The clips that the camera creates are massive MOV files, exactly 3,605,376 KB, and only 18 min long each (1920x1080p, 30fps, audio at 48kHz and 2304Kbps).
When I attempt "Intelligent SVRT", I get a message "No SVRT profiles available for the current project." I have not once been able to use "Fast video rendering technology", or "Hardware video encoder".
A 24 minute movie requires 90 minutes to two hours of time to produce on my system (core i5 processor, second gen, 32 GB RAM, AMD Radeon HD 6800 graphics card with 1GB dedicated RAM).
After producing the video into (about 5GB of raw MOV files) using HEVC, the filesize is only 1.6GB large - so I know there is some hefty compression going on. Is there something else going on?
Because these are recordings of live music, I'm very hesitant about a loss of quality, especially audio quality.
I will look into that tsMuxerGUI, though, it sounds promising.
