feature request: Speed

in premiere you can take a slow motion clip and speed it up to 350% for instance using "speed". but if i want to take that RAW slow mo clip into After Effects (and make sure it has the same speed as the sped up clip on my premiere timeline) time remapping doesnt let me choose "speed". So I drag around the time remap keyframes but there's no telling whether I dragged it to change the speed to 350%? 400%? 247%?? There's no solid indicator to tell me what speed I've sped it up to. And there's no exact number to dial in to get the same speed as the sped up clip in premiere (without exporting the clip out of premiere with the speed on it). Can you add the "speed" feature to After Effects?

    "Does this provide what you were looking for?" Unfortunately, it does not.  It's the kind of math that I'll forget in a day.  Not intuitive.  I'm standing by my feature request to add "speed" to After Effects just like Premiere.

    Hi @rachelcenter,

    Thanks for making this post! While Time-Remapping doesn't provide numeric control for the speed of footage, After Effects also has a Time Stretch function that can be set numerically. Right-click the footage layer and go to Time > Time Stretch... to bring up the Time Stretch dialog.

     

     

     

     

     

     

     

     

     

     

    That said, Time Stretch doesn't express the rate of time as speed but as a stretch factor. E.g. rather than 200% being twice as fast, it is half the speed because the clip becomes twice as long.

     

    To set a clip to play at 350% speed directly, you type "100/3.5" into the Stretch Factor field, resulting in 28.57143%. You could also type the desired duration into the New Duration field.

     

    Does this provide what you were looking for?

     

    Cheers,
