Ready. Import videos, run smart montage or edit manually on the timeline.

This tool is built around automatic video editing: import source clips, run smart montage, create Shorts drafts, and then quickly clean the result on the timeline if needed.

The auto tools focus on removing long quiet or static moments while keeping speech safer from unnecessary cuts. Manual tools are still available for precise splitting, deleting, fade transitions, previewing 16:9 or 9:16 output, and exporting the final MP4.

Automatic video montage and smart Shorts creation in the browser

Smart Auto Video Editor & Shorts Maker is positioned as a lightweight automatic montage tool for creators who want to spend less time cutting footage by hand. Users can import multiple videos, build one combined timeline, run smart auto-montage, generate Shorts drafts, and then fine-tune the result manually.

The automatic tools analyze audio activity and basic frame dynamics to find long quiet or visually static zones. The goal is conservative editing: preserve speech, avoid chopping phrases, remove obvious dead sections, and prepare cleaner drafts for YouTube videos, Shorts, Reels, or TikTok-style publishing.

Manual timeline controls remain available for final cleanup: split clips, delete unwanted pieces, stretch clip ends, preview video and audio tracks, apply fade-to-black transitions to all cuts, choose 16:9 or 9:16 output, and export a finished MP4. Processing runs in the browser with FFmpeg WebAssembly, so the PHP hosting mainly serves the interface while rendering happens on the user device.

Frequently asked questions

Does this editor upload my video to the server?

The tool is designed to process selected videos locally in the browser using FFmpeg WebAssembly. The PHP hosting serves the page, while rendering happens on the user device.

Can it create automatic Shorts drafts?

Yes. Smart Shorts can create several Shorts-ready timeline drafts. The selected 9:16 mode is kept: center crop or blurred background.

What transition is supported?

The editor supports a simple fade-to-black transition between timeline clips. You can turn the fade on or off and choose a transition length from 1 to 5 seconds.
