The Fostex is set to 48/16.
Any clues why? The editing sequence is set to 48/16 as well. Only the sound recorded on the on-board camera stays perfectly in sync.
Of course the on-camera sound remains in sync., it's using the same clock as the pictures.

The Fostex uses a different clock which is very very slightly different and it's drifting slightly.

That's not a problem with semi-pro equipment like this.

If you want good sync. spend a few thousand and get a better camera and a Nagra , AETA or Sound Devices recorder with timecode.
