🎵 Smart Audio + Playlist/Live Video Merger

Note: Camera/Screen capture requires HTTPS (or http://localhost). Browser permissions required.

If you want “video-only crop”, leave audio empty and use Manual Seconds.

Timeline defines the final render length. Last clip is cropped precisely to end at the boundary.

Playlist mode plays clips in order, then repeats as needed to fill the timeline. Single mode uses the first selected clip and loops it.

If camera labels are blank, click Refresh (it will request permission once), then refresh again.

Tip: Start Webcam first. JPG uses “quality”; PNG ignores it. “Scale width” helps speed & file size.

You’ll be prompted to choose a screen/window/tab. If the share ends, the preview stops automatically.
