Limits and policies

Know the boundaries before you ship

Video processing workloads vary widely. These guardrails keep the platform stable while you scale.

Plan-based usage limits

Credits and plan tiers determine processing time, concurrency, and maximum upload sizes. Check your dashboard for the latest limits.

Anonymous usage caps

Browser tools include daily limits to prevent abuse. Create an account to unlock higher limits and API access.

Supported formats

Inputs must be in supported video, audio, image, or subtitle formats. Use the tools to validate before sending jobs.

Async processing windows

Longer videos take more time. Use webhooks or job polling to keep your app responsive.

Fair-use rate limits

API endpoints enforce fair-use rate limits. If you need higher throughput, reach out to the team.

Frequently Asked Questions

Everything you need to know about VideoComposer

VideoComposer is a free online video composer that lets you merge, trim, convert, and watermark videos directly in your browser — no downloads or signup required. It also provides a REST API so developers can automate video composition at scale.

A video composition API lets developers programmatically merge, trim, overlay, and convert video files via HTTP requests — without a desktop editor or manual steps. VideoComposer provides a REST API that handles all core video composition operations, returning processed files asynchronously.

Send a POST request to the relevant endpoint (merge, trim, convert, or watermark) with your video file URLs and parameters. The API queues the job and returns a job ID. Poll the status endpoint or configure a webhook to retrieve the finished video URL when processing completes.

Browser tools accept MP4 and WebM inputs. The converter outputs MP4, WebM, or GIF. The compose tool supports MP3 audio and SRT/VTT subtitle files. Use the /video/validate API endpoint to confirm format compatibility before submitting a job.

Yes. VideoComposer is free for browser-based tools with no account required. Anonymous users can run up to 5 jobs per 24 hours. Paid credits-based plans are available for higher volume and full API access — no mandatory monthly minimum.

FFmpeg is a powerful command-line tool that requires installation, technical expertise, and manual scripting. VideoComposer wraps the same FFmpeg-based processing in a browser UI and a clean REST API — no server setup, no CLI knowledge needed. Use VideoComposer to get FFmpeg-quality results without the complexity.

Each credit equals one second of processing time (rounded up). Jobs deduct credits based on actual processing time. Typical usage in the docs: trim ~10 credits/min, convert ~20 credits/min, compose ~15 credits/video, overlay ~15 credits/min.

Yes. You can configure webhooks per API key to receive job completion callbacks. If you prefer, you can also poll job status; browser tools can send email notifications when a job finishes.
