    We are viewing it on a Samsung full hd lcd tv. And the player is Sony Blu-ray player(BDP-S300).

    Progressive source content encoded to progressive MPEG-2 and displayed on a progressive display should look great.

    There must be something wrong with your settings and/or workflow somewhere along the way. You need to make sure every setting in each application is set to progressive or non-interlaced.

    What frame rate is the 720p?
    What frame rate is the MPEG-2 set to?

    720: 50 and dvd: 25..

    The link you gave me:
    It’s looking like Moire. “Both the moire and jaggies are clues that video mode deinterlacing is taking place instead of film mode.”

    How do you change this?

    You got yourself a can of worms there.

    Unless you are doing a proper conform from 50-25fps, you are simply throwing away half of your frames, so no wonder progressive looks ‘Choppy’

    There are ways to properly conform your footage but I don’t know of a way using the tools you have there. Personally I’d use Cinematools on the Mac (Part of Final Cut Studio) but you probably don’t want to hear that.

    With some knowledge of scripting you can get good results using Avisynth:

    hehe.. i’m beginning to think this is way over my head.. 😀
    we have a scripting guru here our company, so I look into the avisynth method! Thanks for all the help so far! 🙂

    I don’t know much about blue ray players, but we were having the same problem once…turned out our dvd player’s progressive mode was turned off…

    What was the option for turning it on? (e.g Progressive on/off?, or something completely different?)

  • Cole Prine

    Yeah it was just progressive on/off. It was just buried in the menu options.

    One of my players has a physical switch at the back, but I really don’t think this is the issue here.
