ClipCompat Lab

Reproducible test cases with known inputs.

Each case uses a tiny synthetic media file generated for testing. Download the same sample, run it through ClipCompat, and compare the result with the documented expectation.

Five starting fixtures

From a safe baseline to target-dependent codec cases.

The cases are deliberately small. They test the rule engine and content workflow, not visual quality or editor performance.

Case 01Supported

H.264 CFR MP4 Baseline

A small synthetic MP4 that represents a conventional H.264 editing baseline.

Case 02Editing Risk

H.264 Variable Frame Rate Editing Risk

Synthetic H.264 MP4 with irregular frame timing to test VFR detection and verdict priority.

Case 03Conditional

HEVC 10-bit 4:2:2 Conditional Workflow

A synthetic HEVC source that exercises environment-dependent bit-depth and chroma rules.

Case 04Test Required

VP9 WebM Import Test

A synthetic VP9-in-WebM file that tests a less universal editing path.

Case 05Target-dependent

AV1 MKV Target-dependent Compatibility

A synthetic AV1-in-MKV source that intentionally produces different target guidance.

Why these exist

Development evidence should be inspectable.

These cases document a known input, the media facts it was designed to expose, the expected rule behavior and the safe troubleshooting advice. Each downloadable fixture can be identified by its published SHA-256 checksum.

  1. 1
    Download a fixture

    The files are generated test patterns with synthetic audio.

  2. 2
    Run the relevant checker

    Use the same browser-local analyzer as any other file.

  3. 3
    Compare the verdict

    The case explains which result is expected and why.

  4. 4
    Keep limitations visible

    A rule-engine test is not a guarantee of editor performance on every machine.
