I saw that What are or where to find SDI record start/stop ancillary packet specification for Sony, Red or Panasonic was deleted. I wonder if questions like this really should be on topic though. The nature of signals being used in an A/V production environment can have a significant impact on what can be done in an A/V sense.
Am I missing something else about why this was deleted? Do we want to consider questions like this off topic or should we consider questions about A/V related signals that have potential application in the production realm to be on topic?
