A problem I have working with AVCHD files from my Sony cameras is converting the .MTS file format into something that Final Cut Pro X can deal with. .MTS (MPEG 2 Transport Stream) is a container file format, part of the Blu-ray specification but not ideal for post-production on a Mac.
I’ve been using Toast Titanium’s video conversion feature but results are sometimes inconsistent. On my favourite FCPX forum a couple of the resident gurus recommended ClipWrap so I thought I’d better take a look at it.
The program opens up in a single window. It accepts .MTS, .M2T and .M2TS files and converts them into a variety of formats. To get things happening I simply drag files from the desktop into the ClipWrap window, select a destination folder and an output format and then sit back and watch the progress bar as ClipWrap does its thing.
Rewrap or transcode?
The Rewrap option simply makes a copy of my file in a format that QuickTime understands. The video data is left untouched but the audio tracks are decompressed and saved as raw linear PCM. I can turn this default setting off if I wish.
The transcode option decompresses the video into industry-standard formats such as Apple Intermediate Codec, which is recommended when working with iMovie, and four varieties of Apple ProRes 422 eminently suitable for working in FCPX. ClipWrap will only transcode to formats already installed on my Mac which explains why the Avid options are greyed out.
ClipWrap has made my video workflow just that little bit smoother. For longer files I get the process happening in the background and get on with something else. If you’re dealing with a lot of AVCHD footage on your Mac ClipWrap is well worth a look.
