Question: FCPX Triptych / Project Settings

Pardon my ignorance... but any help would be gold right about now.


I'm working on a video to be shown on three projectors. Original project settings were 16:9, but the dimensions have been revised to 4:3 because of the available projectors and 1800 x 600 pixels (if we are creating triptychs within one timeline) or 800 x 600 if we are creating three separate films to be projected simultaneously.


I am creating triptychs (so going 1800 x 600) but when I create triptychs in the new 1800 x 600 settings, I get three squares. Isn't this in conflict with the 4:3 ratio? Shouldn't each triptych appear horizontal?


Apologies again if I am confusing something obvious, but as I am starting again from scratch (and this is my first time creating a video for others) I need all the clarity I can get!


PS: I am using pre-existing footage that is 610 x 360. I know I will lose a ton of color (and content) given the above dimensions and the effect of projection, but anything else I should anticipate?


Many, many thanks!

Hello Luis, you mean to suggest their suggested specs are off? I am going with 1600 x 800, as instructed, but when I split that screen into thirds I get squares. Perhaps I am confused with pixels settings versus project ratio?

Now you wrote 1600x800, but I suppose you still meant 1800x600.


The math is trivial - assuming square pixels.


600x600 is a square

Three of these side by side give you 1800x600.

This will make the total image with an aspect ratio of 3:1 (3 squares, i.e. 3 times 1:1)


800x600 is a 4:3 aspect ratio.

Three of these side by side give you 2400x600.

This will make the total image with an aspect ratio of 4:1 (3 times 4:3)


You have to talk to the people you are doing this for and clarify what they need/want.
