Rendering time increased by 6 times when expression layer is switched on
Hello Again,
I am coming from this thread:
https://forums.creativecow.net/thread/227/42339
Here Andrei helped me in making an expression to change the color of the text inside parenthesis in a text box.
However, when I render my project in AME, it takes around 18-20 minutes to render in H.264 1080. When I switch off this layer, it hardly takes 2-3 minutes to render entire composition. Can anyone suggest if this is normal, or is there anyway code can be optimized?Thank You!
var t = text.sourceText;
var splitText = t.split("\r");
var regex = /\(([^)]+)(?=\))/g;function indexMatched(index){
var matched = false;
var match;
while ((match = regex.exec(t)) !== null){
matched |= match.index<index & indexmaxIndex){
maxIndex += splitText[i].length;
i+=1;
}
return i-2;
}indexMatched(textIndex+placeInLines(textIndex)) ? 100 : 0;

You might try converting the expression to keyframes before rendering.

When I do that, it ignores the words outside parenthesis and change the color of entire sentence.

Try rendering in AE’s Render Queue directly and then encode finished video – see if it helps to speed it up.

Expressions are calculated in each frame so they tend to bog down projects. If you must keep it on when rendering try disabling the layer cache and purge every 0 frames in the secret preference menu.
