What happens when you hit record on the camera? Does the SDI jump back to 4k crop or does it maintain the clean "5k" look around? I'm confused as to how this could work in practice... Too bad you couldn't record 4k or 5k over 3G-SDI (like the C500 or FS700?), because then we'd essentially get access to the full sensor/full resolution recordings.
I don't think he was saying he'd prefer an exernal-only 4K camera (ie FS700) over an internal-only 4K camera (Scarlet), merely that he wishes Scarlet did both.
Ha, yeah. I obviously prefer internal and REDraw, but it'd cool to be able to get the entire 1.3x 5k sensor supersampled 4k even if you had to record externally. 5k Resolution is awesome, but using the entire FOV of the sensor is more awesome.I still dont know how this could be functional in practice.
Well, as long as 1080 ProRes HQ is good enough for you, you should be fine. After all, many folks shoot that on Alexas…
Yes, when you hit record the signal out the SDI keeps the look around, which gives you the full FOV of the sensor.
I much prefer shooting RAW, but it's not always up to me, I have already ran in to clients (all have been sports broadcasters...) who would rather shoot other camera systems due to not having the ability to deal with R3D in a timely fashion. I purchased an external recorder for ProRes deliverables (Samurai is soon to be DnxHD as well), I bake in a bit of a look, and the clients have been stoked. I primarily shoot specialty/feature for them not sports coverage, the client doesnt want to shoot on an ENG cam because they want the cinematic look but they also very often have quick turnaround times, it's been awesome to be able to keep them on RED because of the ability to go straight to an editable codec. These are jobs that would have gone to the F3 or similar. I've seen many a producer check out the project we are on and say to the supervising producer "oh, your shooting on RED, this is working for you... huh" :) That producer now sees it as a viable option for them.
By yeah with regards to Alexa, Scarlet now has a bigger sensor, twice as much supersampling (5k compared to 2.8k to 1080p), and from what I've read, cleaner high ISO performance when "baked in" out the monitor path. Those are three pretty big advantages for projects that are finishing in 1080p. So this kind of recording does have it's place for certain types of shooting/projects... well, until 4k displays saturate the market.
