You are right. I watched the review from the YT link above and it shows the whole menu: no waveform there, only histogram.
I mean I wouldn't have expected waveform for that price, but the headline says waveform, that is just wrong!
Taking still photos really improves your video skills, I think. I am convinced that the moment I got really serious with still photography (still as a hobby though) my video work became much better. Taking photos is also a nice way to experiment with lighting - a few small remote flashes are very easy to play with, and they can emit as much light as a huge multi-kilowatt hmi. Only for a split second of course, but that doesn't matter for still photography. That way you can learn how to use super powerful light sources without having to rent a lighting truck ;)
I worked in news too, actually started there - but my first thought on the tips above was "be careful with 'think opposite'". I mean, it's good to have new ideas and new perspectives, but never forget to shoot the standard pictures first. Nothing more annoying for an editor (especially in news!) when the cameraperson was so super-artistic that they didn't deliver any "normal" footage but only artsy "new" compositions ;)
Camerawork is not only art, it is also a craft. Never forget to cover the basics, and then go crazy as much as you want!
In news or for tv formats, always delivering the basics 100% will get you more work. Delivering the best artistic shots will not get you booked again when your stuff is only useable 80% of the time. You will definitely get booked again if you can do both 100% reliably. But the basics and the reliability are more important. And I think this translates to most jobs in film or commercial work as well, nobody wants to take risks these days...
SD cards do not have a controller on board the card. It is different with SSDs, they have their own controller, and maybe some higher end cards like SxS have those too, but SD cards for sure do not, so they cannot do anything, they are just an array of NAND chips that can be accessed by the controller in a device.
However, most consumer SSDs already encrypt their writes, so it cannot be very expensive to add that capability to the controller.
However to be able to use the encryption in a meaningful way, the connected hardware - in case of the SSD the pc and operating system - have to support using the built-in encryption. If you just write normally to an encrypted SSD, the data will be encrypted on the chips, but the controller will just transparently decrypt it whenever it is asked to read. So there is a need for hardware support still, even in the case of a self-encrypting drive like an ssd.
Long story short, an extra hardware circuit that encrypts data in 256bit aes in real time is not too expensive these days. SSD manufacturers probably add them to all their products so their competitors cannot analyze the way their controllers work, these encryption circuits cannot cost more than a few bucks.
However, that will be too expensive still for consumer models.
I was wondering about that, too. Since when do more pixels automatically give you rich, deep colors and creamier tones? That has nothing to do with the amount of pixels! The original Arri Alexa only had 2K resolution and was still way better than all competitors in colors and skin tones.
