Lab Case 05

What this case is designed to prove

Verify that ClipCompat can give different results for the same media facts depending on the selected editing target instead of treating “AV1” as one universal answer.

Expected behavior

What ClipCompat should report

Premiere should remain Test Required because ClipCompat intentionally avoids a broad universal AV1 support claim without stronger version-specific evidence.
DaVinci Resolve should return the supported AV1 decode finding tied to the versioned Blackmagic codec matrix used by the current rule set, while still avoiding performance guarantees for every Resolve 21.x system.
The VFR Checker should treat the fixture as CFR when that label is reported.

Fixture context

What the fixture confirms

This case is intentionally target-dependent. It validates the core product idea that identical media facts can lead to different guidance depending on the editor environment.

Safe handling

A supported codec finding is not a hardware benchmark. Preserve the original and test real playback/editing performance in the intended system.

Observed analyzer evidence

From sample facts to a practical verdict

These synthetic files were analyzed on 2026-10-11 using MediaInfo WASM and the same normalization and compatibility rules used by the checker. This run used Node.js; it was not an import or playback test in Premiere or Resolve.

Image and timing: 8-bit · 4:2:0 · CFR
Premiere / Windows: Test Required
Resolve Free / Windows: Supported

Why Premiere / Windows received this result

AV1 requires a current Premiere test
ClipCompat detected AV1, but the available Adobe evidence used by this rule is not broad enough to claim a universal pass or fail across Premiere versions and containers.
Evidence: heuristic

Next action: Test the original in your installed Premiere version. If it imports audio only or fails, use the detected codec details when troubleshooting.

A readable codec is not a guarantee of editor support. Test Required records a limit of the current rules; Supported is not an editor benchmark. Download raw MediaInfo output, normalized facts, checksums and full findings (JSON). Read the methodology.
