Why in god's name won't my mp4 import?

[Volksy]

Hey all,

I'm a bit stumped and after googling literally everything I could think of, trying different codec packs, trying different singular codecs, and manually changing the FileIO .dll plugins, I'm stumped. I have some x264 mp4's I want to import, and Vegas is being a poop and saying "Video: Stream attributes could not be determined." WHY? D:

Current setup:
Sony Vegas 7.0e
ffdshow installed
K-Lite Standard installed
QuickTime 7.6.2 installed
Current plugin Vegas is using to pull mp4s: qt7plug.dll (it provides an audio stream but gives the above error message for video)

Sorry for the doublepost, I can't seem to find the "edit" button on my original post...

I also have haali media splitter, lagarith, utvideo, and a couple other codecs installed, but I wasn't sure if they're relevant as they mainly pertain to audio and .avi files

Thanks again!

I don't think Sony Vegas 7.0 can import .mp4 files. I believe 8.0 is when the program started to accept such format, so anything 8.0+ would allow you to import mp4.

No, I'm pretty sure it does. My friend has 7 and imports mp4s all the time ;-;

Nevermind, worked with a friend on the issue, ended up having to remux. Thanks though!
