If you like shooting vides, you must know the popular video format “AVCHD”, short for “Advanced Video Coding High Definition”. It is a file-based format for the digital recording and playback and in the form of MTS or M2TS formats. It uses the MPEG-4 AVC/H.264 standard, supporting a variety of standard, high definition, and stereoscopic (3D) video resolutions. So it has been widely used for Sony, Panasonic, Canon, JVC, ect professional camcorders and digital cameras.
In fact, AVCHD has been be upgraded to AVCHD Progressive. It can allow us to shoot 1080p Full HD videos at frames per second. For NTSC, it supports 1920*1080 60p/60i; for PAL, it supports 1920*1080 50p/50i. In fact, many cameras has brings the AVCHD Progressive HD technology. For example Sony’s professional 4K camcorder NEX-FS700. Besides, the panasonic’s popular HC-X900 also uses the format. Plus, Canon’s new Vixia HF R42 also can record 60p/60i MTS videos.
FCP 7 can’t recognise 60p/50p AVCHD
However, the more popular the AVCHD Progressive, the more troubles are along with us if we import it to Final Cut Pro 7 for further editing? For many NLE’s, the AVCHD Progressive is not a standard format, it menas that may softwares can’t directly support it, like FCP 7. For old AVCHD format, we can easily use Log and Transfer it to FCP for smoothly editing. But for 60p/50p rcordings, we can’t.

Then how to bring the nonstandard video to FCP 7? As we all know FCP 7 is designed to edit Apple ProRes .mov format. And it can support 30fps/25fps frame rate well, so the best solution is to reformat it to 30p/25p ProRes supported format for FCP. Below is the covnersion guide for you. It is also for FCP X users.
