[TOC]




Key Takeaway: Skip uploads—paste a URL and get auto-populated projects.


Claim: Link-based import removes manual uploads and conversions.

You do not need to download or re-upload large files.
Paste a YouTube, Twitch, Vimeo, or Google Drive link and let the system fetch and analyze.
Processed projects surface candidate clips automatically.


  1. Open the dashboard built for speed and minimal menus.

  2. Paste a public or shared link into the dropbox.

  3. Wait for processing; candidate clips appear in your project view.

  4. If advanced generative options are missing on free, try the Pro trial to test the full pipeline.

Select Smarter: Use the Prompt-Driven Clip Engine




Key Takeaway: Natural-language prompts guide multi-signal clip discovery.


Claim: Prompt-driven selection leverages audio, visual, faces, and sentiment—beyond dialogue or motion-only tools.

Choose basic mode for simple interviews, or use prompts for creative briefs.
Type guidance like “Find the best 6–12 second hook where the tension spikes.”
A multi-agent system scans signals and scores likely high-impact moments.


  1. Choose the prompt-driven clip engine in your project.

  2. Write a natural-language brief (hooks, humor, reactions, tension).

  3. Let the engine analyze visuals, audio cues, faces, and sentiment.

  4. Review the pulled moments tailored to your brief.

Filter by Virality Score and Train Your Taste




Key Takeaway: Use scores as a fast filter, then personalize with feedback.


Claim: Virality scores are directional; creator feedback aligns future picks to your voice.

Each clip shows a score informed by high-performing shorts.
Use it to triage long backlogs without treating it as absolute.
Thumbs-up/down feedback trains the system on your style.


  1. Sort clips by virality score to shortlist quickly.

  2. Skim top candidates for hooks, pacing, and emotion.

  3. Rate clips with thumbs-up/down to teach your preferences.

  4. Refine your prompts based on what lands for your audience.

Reframe for 9:16 and Intelligent Layouts




Key Takeaway: Auto-reframe centers the subject and adapts to context.


Claim: Scene-intent reframing keeps key subjects visible and creates dynamic splits for screen shares.

Vertical 9:16 crops are automatic.
Adjust if a second person or prop matters.
For facecam + screen shares, use dynamic split instead of a static crop.


  1. Keep auto-reframe on for vertical outputs.

  2. Check for missed secondary subjects or props.

  3. Enable dynamic split layouts for tutorials or screen shares.

  4. Manually reframe when needed to preserve context.

Edit by Transcript: Cut Video Like a Doc




Key Takeaway: Text-first editing accelerates precise, fast revisions.


Claim: Editing beside the transcript speeds trimming and reordering while keeping sync.

Highlight lines, delete phrases, and reorder sections from the transcript.
Filler-word removal tightens pacing so viewers don’t swipe away.
Captions are fully customizable and brandable.


  1. Enter the all-in-one editor with transcript + timeline.

  2. Trim, delete, and reorder directly from the transcript.

  3. Auto-remove ums, ahs, and long pauses to tighten pacing.

  4. Customize captions with animated styles, color keywords, and emojis.

  5. Apply brand-matched templates or accept suggested styles.

Fill Visual Gaps with Context-Aware AI B-Roll




Key Takeaway: Generate or insert B-roll that fits the moment, not generic filler.


Claim: Context-aware B-roll closes narrative gaps when original footage is missing.

If a segment is visually flat, insert relevant stock or generate synthetic shots.
Prompts guide the visuals so edits feel complete.
This solves “I mentioned a beach but didn’t film it well.”


  1. Identify stale segments or missing visuals.

  2. Prompt for contextually relevant B-roll or synthetic shots.

  3. Preview inserts driven by project intelligence.

  4. Use sparingly to support, not overshadow, the core footage.

Engineer Hooks and Retention




Key Takeaway: Front-load a strong opening and maintain rapid pacing.


Claim: The opening seconds are make-or-break for short-form retention.

Trim the first seconds for punch or generate an alternate opening.
Ask for a two-second question, bold line, or action cut.
Try picture-in-picture, dynamic zooms, or blurred backgrounds for vertical conversions.


