Summary
This review was originally posted on VersionTracker.com.<br />stay away!!!! on intel-macs all your 3ivx encoded films wont play! I have not found any possibility to convert them to any format, that works on intel native! (you can view the fims, if you tell quicktime to run under "rosetta" or use vlc, but cannot convert them. so sooner or later they will be non-playabel)

Summary
This review was originally posted on VersionTracker.com.<br />This codec for Quicktime is todays necessity for most Mac users, without it Quicktime is around about useless at handling any of todays .avi formatted movies. It is also the codec of choice for encoding to a lot of new "movie producers" with good quality output. <b>peterpayne</b> this is not a program/app. but rather an additional codec. I don't know anything about "Mactheripper" (only have a 233 iMac so not into DVD ripping etc.), but I assume it outputs in mpeg in which case you could use Quicktime PRO if you have already purchased that to export it to another format selecting 3ivx as the codec via the options button in the QT dialog box. If you don't have the PRO version of Quicktime you can use a program/application called MPEG Streamclip that is a free download and does much the same thing as Quicktime PRO in the export of .mpegs. If you are still none the wiser the paperwork that comes with the 3ivx download has a link to their website that has some excellent friendly help forums that should be able to assist you.
works very well

This review was originally posted on VersionTracker.com.<br />I think the problems I was having were a conflict with other codecs, specifically the old MS-MPEG4 components. I guess they aren't needed anymore anyway,
