When you run:
auto-editor example.mp4 --edit audio:0.05,stream=0You're writing the syntax-sugary equivalent of:
auto-editor example.mp4 --edit "(audio 0.05 #:stream 0)"All the edit methods are listed below:
(audio [threshold] [stream]) → bool-array? Procedure
threshold: Threshold = 0.04
stream: (U Natural 'all) = 'all
Do a one-pass audio filter based on loudest sample in a timebase section, divided by the max value a sample can be.
(motion [threshold] [stream] [blur] [width]) → bool-array? Procedure
threshold: Threshold = 0.02
stream: Natural = 0
blur: Natural = 9
width: Natural = 400
Scale the video to width pixels, convert to grayscale, apply a Gaussian blur of blur amount, then compare the difference with the previous frame.
(subtitle pattern [stream] [ignore-case] [max-count]) → bool-array? Procedure
pattern: String
stream: Natural = 0
ignore-case: Bool = #f
max-count: (U Natural Nil) = nil
When pattern, a RegEx Expression, matches a subtitle line, consider that time the line occupies as loud.
(or operand ...) → bool-array? Procedure
operand: bool-array?
"Logical Or" two or more boolean arrays. If they are different lengths, use the biggest one.
(and operand ...) → bool-array? Procedure
operand: bool-array?
"Logical And" two or more boolean arrays.
