Generate Shorts from Long Video
Turn Long Videos into AI-Generated Shorts Automatically
Generate Shorts is Bitcut's most powerful AI feature. Give it a long video (podcast, interview, lecture, vlog) and it automatically finds the best self-contained moments, creates separate projects for each, and adds word-level subtitles. A 30-minute video typically produces 5-10 ready-to-edit Shorts in 2-3 minutes.
How It Works
1. Audio Extraction
Bitcut extracts the audio track from your video. Only audio is sent to the server — your video file never leaves your device.
2. AI Transcription
The server transcribes the audio with word-level timestamps accurate to ~50ms, then corrects any errors automatically.
3. Smart Segmentation
AI analyzes the full transcript and finds segments that work as standalone clips — complete ideas with strong hooks.
4. Quality Scoring
Each segment is scored on 5 criteria: hook strength, coherence, standalone value, completeness, and engagement potential.
Step by Step
Create a project with a long video
Import your long video (podcast, interview, etc.) into a new project. The video should contain speech — Generate Shorts works by analyzing spoken words.
Tap the AI button
In the editor toolbar, tap the AI button and select Generate Shorts.
Wait for processing
A progress screen shows each stage: uploading audio, transcribing, analyzing. Total time is typically 1-3 minutes for a 30-minute video. You can close the app — processing continues on the server.
Review generated Shorts
Bitcut creates a new project for each detected segment. Back in the project list, you'll see the generated projects with suggested titles and quality scores. Higher scores indicate stronger standalone potential.
Edit and polish
Open any generated project to fine-tune. Subtitles are already added. You can adjust trim points, style subtitles, enable face tracking for vertical reframe, and add background music.
What Works Best
Generate Shorts works best with speech-heavy content where each topic segment is relatively self-contained:
- Podcasts — topic transitions make natural clip boundaries
- Interviews — each question/answer can be a standalone Short
- Lectures — individual concepts or examples
- Vlogs with narration — spoken segments with clear points
- Commentary / reaction videos
Quality Scores Explained
Each generated Short gets a composite score (0-100) based on five criteria:
- Hook (30%) — does the first 3-5 seconds grab attention?
- Coherence (25%) — does the clip stay on one topic without drifting?
- Standalone (20%) — can a viewer understand it without watching the full video?
- Completeness (15%) — does the idea feel finished, not cut off?
- Engagement (10%) — is the content interesting, surprising, or useful?
AI Quota Usage
Generate Shorts uses your AI minutes quota. A 30-minute video uses approximately 30 minutes of quota. The free plan includes 30 minutes per month. See AI Quota & Usage Limits for details.
