What is the best solution for editing AVCHD footage in Final Cut Pro X? This is a frequently asked question by FCP X users. AVCHD is an HD video format jointly developed by Sony and Panasonic that uses Advanced Video Coding (AVC) compression (also known as MPEG-4 part 10 or H.264) to achieve high-quality images and low data rates. Generally speaking, AVCHD footage is usually saved in MTS or M2TS container format, which are widely used by Sony, Panasonic, JVC, Canon camcorders. However, AVCHD files are not natively supported by Final Cut Pro X and must be transcoded to FCP X friendly codecs such as QuickTime movie and Apple Intermediate Codec before importing to FCP X. To lower the quality loss during transcoding, Apple introduced in 2008 the Apple ProRes family to help Final Cut Pro X works more efficiently with HD contents. By transcoding/converting AVCHD to Apple ProRes codec, the possible best quality is retained in post-production workflow and you can then edit the resulting media files just as you would edit in QuickTime Movie format. Besides, the rendering time is saved as Apple ProRes codecs are natively supported by FCP X. The following guide tells you how to convert AVCHD to Apple ProRes 422 codec for use in your Final Cut Pro X sequence.
Required software: MTS/M2TS to ProRes Converter for Mac
About the software: This is an AVCHD transcoding tool for Mac OS X only. The Mac MTS/M2TS to ProRes Converter deals with AVCHD footage straightly from Sony, Panasonic, JVC and various other camcorders and exports HD contents encoded in various codecs for editing and playing back. The FCP X friendly codecs includes Apple ProRes family (ProRes 422, ProRes 422 LT, ProRes 422 HQ, ProRes 422 Proxy, ProRes 4444), DVCPRO, HDV, Apple Intermediate codec, etc.
Software availability: The Mac AVCHD to ProRes Converter is offered for $35 only, and is free of update. You may download a trial of the MTS/M2TS to ProRes Converter for Mac software to try it out.
Detailed guide of converting AVCHD to Apple ProRes 422 codec for Final Cut Pro X:
Step 1. Run MTS/M2TS to ProRes Converter for Mac. Click “Add” button and browse to the AVCHD footages either from scratch disk or cam HDD for loading to the converter.

Step 2. Click on “Format” bar and set a FCP X friendly format in dropdown-list. You are advised to “Follow Final Cut Pro” template and “Apple ProRes 422 (*.mov)” format. AVCHD has a much higher compression ratio than Apple ProRes, so the ingested files are significantly larger than the original files. For example, a 2-minute native AVCHD file is about 200–300 MB. After transcoding to the Apple ProRes 422 codec, the file size can be as large as 2 GB. If you prefer smaller file size, choose “Apple ProRes 422 (LT) (*.mov)” instead. The “Apple ProRes 422 (Proxy) (*.mov)” format offers file size at SD levels and is recommended for 480i/p and 576i/p shootings.

Step 3. Click the “Settings” button and customize proper video/ audio parameters if necessary. Video size, bitrate and fame rate are flexible and can be adjusted as you like. E.g. Set video size to 1920*1080 when you feel like to keep 1080p as the source file features. Or set smaller bitrate to further cut down export file size. You may skip this step as well.

Step 4. Click “Browse” button to set a location on your HDD for the output video file. As I mentioned above, the generated file size could be huge, so make sure there are enough disk space.
Step 5. Click “Convert” to start transferring AVCHD to Apple ProRes 422 codec. The conversion process may take long time due to huge file size but trust me– this Mac MTS/M2TS Converter is faster than most other AVCHD transcoding tool. And it will not bother to render the converted files in FCP X. After conversion just click the “Open” button to locate converted video files for FCP X post-production seamlessly.

Apple claims that iMovie ’09/11 supports most commonly-used video codecs, including DV, MPEG-2, MPEG-4, H.264, AVCHD and AIC. However, due to the wide range of media types, and the different ways manufacturers store video on these media types, not all AVCHD camcorders are compatible with iMovie ’09/11. In this case, the workaround for you is using a Mac AVCHD to Apple Intermediate Codec Converter to convert/transcode AVCHD MTS/M2TS files to AIC for iMovie.
About Apple Intermediate Codec (Quoted from Wikipedia)
“The Apple Intermediate Codec is a video codec designed by Apple, Inc to be an intermediate format in an HDV workflow. It features high performance and quality, being less processor intensive to work with than other editing formats. Unlike native MPEG-2 based HDV – and similar to the standard-definition DV codec – AIC does not use temporal compression, enabling every frame to be decoded immediately without decoding other frames. As a result of this, AIC takes three to four times more space than HDV.
AIC is available only on the Mac OS X platform and cannot be read on other platforms to date such as Windows or Linux. All Mac OS X software which makes use of the QuickTime codec libraries – primarily Final Cut Studio, Final Cut Express, and iMovie, but also freeware such as MPEG Streamclip – can use the Apple Intermediate codec.”
