Learn how to Transcode AVCHD to Adobe Premiere/Avid MC/FCP X

[size="4"]Learn how to process AVCHD Media for Editing in Adobe Premiere, Avid Media Composer, and Final Cut Pro X.[/size]
[size="4"]You may encounter issues if you are working with an AVCHD container that has .mts files, you will immediately notice the following drawbacks.[/size]

Final Cut Pro X: Extremely slow processing times when importing .mts media.

Adobe Premiere: Provides immediate access to .mts files, but with a very annoying audio conforming process that decreases system performance until finished.

Avid Media Composer: It is unable to directly import or link to .mts files.  You must transcode the media ahead of time.

So with that being said, transcoding your media into a friendlier video format will provide the following advantages.

*faster import times
*improved playback performance (i.e, multicam playback)
*more real-time effects
*faster render times
*faster export  times
*cross editing platform compatibility
*better for archival storage

There are many third party software products that convert AVCHD media and/or .mts files into a different format.  For this article, I successfully tested some conversion software called Brosoft.

In the above example, I successfully converted five .mts files from within an AVCHD container into a single Apple ProRes 422 QuickTime movie.  Converting 10 GB of media took approximately 1 hour to convert using a Mac Book Pro Retina.

Once the conversion process was finished, all three software editing packages (Adobe Premiere, Avid Media Composer, and Final Cut Pro X) had a much easier time dealing with the ProRes media.

Step 1: Install and launch this MTS Converter for Mac on your Mac. Transfer your Canon Vixia footages to the converter.
Tip: If you want, you can merge several AVCHD clips by ticking “Merge into one” box.

Step 2: Click "format" bar to choose the output format.

For FCP: Click and choose Final Cut Pro-->Apple ProRes 422(*.mov) as the output format.
FCP 6 or ealier version only can support ProRes 422 and ProRes 422(HQ). FCP 7 or above can support Pro Res 422(LT), Pro Res 444Pro and Res 422(Proxy).
For iMovie: Click and choose "iMovie and Final Cut Express--> Apple Intermediate Codec(AIC)(*.mov)" as the output format
For Avid Media Composer: Click and choose Avid Media Composer-->Avid DNxHD(*.mov)

Step 3: You can tap "settings" to customize the output parameters, adjust the resolution, bitrate as you want. Set video size as 1920*1080, video frame rate as 30fps is better (If the original recordings are 1080 50p, pls set 25fps)

Step 4: Click convert button to start converting AVCHD mts files to Apple ProRes/AIC/Avid on Mac OS X.

After Canon Vixia conversion finished , you can click “open” to find the output file, then you can import converted files into FCP/iMovie/Avid MC for editing easily.

1. For your original 1080/60i footages, you need to deinterlace 1080/60i AVCHD footages to remove all these interlacing artifacts from videos via ticking the “Deinterlacing” box in the Video Editor interface.
2. If the supposed size of the input files is 1GB, then the memory space should be up to 40GB.
3. Auto shutdown: Click Option and tick the box “Shut down the computer after conversion” before conversion starts.
4. 3D conversion. The Red-Blue/Red-Green 3D conversions are supported.
5. Crop: Edit --> Crop and you can get the imported videos cropped as you want.
6. Double click the imputed file, you can preview your footages in the software window.
