Step 3

Principle & pipeline
The merge engine builds a single timeline, aligns audio, and exports once to keep clarity and sync.
Timeline assembly
Clips are stitched in order with frame-accurate cuts so motion flows naturally.
The renderer keeps your chosen aspect ratio and prevents extra transcodes that could soften the image when joining videos for TikTok, Reels, Shorts, or YouTube.
Audio alignment
Audio tracks are leveled and matched to the timeline to avoid jumps between clips.
A single export keeps voices and music in sync. Preview before downloading to confirm pacing across every segment you merged.
