Trying to deploy it in unsuitable circumstances leads to difficulty later in the production and consumption cycle. 1 Origination Stage Video compression should be avoided at the origination stage. Some cameras compress the video as it is written to tape or disk inside the camera. These devices never yield an uncompressed output.
