Applying effects to layer with the blending set to Screen
Hello, that's what I have now - a video file with encoded subtitles. They are white, the background is black, I can put them easily onto my actual video by simply changing the blending mode to Screen.
The problem is that when I try to add any effect, it's still affecting the WHOLE layer, as though changing blending to Screen didn't matter. I tried making a composition, but even if the layer has its blending selected in the composition, the actual composition still comes with a black background.
Is there a way to "extract" the visible part of a layer (in my case the white text) and make any operations on it? I was simply hoping to add some kind of glow, set it to black to make it stand out better from the background (occasionally there are some white parts so the text is hardly visible).
I still have the subtitles in a .srt file and I know there are other ways (adding the text manually as the actual text layers, trying to get the VLC to encode the text into the actual footage etc) but there are about 100 lines (so the first solution would be pretty tedious) and I wand to add some other effects to the text (so the second solution wouldn't work either - I want to avoid having to deal with many projects and exported files and swapping them around).
Finally, converting the said text video to an uncompressed video MIGHT be an option, but unfortunately I'm kinda running out of space - this file would be ~11GB. Also I'm not sure if the background would really be gone in the exported file.
Do you have any other ideas maybe?
