VideoTrim - ComfyUI Built-in Node Documentation

This node cuts a video to a chosen time window by setting a start time and a duration. It also offers a strict mode that raises an error when the requested duration cannot be achieved.

Inputs

Parameter	Description	Data Type	Required	Range
`video`	The video to trim.	VIDEO	Yes	—
`trim`	Trim window using start/end frames. The window is converted into a start time (in seconds from the beginning of the video) and a duration (in seconds). When both the start time and the duration are 0, the video is returned without any trimming.	VIDEO_EDIT	Yes	start_time: >= 0, default 0 duration: >= 0, default 0
`strict_duration`	If True, when the specified duration is not possible, an error will be raised. (default: False)	BOOLEAN	No	true false

Note: The trim duration must be >= 0; negative values raise an error. The requested trim window must fit inside the source video. If the trim cannot be applied, an error is raised that reports the source duration, start time, and target duration.

Outputs
