MPEg to DivX bit rate

[KrypticChewie]

When converting from MPEG to DivX what bit rate should be used? Meaning for what MPEG bit rate should the DivX bit rate be? The ratio if you will.

when i convert, i always use higher bitrate, to be sure i don't lose too much quality.

Whichever will land you the filesize that you are targetting.

There is no fixed rule for bitrates. Just make sure that you are not aiming for a larger filesize than the original .mpg file since there will be no quality increase.

So can one assume that if the bitrates are the same then the quality will be the same?
If so that would suggest that DivX and MPEG are the same quality.

No, since the codec that you are using is lossy (i.e. it discards information).


"If so that would suggest that DivX and MPEG are the same quality."

Again, no.

Because after conversion, the resultant DivX file would be missing some information from the original MPEG file.

The only time you want to use the DIvX codec is when you want to shrink an existing video file without losing too much quality (the recent MPEG-4 codecs are really good at keeping quality loss at a minimum).
