  • 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 :)

I see build 12 has a timelapse function with built-in intervalometer with 1 to 1024 seconds between shots. Has anyone explored this feature? This is a silly question, but I'm just wondering how it works: say you set up a 10 second delay, in this mode. Now when you start recording does it take the first shot immediately, or wait 10 seconds before taking the first one?
 
If the first second is important than you should shoot high speed not interval right? But it would be nice to know just for fun. LOL. I like useless facts too.

In a worsed case you just need to press the record button 10 seconds early and you are done.

Hehe, seriously, we should test this. I have to much on the list to test, step by step - and we have two regular shootings next two weeks, but I'll try to figure it out.

Timelapse is indeed very interesting.

i tried it yesterday .. i really didn't pay attention if it recorded the 1st frame when i pressed record or waited ? anyway i did 1 sec intervals ...it did work ..

also tried a ramp ..and it worked ...

don't know if anybody else has mentioned it ... but on camera playback of any clip you go thru it manually frame by frame, forward or backward ..

I had something different in mind. Say you wanted a R3D file with just a single frame (eg. using it as a stills camera) and you wanted that frame not to have motion shake from physically pressing the record button. Then you'd want a short delay first, and then take the frame. Not that it would kill me to have two frames instead of one, I guess.

Then I might instead use Varispeed mode with 1 fps as the frame rate. Then start / stop the camera from a GPI trigger..
 
For some timelapse recordings, 1s interval can be too long.
Could you please add smaller intervals like 1/2 second and 1/4 second ?

Oh wait, or is this already covered by the "varispeed" feature ?

Thanks,
Nils.
 
this may be a Stuart question but what I would like to do is setup a time-lapse on one Red and have it also trigger a second Red at precisely the same moment. Is this possible to do right now between two Reds and a trigger cable?
Thanks!

Yes that should work - just trigger both camera's GPI inputs from a common cable.

Yes, turn Varispeed on and select 2 fps or 4 fps record frame rates. Then trigger the record start / stop manually or by a GPI input.

Another option is to turn on TimeLapse and select One-Shot record then trigger each frame capture by the GPI input.

Hi Stuart,

Thanks for this info. Can you also GPO a signal to a device that triggers stepper motors between shots? If so, would that be a 12v signal?

Thanks,
Dale

I'd like to know if there is the ability to hold the shutter open for longer exposures.

Yes we can, up to 1 second. We added longer exposure times into the the User Interface in Build 12, but its not operational yet (maximum at the moment is 1/24th sec). If you need an exposure of longer than 1 sec, then we would need to use a different technique.

Thanks Stuart.
I guess I should clarify just to make sure...I was hoping the triggering mechanism for the second Red cam would come from the first Red cam. (in timelapse mode) Can that be done?
Thx!

Yes, I often use exposures of 17 seconds or longer, so that would be great.

Thanks for the answer Stuart,

If ever possible down the road 1-2 min exposure would be gladly welcomed. Shooting stars streaking through the night sky as the earth rotates would be great to capture on the Red.


Method
 
Regarding triggering the camera and Varispeed, is this something on the list to control that external, like interfacing it with the Cmotion Lens Control System (www.cmotion.at)
Cmotion is in my opinion the most versatile Wireless Lens and Camera Control System arround and it would be great if Cameracontrol would be also possible with red camera (e.g. Ramping with Iris/Shutter compensation,..)

Yes there is a GPO signal available. Its 3.3V. See Build 12 Ops Guide ... pages and 42 and 56
