Ctrl+J bring up madvr on screen information. Don't know about TrueHD though.

Thanks for that. On further though I think it may be atmos encoded material that's giving me this issue .I am sure both of the star trek revamps have true hd atmos soundtracks

What am I looking at with the on screen information to see if I am getting perfect audio and.video sync?

You can't measure audio/video synchronization via the rendering stats. You have to do this by eye and ear.

The clock deviation in madVR rendering stats will tell you how far off the video and audio clocks are. But that is not the audio/video sync. It is a measure of audio and video clock deviations, which tend to be in decimals. These are clock deviations that are so slight that a frame needs to be dropped now and then to fix the slight drift. Audio sync has to do with display input lag and the lips not matching the audio.

Try using a fixed audio delay if this is the case: 2033893 (post).
