Frequently Asked Questions

What is video composition?

Video composition is the process of combining multiple video clips into a single output. You can add background audio, burn in subtitles, and apply transitions to create a polished final video.

How do I compose videos with audio online?

Upload or link your video clips in order, add an optional background audio URL, and submit the job. VideoComposer merges the clips and mixes in the audio, then delivers a downloadable MP4.

Can I add subtitles when composing videos?

Yes. Provide a subtitle file URL (SRT or VTT format) and the tool will burn the subtitles directly into the composed video output.
