Alexa Mini - 4:3 with 1.5x anamorphic de-squeeze

[Jake Ward]

I'm using 1.5x anamorphic lenses with my Alexa Mini in 4:3 mode, but I cannot find a way to sets a 1.5x de-squeeze option.
There only seems to be 1.3x and 2x de-squeeze options. Is there a way to load in or set custom de-squeeze modes?

1.5x has been chosen for a 2:1 delivery.

Thanks in advance.

Dear Jake,

ALEXA Mini does not support a 1.5x de-squeeze.
Please use an external monitor for de-squeezing and record MXF/ARRIRAW Open Gate.
Depending on the illumination of the lens... 2936x2202 is the photosites count you'll need for 2.0 with an 1.5 squeeze.
2202*2/1.5=4404/1.5=2936

As 4:3 is only a metadata crop you will not loose anything by shooting Open Gate, the data load is identical.

Cheers,
Jan
