I had the same issue with AVCHD footage. To fix it, I installed the ffdshow package.
I hope it works for you, but my personal experience with FFDShow was ugly. It caused so many problems that I needed to do a complete reformat and reinstall of OS and programs. I know opinions differ on this, but this was my personal experience and let's hope you will not have the same.
I've got Premiere CS4. Could earlier successfully import MPG videos from my camera to Premiere CS4 without problems.
Now suddenly it doesn't work - "file dimensions (width/height) too large".
I am using the same camera, same size of video as before, Nothing is different, but it just doesn't work anymore.
anyone that can help??
i'd be very very thankful!!
I'm on a mac by the way, just been 2 months since I bought the program....
