from a 140 MB movie file, 130 of it is video and 10 audio. is that ok ? or should there be less audio ?
(program used: VirtualDub 1.5.8)
i'm using MP3 as compression. more exactly, the
56kBit/s 22050 Hz Stereo 7KB/s setting
but thats the highest one in the list.
there are two frequencies possible for stereo : 22050 Hz and 11025 Hz.
for 22050 Hz, there are several possibilities for bitrate (i think its supposed to be bitrate...) : 56kBit/s, 48kBit/s, 40kBit/s.
and for 11025 Hz :
32kBit/s, 24kBit/s, 20kBit/s, 18kBit/s
what would u suggest as best ? when i say best, i dont mean best sound quality, but to have an extreme minimum amount of space allocated to audio, but still at the point where the sound quality can be qualified as being "ok".

If you install the radium codec (see Doom's download section), then you can compress to 44.1 kHz (or 48 kHz) at 128 kbit/s. For a mono source you can use a lower bitrate.
