Do you mean not capturing the full 4K resolution? What in the parameters do you see as problematical? You don't like 4:2:0? 8-bit? Nothing to do with 4K. You want a higher bit rate? what else is new.
What do you mean?
And, it is obvious that no HD cameras are capturing full HD (1080 resolution) by a long shot. And almost all are shooting 4:2:0 and 8-bit also. So?
1) Low frame rates. Terrible judder in most of the sample clips posted due to low frame rates I feel sick watching them and this isn't just the AX100. We've had 60 samples per second motion for decades, first in the form of 60i and recently 60p. From day one camcorders either wouldn't do 24fps or 30fps, or it was buried away in the settings because video at those frame rates isn't good, unless you shoot like film, and no use for sport or fast action. Now as the LSIs struggle to do 4K and only go as far as 30fps (just 25fps in 50Hz countries on the AX100), it is suddenly the in thing, but it looks as terrible as it always did
If you know what you are doing and shoot like film, then the requite motion blur defeats the object of 4K's potential feeling of reality.
2) Very compressed, looks good downscaled or on smaller monitors, but everything looks good scaled down. It is what it is, 15Mbits/sec HD times 4.
3) No extra color information, does it even do Deep Color like AVCHD? Still 16-235.
4) 4.2.0 at 8bit doesn't bother me so much.
At 24fps or 30fps the resolution that can be resolved on moving subjects, due to the sample and hold nature of LCD and OLED displays is going to be very poor. The UHD specification doesn't include 30fps as a recognised frame-rate to qualify as UHD, why is this? Only 24fps and 25fps are included for legacy and film transfers, with 60fps being the minimum for video, with an aim of 120fps eventually. Presumably this is why these camcorders do not have the UHD moniker, but just have 4K.
For anything with moderate to fast action, you are going to need to record in 1080P on these camcorders, it even says that in the instructions, otherwise it is a nauseating juddery mess. I'll take 4K at 60fps thank you, and not before, otherwise it is one step forward, two steps back!
