Why Slo-Mo Perfect

Not a filter. Actual new frames.

Most slow-motion tools just stretch time and blur. Slo-Mo Perfect generates real in-between frames using AI.

🧠

AI Frame Interpolation

RIFE technology analyses motion between frames and synthesises new ones — so 30fps phone footage becomes silky-smooth 120fps slo-mo.

FAQ

Common questions

What is RIFE frame interpolation?

RIFE (Real-Time Intermediate Flow Estimation) is an AI model that generates new frames between existing ones. Unlike simple blending, it understands motion and synthesises realistic in-between frames — producing smooth slow motion even from low-frame-rate footage.

Does it need an internet connection?

Only to validate your licence key on first launch (and occasionally after). All AI processing runs 100% locally — your video never leaves your machine.

What video formats does Slo-Mo Perfect support?

Input: MP4, MOV, AVI, MKV, WebM, and GIF. Output: MP4, GIF, WebM, or MOV. If FFmpeg can open it, Slo-Mo Perfect can process it.

What speed factors can I use?

Quick presets for ½×, ¼×, and ⅛× speed are available in one click. The custom field accepts any value down to 0.01× — so you can dial in exactly the cinematic effect you want.

Does it work without a GPU?

Yes. Slo-Mo Perfect runs on both GPU and CPU. GPU acceleration (CUDA on Windows, Metal on Apple Silicon) is significantly faster for long clips, but CPU mode works on any machine.

What is the free tier limit?

The free tier allows 3 conversions per day. Output includes a watermark overlay. Purchase a Creator or Studio licence to remove the watermark and unlock unlimited conversions.

What is Batch mode and who is it for?

Batch mode (Studio Batch plan) lets you queue multiple video files and convert them all in one go — unattended. Drop in 20 clips, set your speed and format, pick an output folder, and walk away. Each file is processed sequentially so resource usage is identical to single-file mode. It's designed for agencies and creators doing high-volume sessions.

Can I use one licence on multiple machines?

Yes — your licence covers personal use on your Mac and Windows machines. The Creator licence includes 1 key; Studio and Studio Batch include 5 keys for teams.
