When I used VirtualDubMOD to downsize a huge video with two audio tracks, the result had a sort of flapping background sound. Is there a another program which can SAVE two or more audio tracks, not just READ them like the normal ?? I've tried Avidemux, and maybe I've done something wrong, but that doesn't save the second track either. I can't find any guide as to how set Avidemux VirtualDub or SUPER, so that it SAVES two or more audio tracks... Mod, feel free to move this to a better place, this seemed the correct one to me.
Demux the Audio/video, compress the video and then mux it back. You can do that with Avimux_Gui(if it is an AVI, or MkvMerge). Or you can do that with Handbrake, without demuxing first. It will save the Video with 2 audio traks in an MKV/mp4 container.
Add the video file(you can drag'n' drop it), highlight the file and click "Generate data source from files". Then add the second audio,and click start. http://www.alexander-noe.com/video/amg/en_main_window.html
well, well, i'll be and all that, it does seem to work. Now, if i run it through VdM, it only flaps once per 30 secs or so. IDK WtF that is, The file, muxed via Avi mux gui seems okay, now i'm gonna try it with MP3s instead of the 6 channel AC3's it has now.
update 2: Okay, so there's no flapping sound in the file made by Avi mux gui, so it works. Only thing is, it refuses to be read by AviCodec, but I guess you can't have it all. Next up: burn it to DVD, see if my playa reads it..... had no intention of doing that, where'd you get that???
No, I just mentioned just case you were planning on adding more than one MP3 audio track. Don't know about AviCodec, I use GSpot and MediaInfo.
