Building a slate with Expressions

[Dan Ebberts]

I think the name will be like this:

comp(“precomp”).layer(1).source.name;

and the number of frames like this:

s = comp(“precomp”).layer(1).source;
Math.round(s.duration/s.frameDuration);

Assuming your footage comp is named ‘ftg’ and the footage is the only layer inside that comp, you can access that layer’s properties using the following code:


var getFtg = comp("ftg").layer(1);


You can then do getFtg.whatever to get the data that you need. For instance:


//get the layer Name
var theName = getFtg.name;

//duration of layer (secs)
var getDurSecs = getFtg.source.duration;

//duration of layer (frames)
var getDurFrames = getFtg.source.duration * getFtg.source.frameDuration;

//frame rate of ftg
var getFrameRate = 1/getFtg.source.frameDuration


Once you have the info you want, you can combine them into a string. You can use the characters “\r\n” to force a line break if you’d like:


"Footage Name: " + theName + "\r\n" +
"Footage FrameCount: " + getDurFrames + "\r\n" +
"Footage Frame Rate: " + getFrameRate + "fps" + "\r\n";


Hope this is what you were looking for. Good luck!
