    Hello Everyone,
    I downloaded a .m2v film from an agency that we have to broadcast.
    When I play it in windows media player it looks fine.

    but when I try to render the film in After Effects, Premiere or Media Encoder, it has strange green artifacting at 1 place in the film for about a second or so. Its always the same place, and exactly the same is each software. Like this…

    Can anyone tell me what is causing this, and what can I do about it?

    Thanks in advance
    Simon

    What operating system and what exact version numbers for the Adobe applications?

    Hi Todd,
    OS is Win 7 pro, Adobe CC 2014.1 (I just updated yesterday). I seem to remember I had this same problem a few years ago. Could it have something to do with the .m2v format?

    thx
    Simon
