    You can go the other way and calculate a theoretical extraction's resolution. Here's Super 16: 12.52mm * (6144/27.03) = 2.8K.
    Well, thanks that's awesome information :)

    The scratch mics on the camera are decent btw, but you like always, will likely enjoy the sound out of true and good microphones and perhaps an advanced recording solution. For instance, though I was ridiculed early for experimenting with 32-bit audio workflows via the field recorders, I now know several productions exploring that as their pipeline. Tech is evolving honestly, even in sound. But generally it's been a much slower world of advancement in that world compared to fiery forge of camera advancements.


    I think so too, that it gives such an impression through another sound source




    Nie ma problemu, stary! Ok, rozumiem co mówisz. Uważam, że dźwięk nie został zarejestrowany w aparacie. Phil Holland może to lepiej wyjaśnić. Mówił jednak o tym w poście # 238.

    I think what Phil said makes sense. :)

    Just upscaled the 6k file (Phil's) to 8k and it looked great. Not that 8K is a mainstream deliverable (yet) but good to know it can be done with ease.

    Arri does upscaling since the beginning of their 4k workflow. No one seems to care.

    Can I ask what is the best workflow for the upscaling process? Was always curious about this topic.

    I look forward to using the 16mm glass from my Bolex for 2k. Will there be something like a 2.5k -2.8k mode that would work for S16/1" format glass? Bolex vignettes slightly in the corners at 1080p on some 16mm glass, 5 micron pixels.
    I have a really nice Angenieux 12-120 HEC that is my usual run and gun lens. Vignettes a bit below 20mm or so, but covers 2k 2.4:1 scope OK without vignetting.

    hi Phil,

    Thanks so much for your testing and all the sharing of info.

    Appreciate hearing about the boot up time and be very interested to see how this tracks. This is in fact a real biggie for a lot of small crew, independent operators - in particular in reality/documentary productions.

    thanks

    Aaron love these calculations.

    Here's a quick preview of an 8K Komodo Sensor:

    8192 * (27.03/6144) = 36.04

    Notice it's EXACTLY Vista Vision. Not sure if that's a coincidence or not, but worth noting.

    Yes, I've been giddy over that since they announced the sensor size of Komodo. My brain immediately went to DSMC3 and what's theoretically possible. An 8K full frame global shutter with no cmos smear would be the perfect step up from Helium for me. I'd also love if they decided to do a "gemini" treatment on it and go for taller than 1.9:1 since several companies are now doing anamorphic for larger formats. Thinking even further into the future I would love if they just did a 10K by 10K wider-than-full-frame square canvas where you simply extract what you need from it -- essentially a multi-aspect ratio sensor with surface area to spare. But that's all a discussion for another time. :)
