Which yields better quality ? possible, problems, produce, encode

andy

I am wondering. Which of the two will give me better quality :

A 2-pass encode with 130% compressibility check (the output file is undersized) or a 1-pass quality based encode with a Quantizer of 2 ?

I am talking about DivX 5.02 Pro.

Well they should give you the same resulting file, but alas, this is not the case. Due to minor problems in the codec, it will produce some frames with quantizer gt; 2 if you use bitrate based encoding, so you will get the best possible quality if you use constant quality.

This is only true for DivX 5.02! DivX5.03 will give you quantizer = 1(!) if you use bitrate based encoding, and both DivX3.11 and XviD will produce the expected quantizer = 2 even if you use bitrate encoding if the compression test is gt;100%.

Aha I see. I'll choose the QUANTIZER=2. Thanks.

DivX 5.03 really uses q1 in 2-pass encoding?! coo~l!
Thanks for the info! *thinking that my rips are better than I thought*
