Clip Slider



  • I've made this patch to continuously slide several video clips across the screen. It works but I wonder if it can be done more simply. Any ideas?

    Nothing attached @ray ?



  • Tried to attach the patch yesterday and I saw it here but now it's not, hmm...
    Am trying again.



  • Can this patch be done more efficiently?

    Hi Ray.
    First, I can't run the patch, since I am on Windows and it includes Mac Core actors, however; I was able to open/view it, and based on what I see I would venture to say that it is setup pretty efficiently.

    Being that you are running movies straight to CI projectors and using the projectors to move the images, that should be about as good as it gets, since the core projector should be most efficient [uses GPU].

    With this setup, there are 2 things I would watch.
    1: how is your video cards GPU handling things.. On my PC I have a desktop widget that shows my GPU clock usage (and all my cpu cores), this way I can instally see how my processor/s are handling the patch. In your case (not knowing your video card) I would want to ensure that you are not maxing out the GPU.
    2: It looks like you might be loading a lot of media. Are your drives fast enough to handle this?? (again I have a widget to watch the data rates)

    Sorry I don't know any Mac tools for this type of system data analysis, but I am sure there must be some great ones available.



  • Hi DusX

    Thanks for checking it out. I'm running it on a Mac Mini i7 16gig. The clips are all 320 x 240 so it runs smoothly but I 'd like to use it with larger resolutions but it gets sluggish. Macs have an Activity Monitor built in the system like the Task Manager in Windows, so I'll check that also.

    Thanks for your help,
    Ray

    For me it looks fine as well, what codec are you using?

  • Photo-jpeg optimized for streaming with the converter from Mark.
    I thought it might be possible to do the same thing with calculators and only 2 generators to push everything along instead of 1 for each clip but couldn't get it to work right.

    I think the benefit would not be that big.
    And it's difficult to do that with just a calculator actor because adding for example 12 does helps until it reaches the value 100 and then stops for 12 numbers to start again at zero. The problem is that the number doesn't get wrapped to start immediately at zero after reaching 100.

  • that's the problem...
    thanks
