What is mp3 video?

I have some lecture files in mp3 format? but surprisingly it is video filles and play nicely with real player but can not open in windows media player.


I never heard about mp3 video. How a file with .mp3 extension plays video with audio.





Any body know what is mp3 video and how to convert it other format?





I am not taking about mp3 audio only. this mp3 has audio and video slides.








Thank you

There is no such thing as an MP3 video. MP3, which stands for MPEG Audio Layer 3, is an encoding standard for audio files. More than likely, the file name extension is incorrect. Try examining the file in AviCodec to identify what format the file is actually in.

The audio portion of the file may be encoded in MP3 format, but the video will be something else.





edit(3/29) : The MP3 format does not support video encoding which is why I'm saying that the file name extension is incorrect. To find out how to convert the file to another format, you need to know what video codec was used to create the video portion of the file. If you download and install the program in the link provided, you can find out what video codec was used. Once you know what video codec was used, then I can tell you how to convert it to another format compatible with WMP.
