Published on by Chris King


A simple tutorial that shows you how to easily convert MTS to ProRes, so you can import MTS files to Final Cut Pro for editing with ease.

Q: “I have hours of HD footage acquired on a Sony NEX-FS700. Resulting files are in the .MTS format. Thought MPEG Streamclip could convert them to ProRes for editing in FCP. It doesn't. How can I convert the original .MTS files to ProRes?”

Camcorder has become a part of our life for keeping the memory. It's quite possible that you've shoot some MTS (M2TS) files with your Sony, Canon, Panasonic or other brands of camcorders. Although most of the video editors, i.e. Final Cut Pro has been improved to support MTS, it’s still not a “NATIVE” format. According to Apple, ProRes encoded MOV videos are highly compatible with FCP software. That means you can convert MTS to ProRes so that you can import MTS to Final Cut Pro for editing without any video, audio codec issues.

There are several different transcoding programs, and more than a few MTS to ProRes converting solutions. We combed through the options to pull together the simplest, working method. First of all, download and install Brorsoft MTS/M2TS for Mac (Read the review of 5 best MTS Converter for Mac.

It is generally recognized by videographers as doing a quality conversion. ProRes, in various flavors, is one of the conversion options. It not only can handle AVCHD .mts via importing from camera(with intact structure), but also can convert individual .mts, m2ts files that you’ve get off the camera. A good value. I have used it for hundreds of MTS clips. Just download this Mac converting software and follow the tips to convert camcorder MTS video to ProRes files on Mac (Mavericks).

I used to edit my .mts files with Final Cut Pro without any issues until yesterday on my new Mavericks.
Now I import my .mts file but FCP doesn't recognize the files. Thanks your sharing and let me there's a good workaround to solve the issue. I tried the Brorsoft mts converter you mentioned, perfect output prores files for my FCP. There's no longer any issues.
