CODECs for Paramount ad

@dalebenedict Video codecs can be identified either be a human-readable name, like "Advanced Video Codec (AVC)" or "Apple ProRes 422 HQ", or they can be identified in software using their "FourCC" code. FourCC is a four-character code that video files can have written into them, so that the playing software knows what codec the video is.

avc1, apcs, apcn etc that you listed are FourCC codes. I'm not aware of a canonical list of all the codes, but this is a pretty good list I found online: https://softron.zendesk.com/hc/en-us/articles/207695697-List-of-FourCC-codes-for-video-codecs

You usually don't see the fourcc codes listed in software, most video editing and playback software will display using the human readable name. So for example "avc1" is AVC aka H.264 in Premiere Pro's export settings. "apcs" is "Apple ProRes 422 (LT)" which you can find inside Premiere Pro if you export using QuickTime MOV format.

I hope that helps!
