Hi, @PaperCrane …
I’ve just been doing a complex edit with all sorts of speed changes, compound clips and effects … and started to really get hit by the stutters.
So - whilst I’d used Optimized Media before, I needed to understand it better this time, and dug a little deeper.
And, what I hadn’t realised was that just setting the additional project settings doesn’t actually create optimized media … you need to tell it which clips (normal or compound) to optimize, and then it keeps updating the optimized media for any editing changes.
And - WOW - what a difference!
I probably didn’t need to go as far, but set the size to 1/8 … still more than adequate detail for editing … and soooooooooooo smoooooooooooth!
When you select the clips in the Media Pool, right click and select “Generate Optimized Media” … and it then goes off and creates it.
Perhaps you did all that - in which case I’ve not managed to help … but it’s certainly something I’ll be using a little more in future.
