How to Convert and Merge AVCHD MTS/M2TS files

Before joining camera clips, compare their resolution, frame rate, scan type, and audio layout. Clips from different Canon, Panasonic, or Sony recording modes may need a common output profile before they can form a clean continuous file. Keep the original card folders until the merged result has been checked across every join.
