The Video Slice node allows you to extract a specific segment from a video. You can define a start time and a duration to trim the video, or simply skip the beginning frames. If the requested duration is longer than the remaining video, the node can either return what’s available or raise an error.

Inputs

Parameter	Data Type	Required	Range	Description
video	VIDEO	Yes	-	The input video to be sliced.
start_time	FLOAT	No	-1e5 to 1e5	The start time in seconds from which to begin the slice. A negative value will skip frames from the beginning of the video. (default: 0.0)
duration	FLOAT	No	0.0 and above	The length of the slice in seconds. A value of 0.0 means the node will return all video from the start time to the end. (default: 0.0)
strict_duration	BOOLEAN	No	-	If set to True, the node will raise an error if the requested duration cannot be met (e.g., if the slice would go beyond the end of the video). If False, it will return the available video up to the end. (default: False)
