Aspect Ratio Calculator


Ever Wondered What the Correct Resolution Should Be?

A director and editor I knew were creating the final export for a short film.  There was one task left: give the film a cinematic aspect ratio.  They ended up scrambling the Internet for over an hour to find the correct resolution for that aspect ratio.  Worse yet, they had trouble implementing it in the software.

It seemed like such a trivial issue.  This should never be an issue on any project, especially for us Blender-ers.

What Does This Do?

This Blender plugin calculates the aspect ratio of your choice and implements it either for your render or your final composite.

Correct Proportions

Input the ratio, and the add-on applies it to your render's current resolution.  No need to pull out your calculator or Google the resolution!  It makes previewing your animation with a given aspect ratio a snap.

Cinematic Black Bars

Want the cinematic black bars on the top and bottom?  In the compositor, the calculator generates a node setup to give you that perfect look.  And better yet, none of your color data is lost in your composite!  The node setup uses a scene-referred color space, so your render will still look its best.

Choose the Ratio, or Type In Your Own

You can either use one of our presets or input your own aspect ratio, and the add-on will do the calculating for you.  You can focus less on calculating the aspect ratio, and more on getting your animation out on time.
