    Hi Folks

    Sometimes, when I compress Quick Time Movies to Mpeg with the Compression Master(4.0) , It creates a green vertical line on the movie, that only appears on Windows Media Player, on quick time player it goes well.

    Any suggestion?

    thanx for your help

    Sounds like an issue with whatever WMP is using to decode the MPEG-2. (As Windows relies on 3rd party software to do the job.)
    If you can’t see it in Quicktime then I’d assume it’s not a problem with the video file itself.

    Have you tried VLC?

    Actually It is MPEG1 and my biggest problem is that this files are for “normal” people, that kind of user that doesn’t even know the difference between a MPEG or a QT File. So it’s hard to say this people to use something different from WMP. 🙁

    Cheers

    Sorry I assumed it was MPEG-2, It’s rare to see an MPEG-1 these days.

    What I was trying to say was that if you can’t see the green line using Quicktime and you can see it with Windows media player, try and see if you can see it using VLC.
    If you can’t see it using VLC then it’s a problem with that particular Windows Media Player and as such all the ‘normal’ people are unlikely to see the green line.

    Are you using/testing both Mac and PC?

    So, this problem only happens on PCs in Mac it went fine. And I tried with two or three PCs. I think that is a problem with this version of wmp.

    I dont know if it’s any of my compression master’s settings that cause this.

    What frame size are you using for the MPEG?
