[FFmpeg-user] Anyone having success capturing hours of 4k video, reliably and with low loss, using ffmpeg?

[Another Sillyname]

Yes, but honestly I think you are over simplifying it......

For example, are you intending to capturing scenes with high activity
that requires a much higher bandwidth and transcoding
capability?

Anyone can capture and transcode to say H265 even, 4K at 60FPS if you're
just capturing a black backdrop.

The capability exists and as you've stated the existing solutions can
be crazy expensive, but if you're going to homebrew a solution you
need to do some work/testing to make sure what YOU want to capture can
be done within YOUR budget.
