OK - a development. I worked out what @RilosVideos meant by his “white screen” method, and I have to concede that it’s a far better method than my Method 1 in the tutorial!!
So I asked @RilosVideos if I can feature this method in my (revised) tutorial, and he kindly agreed - (full credit will be given in the new tutorial), so I’m off to re-do the tutorial. So please bear with me while I catch the time to do it.
In the meantime, here’s @RilosVideos’ method (no commentary). Simple and effective, and you can just copy the white clip and whoosh sound clip to instantly place over further split points. Ingenious!
