And an expression to modify the duration of a text layer?

[Luis Palencia]

Oh thank you very much.

Is there any expression that allows adjust the duration of a composition?

What I want to do is change the duration of many composition, each composition has a layer text, I want to change the duration of composition as long as the length of the text.

For example:

Composition1
Text: “Hello, Word”
Duration of Composition1 = 5 seconds (for example)

Composition2
Text: “Hello, Word. The sky is blue and the children play in the park”
Duration of Composition2 = 15 seconds (for example)

I want to calculate the length of the text with “text.sourcetext.length” and that multiplicate for 1 second and the result apply to the duration of that composition.

Can you help me t_t ???
