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" mencoder tv:// -tv driver=v4l2:device=$DSVID:norm=$NORM:input=$SVID:alsa:adevice=$ALSA_SVID:audiorate=$RATE:width=$WIDTH:height=$HEIGHT -mc 0 -noskip -ovc lavc -lavcopts vcodec=mpeg4:vbitrate=$VRATE -vf crop=$CROPED_WIDTH:$CROPED_HEIGHT:$CROPED_X:$CROPED_Y,pp=lb -oac mp3lame -lameopts cbr:br=64 -o $F_SV_REC" 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.
