High resolution webcameras


    Mar 12 2007 | 6:29 pm
    Hi all.
    Has anyone ever used a high resolution webcam (Greater than 640*480).
    Specifically I'm looking at the DFK 31AF03 from the Imaging Source (1024*768).
    Would this be too much for a mac mini to handle (particularly when
    compositing with an even larger matrix)?
    Any reports on using anything of this nature, particularly regarding
    performance, would be greatly appreciated.
    Thanks.

      Hi Scott,
      i use a DFK 31AF03 (
      http://www.theimagingsource.com/en/products/cameras/firewire_color/dfk31af03/overview/
      )
      on a macmini PPC 1.4Ghz for a long duration (> 1 year) time-lapse
      movie project (so i grab one picture every 30 seconds...);
      when i received this camera, i did some quick test and it seems to
      grab at 15fps or even 30fps, but i don't think you could do any heavy
      compositing with 1024x768 matrix on such a machine (maybe on a
      macmini intel this would be better); the camera is not the problem,
      the cpu is the problem.
      best,

      Thanks for confirming my suspicions Yves.
