Fade translation for text cues from AppleScript

[Ben Glover]

Hello, 

I'm trying to work out the best way to have a text cue appear and with each new cue the text cue is translated -y 100 pixels. Essentially creating a reverse scrolling animation with each cue until the 5th or 6th cue then it fades out.

I was able to create this manually with groups and multiple fade cues but hoping there's a simpler way with AppleScript

Logically I imagine it to be something like this (with 3 cues as an example).

Q1 - Text1

         fade opacity 100 Text1 0.5 seconds

Q2 - Text2

         fade opacity 100 Text2 0.5 seconds

         fade translation Text1 -100 y 0.5 seconds

Q3 - Text3

         fade opacity 100 Text3 0.5 seconds

         fade translation Text1 -200 y and fade down opacity 0.5 seconds

         fade translation Text2 -100 y 0.5 seconds

etc..

Ideally, I will rework the subtitling cookbook example to create groups containing the text cues and fade cues so I can generate these from around 700 lines.

Thank you.

Why not put all the lines in a single text cue and just use relative y translations to scroll the text up a line at a time?
You could use a feathered mask to use a soft edged region anywhere on the display

Or if you want to scroll the text up and fade up the new line then use a relative fade on the y translation of an enclosing group ( as in the attached screen recording)

However I expect what you really want is the example in this attachment, which uses 2 cue lists to allow the overlap of the scrolling and the fading up in place!

You could use a script to autogenerate both cue lists from a text file

If you were using a lot of cues (e.g the 700 you say you want to use) you would probably want a repeating script cue to run once a second  when you start the sequence, that would stop the first active text cue if the number of text cues exceeded the number of text cues visible on the screen.
