Method: Timecode.parse

Defined in:
lib/timecode.rb

.parse(spaced_input, with_fps = DEFAULT_FPS) ⇒ Object

Parse timecode entered by the user. Will raise if the string cannot be parsed. The following formats are supported:

  • 10h 20m 10s 1f (or any combination thereof) - will be disassembled to hours, frames, seconds and so on automatically

  • 123 - will be parsed as 00:00:01:23

  • 00:00:00:00 - will be parsed as zero TC
