I posted this on my site as well - in case one of these is down.
Sony PMW-EX1 free workflow | mishra.tv Productions (http://www.mishra.tv/wordpress/?p=222)
For the shoot we used a Sony EX1 camera. Excellent camera, though the video does not look as filmic as the 5D/7D. The problem is that the lords and masters at Sony expect every EX1 owner to shell thousands for a FCP license just to use the camera footage. Screw Them!
I wanted to edit it with iMovie and use Cineform as an intermediate codec. This is how its done.
The EX1 mp4 files are actually 35 mbps mpeg2 files with mp2 audio.
From this site – FFmpeg Howto (http://www.itbroadcastanddigitalcinema.com/ffmpeg_howto.html#Muxing_and_Wrapping_MPEG-2_Program_Stream)
we get the process to extract the mpeg 2 video and audio streams separately and then recombine them into a mpeg2 file.
From this site – HOWTO install and use FFmpeg on Mac OS X Leopard Hay Kranen (http://www.haykranen.nl/2007/11/21/howto-install-and-use-ffmpeg-on-mac-os-x-leopard/)
I learnt to install and build ffmpeg using macports. Remember to install XCode from the Optional Installs directory of Snow Leopard (or any other OSX).
Ffmpeg can fail on certain conversions. So we can use mplayer for an alternative workflow. 7.7.*Using MEncoder to create QuickTime-compatible files (http://www.mplayerhq.hu/DOCS/HTML/en/menc-feat-quicktime-7.html)
I combined this into an Automator workflow. The file is attached in this post.
You need to install XCode from the Optional Installs folder on the OS install DVD.
Also install Perian and VLC.
You also need to install macports and then build and install ffmpeg as shown here.

Now copy the folders inside the BPAV directories from the SDHC card to your archival hdd. There are a number of .mp4 files there. These cannot be used by imovie or FCE or any other device at this time.
Download the attached EX12MOV Automator bundle (Dont use the EX12MPEG2) and place it on your Desktop. Double click it and use Finder or the Automator window to browse to the BPAV directory. Select ALL the files to be converted. Make sure you select files and not directories. Drag them to the Automator window if using Finder. Make sure that the frame inside Automator with the files is on top of the script. Press the Play button on the right.
Let it do its thing.
When its finished check the files - an easy way is to sort them them size inside Finder. The mov files should be approx 5-10% smaller in size than the mp4 files. Play them to make sure.
Now these mpg files can be shared and used in any editing app. You can even use Quicktime Pro to edit them if you so desire.
NOTE: You can use VLC to play them. I'm not sure if you need the 10$ Quicktime MPEG2 component to view them if you only use qt.
