    Hi I have huge problem (from week ago)

    I work in Premiere CS5 (DV and HDV)

    I make scenes with 60-50% of speed and
    When i render or even make a preview in premiere my clip looks really bad, has flashing areas.
    Youtube sample of problem

    My station:
    Motherboard. ASRock P67 Extreme 4
    Proc. Intel core i7 2600 3.4GHz LGA1155
    RAM. DDR3 CL9: 12GB
    HDD. WD WD10EARS 1TB Caviar 64MB Sata
    Cooler Aerocool 700W
    GFX. Asus Geforce GTX 460 1024MB DDR5
    Win7 x64 Home Premium

    I have quick time and K lite codec pack (newest)
    I’ve checked this on radeon card but still films flashing

    I’m going to change Motherboard on Gigabyte but don’t know it’s gonna help.

    Any Ideas ?

    I think you are seeing artifact that you can’t catch in real time.

    You could try enabling frame belending and se if that helps.

    A better option would be a plugin like Twixtor which creates tweening frames.

    I think what you are seeing the the effect of a 60% rate from an interlaced source video file.

    Try doing it at 50% and see the difference.

    Frame blending won’t really help too much here i think.

    That’s a field refresh issue.

    Try a 50% speed, with blending (60-65 are bad numbers.) Alternatively, use Twixtor in AE.

    Last (and worst choice) is try a deinterlace.

    Best,
