realistic performance expectations


    Feb 17 2011 | 12:12 pm
    The question is - how realistic is what I am trying to do ?
    I am trying to crossfade jpegs, at the minute 1500 x 1000 pixels. The snag has been getting xfade fed a smooth stream of numbers so that the crossfades are smooth and flawless. About 90% of the time they are but then, whatever method of generating the numbers for xfade that I use - cpuclock or line, the rest of the time the numbers choke and there is a hiccup in the crossfade.
    I imagine this is due to processing power v image size. Ideally I want the image no smaller than my screen, 1440 wide. My processor is a 2.5 GHZ core 2 duo.
    Is this unrealistic ? If so might I succeed with a faster machine. Like a 3.2 GHz intel core i3 processor, or a mac pro 2.8 GHz quad core ? What would realistic expectations be to achieve a 100% of the time flawless xfade ?
    Thanks,
    Jem

      Don't know if [bline] would help, has worked for me before when [line] has choked things.

      I've just been testing with some 2400x600 jpg's and patch below and haven't seen the problem you mentioned yet. I'm on a MBP 2.66Ghz Intel Core 2 Duo.

      Thanks Luke, bline I had no greater luck with but I will study your patch.
      Cheers

      There's an alternate strategy for fading between still images, using only one jit.qt.movie. It should be more efficient:

      Totally OT: How do you create the piece of code that you write here and use for "New from clipboard"?
