Hmm... This reminds me of the school in the TV show "Heroes" where Claire the Cheerleader first gets attacked. Interesting. :ph34r:

David, thanks for sharing your experiences on-set. Your threads are an invaluable resource for us all.

I agree, it does, lol...

David,
How where these frames graded and what system do they plan to finish the film on, SCRATCH?

BTW, awesome work, looks great!

I just ran the shots through Photoshop and did a slight increase in contrast and saturation, though for the most part, they come through Red Alert more or less looking correct. I've been getting select 4K TIFF's at night from out data wrangler Eric Yu. I'm shooting with the camera's saturation level boosted from "1" (normal) to "1.5" so that it tracks as metadata for our dailies. Though the boosted color does cause some odd artifacts to appear now & then on the monitors and in the TIFF's, like some faint yellow blotches in skintones.

No decisions have been yet as to where the final color-correction and film-out will take place.

David, I noticed your saying "I did discover that no matter what frame rate or shutter speed I tried to select, there is a limit of 1/24th of a second for the longest exposure time per frame, so you can’t just go to 8 fps, for example, with the shutter off, to get nighttime landscapes exposed at 1/8th of a second per frame."

Had you been able to accomplish slower frame rates with longer shutter speeds in past builds? I thought I had remembered reading of the possibility of shooting up to 2 fps with basically a 1/2 sec. exposure time.

We just finished a film for our Museum that was almost half shot at between 2 and 8 fps with accordingly long exposure times on our trusty HVX200 and would sorely miss that possibility.

Many thank for your very generous posts,
David

I know that in earlier builds the longer shutter speeds were not enabled. Supposedly in Build 16 they are enabled but only accessible through the "timelapse" mode: According to the Build 16 (v3.2.5 released) ops guide at http://www.red.com/support on p. 31:

Speed: Specifies the shutter speed to be used during Timelapse. This control is the same as is available in the Shutter menu, but it provides access to additional shutter speeds that may be used in Timelapse recording. The additional exposure time presets are 1/2, 1/3 1/4, 1/6, 1/8, 1/12, 1/16 second.

jbeale,

thanks very much. That information puts my mind to rest.

My understanding is then that RED, understandably, view 2 fps at 1/2 sec. exposure as a variation of timelapse. Makes perfect sense.

Thanks again,
David

I hadnt played around with the timelapse feature, so the additional shutter speeds there are great. But that doesnt solve shooting at 8fps and getting a 1/8th shutter. The fastest the timelapse can do is 1fps. So there is a gap there that would need to be filled. The relative shutter may do the trick.

[jbeale]

Note, I have not used a Build 16 camera, I'm just reading the manual... based on that, my understanding is that in Timelapse Mode using the internal intervalometer, you can shoot only 1 fps max (inter-frame delay goes from 1024 seconds to 1.0 second). You can also use an external GPI trigger mode, but that may be limited to something like 6 or 8 fps, I'm not sure.

The "VARISPEED" mode covers the range from 1 fps up to the maximum framerate, but apparently without the longer shutter times (?).

Since the hardware is apparently capable of it, I assume eventually the firmware will be updated to allow intervalometer mode to shoot faster than 1 fps while retaining shutters slower than 1/24, and/or enable longer shutters in Varispeed mode.

[David Wilson]

Hmmmm... I guess my mind just came out of rest again and will have to wait for future upgrades.

I do love those slow fps/long exposure possibilities.

Many thanks for the input.

To get 1/8 sec shutter -
Set shutter mode to relative.
While at 24fps, set your shutter speed to 1/24.
Go to Varispeed and set framerate to 8fps.

The shutter will follow the framerate relative to the 1/24 you were on at 24fps.
