Divx V.S. Mpeg

[hk10Mbps]

I have no idea why people like to choose Divx to encode their movie. What is the advantages over Mpeg1 and 2? Please do a brief comparison.

Smaller file sizes

You can get a full 2hr movie into 700mb (1 CD) with DivX, and at comparable quality MPEG2 would need 2 CDs (1400MB)

Only plus side is that MPEG1 and MPGE2 can be played in most standalone DVD players, DivX can't

Are u sure Mpeg1 or 2 don't have that high compression ratio at same quality?

Yes. He's sure. Divx has a higher compression ratio. Divx is based on the work done for the mpeg4 codec.

As a matter of fact, it is debateable that a 2CD rip in MPEG2 would equal a 1CD rip in DiVX. In many cases I've tried, 3 or more CD rips would be necessary for the equal quality of a DiVX 1 CD rip.

A good site for more information and guides on ripping to DiVX is www.doom9.org.

PS The best quality in the smallest space I've found is DiVX v5 with Ogg Vorbis sound track (IMO). The new OGM media format for ogg is pretty darn slick, but since it's new, the tools aren't as automated...

How about using VBR when encoding in Mpeg?

What is the relationship between Divx and Mpeg 4?

A few years ago when MPEG-4 was still being hashed out Microsoft released a codec based upon it and made it part of their media tools package using ye olde Audio Video Interleave transport. They soon chose to restrict coding only to their new Advanced Streaming Format transport which they were pushing at the time. ASF added some overhead for streaming and could not be edited with common AVI tools. But a simple hex edit could change that and so this preliminary MPEG-4 continued to catch on as each new version was quickly hacked and distributed throughout the AV comminity. Someone went so far as to change the codec's name to "DivX ;-)" as a joke (after the failed subscription alternate to DVD) and include an installer package so Microsofts's was not even needed anymore. They even messed around with hacking Windows Media Audio but it never really caught on when faced with MP3. Eventually they and others were recruited to develop an MPEG-4 compatible codec independently to ca$h in on its popularity. So now we have DivXNetworks, Inc. So, to answer your question DivX is based on and is compatible with the MPEG-4 standard and I suppose would not have existed if the ISO had finalized it and agreed on licensing sooner.
