  • 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 :)

Scarlet X Data Sheet

Just checked the Scarlet page on RED.com again and discovered this in the specs section

Isn't 6:1 the lowest compression ratio on Scarlet-X? Has this changed since the announcement or is it just a typo?

At 1k you can shoot 120fps at 3:1
 
Great information, thanks

Could someone please clarify a situation for me please ,

Just wondering why all of these crop factors are derived from a FF35 reference? Like in Cine should it be based on a academy standard format?

if i were to place any 35mm Cine prime on my RED at 4K there shouldn't be a crop factor and the AOV should be relatively the same, right?

Apologies, i'm new to all of this

Regards,
Dean
 
Hi Dean,

Crop Factor and the focal length multiplier is relative to a point of reference. The reason I produced the Data Sheet starting at FF35 is that Scarlet X (and Epic) is compatible with FF35 still lenses and it would be useful to have a point of reference as at 5k you have more of a 1.3x crop factor to start from. Red has also announced in the past that they will develop a FF35 body in the future, so this chart will still be useful. You'll notice there's another chart relative to the APS-C 4k format to assist with practical shooting situations.

Here's the wikipedia article that goes more in depth with examples on what crop factor is and how it can effect your image:

Phil, you are the man!!. Thanks so much, seriously for making these charts man. You have saved so many of us the trouble with these quick reference sheets. I know it is common sense and simple multiplication, but these will be printed and come on every shoot.

Cheers Eric. That's pretty much why I made them too :)

+ 1 !
 
would be great to have update on HDMI and HD-SDI output restrictions. Great guide.
 
2.40

2.40

hey guys, Im sure this has been talked about, but i can't seem to find the answers,
does anyone know if the Scarlet-x has 2.40 ratio mode or will you have to crop later
 
Added to the front page: Deenan's notes on Black Shading:

Deanan said:
My recommendation is to blackshade:
1) upgrading to new firmware
2) big ambient temperature changes
3) long exposure times (longer than ~1/15th sec)
4) very short exposure times (shorter than around ~1/1000th)
5) beginning of a project
6) as often as you feel like

Remember to black shade at default after long/short exposure black shade when your finished.

More convenient/flexible black shading coming later.

S-35 (4perf) = 24.89mm x 18.66mm
S-35 (3perf) = 24.89mm x 13.9mm
35 mm standard film measures 36×24 mm
A 1.6 crop (4K) of a FF35mm is 22.5mm x 15mm

1.6 crop factor lens equivalent

11mm = 17.6mm

RedVolt, RedBrick, and General Battery Consumption

- RedVolt (30Wh) provide about 30-35 minutes of operation time. *
- RedBricks (140Wh) provide around 2.5 hours of operation time. *

* tests done with the 5.0 LCD Touch and Side Handle attached.

What we can take from this is that you get about a bit over 1 minute per 1 watt-hour on battery power. **

**Red has stated that "power management will be coming to the firmware" in the future which should only improve battery life. Also to note, that RedVolt XL batteries (90Wh) are on their way to be used in the QuadVolt Module.

Currently using a high capacity V-Mount battery (225Wh) it is possible to run the Scarlet X for over 4 hours on a single charge.
 
Thanks, Phil. Lots of useful info on the page. Do you have the specific power draw for the Scarlet camera without any accessories being powered?
 
Roy_R, two 225Wh batteries on the BLUESHAPE lunchbox charger (CVS8X) take 200 minutes from minimum to full charge. From 1/4 charge to full would be just over two hours.
