fxNP Retime 1.5After Effects
Slow motionnobody shot.
AI in-between frames for slow motion, speed ramps and frame-rate conversion. RIFE runs on your Mac, down to 1 % speed.
What it does
OUT 00:00:00:00Set the speed and NP Retime makes the frames that were never shot.
A 25 fps clip can play at 10 % and still move smoothly, without the stutter of repeated frames or the ghosting of frame blending.
Speed is keyframable, so a ramp is two keyframes. Or key Source Frame for exact time remapping; a fixed value is a freeze frame. Motion Blur samples a real shutter across the source frames, so fast ramps get honest blur.
It watches for the usual traps: scene cuts are found and never morphed into each other, repeated frames from pulldown are skipped, and the clip’s first and last frames hold instead of fading out.
How it works
OUT 00:00:00:00Pick the moment
Speed (counted from the layer’s in point) or Source Frame says which moment to show.
AI in-betweens
RIFE 4.25 runs once per pair of real frames, on your Mac.
Smooth paths
Motion Paths › Smooth Curves moves every point along one path through the neighbouring frames: no wobble, no pop at the real frames, about 10–40 ms per in-between.
Guard
Artifact Guard softens what the model is unsure about. Quality High and Best average extra passes.
Key controls
OUT 00:00:00:00The real parameter names, as they appear in Effect Controls.
- Timing
- Speed or Source Frame.
- Speed
- Keyframable; ramps integrate it from the layer’s in point.
- Source Frame Rate
- 0 uses the footage’s own rate, so 60p in a 30 fps comp uses every real frame.
- Engine
- RIFE (AI), Optical Flow (Vision), Frame Blend or Nearest Frame.
- Quality
- Draft, Normal, High (about 1.8× the time) or Best (about 3.5×).
- Motion Blur · Blur Samples
- 100 % is a 360° shutter; spreads over several frames on fast ramps.
- Motion Paths
- Smooth Curves, Straight or Per Frame (1.4).
- Artifact Guard
- Softens areas the AI is unsure about.
- Scene Cuts
- Continue Motion, Hold Last Frame or Interpolate (Off).
- Duplicate Frames
- Skip (Auto Cadence), Skip (Original Timing) or Keep.
- Speed Anchor
- Count from the Layer In Point or the Layer Start.
- AI Resolution
- Half, Full or Auto.
Very fast, unpredictable motion (a swinging net, a spinning roulette wheel) can show errors in the in-betweens.
