Question 1

Do I need to install anything to use Rampify?

Accepted Answer

No. Rampify runs entirely in your browser using WebAssembly. ffmpeg.wasm handles video encoding in a Web Worker, and AI interpolation runs via ONNX Runtime Web. No downloads, no plugins, no native apps.

Question 2

Does my video get uploaded to a server?

Accepted Answer

No. All video processing happens locally in your browser. Your footage never leaves your machine. The only server calls are for authentication and subscription management.

Question 3

What video formats does Rampify support?

Accepted Answer

Any format ffmpeg supports — MP4, WebM, MOV, MKV, AVI, and more. Export supports MP4 (H.264) and WebM (VP9) up to 4K resolution on Pro.

Question 4

How does the AI slow motion work?

Accepted Answer

Rampify uses RIFE (Real-time Intermediate Flow Estimation), a neural network that generates intermediate frames between existing ones. This creates smooth slow motion without judder. It runs on GPU via WebGL when available, with CPU fallback.

Question 5

Can I cancel my Rampify subscription anytime?

Accepted Answer

Yes, and there's no retention flow or cancellation questionnaire. Open the account menu and choose Manage subscription to reach our billing partner's customer portal, where you confirm the cancellation. Your Pro access continues until the end of your billing period, then you drop to the free plan.
