When rendering to 2K Cineon, 2K DPX or 2K RED files, the files will be saved as if they were 1K.

This occurs when the Render Proxy setting is set to half resolution, which is the default Render Proxy setting in Color 1.5.
Note: This will only affect DPX and Cineon files if you have previously created proxies.

Programs
Color 1.5

Solution

To fix this problem, change the Render Proxy pop-up menu to Full Resolution in Color User Preferences:

  1. Click the Setup Room tab in the Color window or press (Command + 1).
  2. Click the User Preferences tab
  3. From the Render Proxy pop-up menu, select Full Resolution.

Note: If you are using a 4K RED file in a 2K Sequence and the rendered export you want to do is 2K, then Half Resolution is the correct Render Proxy setting.
