Maximum 4:3 for Gemini?

[Brian Caldwell]

My apologies if this is obvious, or has been discussed before, but the online technical specs are unclear to me on this point. The maximum format size is 5120 x 3000 pixels, or 30.72mm x 18mm. Other than shooting full 5k and then cropping, is there any other way of getting full-height 4:3? (e.g., 4000 x 3000 pixels, or 24mm x 18mm)?

It appears that 5K 1.7:1 and 5K 6:5 are the only current ways to get maximum height out of the Gemini sensor.

Correct me if I'm wrong but according to the 7.1 Beta firmware release:

v7.1 Release Notes:
* Added Sensor Flip/Mirror Scan Direction for DSMC2 MONSTRO 8K VV
* Added 5K 4:3 and 5K 4:3 2x ANA support to EPIC-W 8K S35, DSMC2 5K S35, DSMC2 8K S35 and DSMC2 8K VV

I have the beta firmware on an Epic-W Helium

5K 4:3 is 5120 x 3840
4.5K 4:3 is 4320 x 3240
4K 4:3 is 3840 x 2880

I'm not sure what that means for Gemini, but I can't get anything with 3000 pixels height. If 5K 4:3 on Gemini utilizes the full height of 3000, then it's going to be 4000 x 3000, which is between 4K and 4.5K on Helium. So now we have a discrepancy with naming conventions, which is awfully confusing to say the least.

If "5K 4:3" is 5120 x 3840, what is "5K 4:3 2x ANA"?

 

[Dan Kanes]

Should desqueeze to 10,240 x 3840

Or with a squash to 5120x1920

Brian, come visit me in Burbank and try my Gemini some time! We can have lunch.

Here are gemini 4:3 formats - http://phfx.com/tools/REDFormatKey/REDFormatKey.cgi?camera=REDEpicW5KGemini&format=4:3

Do the 4:3 formats crop the sensor on epic-w helium? Is there still a benefit to shooting anamorphic on gemini vs helium after the latest firmware?

 

[Nick Gardner]

Gemini chip is taller, giving you more FOV on anamorphics.

I think Phil's tools page still need to be updated to the latest 5K 4:3 and 5K 4:3 ANA resolutions available...
