CS3 is making my m2t files audio go out of sync upon import
I’m using a Focus enhancements DR-HD100 to record in 720p 59.94 in m2t file format. After importing the clips into CS3 the video and audio is sometimes out of sync by 7-12 frames. It seems to happen with varied lengths of projects and there is no way to tell exactly when the video will go out of sync with the video.
After speaking with Techs at Focus I have run a couple tests and I don’t think that anything is wrong with my DR-HD100s. I can play the same m2t clips that are out of sync in Premiere Pro CS3 in Power DVD and they play back fine. No issues with sync. It appears that Premiere Pro is doing something with the clips upon import that is messing with the sync. I am using matrox hardware as well which is why I can edit m2ts.
Any Ideas?

m2t files are supported by premiere, no matter what hardware you have.
Does the audio go out of sync over time?? The longer the clip the more out of sync?
What are the project settings, specifically the frame rate?
What type of camera are you shooting with? (I have a DR-HD100 with a JVC-GYHD110U and had audio sync issues when putting 24p files in a 30p project)Tim Robinson

The longer the clip the more out of sync?Yes it seems to get worse as the clips progress. Sometimes it happens after recording for 1-2 hours.
Project settings are:
Matrox HD>
720p>
59.94 fps>
HDV>
we are using the same frame rate that we shoot in.We are filming with a JVC GY-HD 250U.
any ideas?

What about the audio format… projects and clips?

I have confirmed that the recording audio format is at 48khz the same as the project. I have done some additional testing with focus and have determined that the clips are not actually out of sync but that CS3 does something to the M2ts upon import. Apparently this is not a problem in CS4 according to some people at Matrox video tech support.
I have already bought the upgrade but am in the middle of a very important project and will not install it until the project is completed.
