Field-syncing problem 1080i @ 59.94 / 60 Hz?
on Nov 18, 2008 at 10:32:51 am

Hi all,

since many weeks we've got the problem described in the subject.

Sometimes when starting the DirectShow-filtergraph the video-fields (interlaced frames) seem to be out of sync. This happens only at 1080i@59,94 Hz (29,97psF) and 1080i@60Hz (30psF) and not everytime, the filtergraph is started.

I've uploaded an image for you to see the effect: http://img291.imageshack.us/my.php?image=errorfm2.jpg

(We connected the DVI-out from another PC to the HDMI-in of our "Decklink HD Extreme 2" and set the resolution to 1080i@60Hz, so the image you see is the XP-default-desktop-image. The error occures also if we connect other devices via HDMI to our capturecard!)

Driver version: 6.7.1.0
Firmware version: ?

Is this problem already known and is there a solution?

Thanks,

- Oliver

Hi all,

just updated to driver version 6.8.3.0, the problem still exists even if it has become better and out-of-sync doesn't happen as often as before.

Thanks,

- Oliver
