    the transparency is something that is a problem

    maybe i just thought a way around it.
    The work around I have used is using a spare mix and layer, set the mix as uppermost and drag it to full screen repeat with the same mix on all outputs and then have black in on the layer and bring it in to act like a inhibit master. The mix needs to have transparent background.
    Sadly on my current shows I am using all layers for most of the show and usually maxing out to 10 odd mixes, so this is not a option.

    With changing the intensity on LED screens I find bringing down the intensity to 80-90% tends to fix the flare issue on camera, but that is more due to the fact LEDs are non linea.
    Colour wise you do start loosing detail, but it is a comprimise that is worth making, in many circumstances, particularly with products like FLED, Mitrix and Spyder where you need to tweak your gamma levels to avoid sparkles, you are already making this comprimise before you reduce your intensity.

    Mix intensities would also be useful for shifting the point of focus from one mix to another whilst still maintaining a built up layer look.... yep transparancies a pain, particulary in multipul layer looks.

    Although the full mix controls via DMX are great I tend to use presets for all of those elements as it saves so much time, compared to dialing on a desk.

    Over the summer, doing so many festivals with TV companies filming, it would be great to have a means of stomping back the intensity, and maintain how all layers work together without having transparency cropping up, and still have the overall normal LED screen setting stay the same for certain key moments. Nothing worse than having far too much LED flare on a well composed image. Plus we never get a chance to line up the screens with racks engineers, on the broadcast trucks, and having the juggling act of starting in daylight and finishing the show in the dark.

    Ok. Phil.

    I played around with this -

    there are 4 colour fx which if you apply them to a black or white layer - on top of everything else in a mix - and scale it up to fill the mix - will dim the output without affecting any transparency

    1. Col fx 87 - black image - layer intensity fades in and out overall intensity
    2. Col fx 87- white image - layer intensity fades in and out
    3. Col fx 88 - white image - layer intensity fades in and out-
    4. Col fx 92 - white image - layer intensity fades in and out

    I have put 4 ways in here - in case i missed something-

    try this

    Cheers Richard.

    I will report back when I get a chance to play with this.

    I tried these. Actually a cool alternative to what I had been doing.

    The simple solution has always been turning up the CMY wheels on my desk in unison until the image turns darker. I use these in combination with ColFX 2 and 3 often as a way to "lighting optimize" dark projection content while busking.

    The show I'm on now however, I had to dial down the content gamma for all the LED content but found I was screwed when I started taking IMAG to the LED. I actually tried a few of these tricks on my last leg and have been able to get some pretty cool colored vignettes of the IMAG over the show content.

    Thtg problems with new beta

    Hi
    I've been using the beta software for bits and pieces and appears very stable, however i have an analogue thtg and it will not drive it for some reason, every time i enable a 3072 x 768 res on catalyst and ask it to go fullscreen it looses the resolution and reverts back to 1024 x 768, running 4.1 with same hardware doesn't have this problem

    try reducing layers and try again.

    3072x768 needs an awful lot of video ram. which video card?

    these decisions dont come from catalyst - they are os resources.
    which are not infinite.

    Check that 'force to resolution xxx at startup' is not selected in monitor section near the top of the catalyst control window..
