    I am filming with Panasonic DVX 100AE (16:9 pal DV and import my staff with firewire, export to DVD via encore cs5 High quality). Lately I have a strange problem, playing my videos in television screen beteween 14 inc and 30 inc, video quality is very good
    but when i tried to see the same video in 37inc or bigger television screen I saw a low quality video about -10% or -15%. I have a little blurness, a kind of little flicker specially when camera travveling along the set and small dim squares appears in the image. These dim squares are viewed very well on the people face.
    I think this is low video quality problem.
    How can i fix my video, i want only 15% to improve.

    regards Nick

    Too low a bitrate? Post a sample so we can evaluate it.

    Sorry my friend but i dont know how to post a sample. Anyway I think something doing when i try to convert dv avi (from premiere cs5 finshing the editing) to mpeg2, trying to make a file so to send to the encore for burning.
    I tried microsoft avi and mpeg 2 many versions but the video quality is medium.
    Do you know the best codec for encoding via media encoder to create high quality Dvd?
    for example h.264, mepg 2, uncompressed e.t.c

    thanks Nikos

    The best quality always results when you do the fewest conversions.

    Either convert your original footage straight to DVD, or, if you're doing
    editing and need to render out the result, use lossless or similar.

    I agree with you, I need o lossles codec.
    However the media encoder has many codecs, do you know which of those are losless?
    I have tried mpeg2-dvd, mpeg2, microsoft avi and the quality is unpropriate (low or medium).
    Suprisly, yesterday, I tried H.264 and I think this codec work
    very well and the quality seems excellent, Today i 'll test the video
    quality in 37inc television set. I think uncompressed microsofr avi
    is very good also.

    I have checked video quality on 37inc tv. The quality is E X C E L L E N T !!!!!
    I Think H.264 codec is the solution.
    Any other suggestions?
    best wishes

    If it works for you that's great. Often it's a case of trying a few things
    to see the result.

    I'm still not clear what you're actually doing. Are you:
    render > H.264 > mpeg-2 (DVD) ?
    Or are you viewing the H.264 on the TV directly ?

    I render the timeline via media encoder to H.264 (i am doing my simple adjustment
    depending what I want to do) and then I import the file in to encore and the
    work done.
    Importing assets with dynamic link has the exactly same result and quality
    and then build and burn the dvd.
