AI Editing with CapCut
Ch13 AI Editing with CapCut: Complete Workflow from Raw Clips to Final Cut
Editing is the process that transforms all your AI-generated materials from raw ingredients into a finished product. It is also the single biggest determinant of how your short drama feels to watch. CapCut has evolved from a simple mobile editor into a full-featured AI editing platform. This chapter covers its core AI capabilities and walks through the complete workflow from asset organization to final export.
CapCut AI Feature Overview
Auto-Caption (Speech Recognition)
The most-used AI feature: Text → Auto Captions → Start Recognition. CapCut automatically transcribes your voiceover into time-aligned subtitles. Accuracy exceeds 95% for Mandarin/English. Always proofread for proper nouns and numbers.
Auto Beat Detection
Select your BGM track → Right click → Auto Beat Detection. Yellow markers appear on the timeline. Align your edit points to these markers to create music-driven rhythm cuts.
