angles at a single event or presentation used to require a truckload of equipment. Literally. Different cameras would need to be physically cabled to a single control station, and a myriad of complex switchers, transcoders, and other technology was needed to synchronize all those disparate feeds.

Distributed recording with Panopto does away with all that. With distributed recording (also called multi-machine recording), you connect each of your cameras and audio sources to a web-connected computer and/or mobile device that has Panopto installed. Instead of tying everything together with cables, each computer or mobile device can be positioned independently. From there, simply set each computer to record to the same Panopto session. Panopto automatically takes care of the rest, synchronizing every feed into a single, seamless professional production.

Cut the cables and the setup time.

Record quarterly events, monthly town hall meetings, or your annual company user conference with less setup time and at a fraction of the cost required to hire an outside video production company.

Distributed recording means you no longer need to connect every device and every computer together with hundreds of feet of cable in large rooms or auditoriums with complex AV setups. Record the presenter’s slides and audio from the front of the house, capture video of the presenter on stage from the back of the house, and let Panopto sync your feeds for you in the cloud.

“It’s amazing how simple it was — with Panopto, everything just worked. Instantly, we had a repeatable and reliable process we could use for [live streaming] all our team meetings going forward.”

Director of Information Technology, Global Sporting Goods Manufacturer

Record from different locations and networks.

Capture and mix video from global executives for your next on-hands meeting or present a remote guest speaker without complicated setups or configurations. Panopto’s distributed recording capability enables you to capture and sync video from presenters in multiple locations. Simply use Panopto to record in both locations and save the feeds to the same session.

Do it live.

Live stream multiple camera angles with distributed webcasting.

Whether you’re streaming live or recording for on-demand viewing later, you can use Panopto’s distributed recording capability to sync multiple AV feeds from anywhere into one single broadcast. Live streaming is as simple as recording multiple feeds to the same session and checking the live stream option in Panopto. All live streams are automatically recorded and then uploaded to your video library where any word spoken or shown in them can be searched and played back on any device, at any time.

The Slim 3U is a board level camera designed for OEM integration in computer vision, multi-touch screens/surfaces, and custom tracking applications. It is fully customizable, with a variety of optional components and features. Software support includes the free Camera SDK, which provides complete control and access to camera settings.

A curved multi-touch screen

Six Slim 3U cameras were used in making the Reality Touch Theatre at the University of Groningen.

Fast, precise, and efficient capture

The Slim 3U is capable of capturing fast moving objects with its global shutter imager and 120 FPS capture speed. By maximizing its 640 × 480 VGA resolution through advanced image processing algorithms, the Slim 3U can also track objects down to sub-millimeter movements with repeatable accuracy.

Components a la carte

Build your SLIM piece by piece, optimizing it as you see fit. Custom building your camera gives you the flexibility to create a hardware solution that is tailored for your own application, satisfies your unique spec, and maximizes cost-efficiency. Optional components include:

• Aluminum case with CS lens mount and 1/4″-20 tripod thread
• Filter options (800nm pass filter, Filter Switcher, empty filter plug)
• Lens mount adapter (CS to M12, CS to C—only available with SLIM case)
• M12 lens (3.5mm, 4.5mm, 5.5mm)
• Input/output (Sync break-out cable, Micro 9-pin connector)

Camera control

With OptiTrack’s Camera SDK you can access a variety of Slim 3U settings for greater control over what your cameras capture and what information they report to the software application. Available settings include:

• Image processing type
• Frame rate
• Exposure
• Threshold
• Filter switching
• And more.

Precision Grayscale | Segment | Object

Precision Grayscale (orange) vs. Segment (green)

On-camera image processing

In addition to providing raw and MJPEG grayscale video, SLIM cameras can process and threshold data on-board, creating a variety of video modes deliverable to your PC, including:

• Precision grayscale – Most precise object detection. Sends grayscale object information to the PC for calculation of location, size, and roundness using our most precise processing methods.Provides greater accuracy than other modes, but consumes more CPU resources and USB bandwidth.
• Segment – Balanced object detection. Similar to Precision Grayscale, Segment processing streamlines object information for more CPU-efficient marker detection. Provides a balance between precision and USB bandwidth use.
• Object – The most CPU-efficient object detection. Provides more efficient USB bandwidth utilization, but delivers less information to the PC than other modes.
• MJPEG-compressed grayscale – Full resolution grayscale frames, compressed on-camera for highly scalable scene video capabilities.
• Raw grayscale – Full resolution, uncompressed grayscale.

MJPEG compression

Transmit MJPEG-compressed grayscale video at full frame rate and full resolution with 1/10th of the USB bandwidth of uncompressed video. MJPEG compression enables multiple cameras to stream video to the same PC, offering scalability superior to raw grayscale video.

OptiHub

Improve power regulation, camera syncing, tracking distance, and more.

Camera Synchronization

Up to 24 SLIM cameras per PC can synchronize their shutters to expose at exactly the same time. Each synced camera can operate in different video modes with individually customized camera settings. Utilize OptiHubs in your sync chain to enable external syncing capabilities.

