  1. #1 Maximum 4:3 for Gemini? 
    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"?

    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/R...i&format=4%3A3

    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?

    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...
