Thread: Screenshot video compression?

    Default Screenshot video compression?

    Hi there-

    I'm a little new to the encoding process and I have a couple of questions if someone could help me out. I am trying to assemble a software demonstration comprised of screen captures (captured with SnapzX Pro), a narration audio track, and PowerPoint Presentation slides.

    The basic issue is that I cannot produce a decent video quality when I export my completed movie. The video quality produced by the component pieces - SnapzX Pro and the PowerPoint Quicktime movie - is very good and I'd like to know why I can't seem to match that quality, one for one, when I export the video after editing it, even if I leave the settings as raw video with no compression.

    I've tried several methods to compile this video, including:
    Final Cut Pro:
    - export PowerPoint slides as images
    - import images into Final Cut Pro
    - add transitions, audio track, do basic editing
    - export, testing many different encoders and settings
    iMovie:
    - export PowerPoint presentation as quicktime movie
    - import movie into iMovieHD
    - add audio track
    - export, testing many different encoders and settings

    I would really appreciate any suggestions as to how I can match the import video quality with the final export quality.

    Thanks so much, folks-
    Jordan

    Vide Reolution is 720 x 576 (pal) & 720 x 480 (ntsc) so when you use a screen capture tool it is probablt capturing at a higher resolution than this. When this is then brought down it looks poor.

    When ever i do screen captures i bring my monitor resolution down from its normal 1152 x 864 to 800 x 600. This gives much better results.
