Hi @RilosVideos - This is an interesting and original use for Shotcut and a demonstration of what can be done with keyframing the SPR filter. Well done for your patience - it paid off!
I think you will be interested in this thread from two years ago:
I’d forgotten about this technique - two years ago I actually tried it out and it worked really well, but it took ages to generate the short demo I made…
One more point - did you intend your text to fade in and out to white, through grey to black? If you want to fade it in and out to transparent, choose “adjust opacity instead of fade with black” in the fade in/out filters panel. If you wanted the grey/black effect, please ignore this!
