Preview on mobile — see your work on the screen it's made for
TL;DR: Every generation automatically sends to your phone. Scan the QR code once, add to home screen, and you have a dedicated modelBridge preview app that always shows your latest generation — with safe zone overlays for TikTok, Instagram, and YouTube. No cables, no AirDrop, no manual file transfer.
Why preview on mobile matters
Section titled “Why preview on mobile matters”A social ad that looks great on your Premiere monitor can feel completely different on a phone screen. Subjects get cropped. Text sits outside safe zones. Motion that reads well at 1920×1080 looks chaotic at 9:16.
The only way to know how a generation actually feels for its intended audience is to see it on the device they’ll watch it on — before it goes to the timeline.
First-time setup — scan once, done forever
Section titled “First-time setup — scan once, done forever”After your first generation completes, a Preview on mobile row appears at the bottom of the preview panel.
Setup steps:
- Click QR in the preview row to expand the QR code
- Scan with your phone — opens the modelBridge preview page in your browser
- Tap Share → Add to Home Screen
- Open the modelBridge app from your home screen
That’s it. The QR code is tied to your machine — the same URL forever. You never scan again. Every future generation on this machine automatically appears on your phone within seconds.
What you see on your phone
Section titled “What you see on your phone”The mobile preview is a PWA — it installs like a native app, runs fullscreen with no browser chrome, and polls for new content every 5 seconds.
For every generation:
- Video autoplays muted and loops — tap for playback controls
- Images display full-width, centered
- Multi-image results show as a swipeable carousel
- Audio shows as a full player with progress and duration
- Metadata card shows model name, category, and time since generation
For Dual Mode generations: Both model results appear as labeled slides — swipe to compare on the actual screen size.
Safe zone overlays
Section titled “Safe zone overlays”Tap the Safezone pill at the bottom of the screen to choose a platform overlay:
- TikTok — shows the safe area for TikTok’s UI elements
- Instagram — shows Instagram Reels safe zones
- YouTube — shows YouTube Shorts safe zones
The overlay is semi-transparent and persists across reloads. Toggle on while reviewing, off to see the full frame. Essential for Meta ads, Reels, and any vertical content where subject placement matters.
The workflow
Section titled “The workflow”Standard workflow:
- Generate in modelBridge as normal
- While the preview plays in Premiere’s Source Monitor — glance at your phone
- The generation is already there, autoplaying
- Tap Safezone to check subject placement against platform UI
- If it looks right on mobile — import to timeline
- If not — adjust and regenerate
No extra steps. No manual sends. The mobile preview happens automatically after every generation.
Working on Meta ads and mobile-first content
Section titled “Working on Meta ads and mobile-first content”For Meta ads, social content, and any vertical format — run this check before every import:
- Generate at the right aspect ratio (9:16, 1:1, 4:5)
- Phone preview appears automatically
- Enable the platform safe zone overlay
- Check: is the subject in the safe area? Does text clear the UI zone? Does the motion read at small size?
- If yes — import. If no — fix the prompt, source material, or framing and regenerate
This replaces the old workflow of: generate → export → AirDrop → open on phone → realize the subject is behind the like button → go back to Premiere → repeat.
Limitations
Section titled “Limitations”| Limitation | What it means |
|---|---|
| Latest generation only | Each new generation overwrites the previous |
| Media links expire | fal.ai media URLs expire in ~24-48h |
| No same-network requirement | Goes through Cloudflare — works on any network |
| Offline | App shell loads, but no new previews without internet |
| Multi-image cap | Maximum 4 images shown per generation |
| Requires active license | Mobile preview silently skips without active license |
In real projects
Section titled “In real projects”Meta ad campaign: Generate a 9:16 video. Phone preview appears automatically. Enable TikTok safe zone — check that the product and headline clear the bottom UI strip. Looks good — import. Next variation.
Instagram Reels, multiple options: Use Dual Mode to generate two model variations simultaneously. Both appear on mobile as labeled slides — swipe to compare on the actual screen. Pick the stronger one, import.
Client review on the spot: You’re in a meeting. Generate a new variation. Hand the client your phone — they see it fullscreen, autoplaying, on the screen format it’s designed for. No projector, no screen share, no file transfer.
Agency handoff: Share the Copy link with a colleague — they see your latest generation on their phone in real time as you generate.
Common failure modes — if generation fails or preview doesn’t appear on mobile.
