[LEFT]Any changes in real time OHCI ( DV ) preview?. In previous version of Edius it was reported about 2 second - 3 second delay between desktop preview and OHCI preview. If it is not changed may I post in the feature request or known issues section of the forum.

Originally posted by STORMDAVE View PostNot true. FCPs delay is only about 0.1 seconds while Edius is above 0.5 seconds. So it is possible to have a shorter delay.
PPro too is almost real time. But Edius is very annoying for those who edit using OHCI preview.

Just out of curiosity I created a project to see the lag.
On my machine in OHCI mode the delay is exactly 15 frames (0.5 sec.) for NTSC project.
I’m unable to test PAL as my camera will only generate NTSC signal.
Here are the steps to recreate my test:
- Start a new OHCI project.
- Place a black ‘Color Matte’ on the video track and set the length to more then a minute.
- From the ‘Video Filters’ drag and drop onto the black the ‘Strobe / Freeze’ filter.
- Open the setup dialog and set the ‘Interval’ to say 10 frames, ‘Duration’ to 1 frame, the ‘First Half’ to ‘Move’ and ‘Second Half’ to ‘Color Frame’ (default white).
- Without closing the setup dialog, play the timeline (loop playback). If this is your delay (10 frames) then your OHCI and the computer monitors should flash all at the same time. If it is not, then adjust the ‘Interval’ one up (+1) and repeat it until all monitors are flashing at the same time (allow 2 seconds between adjustments for the video to be generated). When both monitors are flashing at the same time your ‘Interval’ is your OHCI delay.
I would be interested to see if the delay changes on different setups…Rob
