Quick answer
Blender video editing uses a timeline-based editor for clips, audio, previews, transitions and exports. It is useful for users who want basic editing inside the same 3D software environment.
Timeline editing
The video timeline lets users arrange clips, trim footage, preview edits and organize simple video projects.
Audio and preview
Audio tracks and waveform preview help align timing, cuts, animation renders and final sequences.
Export workflow
Export settings control resolution, format, frame rate and final video output.
