Video Loop

This block repeats a video to extend its duration, either to a specific length or a set number of repetitions.

Loop Video

What it is

Block to loop a video to a given duration or number of repeats.

How it works

The block uses MoviePy's Loop effect to repeat a video clip. You can specify either a target duration (the video will repeat until reaching that length) or a number of loops (the video will repeat that many times). The Loop effect handles both video and audio looping automatically, maintaining sync. Either duration or n_loops must be provided. The output is encoded with H.264 video codec and AAC audio codec.

Inputs

Input	Description	Type	Required
video_in	The input video (can be a URL, data URI, or local path).	str (file)	Yes
duration	Target duration (in seconds) to loop the video to. Either duration or n_loops must be provided.	float	No
n_loops	Number of times to repeat the video. Either n_loops or duration must be provided.	int	No

Possible use case

• Extending a short background video to match the length of narration audio
• Creating seamless looping content for digital signage
• Repeating a product demo video multiple times for emphasis
• Extending short clips to meet minimum duration requirements for platforms
