Good editor for mp4 video files?

I'm interested in working with video in an MP4 container.  I have a few questions.

What can i use to mux tracks together?  Virtualdubmod doesn't seem to support it.

Is it safe to ogg audio in an mp4 container?

Doom9.org has a nice guide about mpeg-4 video/audio muxing.

It is possible, but it is not safe and definitely not a wise idea. MP4 players expect an AAC stream, at most an MP3 stream. Most of them won't play the audio if they find a vorbis stream there.

I suggest you check 3ivx muxer and their guides:http://www.3ivx.com/support/index.html

VirtualdubMod already supports editing of native MPEG4 MKV files, even with AAC audio. The only problem currently is that there is no transmuxer existing as of yet, allowing to put the streams from an MP4 into a MKV file, but Mosu is working on this already.

The reverse, to extract a MKV file after editing into a MP4 could be done already, if the 3ivX guys will cooperate with us and add a nother MEDIASUBTYPE to the allowed input nodes of their MP4 muxer ...... no big deal, we will talk to them after we have the MP4 --> MKV transmuxing working .....

QuickTime does a decent job in editing MPEG-4 files. I know Windows users don't like it, but it works  Since MP4 is based on the QuickTime file format, that's the answer to your MOV-in-MP4 question. However, there aren't many reasons to use MOV on Windows...

What questions ? You are aware i was talking about MKV ( = matroska ), and not MOV ?

Yes, and that wasn't really what I was (trying to) answer. What I meant was that the answer to "Is it safe to ogg audio in an mp4 container?" is that's what MOV is for.

Anyway, if you install 3ivx, QuickTime will happily play advanced streaming profile MP4s, as long as they don't have N-VOP frames (according to 3ivx). I don't know whether they released a QuickTime component for Windows, though.

well thats not an answer 

when muxing xvid or divx5 into .mp4 with 3ivx these files should be 100% spec compliant mp4 files, but qt doesnt handle them (with qpel and b-frames)...

and did you get my mail?

<huge picture>

The only advanced simple profile in 3ivx D4.1 is MPEG Quantisation, the rest have been disabled.

EDIT: Oops, that's a screenshot of Sorensen... silly me...

Actually, he's right

3ivx can decode ASP, but the QuickTime MP4 parser will not parse ASP

Ergo, the decoder can't decode ASP MP4s inside QuickTime.

movs are completely unlimited

i have done it. i encoded a file w/xvid, and B-frames. and QT will play the resultant .mp4 file.

Heh. Same here. I encoded a file with Sorenson + B-frames + Qpel, and QT played it.

ok i now tried it myself with this settings (2 b-frames, qpel) + mp4 container (!) and the latest quicktime doesnt play it

i get a "this file uses technologies quicktime doesnt support" error message
