Changing Random Seed of Block Dissolve?

Hey guys,

So I am having to iterate 12 different Full Frame cards for game being played on TV... it's a face reveal game, and for what they want the Block Dissolve is perfect, but it can't be the same order every time.  Is there a way to change the random value?  I'm not finding anything in the settings, but perhaps via expression?

Of course, I could build this out by hand but it should be quite time consuming and not as procedural as I'd ideally prefer.

Thanks

- Willie

    Create your own block dissolve transition.

    one way to do it is:

    use a white solid

    1. Fractal noise (default settings will do just fine)

    2. Threshold (you will be animating this parameter)

    3. Mosaic - set it to "sharp colors" and set your prefered blocked size.

    now you can animate the Threshold effect from 0 to 255 (give and take) and if you want a random seed you can have one in fractal noise under evolution. this white solid will be your Luma matte. place it above your layer and use this as your track matte.

    Brilliant, that's EXACTLY what I need.  Pints on me next time you're in LA.

    Ok - follow up question, everything is great with this, but the speed at which the blocks vanish is kind of all over the place... any way to make it a bit more steady?

    For example, say I want a block to vanish exactly every 15 frames (0.5 sec at 30fps)...

    Thanks
