For context: I'm not an owner of either, nor a particularly big fan of the 4.6k... But to answer your question "Why buy the Ursa mini over this?"
• Better dynamic range
• Higher resolution allows for reframing / stabilization
• Internal RAW
• BM is unclear about max. framerate, but both look to be limited to 60 fps internal at 4K. 120fps on the Cion looks like it's just via external recorder.
Great interview, thank you Mr. Van Hove!
Wouldn't the constant spray of water keep the temperature down? Not that this is a particularly practical test to begin with... but I mean...
Agreed - missing HDMI rec trigger seems nuts to me :) Curious, why would you use the d-tap -> LP-E6 instead of d-tap -> 12v input? Is it for the built-in regulation?
The battery life isn't awesome, but there's a lot of work being done by a little LP-E6 battery :) I am seeing just over 1 hour of usage per battery (and it takes 2 at a time, so 2 hrs use total) when shooting indoors. Shooting cold exterior yesterday, that dropped to about 40 mins/battery.
Comparing to the Blade, that's less runtime before swapping... but the Blades I've rented always come with Sony battery plates, so it's not an even comparison. Those are much larger batteries. I'm not super familiar with the Blade, but maybe someone else has used it with Canon batteries?
In terms of real-world usage, I'm happy with getting 1.5 - 2 hours before swapping batteries. I'm stopping to swap cards before then anyways. I'm also happy that it uses LP-E6s, since I already had a ton of them :)
If you're considering both, consider that the VA will do 60p and the Blade will not. The screen & interface on the VA is also much nicer. If you can put up with glitchy software for the first while, the VA seems much more capable in the long-run. It is working for me right now as a "dumb" recorder, despite a HUGE amount of software bugs (formatting cards, timecode display, changing recording formats, no record trigger, etc) that will get worked out in time.
