Typical export wait

Exports re-encode the full video in your browser. A 1-minute 1080p clip often takes about 2 to 5 minutes on a typical laptop, sometimes longer on slower devices or with fine grain and color noise. The first export in a tab also loads the conversion engine (often about 10 to 30 seconds).

Frequently asked questions

How do I add film grain to a video online?
Upload a video, pick a grain preset or adjust the sliders, watch the live preview while the clip plays, then click Export with film grain. When processing finishes, download the MP4 or export multiple files as a ZIP.
Is this video film grain tool free?
Yes. It is free with no account, card, watermark, or desktop software required.
Are my videos uploaded to a server?
No. Preview and export run locally in your browser using FFmpeg compiled to WebAssembly. Your source videos are not sent to Vidsembly or any third-party server.
Can I preview film grain before exporting?
Yes. The player shows a live grain overlay while you adjust amount, grain size, and monochrome or color noise. Use Compare original to toggle the unprocessed clip.
What grain settings can I control?
You can set grain amount from 0 to 100%, choose fine, medium, or coarse grain size, and switch between monochrome luma grain and color noise. Presets cover subtle, classic, heavy, and color noise looks.
What video formats are supported?
MP4 and WebM usually work best in modern browsers. MOV, AVI, MKV, M4V, WMV, FLV, OGV, MPEG, MPG, and 3GP files are also accepted when the browser and FFmpeg can read the source codec.
How long does film grain export take?
Export re-encodes the full video in your browser, so wait time depends on clip length and resolution more than file size on disk. A 1-minute 1080p clip often takes about 2 to 5 minutes on a typical laptop. Longer clips, 1080p footage, fine grain, and color noise take longer. The first export in a tab also loads FFmpeg (often about 10 to 30 seconds). There is no progress bar yet, so the status message may stay on Applying grain while encoding runs.

About this tool

Give digital footage a film-like texture

A light grain layer can soften overly clean screen recordings, add mood to b-roll, or help social clips feel less flat. Start with a subtle preset, then raise the amount until the texture matches your project.

Preview grain while the video plays

Scrub through the timeline or play the clip to see how grain moves with motion. Compare against the original at any time so you export only when the look feels right.

Private browser-based processing

Videos often include faces, locations, or unreleased work. This tool processes files on your device, which avoids sending source footage to another service for a simple stylistic effect.

Batch export for multiple clips

Add several videos in one session, tune grain per file, export them together, and download finished MP4s individually or in one ZIP archive.

Typical export wait times

Film grain export is a full re-encode in the browser. A 1-minute clip at 1080p often needs about 2 to 5 minutes on a typical laptop, while the same length at 720p is often faster. Five minutes of 1080p footage might need 10 to 25 minutes or more. Fine grain and color noise settings add processing time. The first export in a tab also downloads and starts FFmpeg, which can add about 10 to 30 seconds before encoding begins.
