Pocket 4K to Alexa Conversion

Recommended Posts

Attila does great work, he has an excellent grasp of the technical; highly recommended

That 4K 60 sounds quite good (super-sampled 10 bit)

Ironically, I've still been working away at the EC engine, and fixing copious bugs (its inevitable that when I think a thing is finished, the work has just begun :) ) That being said, I think today I've fully tested it, and everything is working really, really well.

This is a GHa Tungsten LogC render from this morning; the wheels on the far left and right are completely theoretical extreme gamut, beyond what the camera can record - the ones in the center are actual log gamut (and V3 for comparison):

EOSHD Pro Color for Sony cameras EOSHD Pro LOG for Sony CamerasEOSHD C-LOG and Film Profiles for All Canon DSLRs

All of this just makes me really excited for the X-T3 version!! Any estimates on when that one comes out? It's a really popular camera that really needs some of your help :)

So that may actually fix the dark and lifeless reds I've had? Anyway, looks like a great improvement. :)

XT3 is in the plans, indeed. At this moment, its down to documenting the process of adding a camera to the server, and then streamlining the Pdf writing process as best I can (later today). This will make a camera cycle as efficient as possible.

From the LogC alone, V4 isn't that different from V3 for the average image. When saturation becomes more extreme, V4 is quite a bit better (much, much more accurate to Alexa). And when using V4 on unintended formats (i.e. Rec709 footage), V4 holds up, while V3 doesn't. Here is a comparison with one of the more saturated images I've got (most notable shift), using Soft (most equivalent variation between 3 & 4):
