Hi. Probably I'm not understanding the guide, but I found strange , on http://www.doom9.org/index.html?/mpg/quenc.htm , the phrase:
.......................................................................................................
If you haven't calculated the bitrate yet, here's a quick and dirty way how to do it: 9800 - total audio bitrate. As an example if you have 1 2.0 kbit/s AC3 track (192kbit/s), 2 5.1 kbit/s AC3 tracks (384kbit/s each) you'd get to a max bitrate of 9800 - 192 - 2*384 = 8840 kbit/s.
.......................................................................................................
What? For SVCD, the final purpose is to make a movie, of a determined length, to fit into a 80' CD-R (A MPEG-2 about 830 MB). Just to make a check, a 2500 kbps (in the main screen, I ignored the 2nd screen 'advanced options') a 5' AVI became a 107 MB mpeg!
Now, let's suppose we have a 90' AVI movie. I would like them to fit into 2 80' CD-R.
Therefore, my question is:
1) In this case, can I select a range or do I have to split the big AVI into 2 small 50' files?
2) Is there a sort of algorithm, like the one used by FitCD, which tells you: "if you use QuEnc to encode a 480x480 AVI into a MPEG-2, if the movie's length is L, the maximum bitrate you can set is: B/L" ? (and you'll encode a, say, 830-835 MB MPEG-2 file)
Thanks in advance...
