What is Build 16?

That of course would lead to some interesting effects on shots with a fair amount of motion... Might be the new hot thing for pop promos?

Another thought: since the recording of the image is completely electronic, couldn't it be posibble to record multiple exposures at the same time?

Meaning not have alternating exposures, but parallel. I.e. stream 1 records 1/4 of the exposure time, stream 2 at full exposure.

Hey, one could even go wild and have stream 3 record only every other frame, but with double exposure time.

Am I making any sense?

Not really. Unless you can figure out some way to stop the subject moving between reads, this technique would achieve nothing useful.

The Arriscan film scanner does something like that, but it's taking "photographs" of a stationary frame of film, a completely different situation.

Subtract Ch2 from Ch1 on the mixer and feed mike in to the Ch1

This way you cancel the noise in the Ch1 with phantom power on.

Try it it works.

Hey Andrew, how ya' doin'?

Can you explain this a bit further. I don't understand. Are you talking an external mixer?

My goal is to have at least 2 phantom power mics but can live with 1 phantom power and one non-phantom powered. Could you do this with this scenario? Probably couldn't monitor both at the same time though, right?

Cheers,

OK. Thanks Jim.

Exterme Build ?

higher datarate ? not just Redcode 28 or 36 but 72 or even 100MB/s in 4K.

I disappointed for the uncompressed Raw port development.

Uncompressed RAW materials can last longer than any future codec holds , and always only leaders have their options.

S.Two and Codex and others coming to record uncompressed Raw files with log table.

I'm not sure what you're saying here Andrew. If you're using a mixer, then you don't need phantom power.

Here is bit more explanations:

Basically any software that allows you to process two or 4 channels and mix it together with the option to invert one of the channels will do the trick.

Since the hiss is the same in the phase and almost the same in amplitude on all the channels ( I tested ch 1/2 and ch 3/4) I presume that you can use ch 1 and 2 for recording and ch 4 as a "reference" hiss channel. Combining inverted (-) ch 4 with any channel that contains the hiss will cancel this hiss.
In my experiment I manage to cancel it completely, not detectable difference from the no phantom power recording versus phantom power recording of the very quiet room silence.

Shutter speed bracketing is one of the form of exposure bracketing.
I have heard arguments that on moving objects it is difficult to get good results.

I did experiment with laps shots where only shutter was changing while filming runners or just simple panning. So far I have good results.
Imagine that instead 180 at 24fps shutter you use 90 at 48fps and you combine two such 48 fps exposed frames in to one 24fps frame. What you get is one frame with the blur equal to the blur of the 24fps frame.

Now take two 48fps frames and use one with shutter set to 20 and the other frame set to 320.
Well 4 stops difference.
We could even do 3 steps bracketing like on all higher end DSLRs
Take 72fps and shoot 3 frame groups using shutter set to 20 - 80 - 320 for each group of 3 frames.
Then combine 3 frames at 72fps in to one at 24fps, well blur will be exactly the same as on frame at 24fps.

And it is easy to add to RED menu, two more lines there for the shutter speed setup.
The first frame line (existing) then right under the second line for second frame shutter speed and the line for the third frame.

It is not much to ask for, to make the RED camera the first one in the world supporting HDR moving pictures.

Maybe Jim is already playing with this feature? "you will be surprised"

You can use this tool to combine two channels in to one with one inverted.
See below picture.
See the (-) sign.
This is in Soundbooth and Premiere.
Audition has it build in on all mixers there.
Some mixers (soft or hardware) do have this button.

Yes, you can use ch 1 and ch2 for recording with phantom power on and the third channel (3-rd or 4-th) just 600 ohm terminated, no mike there.
Enable all 3 channels on the RED camera, so all 3 will be recorded.
Then extract all 3 audio track and blend the 3-rd one with the first and with the second with (-) button pressed on the 3-rd channel.
