Color profile (RGB or YUV)of video file

Hi All,

I am developing an AE plug-in and integrating the plug-in on Premiere Pro.

One of the requirement is to identify the color profile of input video file, meaning if user imports a file from Premiere Pro, the requirement is to identify the whether it contains RGB or YUV representations.

Please let me know AE or Premiere Pro API's to find RGB and YUV representations.

Thanks in advance.
