There is one warning about AVCHD files editing in iMovie or Final Cut. When you import your AVCHD footage from Sony or Canon HD cameras into iMovie or Final Cut for editing, the two applications actually do not edit in native HD videos. They transcode your videos into the Apple Intermediate Codec (AIC).

The Apple Intermediate Codec is a video codec designed by Apple 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.

In fact, the Apple Intermediate codec will not cause much image quality loss like someone feared. The transcoded video looks quite acceptable in iMovie as well as Final Cut. You download your AVCHD files from your HD camcorders and convert to the intermediate codec, edit your footage, and then when you output edited files, iMovie or Final Cut will reformat the videos into DV or HDV.

Evidently, it’s sure quite a good day to edit. But there is one big draw back unavoidably. When you transcode into Apple's intermediate Codec, the AVCHD size become even bigger. Much bigger. And accordingly it will take much more spaces of you Mac. Take Final Cut Pro 6 for example, the transcoded AVCHD video will actually take up about ten times more space than it normally would on your camcorder. A 2-minute, 200MB AVCHD file can take up as much as 2GB when transcoded to AIC.

You may find the fact that your 10+GB AVCHD footage (.MTS file extension) produced by the camcorder like Canon Vixia HFS11 is going to be ten times bigger in Final Cut Pro 6. So just quit the idea of editing AVCHD in Final Cut and find a reliable, quality lossless converting tool for AVCHD files conversion.

Aunsoft AVCHD MTS/M2TS Converter  is such a good program, which can convert Canon .MTS files to formats you can use, and it allows you to trim and crop the footage, it also offers high resolution output (like 1280x720) and it deinterlaces MTS/M2TS file. Plus, the software is terrific for large files (some of my files are 10+GB) and of course, it doesn't automatically transcode into an intermediate codec the way that iMovie or Final Cut do -- so your output could take much fewer time with this Aunsoft MTS converter.

I will now give you a general guide on how to use the converting program.

Step 1. Load AVCHD files to Aunsoft AVCHD Converter

Drag and drop AVCHD-MTS files into the program. You can also click “Add” button to load MTS or M2TS files into the app. Then you will face the interface as below.

Step 3: Choose output format

Choose output format for iMovie or Final Cut. In my case, you can choose “AVI HD Video” from “HD Video” section from “Format” drop-down list. More than that, Aunsoft AVCHD Converter provides with many other options for your different devices or purposes, such as iPod, iPad, iPhone, Apple TV, PSP, Zune, Audio output, Flash Video, etc. You can also custom your destination folder for output videos in “Export to” list.

Step 4: Merge MTS files and Convert

Join MTS files (optional) and convert. Before you start conversion, you can check “Merge into one file” to combine multiple AVCHD files together and output to one single video.

That’s it, the whole process of converting, deinterlacing and merging AVCHD MTS/M2TS files with Aunsoft Mac version of MTS/M2TS Converter.
