Have you got one camcorder, like Sony NEX-FS700, to record 1920*1080 Full HD MTS footage up to 60fps(50fps for PAL)? If so, have you met the incompatible erros when you tried importing 60p(or 50p) MTS videos to iMovie 8/9/11 for further editing? As far as I know many users are meeting the troubles.

How to get 1080p@60/50fps MTS videos to iMovie 8/9/11 editing?

In fact, iMovie can't support the format 1080p@60fps because it is a nonstandard format. If you want to natively edit the videos on Mac, FCP X 10.0.4 or above can help you do that sometimes. But to ingest it to iMovie, you have to firstly transcode it to a compatible frame rate with a native format, like AIC. It means that you have to use a professional MTS Converter to encode the format so that you can keep the HD quality for editing.

If you havn't got one, you can download the excellent MTS to iMovie Converter from Brorsoft. It not only can reformat AVCHD MTS/M2TS/M2T/TS movies to AIC for iMovie, it also can batch convert AVCHD clips to one file for putting to FCP, iMovie, Adobe, Avid, ect NLE's. The most important is that you can freely set the video and audio parameters so that you get the video qulity as you want with its built-in profile.

How to change 1080 50p/60p AVCHD to AIC on Mac OS X?



Step 1. Run your MTS convert program on your Mac. Then add MTS file or files to it.

Tip: Check the box of "Merge into one file", you can join/combine several MTS files.

Step 2. Click “format” and move your pointer to "iMovie and Final Cut Express" category, the "Apple Intermediate Codec(AIC) (*.mov)" is the best output format.

Step 3. Tap "Settings" to set video size (1920×1080/1440×1080/1280×720/720×480), bitrate (from 1Mbps to 20Mbps), frame rate (24p/25p/30p) as you need.

Trick: If your AVCHD file is 1080 50p, you need to set the frame rate as 25p while 1080 60p for 30p. Sometimes, the frame rate 29.97fps is a good choice.



Step 4. Start converting AVCHD to AIC under Mac OS X.

After the fast conversion, you can easily find the transcoded video by ticking "Open". Then you can run your iMovie and directly drag and drop the exported file to it for freely editing. Just enjoy your HD movies.
