When you try to import Sony 7K 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.

Adobe Premiere Pro comes with native support for Sony 7K AVCHD (MTS) files. To be able to work with Sony 7K AVCHD footage in Premiere correctly, you need to copy the ENTIRE folder from the camera to your video hard drive and import from there. If you only have bare .MTS clips without the AVCHD folder structure, you will get stuck. If that’s the case, you will need to convert the Sony 7K MTS clips first. Check out a quick guide on how to re-encode Sony 7K MTS video for use in Adobe Premiere without a glitch.
