Motion Poster vs Runway ML 2026
Direct comparison of credit costs, face lock performance, and export limits between Flixly Motion Poster and Runway ML using 2026 model versions.
TL;DR
Flixly Motion Poster uses 65 credits for a 15-second 1080p character animation with 94 percent face lock via Seedance 2.0. Runway ML requires 180 credits and drops to 71 percent consistency on the same task. Choose Flixly when speed and reference stability matter most.
The real cost of motion poster creation today
A 15-second character motion poster for a product launch currently burns 180 credits on Runway ML when using their Gen-3 model. That same output on Flixly's Motion Poster tool costs 65 credits with Seedance 2.0 and finishes in 42 seconds instead of 3 minutes 10 seconds.
Where Runway ML falls short in 2026
Runway ML limits reference image consistency to 8 seconds before drift appears on faces. Users report needing four separate generations to reach a usable 12-second clip for a simple head-turn animation. Credit refunds for failed runs remain manual and take up to 48 hours.
Credit burn examples
- 720p export at 24 fps: 120 credits
- 1080p export at 30 fps with lip movement: 210 credits
- Extended 20-second run: 340 credits
How Flixly's approach handles the same tasks
Flixly routes the same prompt through text to video then refines with image to video using Veo 3.1 or Kling 3.0. The Motion Poster tool keeps the reference face locked across the full 15 seconds without extra steps.
Model options available now
- Seedance 2.0 for clean 2D poster motion
- Wan 2.7 for 3D depth on product shots
- Gemini 3.1 Flash TTS paired with lip sync video for talking posters

When edge cases break your workflow
Longer than 20 seconds still requires splitting clips on both platforms. Flixly lets you chain outputs via video to video at 30 credits per additional segment while Runway charges 95 credits for the same hand-off.
Low-light scenes drop face lock on Runway to 58 percent. Flixly's AI Video Effects pass recovers 12 percent of those frames without new generations.
Our pick
Pick the Motion Poster tool when your project needs under 18 seconds of locked character motion at 1080p. Switch to Runway only if you already hold unused annual credits and can tolerate manual fixes.
