When you try to import Sony ILCE-7R 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.

“I have a ton of AVCHD .mts files taken with Sony ILCE-7R. I know I can start editing in Premiere without transcoding. Unfortunately, my machine doesn’t have enough power to handle them. Would it be better to transcode to a different format for easier editing in Premiere? If so, which format is suitable? And which program is good to do this? Please kindly suggest a solution if you know. Thanks in advance.”

Transcoding Sony ILCE-7R AVCHD .mts files to ProRes or DNxHD format will be easier to edit in Adobe Premiere. Video Converter performs good at doing this.
