When you try to import Sony ILCE-7M2 AVCHD (MTS) files in your project using Premiere Pro, you could get an error message that says, “The file has an unsupported compression type.” This error can be solved via transcoding the footage to a file type that is best suitable for Premiere, such as ProRes for Mac based Premiere, and DNxHD for Windows based Premiere.

“Hello guys, are you having issues importing Sony ILCE-7M2 AVCHD (MTS) files directly to Premiere? I get ‘The file has an unsupported compression type’ message. Is there anything I can do to solve the issue? Any help would be greatly appreciated! Thanks in Advance.”

AVCHD support is native to PPro. Premiere should import Sony ILCE-7M2 AVCHD .MTS clips. But you need to copy the whole file structure of your memory card and then use Premiere’s media browser/import function to properly import them; you can’t drag and drop. If your AVCHD folder structure is lost, you have to convert the Sony ILCE-7M2 MTS files first. The following guide tells the detail.
