The message of the commercial being...drink our tequila before you propose to your girlfriend? Get drunk after a proposal? Tech stuff aside, it's a poorly conceived commercial.
The GoPros are already so reasonably priced, why bother saving a tiny bit of money on a knock-off product that's certain to lack the QC of an established company? Not to mention app compatibility.
For the wider shots where it zooms in and follows people/boats/planes, is he shooting panoramic timelapses with multiple cameras, merging the images into super high res stills, then cropping in on the action?
Couple of thoughts. The most obvious: Why would anyone use 4000ISO when 5000ISO looks so much better? If the 5000 is truly another native ISO, then couldn't they just map the information from 5000 to 4000 by reducing the gain to get a cleaner image? Sort of like how some DSLRs will have an ISO 50 when the native ISO is 100 or 160.
Also, bear in mind that we're looking at a compressed video of a screen projection. Not that I don't believe the 5000ISO looks pretty good, but there might be more loss of information than they're letting on. (Particularly in color data.)
This is probably an editing 101 question, but how do you convert 80fps to 24fps?
I had the exact same reaction.
