Converting MP3 to a dummy video

[kapot]

Hi,

I would like to know if there is an easy way to convert an MP3 to a dummy video?

I mean, a dummy video = video that has 1x1 pixel resolution (visual).

I am not sure about the codec, but at least I want to use it as streaming video. MPEG4?

The main key in this task is that the result must have a video stream! It could be an empty one, a pixel for example.

Anyone know?

Thanks in advance.

You can create a single frame AVI video with the run time of the MP3 file with VirtualDubMod.

1) Use File -> Open Video File. Open a small BMP or JPG file. The file name may have to end with a number like FILE1.BMP. Don't use too small an image many players will crash with very small frames. Stick to 32x32 or so.

2) Select Video -> Frame Rate... Tick Change To [___] Frames Per Second and enter 1/runtime (in seconds) of the MP3 file. For example, if the MP3 file is 120 seconds enter 0.0083.

3) Select Streams -> Stream List. Press Add and select the MP3 file.

4) Select File -> Save As...

Thanks jagabo.

It works, but the frame per second is now detected as 0.02 fps (in my case because I set to 0.0161, total music length = 62 seconds).

Is it possible to resample it? so I can stick the fps to 29.97 ...

If you convert to 29.97 fps you will get a bigger file because the frame will be repeated over and over. You can force the output frame rate to 29.97 using VirtualDubMod:

Open your new AVI file and go to the Frame Rate dialog (or follow the earlier instruction up to and including step 2). In the middle portion tick the "Convert to FPS" box and enter 29.97. Then Save again.

If you used a 32x32 image this will add about 5 MB to the file size. You can use a video codec to compress the video but people will have to have the codec to play the file (or they may hear the audio but get an error dialog about the missing video codec). Some codecs appear on most Windows computers: Cinepack, Intel Indeo, Microsoft Video 1. You might try using a black picture and one of those codecs.
