How is Scroller Data Recorded?

So I've been wondering about this for a while now, and I've never really had a chance to experiment when I have scrollers in the rig to figure this out. What data exactly is recorded when dealing with scrollers? If I set a scroller to [Color] [13] and record a cue, is it recording Frame 5 of whatever size scroll you have, that specific color, or just the DMX value for that particular frame on that particular scroll? What if I set it using [Color] [3] / [161] (gel picker)? What's recorded then? If I for some reason get new scrolls, will the console recognize this and still go to frame 13, or still go to L161 regardless of frame, or something else?

What about calibration? If I record a couple cues, then realize my calibration is off, will recalibrating after the fact update the raw values in all those cues I've already recorded? Same question for Palettes. I tend to group my Color Palettes by color, so my L161 frame will be CP-161 regardless of whether that's frame 3 or frame 20, then I also have scroll-specific CPs at some higher number. If I go through and create all these references, then go back and calibrate each scroller, will it update? Or is it better for me to just ignore calibration and "calibrate" each scroll directly into my color palettes? On that note, do most people use CPs for scroll frames, or do you just find it easier to record the "F 5 L161" value (from [Color] [5]) directly into cues?

Sorry for all the questions, I'm just curious. Thanks in advance!!

  • Hi Michael!

    First of all, you should type [Scroller] [13] to set a scroller to frame 13.
    Otherwise you get problems if you have scrollers with color-speed or fan-speed.

    [Color] [13] sets the value "13" to all color parameters of the device, even color-speed and fan-speed.

    Recording

    As I see it, the behavior is like this:

    The console records the frame number in cues, color-palettes or presets. If you change the roll later, your scrollers bring the stored frame with the wrong color.

    If you store the color in palettes or presets, the cuelist will record the number of the palette or preset. If you overwrite the palette by another one, the cuelist will get the information stored in the nower palette.
    Example: your Color Lee 201 is stored in CP 201. Rosco 79 in stored in CP79. You copy CP 79 to CP 201, your device will show Rosco 79 coming from color-palette 201

    factory colors

    If you store [Scroller] [3] / [161], you reference a global color-palette, in this example Color 161 from Lee. The Console will look at your string, if there is a 161 from Lee. If not, it will show a color witch comes alike.
    So, if you change your scrolls with 161 on another place, your device will show the right color

    Another way to get a simular behavior could be to record color palettes not with frame-numbers, but with hue / saturation -  values.
    The disadvantage of both procedures is, that you do not have control of frame numbers, if you need an open move from one color into another one...

    callibration

    In my opinion callibration should be done at the service. It is a tool to come far with a show, if the scroller does not work correctly, but I never would callibrate my scrollers by default

    Color-Palettes or not

    Our plays do not use that much colors, Most times only 3 to five different in one show. I like to see the used colors and presets  of a channel by just selecting it.
    Therefore I record the used colorpalettes side by side
