  • Possible 5.2.2 Bug

    Posted by John Baum on November 15, 2005 at 4:14 pm

    Just installed the new 5.2.2 drivers and they have fixed the alpha issue the last version had. However I discovered another problem. When I slowed down a portion of a clip it totally screwwed things up. The whole clip shifted about 30% horizontally with the excess wrapping around to the other side. There also seemed to be some major field problems as there were lots of scanline type problems and large color shifts.
    Switching back to 5.1.2 cleared up the problem.

    Hi,

    Can you please post some more details. For example, what application are you slowing down a portion of the clip and how are you achieving this? Do the video problems only occur on the computer screen or also on the broadcast display? It would be great if you could email screenshots or photos of the problem to pcsupport[at]blackmagic-design.com so we can look at your problem.

    Regards,

    Hi,
    I have found it too. I think this happend when the uncompressed (RAW RGB) clip is placed to BM 4:2:2 timeline. The clip apperas black and white then, squeezed horizontaly and one third of it is wrapped again in right side to fill the format.

    Jaromir… try applying a premiere filter like “bightness/contrast” set to zero (null effect) and see it that fixes it.
