Video file analyzer online

A free video file analyzer that reads the real container, codec, profile and level, resolution, frame rate, bitrate, color and HDR metadata, audio and subtitle tracks of any video — and plots its bitrate over time. Everything runs in your browser via WebAssembly and WebCodecs, with an honest platform-readiness verdict for YouTube, Instagram, TikTok and broadcast.

How to analyze a video

1

Drop a video file (MP4, MOV, MKV, WebM, AVI and more) onto the zone above

2

The analyzer reads the metadata and builds the report in your browser

3

Review the codec, color/HDR, bitrate graph and audio tracks

4

Check the platform-readiness verdict and export the report if needed

Check the codec, bitrate, HDR and platform-readiness of any video

What it shows

True container, codec, profile/level, resolution and SAR/DAR — read from the file, not the extension
Bitrate-over-time graph plus GOP / keyframe structure and I/P-frame counts
Color & HDR truth: bit depth, chroma subsampling, primaries/transfer/matrix, HDR10 / HLG / Dolby Vision + mastering display
Every audio track (codec, channels, sample rate, language) with on-demand EBU R128 loudness (LUFS) and true-peak
Platform-readiness verdict for YouTube, Instagram, TikTok, broadcast and HLS/DASH — with the exact fix for each issue
Frame thumbnails and JSON / text / PNG export

Why use our video analyzer

It combines what you used to need three separate desktop tools for — MediaInfo-grade metadata, a Spek-style bitrate view and a platform-readiness checker — in one browser page. Built for video creators, editors, streamers and developers who need to know exactly what a file is before they publish it.

Frequently asked questions

What information does the analyzer show?

The real container and codec (with profile and level), resolution and aspect ratio, frame rate and CFR/VFR mode, bitrate and a bitrate-over-time graph, GOP/keyframe structure, bit depth and chroma subsampling, color primaries/transfer/matrix, HDR format (HDR10/HLG/Dolby Vision) with mastering-display and MaxCLL/MaxFALL, every audio and subtitle track, and a platform-readiness verdict.

How are the files processed?

Analysis runs in your browser. The metadata is read by the MediaInfo library compiled to WebAssembly, the bitrate timeline comes from the file’s own sample tables, and frame thumbnails use the browser’s WebCodecs decoder. No software to install.

Can it tell if a video is ready for YouTube or Instagram?

Yes. The platform-readiness section checks the codec, container, frame rate, aspect ratio and audio against the published specs of YouTube, Instagram, TikTok, broadcast (EBU R128) and HLS/DASH, and flags each issue with a concrete fix.

What is the bitrate-over-time graph for?

It plots how many bits per second each part of the video uses. Spikes reveal complex scenes, a flat line means constant bitrate (CBR), and the keyframe ticks show the GOP structure — useful for spotting under-encoded sections or streaming problems.

Which formats are supported?

MP4, MOV, M4V, MKV, WebM, AVI, MPEG-TS, FLV, WMV, OGV and more. Container/codec metadata is read for all of them; the bitrate graph and frame thumbnails work best with the MP4/MOV family.
