For example, the Axis one was shown on a much smaller frame than the Avigilon one.
Whose side are you on anyway? ;)
Yes, I know it's smaller, I actually had to digitally zoom it a bit more to normalize it with the Gimp one, thus even further degrading the Axis pic.
Fortunately we have no need for my speculative comparison since we have your more grounded one:
Gimp's digital zoom levels appear to be different then Axis's. For example, 12x on Gimp on a 29MP image zooms in a lot further / tighter than 12x on Axis HD.
Twice as far, by my estimate. And so I agree, the Gimp image appears zoomed in far more That could certainly be what I subconsciously picked-up on and good reason for the quality difference. That would satisfy me and I would be ready to accept it, case closed, if it weren't for this baffling (to me) picture:
Here's the thing, if Axis reported digital zoom levels differently than others why do these pictures match? Not only are they apparently between two different cameras mfrs. Axis and (Canon?*), but they also show that Axis' digital zoom is reported in line with the way their optical zoom is. Is Gimp zoom different than optical zoom or do you think Axis reports digital zoom differently over 4X?
You may be right in the video that "any camera has more than enough digital zoom", but you also contend multiply that 4x is more than enough, even for multi-megapixel cameras. And if you are right about the zoom reporting differences, then this would not apply at least to Axis cameras, (and whoever may have copied their way of reporting).
At the risk of speculation, Occam's razor suggests that maybe their was another click still left in the zoom range when the video was made?? (I know, I know, I'm ordering a Q1755 right now. ;)
