Limits. Set by your plan.

Overlays are images or videos given as inputs. Text and subtitles use the fonts on the Fonts page of the docs.
Subtitles come from an SRT or WebVTT input of at most 1 MB; the tags and styles in the file are removed, so every cue is plain text.
Inputs are public http or https URLs, or completed private uploads up to 100 MB and your plan’s input limit. Outputs have signed download links. A job names up to 16 input and 16 output files.
