I have two inputs that are the same image. The first one, I loop to create a video for 8 seconds. I also create two streams that I will overlay. The background is the normal video, and above it is the same video with a LUT (Look-Up Table) that I applied earlier. I make the top video appear as an overlay with a fade-in effect that lasts x seconds before reaching 100%. To create a 'flash' effect, I want to overlay instances of my base image (participant1.jpg) at different very close intervals. The first overlay displays, but not this one "[out][1]overlay=enable='between(t,3.25,3.26)'[outv]", and I can't figure out the reason.
Perhaps because the interval in the between() function is too short. Don't make the interval shorter than 1/framerate.
