DurationControl
Settings for integer-second duration normalization. When this preprocessor is present, the output duration will be adjusted to an exact integer-second boundary. If the input is within the trim threshold of an integer second, trailing frames are dropped. If within the compression threshold and less than 500ms over the previous integer second, the output is sped up slightly. Otherwise, black frames are padded to the next integer second.

Required. Denominator of the maximum allowed compression ratio.
Required. Numerator of the maximum allowed compression ratio, defined as overrun divided by target duration. For example, numerator 5 with denominator 100 means max 5% compression. Set to 0 to disable compression entirely (only trim or pad will be used).
Maximum number of fractional milliseconds past an integer second that qualify for the trim path (frame dropping). Default is 0 (trimming disabled).
