version c but maybe with a few tweaks,
switch record settings with the white balance,
switch the prefs & utilities with black balance

that way all camera settings are across the top where not used as much and then the right hand side is all the buttons used while shooting

different question how are we going to set white balance with the kelvin temp rather than custom in the future, is it from that button?

so i tried my first save a raw file today and it froze and stoped pretty early on i looked at the file on the card and its 4.29 gb do you know why it may have stoped saving and froze? it saved  the h264 just fine before that

How long did it take to freeze approximately? There's currently a limitation with FAT32 formatted cards, they can't handle files over 4GB, if the file you saved was larger that would explain the problem. You can try an EXT3 formatted card if you want to save larger files. exFAT and NTFS support is in the works so this will be solved.

At least 5-10minutes it was saving at 3-5fps I think

hey guys so i have trouble viewing the screen on the chronos for focus or exposure or flaming due to bright sunlight while shooting sports and action.
we don't have hdmi out yet for using a highbright moniter or viewfinder so i got this Grid 5.0 viewfinder for the screen on the back
i got my for 175$ on reduser brand new but second hand
installed it yesterday and its pretty awesome
the frame needs slight trimming to not hit the jog dial but thats easy with scissors. then it attaches 3m sticky
the loupe attaches to that via magnets
so far stoked way better for viewing outdoors, hightly recomend, easy to take off for touchscreen functions, but more jog dial control would be nice
here is link to website https://www.gridaccessories.com/products/grid-5-0-viewfinder/

Advantages of using the speedbooster on chronos camera,
reduction in focal length by 6.4x when using adapted lenses,
allows use of usb power to adapter to power image-stabilizer on canon lenses even when not connected to camera or on dumb mount
allows use of usb power to control electronic aperture on canon lenses via jog on the adapter

I dont think i agree about making the timeline horizontal its way better where it is for right handed one handed control, i just played around with it and keeping it where it is seems better, but still think right and left arrows even with a vertical timeline is still way more intuitive
Hm, that's two votes for left-and-right, now. Maybe I will have to change it back. ???

I'm not entirely sure the interface should be designed to be one-handed at all. Playing around with it, trying to use the interface when I'm just holding the camera unsupported in my right hand, I have serious difficulty interacting with the thing. It's pretty hefty.  I need it propped up by my left hand, or screwed onto a tripod or something before I can use it. In both cases, I can pretty easily access the bottom few centimeters of the screen.
i am holding the grip like you do but can have support of a tripod or a left hand for camera weight and the right thumb controls jog and all the touch screen funtions from that one thumb, scroll bar way easyier when vertical on right side to set in and out points fast


Could you show me how you were holding it? :D That'd be really useful.

Thanks!
sorry i think my post got deleted and it just showed the quote,
so im not holding and operating the camera with just one hand, usually its supported with the left hand on the left side of thecamera body or lens focusing  and the right hand it holding the right side and the right thumb does all of the touch controls and jog dial. easy for suporting the camera and setting in and out points fast before the next action

also on a tripod the right hand can do all the setting of in and out and save while the left is left to relax or hold your beer or control the screen if you really want to.
video showing this.

yeah i may get one on the angle and use that to measure the angle for nathan to correct and then get another one with that correction, unless you want to measure the angle on yours?
stoked

Yes, the XL works perfectly. The Ultra also worked but the XL is better IMO.

In both cases you would need to play around with the spacers Nathan supplies to get the back focus correct.

Here are a couple of pics:


sick that is what i thought, just wanted to make sure because that adapter was $$$
is your adapter a little rotated off of center? if so is it possible to get it to sit straight so the lens isn't rotated, for when i use a large lens with a non rotating tripod collar?
thanks

We actually just prototyped this, not with a BMPCC speed booster however, just a low cost Chinese one, but it works very well. Speed boosters that have an MFT mount seem to be the most common, but it's not possible to convert MFT to C mount. MFT to CS mount is just possible, but no one makes that adapter. We're going to custom make our own once we have some time to design it.
great to see others were thinking the same thing! keep me up to date on the progress, or if you need help i do mechanical engineering work mainly solidworks
hey john are you sure its the speedboster XL that your using, i just bought that one and Nathan said that one doen't work.
wondering which one you have?
thanks
