AI video editor

Multi-track audio mixer

Add background music tracks and voiceovers to screen records.

Scribia is a text-based video editing software for screen recordings. Trim, split, adjust playback speed, add AI zoom and cursor effects, and draw rectangular blur shapes to redact sensitive passwords or credentials before exporting.

Import background music, mix voice audio, adjust volume levels, and sync audio tracks with video scenes. Upload background MP3 audio and manage volume sliders to prevent music from overpowering the spoken tutorial voiceover. Combine multiple audio feeds into a single stereo track during final rendering without losing quality.
