How to Use Remove Grain from Video
- Drop your grainy video onto the tool
- Pick a strength — Medium suits most low-light phone footage
- Enable the temporal pass if the grain visibly dances between frames
- Click Process and download the clean video
Features
- Removes low-light grain, high-ISO sensor noise, and compression speckle
- Three strengths — Light keeps maximum detail, Strong rescues night footage
- Temporal pass targets grain that shimmers frame-to-frame
- Optional edge re-sharpening keeps the result crisp
- Denoised footage also compresses smaller — grain is expensive to encode
Frequently Asked Questions
- What causes grain in video?
- Light starvation, mostly: in dim scenes the camera amplifies the sensor signal (high ISO/gain), which amplifies random readout noise into visible speckle. Small phone sensors are especially prone. Re-compressed uploads add blocky compression grain on top — both types respond well to denoising.
- Can grain be removed without blurring the video?
- Largely, yes — the denoiser smooths random variation while detecting and preserving real edges. Heavy grain needs stronger settings which trade some fine texture; use the lowest strength that cleans your footage and enable Re-sharpen Edges to recover crispness.
- Is this grain remover free?
- Processing and the preview are free. Downloading the finished video is free on any plan, and free accounts get 2 downloads a day for clips up to 30 seconds.
