Has anyone experienced Audion moving out of synch with TMPGENG conversion over a short period of time but then the frame seems to hold for a microsecond whilst the audio catches up. This continues throughout the film and makes it impossible to stretch or resynch the film.

Be interested to know if it has anything to do with PC hardware or TMPGENC settings. Have tested in VDUB Freeze and VDUB for bad frames. Tried all frame rate conversions and extractions etc , etc and always the same.
