Convert Audio within a Movie File

[nw]

Hi There,

i have a portable movie player and it will only play MPEG 1,2 + 4 as well as motion jpeg. But the only audio formats it will play are MP3 and WAV.

I have got a bunch of .avi files and i have converted them to MPEG1 and 2 but the audio keeps getting changed to mp2 or aac. Therefore i don't get any sound.

I am currently using ImToo AVI to MPEG convertor. Does anyone know how i can convert the audio within a movie to .wav or .mp3? Are these formats compatible with MPEG?

Thanks very much.

Normally MPEG uses MP2, WAV or AC-3 audio. MP3 audio would be uncommon. WAV is compatible, but generates huge files. It's similar to CD audio. Good quality, but large.

So your best choices may be a MPEG-4 type of file with MP3 audio. If that includes formats like Divx/Xvid, then MP3 would be the usual choice.

There are probably some MPEG encoders that can use MP3 audio, but I haven't tried that combination.

It would help to mention the brand and model of your player. Some of our members may be familiar with it and give better advice.

Thanks for your advice. My player is a Canon M80. It is really a storage device for Pro Photography. It just happens to be able to play a limited number of audio and video formats and has a really nice screen.

Thanks for the device name. Unfortunately, when they list MPEG-4 compatibilty, it can be DivX, Xvid, Nero Digital and 3ivx, Quicktime 6, MPEG-4 AVC/H.264, Nero Digital AVC, Quicktime 7, and next-gen DVD formats like HD DVD and Blu-ray Disc.

But I would try Divx or Xvid first. Both are compact and can use MP3 audio. MJPEG is one other option. It's commonly used on electronic cameras, but usually with WAV audio. Two MJPEG codecs: LEAD MCMP/MJPEG Video Codec or the Morgan MJPEG codec. Or you may find a program that will let you mux a MP3 audio with a MPEG-1 or MPEG-2 video.

There's not a lot of info on the device and it doesn't appear to be available in the US at present.
