[Bf-committers] libredcode

[Ton Roosendaal]

Hi all,

Sorry for slow reply, the past days I'm way behind mails - people here want attention too! Andrew Hunter's observations are all correct and in the line of our actions already :)

This is the plan sofar;

- Camalot is testing the new Sony F65 now, we might get that - or at least we get the red epics. That decision is being made in a few weeks from now. 

- I realize Red is not very 'open', nor interested in supporting that. I have contacted them about our work, but the contact remains very shallow.

- In case we will use the Red Epic, we will for sure arrange a test with Camalot first (a month before we film).
 
- We can use a closed workflow to get the files from the Red cartridges converted to something readable for us (openexr preferably) - using the Red software. That's for me then the start of the "open vfx pipeline" :)

- There's also a chance we support someone to help developing redcode file conversion. Getting this opened up is something more people (studios too!) would like to see. Feasibility unsure.

- If you have Red (Epic) footage for us to test that would rock! But it should be in a compatible free license (Creative Commons Attribution). We already had Red One footage from another source, which is being copied to xiph.org for everyone currently;

Thanks,


-Ton-
