Good Decompression Tool?

[aamir12345678]

Is there a good tool that can decompress my Mpeg4 videos to uncompressed [.avi]? Yes, I know the file size will be huge. That's what I want.

I believe virtualdub could do this by full stream processing audio & video then save avi, but can I ask why? what is it your trying to do?

[aamir12345678]

I am going to say why in the advanced conversion forum. The post is TMPGEnc Crash When Doing VBR, or something like that.

If I uncompress it, will it be truly uncompressed [.avi], or will it retain some kind of id, header or tag that will identify it as an Mpeg4?

Try using the decompressor included with avi2vcd, it's excellent, I have used it for years to decompress vbr Divx/Xvid for use in Tmpgenc.

The avi2vcd decompressor can decompress the audio only. The avi2vcd.exe file only encodes.

I've tried VirtualDubMod, but it leaves tons of artifacts. Is there a better uncompressing tool?

Ok, I think VirtualDub wasn't causing any artifact problems. Looks like I was pressing the Preview Input button to view it, and that caused it to show it like it had tons of artifacts. It looked like the picture had lost a significant amount of its detail.

And, as far as the good decompression tools go, VirtualDub does it fine. Do you have to buy Quicktime Pro to use Apple's None codec?
