Render Pipeline

Hyperclip composes and renders your final videos using a multi-layer pipeline.

​

How it works

​

Composition

Each layer of your video (base footage, captions, audio) is rendered and synced together automatically. Composition layers:

1. Base video — The main video content from your flow
2. Caption overlay — Styled text captions synced to audio timestamps
3. Voiceover track — Text-to-speech audio layer
4. Background music — Music track mixed at lower volume

​

Rendering

Rendering is handled server-side for fast, parallel video encoding:

1. The composition is rendered frame-by-frame
2. Audio tracks are mixed and synced
3. The final MP4 is produced and stored

​

Performance

Rendering typically takes 30–120 seconds depending on video length and complexity. Longer videos with multiple audio layers and caption effects take longer.

​

Concurrency

You can run multiple renders at the same time. If the system is under heavy load, you may see a “too many renders” message — just wait a moment and try again.
