Carry out a MediaInfo analysis of the video recorded by the Teradek and look at the analysis Tree view.

In the Video section of the analysis if you see - Frame rate mode   : Variable

that is most likely the issue with the audio sync - most video editors do not handle variable framerate video properly.

If it is variable then you need to run the video through a video converter, eg Handbrake, to get a constant framerate source video and import this into Video Pro X.

If the recording is Constant framerate post the MediaInfo analysis (from the Tree view) so we can see what you are dealing with.

Also include your computer specification and VPX version - see this topic for more details of what is required.

Thanks. You're right, it is variable. Going to run it through Handbrake now. Wondering about the optimal settings for working in VPX. H264, 30fps, constant, ACC, 192?

As far as I'm aware the sound is not affected and should stay in sync.

Thanks John EB. Handbrake converted the video to a constant framerate. VPX editing proceeded without incident. From here on out I'll use Handbrake to convert any Teradek encoded video. Assistance much appreciated.
