  • loss in imported avi quality

    Posted by Ron Schei on July 26, 2010 at 5:26 am

    Hello,
    First-time poster. My apologies in advance.
    I’ve imported an avi file and created a composition from it. As far as I can tell all of the settings are in line with the initial avi settings, but the quality degrades the moment I add it to the composition. There are screen shots involved, and the text is legible in the original avi file but becomes illegible in the composition.

    The avi is 720×480 (0.91) 29.97 fps
    The composition is NTSC DV, 720×480, D1/DV NTSC (0.91) full quality.
    Any ideas would be greatly appreciated.

    Common causes for that kind of issue:

    [1] The footage isn’t interpreted correctly … right click on it in the project panel, select “interpret footage” and make sure everything in that window is correct (particularly interlaced or non-interlaced).

    [2] There’s a viewing setting wrong that’s making the footage look bad in the comp viewer even though there’s nothing actually wrong … double-check that your comp viewer is set to full resolution (vs. half or quarter) and that the layer resolution is set to full (vs. draft).

    [3] The AVI is in some kind of wonky codec … the AVI format is only a wrapper (like MOV) so AVIs can be made with any one of very many different codecs. If that is the problem, the easiest solution is to transcode the file to a more standard codec.

    It turned out to be problem #3.
    Thanks for the advice!
