Arri Alexa 4K upscaling in post


 Share

Recommended Posts

How are productions that shoot on Alexa cameras at resolutions such as 2.8K, 3.2K, and open gate 3.4K upscaling their footage for a 4K DI and delivery? While the Alexa Mini can internally upscale to UHD and the SXT can internally upscale to both UHD and DCI 4K, this is only an option for productions shooting ProRes, and many productions shoot ArriRaw 2.8K, 3.2K, or 3.4K and go through a 4K DI. What types of software are they using to upscale?

Can't most color-correction systems like DaVinci Resolve output a project at a different resolution than the original?

Yes, Resolve can. You can scale the image so it fills the frame. People may also put the footage through a Teranex. I have found that uncompressed 2k or 3k footage can upscale very nicely.
