  • Hey all, just changed over the backend after 15 years I figured time to give it a bit of an update, its probably gonna be a bit weird for most of you and i am sure there is a few bugs to work out but it should kinda work the same as before... hopefully :)

Focus....

This is great, I am super excited about the Epic, but since the Scarlet is the one in my budget bracket - I am more blown away by the fact that you used a Scarlet to film the AF clip.
lol

awesome
 
Just got back from a week filming in the Baltic on my EX1R (a great camera for what it is and does), But what great news to read, super excited about scarlet getting ever near, money in the bank ready as soon as it arrives. The EX1R is a great camera but l know its the Scarlet for me as it will have all l need to produce ever better pictures.

To Jim and the team many thanks for bringing the dream ever closer.

Just awesome
 
Jim, when we'll be able to buy the Scarlet ? Please make it before the end of this year ;-)

As I look at this picture, the Lemo connector for the monitor on the Epic's body seems like it would be in the way when you change lenses, etc. What is it like in practice?

People that know their glass know that the 85mm 1.2 lens ( used here ) has an incredibly long focus rotation and a very slow (but accurate) movement... much, much slower than the 1.8.

Regardless... as Jim said the camera was set on critical focus speed, and notice there is no "hunting" around for lock... even wide open at 1.2

But it did hunt. It shot right past the final focus point and then backed up. That's not surprising since all contract-detection approaches do that by their fundamental nature.

This is what makes focus tracking of high-speed subjects very difficult to impossible with contrast-detection systems.

If you want to try a challenging autofocus test, try shooting a subject that is moving toward or away from the camera at between 5 and 20 depths-of-field per second and getting at least 80% of the frames in-focus. Many low-to-middle range dSLRs can do this because they use phase-detection instead of contrast-detection autofocus. This is what will be required if this camera can do what you claim and be used by sports shooters by placing the camera into video mode at some high frame rate and picking the best frames later. No point in doing that if most of your frames are out-of-focus.

Phase detection works off of the mirror reflex system in still cameras similar to a split image rangefinder, not off of the sensor during the shot. Not really applicable to a camera without an optical finder system. The success of AF for a camera like Epic will depend on how well and how fast the AF algorithms can interpret accurate focus at the sensor plane by whatever method. With the high level of processing power Epic has, this may be less of an issue than with contrast AF on a still camera.

Lens data is already in the R3D files according to Jim.

But... it can't currently be accessed.

So the real question should be: will we be able to ACCESS the data, and if so, how?
 
Lens profile database

Lens profile database

Will there be a "generic" Canon/Nikon lens setting for lenses that are not in the database?

Yes, but you should expect that lenses we have profiled would operate faster / more accurately than those that we have not.

I hope Jim answers this more precisely, but I'd be surprised if Scarlet ships in quantity by year's end. I'm seeing a spring 2011 drop date... hope I'm wrong.

In previous threads he stated it would be out this year. Which would make a lot of sense to have it out by Christmas b/c of the market it's designed for.
 
Jim, Jarred or team,

Anyway to plug in an external focus motor to the camera to allow for a wireless FF to be used via the Redmote? Or even using the touch screen to adjust focus in motion mode? This would be a killer feature to have with PL cine lenses as it would eliminate the external receiver that would be mounted onto the camera.

To support that you would need D.C power and a serial communications port for the motor (or the motor controller)

Those features are provided on the Base I/O and Pro I/O Modules .... plus extra I/O and a 2nd viewfinder output.

As for heat.. You should be fine for most of what you are doing. Jim can tell you about a little test we did the other day when we put "Lucky" and "Snake Oil" into a sealed 2 foot heat chamber for 14 hours :)

Holy crap. That's gotta be a first for a camera company. Poor little Lucky, poor little Snake Oil.

The fan is in a sealed tunnel that runs from lower front to out the top. You can pour water down the top and not screw up the electronics. You might have to change the fan though... but that is easy to do. Unscrew 4 screws on the front fan cover and replace the fan (cost is minimal).

Fantastic. Hats off.

Just wondering...is there any chance there could be some sort of shortcut connection between camera and LCD for this setup only, for both Epic and Scarlet, like a "compact setup connector" ?

Good point. I was thinking about it from a cinema or ENG viewpoint. Myopic, as usual ;) How does the Phantom do it? If I'm not mistaken, people use the Phantom on sidelines for big-budget live sports, and everything seems to be focused well.