Filter Switcher technology

Upgrade any Slim 3U camera with the same Filter Switcher technology found in Flex 3 cameras, enabling visible spectrum video in addition to standard IR imaging. FS-enabled cameras are equipped with a solenoid that can be controlled in-software to extend or retract the infrared lens filter. OptiTrack’s user-changeable, polychromatic M12 lenses are specially designed to remain in focus in both the visible and infrared spectrums.

OEM integration

Incorporate Slim 3U cameras into OEM tracking or computer vision applications via the free Camera SDK.

The process for creating a multicam project is outlined below. The procedures are presented in rough chronological order, but you can rearrange the order to suit your workflow.

Step 1: Shoot an event with multiple cameras and record appropriate sync information

A multicamera shoot uses multiple cameras to record the same subject or event from different angles and distances.

For multicam projects, it’s a good idea to set the date, the time, and the time zone on your camcorder or recording device before you shoot footage. This provides useful information to Final Cut Pro during the automatic multicam clip creation process.

In professional multicamera shoots, each camcorder or VTR receives the same timecode from a master timecode generator, or you can jam sync the timecode generator of each camera at the beginning of the shoot. If you’re using consumer camcorders, which can’t accept external timecode, you need to record a visible or audible cue, such as a clapboard closing or a camera flash, on all cameras. You can use this cue to sync the angles in your multicam clips.

Because you can use the sophisticated automatic audio sync feature in Final Cut Pro to help ensure multicam sync accuracy, it makes sense to record audio on every camcorder and recording device in your multicam production. (Clear audio recordings provide the best results.)

Step 2: Import media into Final Cut Pro for a multicam edit

Although importing media for multicam projects is the same as importing for any other project, there are steps you can take during importing to help streamline the multicam workflow.

Step 3: Assign camera names and multicam angles

You can use the Camera Name and Camera Angle metadata tags to automate and organize your multicam workflow. It’s recommended (but not required) to apply these tags to your event clips before you create an actual multicam clip.

Step 4: Create multicam clips

You create multicam clips from selected event clips (similar to the way you create auditions and compound clips in the browser). Whether you do it manually or have Final Cut Pro do it for you automatically, creating a multicam clip involves three fundamental steps:

Create angles (containing one or more clips each).

Arrange the order of clips within each angle.

Sync the angles using a common sync point.

If you know what kind of metadata your source media has, you can create multicam clips using manual methods even faster than with the automatic methods. See Add camera names and angles in Final Cut Pro and Create multicam clips in Final Cut Pro.

Step 5: Cut and switch between angles in the angle viewer

After you create a multicam clip, you can watch all angles simultaneously in the angle viewer while switching or cutting to different angles in real time. You can cut and switch video and audio at the same time or independently. For example, you can use the audio from angle 1 while switching the video between angles 1 to 4.

Step 6: Sync and adjust angles in the angle editor

You can open multicam clips in the angle editor to adjust the sync and the angle order or to add or delete angles. You can also use the angle editor to make edits to the individual clips inside a multicam clip (such as trimming, making color corrections, adding transitions, and so on).

Step 7: Edit multicam clips in the timeline

You can switch multicam angles directly in the timeline or the inspector, without opening the angle viewer. Although multicam clips have some unique properties, you can edit them in the timeline in the same way you edit any other clips.

What is the video quality?

Video quality is set using the Outputs tab. you can set the resolution as high as 720p. The recording bitrate can be set as high as 2000kbps. When record on all Cameras is activated, some devices can record as high as 1080p.

Does the app record when I am streaming?

By default, the app will record when streaming is taking place. If for some reason, the stream is interrupted, the app will display a message and give you the option to continue recording or abandon the current broadcast to try to stream again.

Can I manage FPS?

Adjusting fps settings may be required depending on your streaming video provider. Email [email protected] if your streaming provider requires a specific fps setting.

What file format are recordings saved in?

Video clips are saved in the .MOV file format with AAC audio.

Can I edit videos afterward?

You can send your video directly to iMovie on your iPad by opening the Recorded Media menu and selecting “Open In”. Otherwise, you can place the live video output in a non-linear editor like Final Cut or Premiere Pro to extract excerpts. If you want to re-edit the entire production, enable Record on all Cameras before you begin filming to capture ISO recordings from each camera angle.

When I move recordings to the camera roll does it make a copy of the video?

When you record a video using Switcher, the video is saved in the “Recorded Media” directory within the app. You can copy it to your Camera Roll to export the video using “Image Capture on your Mac. To save space on your iOS device, remember to delete videos that you have already transferred from your device. Otherwise, you may run out of room during your next production. Check out this Knowledge Base article for more detailed information: How do I copy video from my iOS device to my computer?

Can I put videos on my site?

The videos you create with Switcher Studio are managed by your Content Distribution Network. You own all content that you create using Switcher Studio. Select a streaming video video platform that supports RTMP to stream your video directly, or you can just record and upload later.

How big of a delay is there?

There is a signal delay of around 200ms (roughly 6 frames at 30fps). This latency is a short buffer to allow the app to synchronize video and audio as well as process the sources for optimal video output. When monitoring audio using headphones, you may notice that audio noticeably lags behind the realtime audio. However, this audio will sync with the video output in the Live pane to provide assurance that the live output had A/V sync.
