How to Transcode .mov Files

*** Update ***

I created a new tutorial on how to transcode .mov files using the Matrox VFW codecs and Prism Video Converter. There are some advantages to this method; .avi files are created which are perfect for editing in Sony Vegas, and the Matrox codecs support additional framerates, most notably 29.97 at 1920×1080, an option not found with the Avid DNxHD codec. It’s a more complete solution for PC users and it’s faster than DNxHD.

Some video files aren’t easy to edit on a PC.  That’s especially true of .mov files produced by Canon compacts and DSLRs.

What options do people have?

The best option I’ve found (if you use 24p or 720p) is MPEG Streamclip in combination with the AVID DNxHD codec.

First you’ll need MPEG Streamclip.  You can find it here. Choose the Mac or PC version, download it and install it.  Then download the AVID DNxHD codec.  You can find the codec here. Choose the Mac or PC version, download it and install it.  You’re ready to go.

Open MPEG Streamclip.  You’ll see the following screen.  Click “List” at the top.

Next, click “Batch.”

Then, the following screen will appear.   Click “Add Files” in the lower right.

Next, hold down the control key and select the files you want to transcode with your mouse.  Then click “Open” in the lower right.

Select your files


After clicking “Open” you’ll see the following screen.  Make sure it says “Export to Quick Time” in the dropdown box.  Click “OK.”

Choose the location for your future transcoded files then click “OK.”  As you see, I chose the desktop.  That’s where I’m going to find my transcoded files when the process is complete.

After clicking “OK” the the “Movie Exporter” screen will appear.   In the “Compression” dropdown menu, make sure you have selected “AVID DNxHD” codec.  Then click “Options” in the upper right part of the screen.

Choose the proper codec


Next, click the box that’s only barely appearing in the Codec Configuration screen.  I don’t know why AVID released software with such a buggy interface but that’s neither here nor there.  Click it.

Once you’ve clicked the almost invisible box, the following dropdown will appear.  Choose the profile that’s appropriate for your video.  I record (typically) in 24p with my new t2i.  Sometimes I record in 720p.  If your configuration isn’t there you’ll have to use Neoscene.  Sorry, goodbye.  Have a nice day.  I hate to say it, but 1080p at 30fps isn’t there.  There’s a profile for 720p @ 30fps.   Why is this?  I have no idea.  Back to it.

Anyway, since I record in 24p, I’m going to choose the option that says 1080p/23.976 DNxHD 175 10-bit (best quality).  Once you’ve made your choice, click “OK.”

Choose the Correct Profile!


After clicking “OK,” you’ll be back at the “Movie Exporter” screen.  Make sure your quality slider is at 100%.   Make sure your frame size matches your video. Uncheck “Interlaced Scaling.” Finally, click the button in the lower right that’s labeled “To Batch.”

Choose Proper Options


After you’ve followed the above steps all that’s left is to click “Go” on the last screen.

Click Go!


Open up Sony Vegas (or whatever program you’re using) and edit your files. If you don’t know how to render them, ask me and I’ll tell you.
