Feel free, but I have the strong feeling that Canon does not ignore the ignorant but significant portion of potential buyers that do not crop a 4k image to 180p, achieving zoom or pan effects in post...
People don't crop 4K to 1080p, they down-sample and get increased IQ as a result.
I think he meant that a 4K original video can be reframed to a 2K video, thus achieving HD quality. I would say this is one of the reasons to shoot 4K now. If you are doing documentary work, where it is a one shot opportunity, then the 4K original framing can be off a bit and then adjusted to a better frame in 2K.
That doesn't happen nearly as often as it does with photography.
If a movie is shot in 4K, do they 'reframe" it down to 2K? No.
When a movie is shot, the framing is done once and done right the first time. The master is in 4K and a 2K (HD) video is made from that. In the future maybe masters will be done with 8K. When movies like Star Wars are shot, there's no "cropping" of the frame - that would be wasting film and people's time.
Smart people are already shooting in 4K and using it to master HD video - and not for the purpose of cropping.
If you are doing documentary work then you take a professional approach to it and get it right the first time so that minimal time needs to be spent later "correcting" in post. Doing multiple takes is perfectly acceptable and indeed preferred to "reframing."
I'll remember your sage advice the next time I'm shooting a Star Wars sequel with a DSLR.
Seriously, Dilbert your response is a total non-sequitur. Did you fail reading comprehension? No one was talking about Hollywood film production. Gsealy was talking about the not uncommon need to do some reframing or cropping in post when shooting documentary footage on the fly. If you actually had any real life experience you would know that it's not always possible to have perfect framing when shooting run and gun footage. Having a little headroom for cropping (reframing), post-production stabilization, pan shots in post production, zooming in post production, etc., is a very helpful thing.
