Générer un livre avec After Effects

Add subtitles to a text layer with an SRT file into an After Effect project.

If you would to create a srt file you can use the software VisualSubSync.

• Create a text layer in AE and select that layer.
• Select File -> Script -> Run script... from the menu and run the first script.
• In the dialog, select a .SRT subtitle file to import.
• Edit the y position property to 0.
• Paste the second script in the position property.

For Greg

var t = text.sourceText;
t = t.split("!!!").join(":");
t;
