  • DV50 video displays in upper left corner of monitor, why?

    Posted by Jonathan Bergstrom on July 22, 2005 at 6:40 pm

    I am trying to use the DV50 codec in FCP and display via the Kona2 HD card on a monitor. I can only get it to display moving video in the upper left corner at a reduced resolution. I believe that it has to do with my sequence being set at DV50, while my video out is set at Uncompressed, but according to the Kona manual, this should work:

    “Also like DV25, you can use KONA 2 to convert DV50 projects to uncompressed

    Are you attempting to playout using a 10-bit setting for playback output. Perhaps you should try the 8-bit output and this should go away.

    I have tried both 8bit and 10 bit. 8 bit produces a very pixelated full frame video, that then sharpens to full rez once playback is stopped. I can’t find a setting that allows for full rez playback with the DV codecs (both DV25 and DV50). I know it should, since full frame uncompressed video looks great and plays back perfectly on the monitor.

    An interesting finding as I troubleshoot: The “edit to tape” function plays back the DV50 codec perfectly through the Kona card. No more mini video in the upper left corner. Why would it playback small during timeline playback, but when I go to edit to tape or print to video, it plays back beautiful full screen? Still stuck on timeline playback, any thoughts? By the way, I am using the component outs on the kona.

    Stumped.

    I’m getting perfect DV25 to 8 bit running an erase and install of 10.4.2, QT 7.1, FCP 5.02 Suite, and Kona 1.1.2 drivers. 2 gig machine (rev a).

    What software are you running and on which machine?

    I think this might be a problem with Dynamic RT.

    See if it still happens with the Dynamic RT set to High instead of Dynamic

    hi Jonathan,

    i think setting your realtime effects playback to high
    should fix the problem, used to do the same on the I/O
    box in FCP 4.5 in the past/\.

    The problem seems to have gone away. I have absolutely no idea what i did, other than disconnecting a Digibeta deck and replacing it with a Beta SP deck for a day. I hooked it back up and the problem has vanished. Thanks for your help guys. After your posts concerning features in FCP5, I am thinking that upgrading everything is not a bad idea. (We have tiger, and upgraded all the kona drivers, but we are still running FCP4.5. Perhaps that is the problem.)
