Why it exists
“MP4” is rarely enough information to solve an editing problem.
A file can play normally in a media player yet behave differently in an editor. The useful details may be the codec, profile, bit depth, chroma subsampling, frame-rate mode, operating system or editor edition. ClipCompat brings those pieces into one diagnostic workflow before you decide to transcode.
Inspect first
Read the actual source media instead of guessing from the filename extension.
Preserve the source
Do not overwrite a working original simply because its codec is unfamiliar.
Show uncertainty
Use Conditional or Test Required when the file alone cannot prove the outcome.
Make evidence inspectable
Link current guidance to vendor sources and publish reproducible synthetic Lab Cases.
