no luck in preventing the expression to break with the code below.

value = colors[sliderValue];

if (sliderValue > colors.length)
value = [0/255,0/255,0/255,1]
if (sliderValue < 0)
value = [0/255,0/255,0/255,1]

Oh.. You are right. Thanks. There was a “)” too many in the code as well. Updated below in case someone wants to use it.

However, this expression is very picky and breaks if the sliderValue goes out of range.

Is there a way to prevent that?

colors = [[0/255,0/255,0/255,255/255],[128255,128/255,129/255,255/255],[114/255,25/222,26/255,255/255],[12/255,62/255,0/255,255/255]]; //etc...
sliderValue = Math.floor(comp("mainComp").layer("COLOR_ADJUSTMENT").effect("Slider Control")("Slider"));
value = colors[sliderValue];

Thanks Dan. Finally, I think the penny dropped on how to move about in the timeline with frame accuracy.

var myComp = app.project.activeItem;
var t = myComp.frameDuration;
var myLayer = app.project.item(3).layer("Black Solid 1");
myComp.time = myLayer.startTime;
var goTo = parseFloat(prompt("Go to frame"));
myComp.time = myComp.frameDuration*goTo;
alert(myComp.time);

Thanks for the fast replies.

One solution I have figured out is to create all reference keyframes in ie the first 100 frames of the composition. (Render will then start at frame 101).

If I create new keyframes on the neighbouring frame by clicking the “diamond” for all layers, I can then drag all these new keyframes to the desired position. However, if it is a lenghty composition, navigating back and forth is still time consuming. The neighbouring frame are also in most cases an inbetween.

I will dig into the scripting solution.
