Adding an animated watermark on a video I'm trying to add an animated logo watermark made of looping image sequence on a 1080p video using alpha over node in the compositor, but the rendering is 2-3 seconds for each frame and that can take a lot of time for long videos. Is there another method to do that to increase the processing speed?
After doing some tests I found out that Video Sequence Editor gives 5-10 times faster result than the Compositor.

I added a Transform Strip to the Logo image sequence, changed Blend to Alpha Over and adjusted Position and Uniform Scale, then duplicated both Logo and Transform strips to match the video length.
