View Full Version : Question about AVIMux

I've been making AVI's with GKnot for quite a while, and I have plenty of experience.

I was thinking, after reading about AVIMux_GUI, that it might be better to create my movie using GKnot, and then mux the AVI and AC3 using AVIMux_GUI instead of having GKnot/Nandub do it for me.

Is there any advantages/disadvantages to this?

Also, if I open a movie that already has audio muxed correctly, and I do a straight remux of the audio using AVIMux (ie: without extracting the audio from the avi first), will this give me the advantages that AVIMux gives (such as the reducing of the seeking when playing off a CDROM).

Thanks,
irasnyd

Thanks alexnoe.

I really like the tool. It works well, and I had no problem getting it to work even on the first time.

I also have a question. I tried to reply to this but for a reason it doesn’t load the reply

here it is:

I had a misunderstanding about how avi_mux works. Now I think I understand better. If we have a video V1 and Audio A1 and A2 the way it muxes (sp?) is:

V1 V1 V1 V1 V1 V1 V1 V1
A1 A1 A1 A1 A1 A1 A1 A1
A2 A2 A2 A2 A2 A2 A2 A2

It’s one video stream with 2 audio streams. But what I had in mind and thought that Avi_Mux does was one video stream and 1 audio stream. I thought it concatenates the 2 audio streams into one like this:

V1 V1 V1 V1 V1 V1 V1 V1
A1 A1 A1 A1 A2 A2 A2 A2

However there is one question left for me. If we add a second video, how does it mux it? Is it a second video stream or just concatenated to the first video stream.

2 video sources are not supported (if you intend to concatenate 2 video sources, you have to select both AVI files, "add video source" and will then see only one video source)
