Avidemux supports mp4 and mov files now...

[Kurtnoise]

I don't know if this is has been mentioned before (if yes delete this thread) but now the last Avidemux builds support mp4 and mov files as input.

For those who don't know what Avidemux is : this is mainly a free editor for AVI, MPEG files + mp4 & mov files now. There are a bunch of video/Audio filters included to edit your files. So, check out the website : http://avidemux.berlios.de/index.html


There are certainly some bugs but this is a great stuff...

doesnt seem to support .mp4 output?

[Kurtnoise]

nope but there is MPEG-1/MPEG-2. I think it's planned...

[Doom9]

give it mp4 output and there'll be a stampede of people coming their way

[SadaraX]

The mp4 support is only in the SVN/CVS versions. When then 2.2.x branch of the SVN is finished and put out to release version, Avidemux will officially support mp4.

Right now Avidemux can read mp4/mov very well, though not perfectly yet. Output of mp4 is about half done, I think XviD+AAC work good, but h264 has not been finished yet.

If anyone would like to try Avidemux from the latest SVN, there are wiki docs (I maintain about half of them myself) about compiling it yourself, though its relatively straightforward.

You can give this one a try, though I don't know to what level the support was finished at that time.

thx but i already found that one, doesnt support mp4 output

any idea how to contact the avidemux guys best? is there an irc channel?

[Drachir]

Avidemux use FFmpeg for MP4 muxing with all his bugs, AFAIK.

Muxing based at libGPAC would be nice. But MEAN (developer from Avidemux) mentioned there isn't much documentation, how to use the lib.

Support for Timed Text could be interesting. Avidemux come with a tool to extract VOB sub and convert it to SRT.

I don't know any other tool beside MP4Box that convert SRT to Timed Text.

hm maybe he knows ffmpeg and is able to add the ctts creation with b-frames to it?

Best way to contact Mean and anyone else who can help is at the Avidemux forums. http://www.avidemux.org/pun/
There is not IRC channel that I know of.

What is Timed Text? I do not know anything about it. Though I am helping to write more features for the SRT subtitles. In the long run, with diligence, I am hoping to write quite a few nice features for it. But right now I am about half-way done with an auto-correction option for OCR reading errors.

mpeg-4 timed text is the only official subtitle format ever defined by mpeg

basically there is no spec for how ttxt should look like in "text form", so there are two forms of how to do this:
1) .ttxt developed by the gpac project (handled by mp4box)
2) texml developed by apple (handled by mp4box and quicktime)

imho .ttxt from gpac is much nicer for personal editing and authoring a ttxt stream than apples texml.
strictly speaking it also doesnt matter what you use, cause in the end the stream will be the same when being placed in .mp4

Any plans to output matroska? A search of the website yielded no info.

No one but myself and J.M. have discussed it. I am hoping to get the format added with multi-audio-tracks and soft subtitles. There was a push to get OGM more supported with these features, but the consensus seems to be that after mp4 is more or less finished that MKV is the next task.

Of course, I have not discussed any of this with Mean, so its only between myself and a little bit with J.M.

I hope it comes to pass. I can't wait. Actually I can, I've been waiting for Gabest to update his matroska muxer for ~1.5years, so I can wait for MKV output from avidemux.

SadaraX, can you maybe make a win32 compile for avidemux 2.2 latest svn? mean doesnt seem to be able to atm and i know nothing about compiling

or anyone else?

if latest avidemux svn really supports mp4 editing and mp4 output this tool would be the first freely available, virtualdub-like, mp4 editor

[bond]

moved,

btw celtic_druid you have pm

[celtic_druid]

Yeah, I saw it earlier. Had a go, lots of errors, fixed a few, but I don't have time to work on it more. Might be a job more suited to those who have compiled previous win32 releases.

[bond]

split and merged

hm i will point the dev of avidemux here, maybe he can give you a hint on what needs to be taken care of?

sadarax also pointed to a doc:
