View Full Version : What issues will Epic overcome that have been thorns in the Red One's side?

The Strobe artefacts really get my goat. So I am hoping the shutter system on the Epic flattens them into dust.
Is the strobe issue being blown into little tiny bits?
Thanks

As much of a pain in the ass as the strobe issue is, I doubt that it will go away completely. Previous posts from Jim point to greatly improved photosite response times with the new Mysterium X sensor, but I'm not holding my breath for the issue to be gone completely.
I was brought onto a red shoot very late and upon arriving on set, to my horror, they were using stroboscopes as their PRIMARY light source. I almost had an aneurism. Somehow the producers, director, dp, ac (who works as a red tech), all failed to think about testing the light source, or even getting a synch-system for the strobes.
Needless to say if you're going to shoot strobes, RED may not be the best tool for the job.

Main difference will prob be much faster data rates - allowing high frame rates in 4K, potentially also more generous REDCODE (which may have benefits for DR etc.)
Sensor is higher rez which will also help.
No idea about the shutter artifacts, but all appendages are crossed. Popular wisdom is that it's inherent in how the CMOS sensor works. But they're clever folk.

If they speed up the readout time of their sensor than skew will be reduced. Strobe artifacts are here to stay however.
I'm hoping for 14 bit DAC on the chip, hoping that this will mean DR increases even though Graeme once stated it doesn't. ;)

I'd hope for a hell of a lot more than a 14-bit AD. A 14-bit AD means we can't have more than 14 stops of dynamic range... and I'm hoping for more than that.

Geezy Brook. What do you need 14 stops (or more) for?

With 20 stops I could be really lazy and not worry about metering or lighting properly.

Are you sure this is the case? I don't understand how this can be true..

Hi,
I doubt your images will look very interesting.

>20 Stops images look *awesome*. Have a look at this:

Does anyone know of a genlock device that will sync strobes to shutter (in short - has anyone got a solution for this before we find ourselves doing a nightclub scene and no options)
Thx

Hi James
You would imagine it is possible.. I believe since Red has a fast read/reset there will be a period, albeit short, where the strobe would be safe...
Lets keep this question alive to encourage clever minds to create a solution..

Hey man, that pic, is looks like it was taken just a couple of blocks from my apt. on 66th.
At my first look i was thinking how the hell did my footage get posted. haha.

Just as a note,
CMOS does NOT = split frame strobe effect.
DSLRs with CMOS use flash photography.
The Arri D-20, with a larger (vertically) CMOS sensor, works fine with strobes.
The boys at ARRI tell me that there is some heavy processing power performing the readout of the sensor in quadrants, simultaneously.
So before we set a price point for the camera, lets tally up how much the more expensive/ multiple FPGAs (and other hardware required to eliminate this problem) costs, and build that into the price. Let's not get backed into a price point that leaves no room for improvement.
Cheers,
Harry
What about a sensor 3200K native ?
THIS would help!
