Video editing software on Mac like iMovie, Final Cut Express, and Final Cut Pro still have big troubles in recognizing footages shot by AVCHD camcorders. The problem is especially obvious for those people who do not have the latest version of these editors. Because these AVCHD cameras such as Canon HF S11, HF S200, JVC GZ-HD620, Panasonic AG-HMC40, etc. are all recording videos in the format of MTS or M2TS, which have not got native supports from the above mentioned Mac editors to full extent. To make MTS files possible for editing on Mac, here I would recommend you Pavtube MTS/M2TS Converter for Mac, which will convert MTS to MOV and other container formats that are accepted by often used Mac editors-iMovie, Final Cut Express, and Final Cut Pro. The application works well on Mac OS X and handles TS, TP, M2TS, M2T format as well. The following guide tells you how to convert MTS files to a workable format for editing on Mac step by step. If you are frustrated by the similar problem, please read on it to find out the solution.
1. Run Pavtube MTS/M2TS Converter for Mac and click "Add" button to load MTS files shot by your camcorder to this program.
2. Click on the drop-down menu of "Format" to select a compatible format for your iMovie, Final Cut Express, or Final Cut Pro. I select "MOV-QuickTime (*.mov)" as an example.
3. Click "Settings" button to adjust audio and video parameters
You are allowed to adjust audio and video parameters like codec name, bit rate, aspect ratio, frame rate, and audio channel in the following window. In principle, the larger input values, the larger file size, but accompanying with the better file quality; the smaller input value, the smaller file size, but accompanying with inferior file quality. That is to say, if you want to do advance settings, you’d better make a balance between the file size and the file quality.
4. Start converting MTS files
Once all the above settings are finished, you can click "Convert" button to start converting MTS/M2TS AVCHD files into iMovie, FCP or FCE supported format. The interface below will show you clearly about conversion progress, time elapse, left time, generated file size, and estimated file size. After conversion is done, you can easily find out the output files for editing via clicking "Open" button.
The end! Hope this helps.
