    My project properties are HDV 1440 x 1080-50i, deinterlace method = interpolate, adjust source media enabled, GPU acceleration disabled, for eventual delivery as DVD PAL and Bluray.

    This is a Vasst Quadcam multicam project of a stage musical with media from 2 cameras that I have used in a countless number of SVP10 and 11 projects:
    1920 x 1080-50i
    1440 x 1080-50i

    Source footage plays back clearly and cleanly, but in both the rendered files produced using the DVDA template for PAL DVD and Bluray 1440, I am seeing random flickers or jumps in the video at about the speed of a blink of an eye. It’s not a black flicker, and I am not losing audio or video sync, and I cannot hear any jump in the audio. The flickers appear at different points in the rendered files, so it appears to be something Vegas is introducing.

    When I first saw it I thought it was in my disc media (Bluray/DVD-R DL/DVD+R DL, but when I looked at the files being imported into DVDA, I noticed that the issue was already there.

    I have tried using blend fields, but that did not make a difference.

    I don’t know if this Vasst Quadcam issue, or whether other users are experiencing this in Vegass native multicam or single track edits.

    Has anyone using SVP12 noticed this in their output? Any clues as to what I may be doing wrong?

    My system specs: Intel i7 970, 12GB RAM, ASUS P6T, Vegas Pro 11 (x32/x64), Windows 7 x64 Ultimate, Vegas Production Assistant 1.0, VASST Ultimate S Pro 4.1, Neat Video Pro 2.6

    Copied the entire project into SVP11 and rendered it out. Flickering has gone, talk about a crazy workaround!

    At least I can give the client something watchable.

    Spoke too soon. Flicker is still there. It was just occurring somewhere else. It’s even worse. Grrrrrr!
