AE script for Premiere subtitles
Hi,
I found a script online that reads the metadata of an audio file (which was previously analysed by Premiere) and extracts the text from it, placing it into an empty text holder in After Effects at the exact time that the text should be appearing. It displays line-by-line with a maximum of 10 words at a time. It’s a very smart little script and works well.
I’ve contacted the author to ask for help from him, but thought i’d post here too.
I’m looking for a way to modify the script slightly so that when extracting text from the metadata and displaying it on-screen, it detects when there is a full stop (ie. end of the sentence) and then saves it for a new line, when it is time for that to be shown. If no full stop is found, then it continues to display a max. of 10 words to fill the line.
Thanks in advance,
Sean.L = thisComp.layer("posetivity_voice_1.aac");
max = 10; // number of words to display
n = 0
if (L.marker.numKeys > 0){
n = L.marker.nearestKey(time).index;
if (L.marker.key(n).time > time){
n--;
}
}
s = " ";
if (n > 0){
base = Math.floor((n-1)/max)*max + 1;
for (i = base; i < base + max; i++){
if (i <= L.marker.numKeys){
s += L.marker.key(i).comment + " ";
}
}
}

How would it recognize a full stop?

Thanks for the reply… Forgive my ignorance, but surely when searching through the text metadata in-which the full stops reside the specific character could be identified? Unfortunately i’m not a code pro so can’t do more than just think of such an argument logically, like an if then else type statement.

What gets passed from Premiere to AE comes in as markers, with each transcribed word in a separate marker comment. That’s really all the information there is, except the marker timing info.

Ah ok. Thanks Dan.
Is there anyway of editing that metadata directly? Because working with the text in Premiere is limiting.
Appreciate the help – thanks.

I would say it’s likely. AE scripting has access to the XMP JavaScript library, so I would think you’d be able to access the audio file’s metadata, edit it, and save it. I haven’t tried that specifically, but it seems like it should work.

Thanks Dan,
I’ll have to bookmark this project until i have time to fiddle with it. For the moment it seems easier to just inset subtitles manually, where i’ll have full control.
Appreciate the help.
Sean.
