Transcoding Canon T2i 550D Mov Files for Sony Vegas Editing

Tutorial on how to install and use a pre-render workflow for your .mov files to easier editing.


Funny even though I clearly state on my contact page that I am not an expert in DSLR video I still get a few very technical questions every so often. I don’t mind them at all, keep the questions coming, because if I don’t know then I want to dig in to it and find out.

I got several people asking me why their Canon video clips within Sony Vegas looks choppy or have a shutter effect or just show a black screen.

For years now I have been getting those same issues and while I just upgraded to a very powerful desktop and that doesn’t happen as much as it used to.

This mostly has to do with the .mov file that Canon creates in the camera that is very hard for Vegas and all other NLE to deal with since it is a compressed format and it is hard for it to decode it at the same time it is allowing the file to be edited.

Most of my videos are pretty easy to do since they have only one track of video and very little special effects so I haven’t need to do any pre-rendering yet. But since I have a larger project with tons of tracks coming up I wanted to try it out.

The only one that I found was free is the Square 5 Mpeg Streamclip converter. The other option I can see is a paid one at $129 at NeoScene CineForm.

After you download the program for Windows, extract it to a directory you like and then click on the executable.

Then if you are like me and don’t have the Avid QuickTime Codec, you can get it download it.

The rest of the instructions I found from Tom Mueller on Vimeo.

” File, Export to Quicktime

Choose Avid DNxHD.

Click Options button

Color levels RGB

Click the tiny sliver of a box at the bottom of the window (this is a bug). It will allow you to select the bit rate for DNxHD. Select 1080/24p DNxHD 175 10-bit. Or select 1080/24p 115 8-bit. Experiment with both.

Hover over the Uncompressed selection and the OK button will appear. This is another bug. Click OK.

Set quality to 100%

Uncheck Interlaced Scaling

Select 1920×1080 unscaled
