mpeg-4 question

Post by RETRO HELIX » Fri Oct 03, 2003 5:52 pm

I've noticed that a few people have converted their videos to mpeg-4 and was wondering if you could tell me what program to use, premier can transform from mpeg to mov but sucks at doing it, specially since it wont read audio codecs so the ending result gets about 65% bigger than the original, so my guess is that ill have a better shot at mpeg-4, any suggestions?

MPEG-4 is a container AND a video standard. The container, mp4, can hold basically any video type and any audio. An example is AAC audio and XviD video.

The standard, MPEG-4, is anything, such as XviD or DivX.

Well, did some research and kinda figured that out, the thing is, some time ago i downloaded from here a video which was actually in mpeg4 extention, or something like that, but thanks, that clears things up, guess i have no choice but to try to get it in actual mov format @_@

<a href="http://www.m4if.org/mpeg4/?PHPSESSID=98 ... b1">mpeg-4 FAQ's</a> it is an AVI standard ^^ to Primiere.

yes ^_^
MOV's are like AVI's - they are RAW footage and what you are looking for is
something to help shrink that footage; right?

CODEC's that have worked the best for me have been Divx 5.0.5 and MP4.

CODEC's that have not worked ( that is to say . . I can't get them to work right )
are Xvid and MPeg1 T_T - yeah, MPeg1 gives me a hard time!!!!

The best way to find-out what is best for you is to have a one minute clip and
see which one of the CODEC's works and looks best for you ^^
--here's the catch, set hte Bit Rate at around 1123 or 2250 and see what they look like.

Part 2 - the Audio Question

Hit Doom9.net or is it org now ! ??? T_T

anyway, there are many way's of getting Primiere to encode MP3 and MP4 Audio
via your RENDERing/Export Options and Doom9 has a very good selection ^_^

I do not like Lame, but most people sware it is the best ^^

MPEG-4 is not AVI standard, MPEG-4 is TOTALLY different from AVI. AVI is just a container.

AVI is a container, once again. It can hold any type of footage. Raw footage would be the footage with no container. Which is not (AFAIK) possible. MOV (Quicktime) is also a container. It can hold compressed data (Sorenson) or uncompressed data (Uncompressed YUY).

MP4 is not a codec, it's a container. What you put in that container is up to you. DivX sucks. XviD rules, and MPEG-1 is not a codec (or is it?)

MPEG-4 isn't hard to encode into. For example, I followed Everwicked's Guide to MPEG-4 for encoding XviD and AAC and placing them into MP4. I personally used a filtered through AVISynth version of my HuffYUV master-NES video, encoded it to XviD with no audio in Virtualdub, and then used aacenc to encode the audio to AAC. Then I used MP4UI to mux it into MP4.

oh god, both of you shut up

Mpeg 4 in it's most abstract application is a standard that defines video and audio compression and transport. It acts as a specification for building totally independent encoders and decoders so that anything you encode as part of the standard can be read by any other compatible part of the standard. Mpeg 4 (and 2) does this by issuing profiles and levels based on it's decoding complexity and field use.

The ONLY video codec supported by the standard mpeg 4 container is Mpeg-4. Any profile, any level. Most people without knowing it are using Advanced Simple Profile Level 5, hopefully (but not necessarily) within the standard's restrictions. It doesn't matter if you created the mpeg-4 video stream with XviD, DivX 5, DivX 4, 3ivX, PenisX, Sorenson, Mpegable, Dicas, WME8, whatever, any more than it matters whether you used TMPGEnc or FFMPEG or CCE or Procoder or whatever to create an Mpeg 1 video. Reguardless of the container format, avi, wmv, mp4v, raw, it's still an mpeg 4 video stream that can be decoded by an mpeg 4 compliant decoder. So long as you can read the format, you can decode it.

The audio codecs supported by the standard are (mp2?), mp3, aac, and a bunch of speech-like synthetic audio codecs. AAC plays the largest role.

To make it compliant with the standard, you have to follow the standard to the letter. You can't put whatever in the container like with matroska. If you could, matroska wouldn't be here. You can, however, put the right video and audio in under the right circumstances and be guaranteed 100% that in the near future it'll be able to be played back practically anywhere.

To clean up some other stuff laying around, of course raw video is possible, and Mpeg-1 is a codec when taken in the context of the Mpeg-1 video encoding spec.
For the rest of the confusion/questions, you have to be able to grasp the scope and concept of a standard like mpeg 4, especially vs the obfuscated bunch of crap we've had in the last few years with vfw mpeg 4 'codecs'.

AAC audio is great. I have been playing around with it and got great results
