The Alexa Digital Cinema Camera has been used for almost a trimester now and when it comes to chromakey shoots
|green screen shoot aka chromakey|
users tend to give up on the Alexa 4:4:4:4 recording capabilities by utilizing a red camera instead.
The argument I keep hearing is the ProRes 4:4:4:4 does not handle compositing (chromakey) as good as Red raw files.
Knowing that Apple ProRes 4:4:4:4 (called 4 by 4) was created and designed especially for that purpose, that is compositing since its last 4 in the 4:4:4:4 codec represents the alpha channel, I am very skeptical and would like to be very careful about the answer I would give since the response many directors of photography will give you is: "The Red can record in 4K so why downgrading to HD 4:4:4:4 with the Alexa"
As a response, I invite you to come a see it for yourself at our January 20th Workshop entitled: "The Alexa workshop" where we will do what was just mentioned above.
Space is limited to two groups of 4. so make sure you book your seat soon.
