Every editor publishes a supported formats page. Almost nobody reads it until something breaks the night before a deadline.
- MKV import: several big editors still refuse it outright. - HEVC/H.265: works, but sometimes needs specific versions or hardware acceleration. - ProRes on Windows: its own saga. - RAW video: a different universe of support.
Before you commit, search the format list for your camera's exact codec. Five minutes of checking beats five hours of converting. Screenshot the row and keep it with your project notes. And keep a converter installed anyway, because some file will surprise you. It always does. For the opposite direction, turning hours of footage into short clips, ReelCut handles it end to end for $4.99 a video.
