Features of Our Short Form Video Maker

9:16 Vertical and 15-60s Timers

Select 9:16 vertical or 16:9 widescreen framing in Video Agent and lock in 15 sec, 30 sec, or 60 sec runtimes so pacing fits mobile feeds.

Grounded in Your Photos and Briefs

Drop up to 20 SKU photographs (JPG or PNG) and 2 campaign brief documents (PDF, PPTX, or DOCX) into the composer so real product shots anchor each scene.

9 Global Subtitle Presets in Studio

Open your storyboard in Studio to pick from 9 built-in subtitle styles, adjust font weight, color, and size, and sync captions across all scenes.

Expressive IV Hooks and AI B-Roll

Combine up to 60 seconds of Expressive IV full-body avatar delivery per video with Text-to-Video and Image-to-Video cutaways that keep viewers watching.

Workflow Inside This Vertical Video Generator

Transform a campaign note or product sheet into a captioned vertical clip inside your browser.

Step 1: Lock In 9:16 Ratio and Duration

Lock the Video Agent canvas to 9:16 vertical framing and choose a 15, 30, or 60 second runtime for your mobile hook.

Step 2: Add Product Shots and Hook Copy

Attach your product or lifestyle images and reference documents, then describe the opening hook, visual tone, and voiceover preference.

Step 3: Sync Global Captions and Export

Synchronize global caption styling across your vertical storyboard in Studio before exporting a crisp 9:16 MP4 file.

Campaigns Built With an AI Social Clip Creator

E-Commerce Launch & Feature Teasers

Turn product photos and key benefits into 30-second 9:16 vertical teasers that grab mobile shoppers in the opening frame.

Educational Micro-Lessons & Quick Tips

Summarize a blog post or industry insight into a 60-second vertical clip with bold step cards and synchronized captions.

Buyer Review & Social Proof Reels

Combine customer review quotes, star ratings, and product close-ups into punchy social proof clips for vertical ad feeds.

Advantages of Our 9:16 Video Maker

Assemble structured vertical videos from real brand assets without complex desktop editing tracks.

Individual Card Edits Without Full Re-Renders

Black-box clip tools force you to regenerate everything when one frame looks wrong; Studio lets you replace a single cutaway or rewrite one hook line independently.

Presenter-Led Hooks or Faceless Voiceover Clips

Start with an Expressive IV presenter in frame one and cut to product B-roll, or delete the avatar layer in Studio for faceless voiceover shorts.

Automatic Text Contrast Over Busy Footage

Studio automatically adapts text color against underlying imagery and syncs 9 caption styles so commuters watching on mute catch every word.

Quick Hook Variations Through Project Duplication

Use Duplicate inside My Videos to test three different opening questions on the same 9:16 body sequence without rebuilding your visual timeline.

Field Advice for High-Retention Short Videos

Lead With the Visual Payoff First

Open with a direct visual result or bold question in the first two seconds before mobile scrollers swipe past your clip.

Match Duration to Funnel Intent

Choose the 15 sec or 30 sec runtime in Video Agent when testing top-of-funnel hooks and single-feature product callouts.

Format Subtitles for Sound-Off Feeds

Apply one of Studio's 9 subtitle presets across all scenes so muted feed viewers can follow every spoken line on screen.

Keep Cuts Between Two and Four Seconds

Keep each scene card between two and four seconds so visual momentum stays brisk throughout a 30-second vertical format.

Respect the Central 9:16 Safe Zone

Keep main titles and captions inside the central 9:16 safe zone so social app buttons and labels do not cover your text.

Mix Avatar Intros With Cutaway Cards

Cap full-body Expressive IV avatar delivery at 60 seconds per video and cut to product B-roll cards for demo close-ups now.
