Does anyone know how to convert the MPEG-4 AVC (H.264) to Divx , avi ( MPEG-4 SP), or any other mpeg compression?

About H.264

H.264, or MPEG-4 Part 10, is a high compression digital video codec standard written by the ITU-T Video Coding Experts Group (VCEG) together with the ISO/IEC Moving Picture Experts Group (MPEG) as the product of a collective partnership effort known as the Joint Video Team (JVT). The ITU-T H.264 standard and the ISO/IEC MPEG-4 Part 10 standard (formally, ISO/IEC 14496-10) are technically identical, and the technology is also known as AVC, for Advanced Video Coding. The final drafting work on the first version of the standard was completed in May of 2003.

H.264 is a name related to the ITU-T line of H.26x video standards, while AVC relates to the ISO/IEC MPEG side of the partnership project that completed the work on the standard, after earlier development done in the ITU-T as a project called H.26L. It is usual to call the standard as H.264/AVC (or AVC/H.264 or H.264/MPEG-4 AVC or MPEG-4/H.264 AVC) to emphasize the common heritage. The name H.26L, harkening back to its ITU-T history, is far less common, but still used. Occasionally, it has also been referred to as "the JVT codec", in reference to the JVT organization that developed it. (Such partnership and multiple naming is not unprecedented, as the video codec standard known as MPEG-2 also arose from a partnership between MPEG and the ITU-T, and MPEG-2 video is also known in the ITU-T community as H.262.)

The intent of H.264/AVC project has been to create a standard that would be capable of providing good video quality at bit rates that are substantially lower (e.g., half or less) than what previous standards would need (e.g., relative to MPEG-2, H.263, or MPEG-4 Part 2), and to do so without so much of an increase in complexity as to make the design impractical (expensive) to implement. An additional goal was to do this in a flexible way that would allow the standard to be applied to a very wide variety of applications (e.g., for both low and high bit rates, and low and high resolution video) and to work well on a very wide variety of networks and systems (e.g., for broadcast, DVD storage, RTP/IP packet networks, and ITU-T multimedia telephony systems).


How can i play H.264 files?

You can utilise the following software to play h.264 encoded files back on your system.

-- VLC media player
-- Windows Media Player v9+ with ffdshow codec pack
-- Nero Showtime
-- Apple Quicktime 7
-- Bsplayer
-- Windvd
-- Power DVD
-- Divx Player v6.0

Hardware Player

-- Kiss DP-600

How do i create H.264 files?

At the time of writing their are not too many apps available that will encode to this codec.
Some of the more popular choices include:

-- Nero Recode v2
-- Gordion Knot
-- MainConcept H.264 Encoder


How to convert H.264 files to Xvid/Divx and more!

Ok this is a long procedure so read carefully, step by step.

Step one: You will need to following software.

Virtualdub 1.6.5
Avisynth 2.5
FFDSHOW (newest build available)

Step two: Ok once u have installed the above apps its time to get into the nitty gritty side of script editing.
Open up notepad (or any basic text editor).
type the following in:

directshowsource("x:\file.mp4",convertfps=true)

replace 'x' with your relevant drive letter. replace file.mp4 with the name of your own .mp4 file. convertfps just keeps the file in sync (audio and video).
now save the file as a .avs
example: test.avs

Step three: ok now open this file in virtualdub. in should open without any errors. both the input and output video displays will show.

Step four: now just go about encoding this file like any other file in virtuadub.

Wasnt that hard now was it!!

Does TMPEnc not do it? Last I recall it did.

SouperComputer

virtualdub.

install x264 and Divx, start processing and allow to simmer

I tried TMPEnc but didn't work for me....

@salupa, thanks for your reply. followed your instructions, installed all three softwares but kept getting the script error in virtual dub, for some reason:eek: . But then i
played around with nero 7 premium and exported the file as a video file and it worked just fine. You can actually choose the desired format too, so it can be used as a converter...:D

cheers...
