• If a guess is off, you can regenerate with a better prompt.

1. Highlight the target word or phrase in the transcript.
2. Click Add AI B-roll and select AI-generated B-roll.
3. Review the generated options tied to your keyword.
4. If the match is off, adjust the prompt and regenerate.
5. Insert the best option at the exact moment you need.

Edit, Swap, and Time the Generated Clips

Key Takeaway: You are not locked in—edit prompts, lengths, and positions anytime.

Claim: Prompt edits and micro-timing create on-brand, on-beat visuals.

• Click any B-roll clip to see and refine the original prompt.
• Regenerate multiple options and swap instantly.
• Trim duration and slide timing for precise alignment.

1. Zoom into the timeline for frame-level control.
2. Select a B-roll clip to reveal its generation prompt.
3. Refine the prompt (e.g., “realistic photo of gym with dumbbell rack”).
4. Regenerate to get several new options.
5. Swap in the best fit and trim edges for length.
6. Slide the clip so the cut lands exactly on the spoken word.
7. Keep punctuation cuts tight—often 0.8–1.5 seconds works best.

When to Use Auto vs Manual (and Why)

Key Takeaway: Use auto for speed, manual for sensitive beats or specific visuals.

Claim: Mixing both workflows balances scale with craft.

• Auto B-roll and auto-editing get you 70–90% there fast.
• Manual placement suits nuanced moments and exact imagery.
• Choose the mode based on volume vs precision needs.

1. Start with Auto B-roll to cover the baseline.
2. Identify crucial lines where timing or imagery must be exact.
3. Replace those spots with manual, prompt-tuned B-roll.
4. Do a final pass for trims and micro-timing.

Scale Output: Auto Editing Viral Clips, Auto-schedule, and Content Calendar

Key Takeaway: Find winning moments, batch outputs, and publish on a consistent cadence.

Claim: Systemized discovery and scheduling keep your channels active without daily effort.

• Auto Editing Viral Clips detects emotional beats and high-performing moments.
• Auto-schedule posts clips on your set cadence across platforms.
• The Content Calendar centralizes planning, reordering, and publishing.

1. Run Auto Editing Viral Clips on your long video to surface shorts.
2. Apply Auto B-roll or manual B-roll to the selected clips.
3. Make light brand tweaks to maintain voice.
4. Set Auto-schedule for daily or weekly posting.
5. Use the Content Calendar to reorder, swap creatives, and confirm publish times.

Sound Design Touches That Sell the Cut

Key Takeaway: Small audio moves make visuals feel intentional and professional.

Claim: A subtle swoosh or ambient fill elevates perceived quality.

• Add simple effects at edit points to smooth transitions.
• Keep audio choices minimal and relevant to the visual beat.
• Balance music and voice so dialog stays clear.

1. Identify key cut points on the timeline.
2. Layer a light swoosh or impact on the transition.
3. Add ambient fills to avoid dead air on overlays.
4. Play back and adjust levels to keep speech intelligible.

Common Pitfalls and Fast Fixes

Key Takeaway: Tight prompts and shorter overlays solve most issues.

Claim: Prompt iteration is the quickest path to accurate B-roll.

• If the AI picks a near-miss visual, rewrite the prompt with concrete nouns.
• Avoid hiding the speaker’s face on crucial lines.
• Use split-screen or picture-in-picture when face visibility matters.

1. Spot mismatched visuals and update prompts with specific details.
2. Regenerate and compare options before swapping.
3. Trim overlays to under 1.5 seconds for pacing.
4. Move or shorten any clip that masks key expressions.
5. Use split-screen or picture-in-picture to keep the speaker visible.

A Quick 7-Step Recap Workflow

Key Takeaway: One pass for speed, one pass for precision, then schedule.

Claim: Two focused passes beat hours of manual trimming.

1. Import your vertical and confirm transcript, preview, and timeline.
2. Run Auto B-roll to create a fast cinematic baseline.
3. Play through and mark moments that need exact visuals.
4. Manually place B-roll on selected words or lines.
5. Edit prompts, regenerate, and swap for better matches.
6. Micro-time clips to land on syllables; keep most to 0.8–1.5 seconds.
