Video Compatibility Checker

Check your source before you transcode it.

Drop a video file, choose your editing environment, and get a structured explanation of the media characteristics that may affect import, decode or timeline behavior.

MP4, MOV, MKV, WebM and other formats MediaInfo can read.

Your file is analyzed locally in your browser.

What it checks

Media facts that matter in an editing workflow

ClipCompat reads the actual stream metadata instead of relying on the filename extension. The checker focuses on the attributes that frequently change compatibility or editing behavior.

ContainerMP4, MOV, MKV, WebM and other readable containers
Codec & profileH.264/AVC, HEVC, AV1, VP9 and profile information when reported
Bit depth & chroma8/10-bit and 4:2:0 / 4:2:2 / 4:4:4 characteristics when available
Frame-rate modeConstant versus variable frame rate and reported min/max rates
AudioPrimary audio codec, channels and sampling rate

How it works

The file stays on your device.

The checker uses MediaInfo compiled to WebAssembly. A Web Worker reads the file in chunks through the browser File API, normalizes the reported media properties, then applies conservative compatibility rules for the selected editing environment.

  1. 1
    Select a video

    The browser gives ClipCompat local access only to the file you choose.

  2. 2
    Read metadata in a Worker

    The analyzer reads chunks as needed rather than uploading the video to a server.

  3. 3
    Match verified rules

    Media facts are separated from documented support conditions and heuristic editing risks.

  4. 4
    Show a cautious verdict

    Supported, Conditional, Editing Risk, Unsupported, Known Issue or Test Required.

Why the verdict is useful

The result keeps facts, rules and uncertainty separate.

A generic codec list cannot tell you whether a particular file is VFR, 10-bit 4:2:2, wrapped in an unusual container or being checked for a different editor edition. ClipCompat shows the detected facts first, then the matching rule and its evidence level, so you can see why the verdict changed.

Privacy

Your video is not sent to ClipCompat.

ClipCompat does not upload or store the selected video for analysis, and the checker does not require an account. Media inspection happens in your browser. The checker does not send filenames or extracted media facts to a dedicated application analytics integration.

Limitations

Compatibility is not always a binary answer.

Hardware decoding, GPU drivers, operating-system media components, plug-ins and specific editor versions can affect real-world behavior. ClipCompat therefore uses conditional and test-required states instead of claiming that every file will definitely work or fail.
