Hello,
My name’s Josh this is my first post here so I’m sorry in replying to this thread instead of starting a new is the incorrect tactic but I am having this exact same issue & was confused by the number of posts as to how to fix it. I have tried reinstalling the codec that did not work & I know that a system restore might but it’d be a total guess as to how far back to take vista (Ultimate 32 bit) as I don’t know the exact date the problem began so if anyone knows a way to fix this issue without one that would be great. Here is my problem in full if that helps any.
I’ve been having this problem for about 3-4 weeks now my Sony Vegas 9.0 Platinum Edition b won’t read. mp4 files. At first I just thought it was because my trial version was about to expire and it was having issues which was fine since I love the program and was going to buy it anyway. However since getting my Pro Pack from Amazon.com it has continued. I just checked to make sure my Quicktime player software is updated and it is. Can anyone please help me get Vegas to read.mp4 again. When I first had the trial version it read.mp4 fine but now it has just stopped. My raw footage from my Flip Ultra HD camcorder shoots in .mp4 so if I have to convert my files each time before being able to edit it’s going to start eating up my time and become very annoying. Below is a print screen of the error message I keep seeing. Thank you in advance for your help.
