There a certain people accusing others of posting "lame" yet they hardly know the tiniest bit of a professional production it seems. I mean, please at least be so decent and read through the thread and stop insulting people in general, especially when they showed their acclaimed work here.
For the SD card: don't be lame, make your homework and start reading, that recording ProRes is not possible on the SD card. Only on the internal SSD. There's not even an option for shadow-copying later on or so ...
The transfer speeds vary but are likely to go down to something
200 - 250 Mbyte/s (or even lower) ... a full internal SSD would at least require 1 h 20 mins at that speed. And it certainly has nothing to do with
@canadian drone videos "this guy needs to have a MacBook to use in the professional field". It has to do with the connections. Latest TB3, TB4 or other USB 3.x transmitting speeds and (NVMe) SSD hardware is certainly part of everyday's PCs and laptops too. So why it's not transmitting faster or throttling from the drone ... no one knows by now. Interfaces could do more throughput. And Philip Bloom is showing the transfer on a Mac, so I guess, he knows, what he's talking about.
And as said, it's not just a few minutes, it can be quite long especially with the change of loading batteries etc. The usual way is shooting, shooting, shooting and offload or hand over your material at the end. Or offload it while changing batteries by inserting a new SD ... but exactly that flexible handling is not possible anymore with ProRes without investing 15 mins+.
That might not be a problem to you or others (it's not even for me) but COMPARED to today's standards, that is a sub par condition. DJI claims, that a removable media would talk to much weight and reduce flight time, but yet, having the option would still be a great thing.
Well, I guess it is, or is not. But don't label it "for the pros" and keep talking they are doing it wrong.
They know their stuff and how the workflow is supposed to be.
