    Problem with PNG files

    Hi All,

    I have a bit of an issue with PNG files causing the movie meter at the bottom of the presets programming window to go a little wild. My designer originally created some still images at 2048x2048 resolution and this caused the movies meter to freeze at 590%.

    Possibly coincidentally, catalyst has been crashing whilst editing a preset containing this file. (the mouse continues to move about but button presses and keyboard strokes do not work) I've tried converting the files to AIC 1024 x 768 (possibly unwisely) and its dropped the meter down to 30% but that still seems high for a still image.

    Is there an issue with png files of this resolution or is there a more efficient file format i could be using?

    System setup:

    Mac Pro 8 x 2.8GHz
    4GB RAM
    X1900
    128GB SSD
    CatalystPM 4.10 m165UB HD

    Thanks in advance

    UPDATE:

    The mac has crashed on me 6 or 7 times today which is quite worrying. I've done some tests and looked into the file format and it seems that the origial file is 1628x1732 in 300dpi PNG format. i guess this would cause such a tax in the system compared to the 346x264 at 72dpi of the 'Testing PNG' file in library 000. If i have the 300dpi file in layer 1 and then load a movie into another layer then the meter drops to 13%. Can anyone fill me in on what this meter represents and why it would vary so drastically.

    huw
