Provided you don't hit your maximum bit-rate limit (-b 4000) that you've chosen, yes. > I want to encode about 43 minutes of video with 720x480 final size (4:3 > letterboxed) so that I have a resulting file size (video only) of about > 950 MB (average of 3000 KBit). > > I tried -f 8 -q 4 -b 4000 -K tmpgenc -D 10 and got 710 MB file size.

If you go to the high-quality matrix (-K hi-res) you will get an even larger file size for the same parameters. The tmpgenc matrices are intended for reducing the bitrate while still producing a quite reasonable quality picture. > Is it logical to reduce -q further until I get to my wanted file > size, if -b can be kept 25% above the average? ------------------------------------------------------- The SF.Net email is sponsored by EclipseCon 2004 Premiere Conference on Open Tools Development and Integration See the breadth of Eclipse activity.
