hi andrew,
thank you for your reply and the detailes screenshots.
i checked all the footage again: and i only used 8-bit DNxHD 25fps@1080p and corresponding the BM driver.
strange is the sometimes the BM did not really respond and stayed @23,98 fps - after several times the BM stayed the the right frame rate.
but the "stuttering " issue is still there and appears unregularry and not understandable…
it only affects the video display via the BM card - the audio recording is without any dropouts…
at the moment i downgraded to N7 - and there are no problems at all! ;o((
so i checked also chipset compatibilty (intel Z270) - there should be no problems.
so in my opinion there is something happening with the new video engine in N8?
cheers,
jochen
