Will denoising blur the video?

Crisp balances noise removal against detail. Keep the Denoise slider lower to preserve texture, or push it toward Max clean for very grainy footage. Because it's AI restoration rather than a simple blur, it removes noise while rebuilding detail.

Can I remove noise from a video for free and without a watermark?

Yes. Crisp's Enhance lane — including denoise and low-light cleanup — is in the free tier and never watermarks your export. Everything runs offline on your Mac.

Does it work on low-light and night footage?

Yes — the Low-light preset is tuned for dark, grainy phone and night footage, cleaning noise while lifting detail. For very damaged clips, the optional generative Max-quality lane goes further.

How to remove noise & grain from a video on a Mac

The short version

Open Crisp

Grab the free Crisp app for Mac and open it. Everything runs on your Mac — nothing is uploaded.
Drop in your grainy clip

Drag your noisy or low-light video onto the window. Crisp reads it automatically.
Pick Low-light or raise Denoise

For dark, grainy footage choose the Low-light preset. Want manual control? Open Advanced and slide Denoise toward Max clean for heavy grain, or keep it low to preserve fine detail.
Export

Crisp denoises and restores the clip on-device — and upscales it in the same pass — then saves a clean new file beside your original, watermark-free.

Denoise vs a plain blur

A simple blur hides noise by smearing everything, softening the whole frame. Crisp uses AI restoration — it removes grain while rebuilding edges and texture, so the result looks clean and sharp rather than mushy. Dial the Denoise slider to trade a little detail for a lot of cleanup, or vice-versa.

Noise, grain, low-light — one pass

Problem	What to use
Dark / night / low-light grain	Low-light preset
General sensor noise or compression speckle	Enhance + Denoise slider
Old, badly damaged footage	Max quality (generative restore)
Noisy AND low-res	Enhance upscales + denoises in one pass, up to 4K
