Smooth speed ramps: How are you doing them?
« on: February 13, 2025, 11:52:24 AM »
Remember how some old 411s would have slo mo clips with extremely smooth deacceleration and the audio would also pitch down accordingly with the slo mo? Any tips on how to accomplish this? Not really a fan of the abrupt speed ramps, the gradually speed change is far superior. How are y'all accomplishing this with today's NLE options? Turns out Cool Edit Pro can do the audio trick.

I still use good old after effects to do ramps but I believe you can do it in premiere as well. either way it's basically time remapping with in/out keyframes and making sure to ease in/out of the slow mo portion

I use FCPX and if you select the part of the clip you want slow mo with the range tool (R) and change the speed it will automatically apply a speed ramp, you can drag the ramp out or in depending how long you want it to ramp into slow mo. once you do that, and you go into the same tool to slow down the clip and at the bottom it has a setting for "preserve pitch" which you'll want to turn off. this will give you the ramp slow mo w the epic audio.
Probably are better more precise ways of doing this technique but this method works for my needs

This is how I’ve done them for years now and it’s ideal. I do miss the after effects way though where you could choose the steepness of the ramp slow mo and get that nice pitch shifting sound.
