Test it

Using "remotion-multimedia". Find the duration of an audio file from a public URL.

Expected outcome:

A typed asynchronous helper creates a Mediabunny URL source, computes the duration, and returns the result in seconds.

Using "remotion-multimedia". Check a local video's dimensions before rendering.

Expected outcome:

Use a file source for the supplied local file.
Read the primary video track.
Return its display width and display height.

Using "remotion-multimedia". Inspect a video stored in Remotion's public directory.

Expected outcome:

Resolve the asset with staticFile, pass the resolved path to the helper, and use the returned duration for composition timing.

What You Can Build

Match Composition Timing

Read source footage duration before setting a Remotion composition length.

Validate Uploaded Media

Check browser-selected video dimensions before accepting an upload or selecting a layout.

Catalog Media Metadata

Extract durations from local audio and video files in a Node.js or Bun workflow.

Try These Prompts

Read Audio Duration

Show me how to get the duration of an audio URL with Mediabunny in TypeScript.

Read Video Dimensions

Create a Mediabunny helper that returns a video URL's display width and height. Include handling for a missing video track.

Use Remotion Assets

Adapt the video duration helper for a file in Remotion's public directory using staticFile.

Support URL and Local Sources

Design reusable TypeScript utilities for audio duration, video duration, and dimensions. Explain UrlSource and FileSource choices for browsers, Node.js, and Bun.

Best Practices

Use staticFile for assets stored in a Remotion public directory.
Check that a primary video track exists before reading its dimensions.
Choose UrlSource for URLs and FileSource for caller-provided local files.

Avoid

Do not assume every media input contains a video track.
Do not treat instructional retry settings as complete production network policy.
Do not use these metadata helpers as a substitute for media validation or transcoding.
