How do I merge multiple video clips into one continuous video?

Upload two or more video clips, arrange them in your preferred timeline order, choose output resolution and framerate, and click 'Merge Videos' to combine them into a single file.

Can I merge video clips with different resolutions (e.g. 720p and 1080p)?

Yes. The merger automatically scales and centers each clip onto a standardized canvas, ensuring smooth visual transitions without letterboxing distortion.

Can I merge videos with different framerates?

Yes. The engine standardizes frame presentation timestamps (PTS) to a target frame rate (e.g. 30 FPS or 60 FPS).

How many video clips can I combine?

You can combine up to 20 clips depending on your device's available browser memory.

Does merging keep audio from all clips?

Yes. Audio streams from each clip are sequentially concatenated in exact chronological order.

Are videos uploaded to a cloud server?

No. All concatenation runs in your local web browser memory via HTML5 Canvas and Web Audio APIs.

Can I rearrange the order of video clips before merging?

Yes. Drag and drop or use arrow buttons to reorder clips before compiling.
