Choose a current DNxHD route for Premiere Pro
Premiere Pro can import many MXF formats, but an Avid-origin Op-Atom file may still depend on its codec, folder structure, and accompanying media. Try importing or linking the original media before transcoding.
If Premiere cannot decode the source, create a DNxHD MOV editing copy that retains the project resolution and frame rate. Verify picture, audio channels, timecode, and sync; do not claim that a lossy conversion preserves original quality.
