Editing Theora files

[DaveQB]

Searching didnt find what i was after.

I am loving Theora, the quality improvmenet over my previously frequently used codec, lavcodec is great!

Speed is a bit slow right now, but eh! for the quality/size reduction, its great.

But the problem i have now, is once i have encoded my files up with ffmpeg2theora i cant find a visual editor to edit the files, like cut parts out and then direct stream copy the audio and video.

Even MEncoder refuses to mess with these theora files
MEncoder 1.0pre7-3.4.3

ic you are a mkv fan, maybe its a solution to remux to mkv, edit, and then remux to ogg

also if you are able to find out where a keyframe is its maybe possible to cut ogg with a hexeditor? just a wild and maybe totally wrong guess

Oh so the problem is the container not the codec ??

I'd like to use a GUI editor to visually see where i am cutting.

Only have avidemux2 2.0.40

Maybe the new 2.1 has Theora support. It has OGM support already.

[Dont want to upgrade right yet, in the middle of a big project with loads of avidemux project files, dont want them to break]

Has anyone a better idea on this now ? I still can't find a way besides dumping to another format.

I know Theora is young, but hoping there is a way (I would imagine there would be a great demand for this)

vdubmod 1.5.10.x should be able to do this, it has .ogm support (but I've never really known wether .ogm and .ogg are the same container format or not. I think .ogm was just .ogg but renamed to differentiate audio-only files and audio+video files).

Avidemux has much more recent builds, same goes for mplayer/mencoder :)

mplayer/mencoder : http://esby.free.fr/CelticDruid/mirror/mplayer/
avidemux : latest full revision (http://fixounet.free.fr/avidemux/win32/avidemux_r2440.zip) and latest update revision (http://fixounet.free.fr/avidemux/win32/r2569.zip, unzip on top of the full version)
However the latest "official" release is here : http://fixounet.free.fr/avidemux/download.html ;)

Edit: since avidemux doesn't need to be installed, it'll be fine if you unzip it in another directory for this specific purpose :)

ogm and ogg are the same for vorbis audio, but not for theora video

I think VirtualDubMod only runs on Win32, and I havent got that :)

I just tried Avidemux again, no go. Ver 2.1.2

I know MPlayer can play it and MEncoder can encode it to another format, but I want to edit it, timeline cut parts out and direct copy save it.

This what I am complaining about already a long time. There is a poor support for end users by Xiph.org. I think your only hope is that Avidemux will add support for Ogg. I'm also hoping for MKV support in Avidemux.
