Not sure what you are asking here. There simply is no fixed temporal period in any of these functions. They are solely determined by whatever you use as the input. Beyond that the normal relation between degrees, radians and Pi apply and trhats what radiansToDegrees etc. are for...

You cannot address masks in expressions and that settles that. Read up on how to copy&paste masks as motion paths. that's al lthat's required.

Bridge must be invoked from within AE using "Browse Presets in Bridge", not launched externally. Only that way the required loopback connection will be established.

Mylenium

Nope. That goes way beyond what any script could do and based on AE's API, there is no way to even write a file IO plug-in that works in this manner, so simply forget the idea....

Expressions cannot access mask or shape layer paths. you can only move layers conventionally this way.

Time is time. I don't really see your problem. If you need to assemble specific strings, then use string methods, for simply converting time to timecode and back use timeToCurrentTimeFormat(), timeTotimecode()etc.

Mylenium

No, there is no such thing.

Mylenium

Isn't it obvious? You are applying 2 transform levels and don't do anything to cater for that. That aside, layer space transforms do not work across comps. They only work inside the same comp. You will have to find other methods.

Mylenium

And your point exactly? All you are telling your layer is to be zero opacity at frame one, but otherwise always 100%. The rest is completely unclear since your description is far too vague to make any sense of it.

Mylenium

Should be simple. Just some quick thoughts:

- determine the ratio of the line traveling speed compared to the duration of the graph curve draw on
- feed the resulting multiplier into a valueAtTime() expression referencing the line for X and the respective Y value from the curve

No. Expressions only reference and modify property stream values, nothing else. They don't care how or why this value is there and what is producing it. Much demanded feature, but so far not come to pass. To update your expressions, use the Copy Expression only command in the Edit menu and then past...

Well is there a way to do the same thing in another way without cluttering up the composition with hundreds of layers? Umm, no. You could of course use any effect that is able to reference another layer and switch the respective selection pop-ups, but regardless of that, the layer being referenced ...
