DivX5 Q&A

Q: Is DivX5 better than DivX3/DivX4/SBC/XviD/etc?
A: As Einstein said, everything is relative. So is the quality of video codecs. Some might find codec X more visually pleasing, others may prefer Y and both are right when they say "their" codec looks best but they should not try to impose that opinion on others because what may be right for them is completely wrong for others.

Q: How to best compare DivX5 to other codecs?
A: Encode a clip in CQ mode. Use the same mode for every codec. Rate control that's being used in 2 pass encoding may work different in various codecs and you have the ability to compress mixed with the rate control and you really should look at the ability to compress only.

Q: Where's the DivX5 guide?
A: http://www.doom9.org/gknot-main3.htm

Q: Where can I find more info about Divx5?
A: http://www.divx.com/support/divx/guide.php

Q: What's the difference between DivX5 standard and DivX5 Pro?
A: You can find the full specs of both versions here: http://www.divx.com/support/divx/guide.php

Q: Why is the codec no longer free?
A: This is an incorrect statement. The codec, even the Pro version, is still freely available for everyone to use. The money earned by the sales of the Pro version is used to pay MPEG-4 licensing fees. Here's a link that will give you more info about MPEG-4 licensing: http://www.mpegla.com/news_release31Jan2002.html. Also be aware that Apple is withholding their QuickTime6 software because of these licensing fees.

Q: Will the Sigma X-card play DivX5?
A: Yes and No. It will play DivX5 standard generated if it does not make use of GMC and QPel motion estimation. These two MPEG-4 features are not supported by the card. Here you can find the full specs of the card: http://www.sigmadesigns.com/products...ifications.htm

Q: Should I use the resize, crop and deinterlace/IVTC options in the codec or do them outside (e.g. resize in avisynth and use decomb)?
A: Definitely the latter. All these options are more or less the same as in DrDivX, a never released DivX4 encoding app by DivXNetworks, and they haven't worked that well (especially deinterlace/IVTC).. so you're better off using the tools you use for all the other codecs.

Q: How can I have both DivX4 and DivX5 installed on my system?
A: Please read this thread.
