Unrecognised mpeg file

[gchiu]

I bought a CD-i some twenty years ago ( Andrew Lloyd Webber ) which I haven't been able to play since then as I sold the CD32 MPEG decoder

Finally, I found some software ( isobuster ) that allowed me to pull the dat files off, and I can now play them on my drive using windvd.

But, I would like to burn them to VCD. But VCDeasy says that the file is an unsupported MPEG format being 368x272 PAL.

I added them anyway, and burnt a VCD, but although the sound was largely there, the picture was a complete mess.

I tried tempgenc to try and change it to the recognised formats, but tempgenc also won't read these files.

Ideas??

Edited because I missed the fact that you tried to convert it.

You are obviously aware that it's a framesize (resolution) issue.


Did you try the video file in virtualdub or nandub?

No, I'm a newbie I'm going to look at what these do ...

Okay, I downloaded and tried out virtualdub. It converted my 64Mb MPEG1 file into a 2Gb AVI. *But* the sound stops and starts, and is out of sync with the picture now. And the framerate seems to be slower as well

I guess nandub is next on my list to try...

Nandub was no different .. guess not surprising since it springs from the same code base.

Sound is stacatto, and finishes well before the video does.

Any other options?

Yes nandub is built using the virtualdub source code they are almost the same except for some specific features. There are other variations of virtualdub that still carry the name of vdub.

It's a little difficult to give you a complete lesson on all the features of virtualdub but you can convert the audio, save it to a wave file and using filters you can resize the video to put it in valid vcd spec.

If the audio is lagging or too far ahead because the total time length is different for the audio vs the video,it is possible to make them the same by processing the audio separately using an audio editing prog. This has been discussed previously on the forum so do some searches and I'm sure you will find it.

Read the help files that come with virtualdub.

The reason you ended up with a 2 gig file is because you did not use full processing mode to write the output and use a compression codec for the video and/or audio. This could also explain the out of synch if you used the wrong interleave setting.

Keep experimenting I am sure it will produce the results you want and the output video/audio can be input to tmpgenc to produce a working vcd.
