Hi Terje, I have used a cheap chinese USB video grabber to digitise VHS. But I cannot remember the type. I used VLC, which worked fine, but OBS should also work. I had loaned the grabber, and have not tested if Cinelerra-GG could use it directly. I cannot remember if video and audio showed up as two different devices or not. If the audio is not a separate device, then I doubt Audacity can record with it. Hi, On linux, you can use mencoder to grab audio + video and specify any video input and output file and format you want to use. It is much more easier to use than ffmpeg. Something like:
DSVID="/dev/video0" NORM="PAL-BG" SVID="2" # the input on the video device ALSA_SVID="hw.1" # the ALSA card RATE="48000" # [Hz] same than the sound card for best quality WIDTH="634" # must be divisible by 16 HEIGHT="472" # must be divisible by 16 VRATE="4500" # [kbits] between 4 (small file) and 16000 (big file) CROPED_WIDTH="628" # must be divisible by 16 or 4 CROPED_HEIGHT="448" # must be divisible by 16 or 4 CROPED_X="6" CROPED_Y="16" F_SV_REC="/home/dom/movie.avi"

For the video quality of VHS, if the player or the video camera have a s-video output, and the video card a s-video input, the final record will be better than with "standard" VHS quality.
Cheers, Dominique
Interesting about Mencoder, but sorry - there is no S-Video IN port on my video card inxi -Fzx | grep Graphics Graphics: Device-1: NVIDIA GK208B [GeForce GT 730] vendor: ASUSTeK driver: nouveau v: kernel bus ID: 01:00.0 Terje J. H
