After Effects – Timewarp Effect Workflow to Create Quality Slow Motion Video

Open After Effects and import the files to apply the timewarp effect
Next we have to Interpret Footage Right click on the imported clip and choose >Interpret Footage Can only do one clip at a time
On the "Interpret Footage" menu, near the bottom is a section called "Other Options" to loop the footage. Loop 2x for 50%, 4x for 25% etc. Either way, you'll need to extend the duration of the Comp Settings to fit the new length (i.e. double for 50%).
Make your composition by dragging your footage down and drop it on to the "New Composition" icon Drag multiple clips if needed to the composition icon to make new compositions
Select a composition and Apply the Timewarp effect on the clip loaded in the composition
Adjust the Speed to desired value: (our example 40.00) % Tuning: Set Vector Detail to the 50 to 60 value if you have lots of render time otherwise leave it at 20 Set the Filtering to Extreme if you have render time otherwise leave at normal Motion Blur found that it can help but can make footage look weird so use with caution
>Composition> Composition Settings
Note the Preset will match your clips resolution But we need to change the timeline Duration here to be as long as we looped the clip in the previous step. Ex Looped 2 x's make the timeline at least twice as long Add an extra couple of minutes just to make sure you can extend your clip enough to show the entire clip.
You will also need to drag the end of the clip to the end of the composition
Click back on the Project tab
When you have your effect set correctly in the Effect Control tab
