What source?
What cabling?
What filtering will you be doing?
What final output (DVD, Youtube, etc)?
65000? Do you mean 6500 kbps?
card: Compro M1F
software capture: Compro DTV4
cabling: S-Video
output: DVD (mpg)
filtering: what do u mean by filtering i didn't understand
6500 yes
Since your target is DVD you are talking MPEG 2 encoding with bitrates below ~9000 kbps. If you have less than 1 hour to put on a single layer disc (4.7 GB) you can simply use constant bitrate encoding at ~9000 kbps. The max bitrate allowed is about 10,000 kbps for video + audio + subs. For more than an hour on a single layer disc you should use a bitrate calculator to determine the appropriate bitrate. Then use a 2-pass variable bitrate encoding with the average bitrate set to that value. 2-pass encoding isn't possible while capturing.
Basically, the higher the bitate the better the quality. The basic relationship between bitrate, file size and running time is:
file size = bitrate * running time
Filtering refers to adjusting the picture. Things like contrast, color, sharpening, noise reduction, etc. Filtering can be too slow to do while capturing. If you need to filter, and your card supports uncompressed or losslessly compressed video you should use that. Then filter your video and encode to MPEG 2 for DVD.
