The right workflow depends on how many sources you have, whether they use HDMI or SDI, and whether your switcher sends video to a computer or streams directly.
How a multi-camera live workflow fits together
The basic signal path is: cameras and audio sources feed a switcher; the operator monitors and cuts those sources into a program; the finished program goes to streaming software or a direct-streaming output, and optionally to a recording destination. Details vary by hardware model, so confirm the exact capabilities and connections in its documentation.
- Plan camera positions, roles, and output formats.
- Choose a switcher that accepts the planned number and type of sources.
- Connect and label the cameras, then confirm each feed appears.
- Monitor the inputs and program, and switch between shots.
- Route audio and check it in the finished program.
- Send the program to streaming software or a supported direct-streaming path; configure recording if needed.
- Rehearse the complete signal path before the event.
Plan camera roles and confirm outputs
Give each camera a distinct job
Decide what each angle contributes—for example, a wide view that establishes the scene and tighter views for speakers, performers, or gameplay. Camera placement should make cuts useful rather than merely increase the source count. Confirm that each camera can supply the output format your production requires.
Match the switcher to sources and connectors
Count the sources you need at the same time, including any planned additions, and check their output connectors. HDMI and SDI are different signal paths; choose inputs and cabling that match the actual equipment. Blackmagic Design’s ATEM Mini and ATEM SDI setup guides describe product families with four- or eight-input models, depending on the unit; these are examples, not a complete comparison of switchers.

Connect, monitor, and switch the cameras
Connect and identify every input
- Connect each camera to a compatible switcher input.
- Label the inputs so the operator can identify each shot quickly.
- Check that every source is visible before the production begins.
Use multiview only when your model supports it
A multiview display can let the operator see several inputs and the program at once, but its availability is model-specific. Blackmagic documents multiview on specified ATEM SDI Pro and Extreme models. Check the exact switcher’s feature list and display connection rather than assuming the feature is present.
Make cuts and transitions on the switcher
The operator selects sources using the switcher’s panel or software control. Blackmagic’s ATEM Mini guide describes both its built-in control panel and ATEM Software Control. Set up the chosen control method in advance and rehearse the shots and transitions the show needs.

Route and check audio
Choose between the switcher’s audio inputs and controls or an external mixer based on the microphones, routing, and operator responsibilities. ATEM Mini and ATEM SDI setup materials document audio-source connections, and the ATEM Mini manual covers Fairlight audio workflows. Those materials do not establish one gain setting or lip-sync procedure for every production.
Recommended Free Tools
- Check each microphone and other audio source in the finished program path.
- Listen while monitoring the program, not only at the camera or mixer.
- Rehearse the complete audio and video route so problems are found before the live event.
See the ATEM Mini manual for its model-specific audio controls.
Choose how the program reaches streaming or recording
Switcher to computer and streaming software
Some switchers provide a USB output that a computer can use as a webcam source for video software. You then configure the software and destination on the computer. Blackmagic documents this kind of USB webcam output for ATEM SDI and ATEM Television Studio setup paths.

Direct streaming from supported switchers
Specified ATEM SDI Pro and Extreme models support direct streaming over Ethernet. That is a different configuration from sending USB video to a computer running streaming software; verify the precise model and follow its setup guide.
Recording is a separate requirement to verify
If you need a recording as well as a live program, check whether the selected switcher and the rest of your signal path support the recording you need. Do not infer recording or multiview capabilities from the product family name alone.
For setup specifics, consult the ATEM SDI guide and ATEM Television Studio guide. An OBS Project forum resource on ATEM Mini and OBS describes one possible arrangement; it is an example, not the only way to combine a switcher and software.

Choose a workflow by production needs
| Decision | What to check |
|---|---|
| Inputs | How many simultaneous sources are needed, and might the count grow? |
| Connectors and routing | Do camera outputs and switcher inputs match (HDMI or SDI), and does the cabling suit the venue route? |
| Switching and monitoring | Does the operator need a hardware panel, software control, or multiview? Is multiview included on the exact model? |
| Streaming and recording | Do you need USB webcam output to a computer, direct Ethernet streaming on a supported model, recording, or a combination? |
| Audio | Are the switcher’s inputs and controls sufficient, or is an external mixer or separate audio operator more suitable? |
| Synchronization | Check the specific camera and switcher manuals for the intended use. |
Synchronization features are not universal. The ATEM Television Studio switchers manual describes full-frame input resynchronizers for that family and says genlock is not needed for its cameras and sources. This should not be generalized to other switchers or taken as a solution to every timecode or post-production synchronization need. See the ATEM Television Studio switchers manual.

The operator cannot see all the camera feeds
Check whether the exact switcher model supports multiview and whether its display output is connected as required. Do not assume every model in a product family includes it.
The stream does not receive the program
Identify which output path you configured: USB to a computer and streaming software, or direct Ethernet streaming on a supported model. Confirm the selected device, software input, or switcher setup matches that path.
Audio is absent or not right in the program
Check the selected audio source and its route through the switcher or external mixer, then monitor the finished program. Rehearse the full path; a universal gain or sync setting is not established for these setups.
Unsure whether sources need genlock
Consult the exact switcher manual. The resynchronizer information for ATEM Television Studio is specific to that family and does not establish requirements for other equipment or workflows.
