Hello, I just signed up here because I need help with this.
I am using iMovie HD on a Mac, and have discovered the slow motion feature sucks. I downloaded JES Deinterlacer so I could get a smooth slow mo, and it works very well. The only problem... it takes FOREVER. I am trying to get a 2 second video clip to be in slow motion, but iMovie says it has "underlying media" which was trimmed from the original clip.
How can I get rid of this "underlying media", so that my slow mo processing can go faster?
Or is there a complete simple alternative to getting smooth slow motion clips?
