View Full Version : Crappy conversion - AVI to MPEG with NERO just a bunch of junk!

Howdie,

I have this AVI file I nabbed from somewhere.

I wanted to drop it onto a VCD.

Using NERO, I added the file to the project and after NERO finished the disk (including encode from AVI to MPEG), I viewed the results: crap!

The video was choppy and the a/v sync was WAY off.

Assuming I get a better result by convering the AVI manually, I turned to TMPGEnc; however, it wouldn't accept the file.

I found the guide AVI to VCD / SVCDand found that my frame rate was 20 per second . VirtualDUB did NOT report a VBR MP3 stream. However, I did save the audio to WAV.

Having probs with TMPG, I decided to save the AVI to my HD. I assumed that I didn't want to do any other compression as I didn't want to further degrade the already lousy quality.

I did manage to find the space required by the file but twice now I saved and then opended the AVI only to find it play for a few secs and then report the file invalid. This error occurred when I manually advanced the movie a quarter of the way through.

Ideas?

This looks like gigo.

I suggest that you pay more attention to the sourcematerial in future tries.

VCD is 25fps in Pal or 29.97fps in NTSC, so you need to convert the sourcematerial to this framerate.

A possible way to do this is avisynth, the program is able to insert additional frames at regular intervals. However, adding 5 or 10 frames per second will probably not look smooth in fast scenes and will not be worth the effort. Anyway, you can find support for avisynth on doom9.

Bye,
