# Video Loop
|
|
<!-- MANUAL: file_description -->
|
|
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
|
|
<!-- MANUAL: 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.
