specifically mp4 files encoded with nero recode.

thanks

mp4 is a container ;)

What dou you mean with support?

If you want to cut sequences you can use mp4box from GPAC or QuickTime Pro
If you want to extract video to AVI you can use mpeg4iptools, or mp4box
If you want to extract audio to .mp3 or .aac you can use mpeg4iptools or mp4box
If you want to change MP4 container to MKV (Matroska) you can use MKVtoolnix. Now, with mkvmerge (from mkvtoolnix) you can cut video sequences; with mkvextract you can extract only video to raw/AVI and audio to aac/mp3/ac3 ... (or whatever)

thanks for the info jalavera. i will look into those tools.
i was hoping that one of the major video editing apps like premiere pro would have support for the format.

thanks again

mp4box and mpeg4iptools are both command line based apps.
are there any apps that have a GUI frontend???

For mp4box there is YAMB (search in the this forum). For mpeg4iptools there was one MP4IP but is obsolete. So I recommend you to use YAMB.

premiere pro will make you reencode the video i guess.

well, i'm looking for a good tool on processing mp4 file, just like VD/VDM in avi field.

[Jalavera]

There isn't any mp4 (specially AVC) cut-edge tool like VD/VDM in AVI. But YAMB-mp4box is a good choice because if you want to cut an scene it cuts on reference frames before and after your cutting points. If you want to make a frame-accurate cut you can re-encode the first and the last reference frameblock at frame-level and afterwards join first reeencoded block+Smart rendered block 'Direct stream copy'+last reencoded block.
To reeencode the first and the last block you can demux mp4 container to a elementary AVI sequence + elementary audio stream + subtitles if any and make your cuttings manually until frame-level.

Let's say I would like to process MP4 (ASP and AVC video) in VD/VDM. Is there a tool, which will convert it to AVI? I believe that MKVToolnix will mux the video in native format (at least AVC) which VDM can't read. So my only chance is probably to convert it to AVI with all the hacks made to correct "b-frames in AVI" issue. Is there a tool which can do it (both ASP and AVC)? I didn't try it with MP4Box or MKVExtract, I'm just curious in case I would ever need it.

Thanks,
Vlada

There is no one (from my knowledge). But the pass from .avc to .avi to edit with VD is an error if you want to cut at frame-level because AVC-in-AVI is only cuttable (like in MKV or MP4) at reference-frame level (e.g. using SHIFT+RIGHT/LEFT ARROW in VDub is a choice). So it's better to cut MP4 with YAMB-MP4BOX in order to avoid problems in packed bitstreams in AVI.

use avs import plugins for premiere pro.

AVC isn't even fully cuttable at I-frames because references can extend beyond them; only IDR I-frames are guaranteed. It isn't common unless you use lots of references, I believe, but I have no idea how to tell since h264_parse doesn't lay out all the links between frames.

ulead's videostudio supports .mp4 with the mpeg-4 plugin, as i wrote in my sticky
also quicktime does
