Social media content demands volume, speed, and platform-correct sizing. GESTEL’s Fast engine and batch generation let you produce multiple variations quickly, while Relight and Animate add variety without reshooting.
Generate at the right ratio from the start — composition is framed correctly without post-crop.
| Platform | Format | Ratio |
|---|
| Instagram feed | Square or portrait | 1:1 or 4:3 |
| Instagram Stories | Full-screen vertical | 9:16 |
| Instagram Reels | Full-screen vertical | 9:16 |
| TikTok | Full-screen vertical | 9:16 |
| YouTube thumbnail | Wide landscape | 16:9 |
| Pinterest | Tall portrait | 3:4 |
| X / Twitter | Landscape | 16:9 |
- 3-second loops work well for Stories and Reels — they load quickly and the loop is seamless
- 5–8 second clips suit YouTube thumbnails animated as channel trailers or product previews
- Motion on fabric, hair, or background elements tends to look most natural
Start from your strongest, highest-contrast still image. Animate reads the scene depth and adds motion — results are better when the subject and background are clearly distinct.
Batch variations for A/B testing
Run multiple Fast generations (3 credits, 4 images each) with different background or style references to build a pool of variations for testing.
Example: a skincare product
- Run #1 — clean white studio background
- Run #2 — marble surface, natural light
- Run #3 — outdoor botanical setting
- Run #4 — urban street scene
You now have 16 images across 4 aesthetics for under 15 credits. Post variations across different time slots and track engagement to find what resonates with your audience.
Relight for mood variations
Edit → Relight (4 credits) lets you change the lighting on an existing image without regenerating from scratch. Use it to create mood variations from a single base image:
- Warm / golden — morning posts, lifestyle, seasonal warmth
- Cool / blue — evening, premium, minimal
- Rim + Warm — luxury, editorial
- Neon / gel — night, event, campaign
This gives you multiple posting options from one generation run, which is cost-effective for high-cadence posting schedules.
Fast engine for rapid iteration
Use the Fast engine (3 credits, 4 images) for social content exploration. Fast is suited for:
- Testing background variations before committing to Pro
- Generating content for Stories where image quality expectations are lower
- High-volume posting schedules that need consistent throughput
Switch to Pro (10 credits, 8 images) when the image is going to be pinned, featured, or used as a long-lived campaign asset.
Generate your content at 9:16 for Stories and Reels, then recompose a separate 1:1 run for feed posts. The composition changes meaningfully at different ratios — don’t just crop a vertical into a square.
