converting the DSLR files to the DNxHD file

This is Perrone Fords solution using MPEG Streamclip converting the 7D native files to the DNxHD file-format:




" 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 1920x1080 unscaled
