Final Cut Pro is no doubt a great choice for video hobbyists and filmmakers to make creative movies from camera/camcorder recordings. But users who are not quite familiar with FCP may face obstacles even when importing camera clips, especially those in MTS format. See an example, “Hello we captured footage with the Canon HF100 Hi-Def Camcorder, transferred the video files onto an external drive. We're now trying to import those MTS files into Final Cut Pro 6.0.5 but it seems they are not supported... how do you import them?”
If you have MTS files, we assume you are using an AVCHD camera. If that’s the case, when you capture the data files from the SD Card or whatever media you are recording to, it is critical that you capture the entire directory structure. From there, you can use File->Log and Transfer and select the base directory, and Final Cut Pro will import everything for you.
The following screenshot shows the AVCHD Structure on card/disk
AVCHD is a format created for consumer camcorders. The structure actually mimics the basic structure of Blu-ray. Some TV sets and Blu-ray players can play these clips directly from the SD-Cards. For editing only the .MTS files in the STREAM folder are needed. They actually contain a H.264 video stream (some tools like a MTS to FCP Converter can re-wrap/transcode these MTS streams to ProRes .MOV for FCP without changing any data).
FCP should read the mts videos if the AVCHD volume structure is kept as unaltered. Otherwise, Final Cut Pro would not read the .mts files directly. If you only saved some loose .mts videos without keeping an entire AVCHD file structure, you need use a MTS to FCP Converter program on Mac to do format conversion before editing. The recommended solution is Aunsoft MTS to ProRes Converter. It runs $29. Launch Aunsoft, drag your files in, select ProRes MOV as target format, click the convert tab and that’s all. Now you can edit MTS movies in Final Cut Pro with ease.
Apple has designed the ProRes codec to work quickly and easily with Final Cut Pro, that’s why Aunsoft MTS to FCP Converter provides expert Apple ProRes settings for FCP.
Some cameras automatically chop footage up into separate files when they hit 2GB or something else (maybe 4GB). If you want to join MTS files seamlessly so there are no hiccups in the flow, Aunsoft software can also help you achieve the goal by ticking off the checkbox before “Merge into one file” option.
