Adobe Premiere Pro Optical Flow
built-in interpolation for professional results.
- Import your clip into a sequence, right-click → “Speed/Duration”
- Set your “Speed” to desired percentage, check “Time Interpolation” → “Optical Flow”
- Render the segment (Enter) to see smooth in-between frames
- Export via File → Export → Media
DaVinci Resolve Frame Interpolation
high-quality slow-mo using motion estimation.
- Drag your clip into the timeline, right-click → “Change Clip Speed”
- Set “Speed” to your target, tick “Optical Flow” under Retime Process
- Choose “Enhanced Better” for the Retime Engine in the Inspector
- Render on the Deliver page with your preferred codec
Final Cut Pro Optical Flow
macOS-optimized for silky-smooth retiming.
- Select clip, press Cmd + R to show the retime bar
- Click the pop-up menu → “Automatic Speed” → choose “Optical Flow”
- For variable slow-mo: blade segments in the retime bar and adjust each section’s speed
- Click Share → Master File to export
Twixtor Plugin (After Effects / Premiere)
industry standard VFX plugin for frame interpolation.
- Install Twixtor, then apply the “Twixtor” effect to your layer
- Set “Speed” to your desired % and adjust “Motion Sensitivity” for clean edges
- Use mask tools to isolate subjects if ghosting appears
- Export via your host app’s render queue
Slow-Mo Video Editor (Mobile)
Android/iOS app with simple interpolation.

FFmpeg with minterpolate
CLI method for automated frame-doubling.
ffmpeg -i input.mp4 -vf "minterpolate='mi_mode=mci:fps=60'" -r 60 output.mp4
- Adjust
fps=
to twice (or more) original framerate for smoother playback - Use
-preset slow
for better interpolation quality
SVP (SmoothVideo Project)
real-time frame interpolation for any video player.
