Two questions about VLC's saved-from-capture-device output files

[Gronky]

1- The resultant AVI files on my system (from a 1080x720 CCTV DVR) are about 1GB per minute (!) of video; is this normal?

2- Both FFMPEG and AVIdemux are unable to recognize/load these output files, although they playback perfectly with VLC.

BTW the VLC version I'm using is 3.0.17.4 Vetinari

1) Sounds about right if you're recording raw uncompressed video.

2) Probably a limitation of those tools. Wrong venue.
