Video Duration

This block retrieves the duration of video or audio files, useful for planning and conditional logic in media workflows.

Media Duration

What it is

Block to get the duration of a media file.

How it works

The block uses MoviePy to load the media file and extract its duration property. It supports both video files (using VideoFileClip) and audio files (using AudioFileClip), determined by the is_video flag. The media can be provided as a URL, data URI, or local file path. The duration is returned in seconds as a floating-point number.

Inputs

Input	Description	Type	Required
media_in	Media input (URL, data URI, or local path).	str (file)	Yes
is_video	Whether the media is a video (True) or audio (False).	bool	No

Outputs

Output	Description	Type
error	Error message if the operation failed	str
duration	Duration of the media file (in seconds).	float

Possible use case

• Checking video length before processing to avoid timeout issues
• Calculating how many times to loop a video to reach a target duration
• Validating that uploaded content meets length requirements
• Building conditional workflows based on media duration
