raw mp4 vide + wav -> mp4

[kwanbis]

Hi, i have some raw mp4 videos, and wavs, and i want to merge all the raw videos, plus the wavs, to make a high quality mp4 video with audio. The raw video and the wavs, are extracted from ASF files created by my Panasonic's D-Snap SV-AV25. I use videolan and asf tools to extract the raw video, and the wav files. The SV-AV25 creates one ASF file each time i press record, so after a shooting session, i end up, for example, with:

video1.asf, video2.asf, video3.asf

after using videolan, and asf tools, i end up with:

video1.m4v, video2.m4v, video3.m4v

and

video1.wav, video2.wav, video3.wav

and i want to do

(video1.m4v + video1.wav ) + (video2.m4v + video2.wav) + (video3.m4v + video3.wav) = bigvideo.mp4

IIRC, we can't mux wav files with raw videos m4v into mp4 container...btw, if you want to keep the "high-quality" as you notice, you can try to transcode your wav files in alac (this is a lossless format) with iTunes. Thus, you can mux easily your video and audio streams into mp4.

i actually was thinking on encoding the WAVs to something first, aac, or mp3, or anything else.

encode the .wav to aac (no matter if as .aac or .mp4) and mux with mp4box with the following commandline:

MP4Box -cat video1.m4v -cat video2.m4v -cat video3.m4v -cat audio1.mp4 -cat audio2.mp4 -cat audio3.mp4 output.mp4

make sure to use the latest version of mp4box

So are you guys saying it is possible to mux elementary .m4v streams with MP4Box?


Cheers
