Q: What video aspect ratios are supported in the eko platform?

Supported aspect ratios for video based assets

A: Our platform supports any aspect ratio and fits it to a responsive web layout. So there's no "wrong" answer (we even allow switching between different aspect ratios mid-project).

That said we found that for projects that are viewed mostly on mobile, either a 1:1 or a 4:5

aspect ratio looks best.
