Video Audit review
A focused, free browser tool for identifying flashing hazards in video.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
Video Audit is a free, browser-based accessibility testing tool for creators, developers, editors, and accessibility specialists reviewing videos, animations, and screen recordings. Its focus is photosensitive epilepsy risk: the tool analyzes luminance and red-ratio changes and reports potential flashing hazards against WCAG 2.2, Ofcom 2017, Trace24, and NHK/JBA standards. It supports common video formats such as MP4, MOV, and WEBM, while local WebAssembly processing keeps uploaded media in the browser rather than sending it to a server.
Its strongest area is detailed video inspection. Frame-by-frame luminance and red-ratio analysis is paired with sensitivity adjustment and motion-noise reduction controls, helping teams tune the review to the material being assessed. An interactive timeline shows fluctuations across the video, while frame previews mark flash zones. The violations log adds timecodes, violation types, and hazard sizes, and the pass/fail compliance summary gives reviewers a concise result alongside the underlying findings. This combination suits teams that need evidence tied to specific moments in an edit rather than a simple overall warning.
Video Audit is a good fit when the main requirement is checking flashing hazards in video through a free web workflow. Its scope is narrower than a general accessibility testing suite: it is centered on video hazard analysis rather than a wider set of product, document, or website checks. Teams looking for AI-assisted analysis, broader accessibility coverage, or a non-browser platform should consider a different tool. For focused seizure-safety review, however, its standards selection, timeline controls, overlays, and timecoded reporting make the product easy to position in a video-quality process.
Video Audit pros and cons
- Where it wins
- Processes video locally in the browser without uploading media
- Provides frame-level luminance, red-ratio, overlays, and timecodes
- Supports WCAG 2.2 and three broadcast-oriented standards
- Where it doesn't
- Focused on video hazard analysis rather than broad accessibility testing
- Web-only access limits it to browser-based workflows
- No AI-assisted analysis features
