Does anyone know if it's possible to get 4:4:4 out of a F900/3 or is that only possible with the new F900R or an F950? If so what do I need?

The F900/3 and F900R only sends out 4:2:2 out the HDSDI cable. You'd need a dual-link output to get 4:4:4 for one thing. The F900 is not a 4:4:4 camera basically -- you need to get the F950 or Viper. After all, if you're not going to use the internal VTR anyway, why bother with the F900 even for 4:2:2? The Viper and F950 would be smaller and lighter for one thing.

Thanks David. The catch is, the F900 is mine. A potential client asked if what I wrote was possible. I appreciate your reply.

Hi,

A few F900's were modified for 4:4:4 so it is possible at a price.

Hi Steven, whose f900s were modified? Any other details?

Mike,

There was a thread on CML a few years ago. I have looked in their archive and can't locate it. I am fairly sure the writer was Michael at BandPro, I think the conversion was for Lucasfilm.

I was told by the MD of a manufacturer of live bluescreen keyer that he was present with a f900 that had a bunch of cables protruding from it to deliver 4:4:4 during a test for Lucas films.
This was before the f950s were available. The record is pretty straight about what Lucas eventually used.

How do they did it, i don't know but they did it.

It was recorded to hard drive but I doubt to 4:4:4 since the camera only outputs 4:2:2. Where did you read it was 4:4:4? No mention of that here:

Nor in the Jan. 2003 feature article in American Cinematographer.
