G'day Ed -
Glad you got your multi-cam functioning. I tried to replicate it here (without an LG20) but whatever combination I tried worked.
About production formats & profiles...
You're right - the profiles as they're list start at the lower end & work to the top.
If you look at an AVC H.264 MPEG-4 profile, it'll state something like "
MPEG-4 1920 x 1080/30p (16Mbps)".
- MPEG-4 is the wrapper
- 1920 x 1080 is the video resolution (frame size)
- 30 is the framerate & the "p" is for progressive
- 16Mbps is the (average) video bitrate, an indicator of quality.
It's a complicated thing, but the rule of thumb is to always produce to about the same quality (properties) as your input material. If you're using a mixture of (say) UHD clips at 60Mbps & HD clips at 28Mbps, it's probably best to produce to the lower quality - 1920 x 1080 @ 28Mbps.
Cheers - Tony
