MP4 editing issue
Good afternoon all!
I’m experiencing the issue where Sony Vegas Pro 9.0 freezes when I try to edit an MP4 file.
I have done a good deal of research on this and none of the fixes have helped my issue. My attempts include:
-Installing the full K-Lite codec pack
-Reinstalling Vegas
-Closing the process in Task Manager that some suggested to try. The process never showed up so I couldn’t close it.I’m confused because I have read conflicting posts on this topic. Some say that Vegas can’t open MP4’s, and others, including my real life friend’s, that say they have no issues whatsoever.
Furthermore, I’m really not interested in converting. I spent a day trying to convert using the suggested Lagarith codec and I only experienced further issues. What are these people doing differently that allows them to edit MP4?
I’m running Windows XP on SP3.
Thanks so much for any further advice!

Vegas Pro 9.0 handles MP4 files just fine. Whoever told you it didn’t doesn’t know what they are talking about.
Installing the K-Lite codec pack is about the worst thing you could do. It can actually cause problem with Vegas, not solve them. NEVER install a codec-pak on a video editing workstation.
I would start by uninstalling Vegas, then uninstall the K-Lite codec pak, and then finally re-install Vegas hoping that it can re-establish all of it’s codecs.
Where did you get these MP4 files from? MPEG4 is a very broad specification. Depending on where it came from Vegas may or may not be able to open them but in general it handles MP4 files fine.

K-Lite can make a mess of your system… not recommended.
Vegas can be pretty sensitive to errors in video files, MP4 included. Vegas 9, for example, will crash on some of the files produced by the Sanyo Xacti FH1. This seems to be due to the FH1’s MP4 files sometimes containing negative timecodes — an illegal situation.
My solution for this wasn’t to render to something else, but “simply” to remux the MP4. A tool like YAMB will do this for you pretty easily. It’s going to take a little time, but depending on your MP4 file’s origins, you may have some compatibility problems.
