Having upgraded to 5.1.1 there is a serious issue with drifting video. Both the output from the Declink studio card and the onboard video show a huge drift in sync. Over a period of 2 minutes the picture drifts ahead by at least 6 frames!
When pressing STOP the video resets and plays in sync for about 10 seconds then begins to drift again. This did not happen in 5.1.0 and we are using the same project which has not had any problems until the update to 5.1.1.
Using the latest Decklink Studio card with the latest 7.95 drivers and firmware. Video is AVI file.
What is going on?