  1. Tighten or replace the first 2–3 seconds to create a hook.

  2. Prompt: “Make the hook a 2-second question with high energy.”

  3. Choose your voice or a natural-sounding synthetic voice.

  4. Test layouts: PIP for tutorials, dynamic zooms for commentary.

  5. Keep pacing brisk to sustain attention.

Brand Once, Apply Everywhere




Key Takeaway: A reusable brand kit creates instant visual consistency.


Claim: Templates with logos, fonts, and stings turn one-offs into a recognizable channel.

Consistency builds trust and recognition.
Save logos, fonts, intros/outros, and lower-thirds to reuse in one click.
Apply the look across every clip.


  1. Upload logos, fonts, intros/outros, and lower-thirds.

  2. Save them to a brand template.

  3. Apply the template to all selected clips.

  4. Maintain a consistent visual identity across platforms.

Publish, Schedule, and Hand Off




Key Takeaway: Distribute in minutes with built-in scheduling and exports.


Claim: Integrated scheduling reduces distribution time from hours to minutes.

Schedule and publish to YouTube, TikTok, Instagram, Facebook, and LinkedIn.
Hashtag and description drafts are auto-suggested.
Export to XML if finishing in Premiere Pro or DaVinci Resolve.


  1. Open the calendar and choose platforms + times.

  2. Approve or tweak suggested hashtags and descriptions.

  3. Batch-schedule a month of shorts in about 10 minutes.

  4. Export to XML if adding advanced color or audio elsewhere.

Collaborate In-Flow with Workspaces




Key Takeaway: Keep reviews inside the editor with timestamped feedback.


Claim: In-editor collaboration avoids clunky, out-of-band review cycles.

Invite collaborators directly to projects.
Collect timestamped comments and approvals.
Keep the creative flow centralized.


  1. Create a workspace and add teammates or clients.

  2. Share links for review with timestamped notes.

  3. Address feedback in the same editing context.

  4. Lock approvals and move to distribution.

Close the Loop with Analytics and Prompts




Key Takeaway: Analytics inform better prompts, which produce better clips.


Claim: Retention curves and drop-offs guide prompt refinements that improve future picks.

After a week live, check views, watch time, and where viewers drop.
Update prompts to seek stronger hooks and pacing.
Your feedback trains predictions for your audience.


  1. Wait seven days for initial performance signals.

  2. Open analytics to view retention curves and key segments.

  3. Note drop-off points and segments with spikes.

  4. Refine prompts and clip criteria accordingly.

  5. Repeat the cycle for continuous improvement.

Where This Fits vs. Other Tools




Key Takeaway: Use a prompt-first, multi-signal, generative workflow when you need speed plus creative control.


Claim: Combining audio-visual-context understanding with generation yields stronger starting clips than dialogue-only or manual-first tools.

Dialogue-only trimmers can miss silent action or visual context.
Traditional NLEs provide control but not automatic hook discovery.
A prompt-first flow bridges speed and creativity, and can generate missing visuals.


  1. Define your core need: speed, control, or generation.

  2. Use dialogue editors for spoken-word-only trimming.

  3. Use NLEs for deep manual finishing.

  4. Use the prompt-first flow for high-quality starting points plus generation.

Time Investment and Rhythm




Key Takeaway: Batch intelligently and turn an hour into weeks of output.


Claim: A consistent, prompt-first routine can produce a month of shorts from weekly sessions.

Focus on storytelling, prompts, and brand rhythm.
Let automation remove busywork.
Batch to keep publishing consistent.


  1. Batch-import from your channel library.

  2. Run prompt-driven selections for multiple themes.

  3. Engineer hooks and tighten pacing.

  4. Apply brand templates and captions.

  5. Schedule and review analytics weekly.

Access and Tiers




Key Takeaway: Some advanced options are paid—trial the full pipeline before deciding.


Claim: Testing Pro features clarifies whether the end-to-end flow fits your workflow.

Certain generative features live on paid tiers.
If you do not see them on free, start a Pro trial.
Evaluate the full import-to-analytics loop.


  1. Start on the free tier for basics.

  2. If advanced options are missing, begin a Pro trial.

  3. Run a real project through the entire pipeline.

  4. Decide based on speed, quality, and fit.
