Hello!
I need to convert a Xvid-coded moviefile to .mov, but I can´t open the Xvid file in Quicktime.
Can I somewhere download a plugin for Quicktime?
Do you know about a free Xvid to avi/mov converter?
Thank you very very much! |

Are you on an Apple or Windows machine? I'm a Windows person so I'll try and help from that end...
I haven't worked with QT, but on a Windows machine, it would be unusual to me if you could play a video and not be able to open it.
Also, are you trying to re-encode the file or just move it from the AVI container to the QT one?

xvid is a video compression similar to to Divx and is not a 'normal' avi that can be easily edited.
Googling XVID to MOV I found a few utilities that may help you out:
//www.riverpast.com/en/support/tutorials/convert/xvid/mov.php
//www.google.com/search?hl=en&lr=&safe=off&q=XVID+to+MOV
I have not tried this conversion myself.

That's not correct at all. AVI and QT are both container formats. They are independent of the codec that the material they contain is encoded in. For example you could have mpeg 1 encoded material inside of an AVI file, or xvid encoded material in a QT file.
The question here bogulo is do you need to transcode? That is, do you need to change the compression method that the video is compressed in.
Not needing a recompress should be much easier(and also not introduce re-compression quality degeneration which a transcode to a different compression would do unless you transcode to a lossless codec) since the goal is just to change the container. If you need to transcode, then things get trickier.
If you don't care about the possible recompression quality problems, you MIGHT be able to transcode the xvid avi into a lossless compression AVI(huffyuv would probably be the best choice here) and with any luck, QT might be able to open that(assuming it's having some problem reading the xvid stream.
However, that even seems odd to me, as Apple does have it's own mpeg4 implementation which afaik is distributed with QT. Xvid is just an open source implementation of mpeg4. So QT *should* be able to open it unless something else is broken. You might try installing a build of the xvid codec or ffdshow(although I don't know if QT works with DirectShow filters or now, so ffdshow might not help if it doesn't).
