If you know a faster way post it here.
Next week .WMV & .ASF to .AVI

Haven't tried it yet, but what about MP4Cam2AVI:

MP4Cam2AVI is a great app; but
MP4Cam2AVI rencodes the the mp4 audio to mp3.

This takes time , cpu power & gives a very slight quality lost.

Still thanks for the input.

Just select AVI as output format and set audio codec to AAC.

@appsuser

Why would one re encode a video when they can just remux it????

@carbonize

Super is horrible lol...


@Island Boy Thx for the Guide/Links (I dont use mp4 though , although when demuxing I just use http://www.bunkus.org/videotools/mkvtoolnix/

question though why use an AVI container (or mp4 for that matter) when matroska destroys all competition

Super works fine for me but then I only use it to convert avi's for playing on my PSP.

Software compatibility for one; if you're releasing a video you typically want as many people as possible to be able to view it without having to install anything. Then there's hardware compatibility, like DVD players, PSPs, iPods, etc.

Since AVI's so old a standard, you usually find very good support for it. While MKV files are a great format, they're a little obscure still.

MKVToolnix (& it's addons "MKV Extract GUI" & "OGMcleaver v1.0.0") is one of the apps I use most. Love it. (Very usefull with .rmvb "REAL" video files) but like "Queue" said, AVI's is a old a standard & most apps support it.


??? MKVToolnix portable ???? I did not test.

From the website for MP4Cam2AVI:

"By default, MP4Cam2AVI doesn't recompress video, that means no quality loss and fast operation (5-20x realtime, depending on audio settings). Audio can be stored in source format, or converted to MP3 (best for DVD-MPEG4 players) or PCM (best for editing)."

I'm pretty certain that means audio doesn't have to be re-encoded. It's also saying video isn't recompressed. I don't know if that means it's re-encoded or not, or just put in a different (AVI) container...

I agree. I primarily use this tool for extracting subtitle files from .mkv files (my DVD player only plays DivX files, not .mkv...)

appsuser, Your right. I guess I miss that "MP4Cam2AVI" option.

Again, thanks for the input.

Great. I'm looking forward to this...

Because its faster for the user.

Because matroska is a crappy format supported by nothing.
