Why this exists

“MP4” is only the container.

Premiere has to decode the stream inside the file. H.264, HEVC, AV1, VP9, frame-rate mode, bit depth, chroma and the decoding environment can all change the result. ClipCompat reads those facts first, then separates documented support from conditions that still need a real editor test.

H.264 / AVCHighlights common MP4/MOV baselines and Adobe's documented MP4 hardware-decoding path.
HEVC / H.265Calls out 10-bit 4:2:2 as hardware-dependent instead of promising a universal pass.
VFRFlags variable timing as an editing/proxy risk even when the codec itself is common.
AV1 / VP9Uses a cautious test-required state until a stable rule can be verified for the selected workflow.

Safe workflow

Diagnose before you transcode.

Adobe's own troubleshooting for audio-only imports tells users to inspect the actual source codec and format. ClipCompat automates that first diagnostic step but does not overwrite or convert your file.

  1. 1
    Analyze the original

    Read the media facts locally.

  2. 2
    Review the evidence

    Separate media facts, official support and heuristic risk.

  3. 3
    Test the original

    Do not transcode a working source just because the codec is unfamiliar.

  4. 4
    Create an edit copy only if needed

    Keep the original source unchanged.
