Audio / video playback offset

When I import a video, I always have an offset (about 6frames) when I playback.

I tried many formats, after reading this :[productfamily]=1

On stop, it’s sync, but while playing the video TC and project TC and not sync.

Does anyone have this issue ? maybe more infos about codex or format we should use ?

Config :
