    Default Film Noir 2.0 - Advice Needed

    Hello,

    I am hoping to use a blue screen for some scenes in my new movie, however I am having problems with unexpected artifacts --I'd appreciate if you guys could take a look and give me some feedback -- the artifacts appear mostly around my ears -- if you have any other suggestions about the use of the effect please let me know,

    I've experimented with progressive vs. interlaced as well as all the blue screen effect parameters in Premiere Pro.
    Thanks,

    Zam

    Sorry I've nothing to offer. I've never seen that sort of artifact before, you appear to be suffering from some sort of vertical striping throughout the whole image.
    Have you zoomed in at all ? This can play havoc with interlacing (except your lines go the wrong way for interlacing issues - unles, of course you filmed with your camera on its side)

    Thanks man -- I didn't clue in that it is actually vertical striping until you mentioned it -- I am now suspecting that the artifacts may be generated in my workflow -- my camera films 720p AVCHD but my editor works with AVI, so I am converting from (AVCHD) MP4 to (Apple DVCPRO NTSC) AVI as the first step.

    You could try some feathering to smooth the edges but if it's as a result of the conversion you need to really address that part of your work flow.

    Thanks guys.

    I tried a number of different strategies:
    - zoom vs no zoom
    - different cameras (GoPro, Sony, Canon)
    - different capture formats (AVI instead of AVCHD)
    - different software (Pinnacle instead of Premiere Pro)
    - different blue screen
    - green screen instead of blue screen
    - different distances from the screen (very close to very far)
    - different lighting on screen
    - different lighting on myself
    - Nordic runes
    - bocci balls
    - you get the picture

    In all cases, I ended up with the exact SAME vertical artifacts as in the sample video (sometimes worse, but never better than in the sample). As it turns out, my video club offers a two-day green screen course so I think I'm going to sign up and bring all my footage (I now have several GB of footage in various formats).

    I hope the video club can get to the bottom of this mystery.
