Hi Robert,
There are a number of sources available that come to my mind.
For camera RAW (in this case, RED camera files) you can visit Mammoth HD at
http://www.mammothhd.com
Artbeats has many shots that are available that were acquired in both RAW/RED format and from 1080 and 720 sources. They are at
http://www.artbeats.com
istockvideo may also have some, as might revostock.com
Best regards,
Ron Lindeboom
