 Premiere to Resolve XML Converter
 
 Processes Adobe Premiere Pro XML exports to make them compatible with DaVinci Resolve on Linux.
-Updates file paths and optionally converts MP4 files to MOV format.
+Updates file paths and optionally converts MP4 files to MOV by re-encoding to Resolve-friendly
+codecs (ProRes 422 HQ, DNxHD, or H.264 in MOV). Stream copy is not used so Resolve can read
