How to edit a video in your browser

A browser video editor can cover the work creators do most often: trim a recording, combine media, add captions and graphics, balance sound, and export. R3 Studio keeps the active project on your device for responsive editing and can privately back up paid projects.

WORKED EXAMPLE

Turn one recording into a finished tutorial

A camera recording, a cleaned voiceover, and a title idea

A trimmed video with linked audio, an opening title, captions, and a balanced music track

1. Start with a project and import media

Create or open a project, choose Assemble video, and import the camera recording, images, or audio you need. R3 Studio stores video source files and working data in private browser storage on the current device.

Use descriptive filenames before importing. The media panel shows the available assets, while the timeline holds the clips that will appear in the exported result.

2. Arrange and trim the timeline

Add the main video first. Its camera audio is linked by default, so moving or changing the speed of the video keeps the matching audio aligned. Delink only when you need to edit them independently.

Drag clips to change their timeline start. Use the clip edges for a visual trim, or enter timeline start, duration, and source start in the inspector when you need an exact value. Timeline zoom gives short edits more room without changing the project.

3. Add titles, captions, and visual guidance

Place text and captions above the main video. Position and resize them directly in the preview, then use the inspector for typography, color, timing, and exact values.

Shapes can highlight an area, draw an arrow toward an important control, or blur sensitive content. Add motion keyframes when the graphic needs to follow movement over time.

4. Mix and review the sound

Keep narration intelligible before adding music. Use track and clip volume, fades, mute, and solo while comparing the camera audio, edited voiceover, and music.

Play across every cut and transition. Headphones make clipped words, abrupt fades, and competing music easier to notice before export.

5. Export and keep the source project

Choose an aspect ratio and resolution that match the destination. Browser export uses the codecs and hardware capabilities available on the current device, so preview the exported file before publishing.

Keep enough free device storage for temporary export files. Creator and Studio media can be backed up privately, but the downloaded export remains the copy you can upload to a publishing service.

Make room for your next take.

Put this guide into practice with a short recording. Your scripts and audio stay on your device.
