THanks this is what I’m looking for. I can now run this trough as an ExtendedScript using aerender.exe, correct.

I have tried one of Dan’s expressions as below:

newDuration = effect("Slider Control")("Slider");
t = linear(time,0,newDuration,0,key(numKeys).time);
valueAtTime(t);

Modified it as follows:

clockStart = parseInt(comp("main").layer(5).text.sourceText.value);

t = linear(time,0,clockStart+1,0,key(1).value+time);
valueAtTime(t);


This seems to be working as what I want on the Time Remap property. It plays the keyframe and continues playing it. But the layer goes black. I can’t seem to see any output. If I remove the expression the layer works fine. And the time remap keyframe works exactly as I want.

This expression holds onto 14secs, which is the first keyframe value. Then when it hits’s clockStart, it continues to play from 14secs. But the output is black. What ami doing wrong here ?

Any updatew on this pls. DAN or someone can help me with this as i have reached a wall on this after multiple tries. Thanks in advance

Here is some updates:

I tried using linear with the script as follows:

clockStart = parseInt(comp("main").layer(5).text.sourceText.value);
clockTime = clockStart-1*(time);

sIn = key(2).time - key(1).time;
sOut = key(4).time - key(3).time;

if (time < clockStart)
linear(time,sIn,key(2).time,key(1).value,key(2).value)
else if (time >clockStart)
{
linear(time,key(3).time,sOut,key(3).value,key(4).value);
}>

I’m using this on the time remap propertery with 4 keyframes. One issue I have here is, if I change the clockStart to some value 14 seconds for example, I need to adjust the keyframe4 manually to get the fadeout properly on the closure, otherwise it does a cut.

Any Other solution to this problem please.

[Mackie John]

Yes great it works fine. Thanks once again.

[Mackie John]

Just another thing, If I have multiple key frames on the same property. How will I target the 2nd key frame. E.g. I have 1 for fade in, another for fade out. How do I target for fade out ?

[Mackie John]

Perfect, I’m grateful to you. It’s working as I wanted, I have understood the logic as well. Thank you so much for you help.

[Mackie John]

I will be feeding clockStart which is just a text layer now externally (outside of aftereffects). So it will come in as in `int`. Right now I have put it a text layer for testing only.

clockStart = parseInt(thisComp.layer(1).text.sourceText.value);
clockTime = Math.max((clockStart-1*(time-inPoint)),0);

[Mackie John]

Yes I understand what you mean, but i’m not getting it. I’m a little weak in expressions and learning them as I go.

I know what I want to achieve but the part I’m missing is how can I calculate how long it has been 0. Can you help with an example, if possible. Will be grateful.

[Mackie John]

Yes, the counter turns zero, after which I want to run the animation (keyframes):

Here, I have thought of two ways. Can you suggest if this is correct or can be improved. FIrst is using valueAtTime, second is using linear:

if (clockTime == 0){
chkTime = time - clockTime;
valueAtTime(chkTime)
}

if (clockTime == 0){
chkTime = time - clockTime;
linear(chkTime , 0, 6, 100, 0)}
