One camera is a video call. Two or more is a production. The jump is smaller than most people expect, and it is mostly about getting the pictures into one place.
Getting the cameras in
There are four routes and you will probably use more than one.
- USB cameras and webcams plug straight in.
- Cameras with HDMI or SDI output need a capture card. A single USB stick handles one; a multi-channel PCIe card handles four, eight or more on one card.
- Phones connect over Wi-Fi with a companion app. This is the cheapest extra angle you will ever add.
- Cameras too far to cable can use a small HDMI encoder that puts them on the network.
The multi-channel capture card is the important one. It is what removes the need for a hardware switcher — every camera arrives as its own source and the switching happens in software.
Plan your shots before you plan your cuts
Three angles that each do a job beat six that overlap. A typical useful set: a wide that establishes the space, a close that carries the speaker, and a third for detail — the audience, an instrument, the slides.
If you have a phone spare, put it somewhere a real camera cannot go. That is where it earns its place.
Match the cameras before you start
Different cameras produce different pictures. The cut between a warm camera and a cool one is the most noticeable thing in an otherwise good broadcast.
Pick the camera you like the look of and bring the others toward it. Automatic white balance gets most cameras close in one click; refine from there and cut between them as you go, because the differences that survive a cut are the ones worth fixing.
Switching without looking amateur
Use Preview and Programme. Line the next shot up privately, check it, then take it. Never cut straight to air.
Cut on motion or on a change of speaker. Hold each shot longer than feels comfortable — four to six seconds minimum. Fast cutting reads as nervousness, not energy.
Pick one transition and stay with it. Cut for pace, a short dissolve for calm.
Record every camera separately
Turn on isolated recording. Each camera writes its own file alongside the programme mix.
This is what makes a live event editable afterwards. Without it you have one mixed file and every bad cut is permanent. With it, the live switch becomes a rough cut you can improve.
The rehearsal nobody does
Run the whole thing for ten minutes the day before, recording, with the actual cameras in the actual positions. Almost every problem you would have had on the day shows up in those ten minutes, when fixing it costs nothing.
