Runway to ZSky: 2026 Migration Guide
Runway ML tightened its free tier in late 2025 to 125 one-time credits at 720p with a watermark. ZSky AI is a renewable free destination: unlimited generation (ad-supported) (capped at 300), 1080p video with synchronized audio in about 30 seconds, HD video with synced audio on the free tier (1080p on Pro/Ultra, 4K on Max); free-tier output (videos AND images) carries a small 'MADE WITH / zsky.ai' wordmark plate output, and commercial use on every tier. This guide walks through the full workflow migration in 7 minutes.
For creators who liked Runway but want a renewable free tier, audio on every clip, and HD video with synced audio on the free tier (1080p on Pro/Ultra, 4K on Max); free-tier output (videos AND images) carries a small 'MADE WITH / zsky.ai' wordmark plate. Written as a step-by-step, not a pitch.
Why migrate in 2026
- Runway’s free tier shrank. 125 one-time credits with a 720p watermark is a trial, not a tool. ZSky’s unlimited free tier (ad-supported) is permanent.
- Audio is a workflow unlock. Runway free tier is silent. ZSky adds synchronized audio to every clip at no extra cost — no second pass in a video editor.
- HD video with synced audio on the free tier (1080p on Pro/Ultra, 4K on Max); free-tier output (videos AND images) carries a small 'MADE WITH / zsky.ai' wordmark plate, ever. ZSky never watermarks video — not on free, not on Pro, not on Max. Runway’s free output has a Runway mark.
The founder’s why
ZSky AI was built by an artist for artists. Founder Cemhan Biricik has aphantasia — he cannot picture images in his mind — and healed from a traumatic brain injury by learning photography. The camera was the first tool that let him see his ideas externally. AI generation is the next evolution of that same tool.
The pencil became the camera. The camera became AI. The tool changes, but the human impulse to create does not. Every pricing decision on ZSky is filtered through one question: does it expand access or restrict it? That’s why the free tier is permanent, why every paid tier has full commercial use, and why watermarks never touch video output.
Runway is a serious professional platform. If you’re making cinema at scale, keeping a Runway plan still makes sense. This guide is for everyone else — the freelancer, the marketer, the hobbyist — whose free tier got pulled out from under them.
Your Runway workflow → ZSky equivalent
| Runway feature | How it worked | ZSky equivalent |
|---|---|---|
| Text-to-video | Generate clip from prompt | Text-to-video at zsky.ai/create, 1080p + audio in ~30s |
| Image-to-video | Animate a still image | Upload image, prompt motion, 1080p animated output |
| Extend clip | Continue a generated clip | Chain clips via last-frame anchor — extract final frame, feed as first-frame anchor |
| Frame interpolation | Smooth motion between frames | Built-in smooth motion on 1080p output; manual frame interpolation not exposed |
| Camera control presets | Dolly, orbit, pan | Describe camera motion in the prompt: “slow dolly in”, “orbit right”, “crane up” |
| Motion brush | Paint on still image | No direct equivalent — approximate via first/last-frame anchors + text motion description |
| Green screen / remove background | Runway chroma key tool | Background removal in image editor (2 credits) |
| Text-to-image | Separate Runway generator | Same generator, 1 credit, ~2s at 1080p, 50+ styles |
| Watermark on free | Yes, Runway mark on free output | HD video with synced audio on the free tier (1080p on Pro/Ultra, 4K on Max); free-tier output (videos AND images) carries a small 'MADE WITH / zsky.ai' wordmark plate — any tier |
| Commercial use | Paid plans only | Allowed on every tier including free |
| API access | Available | Developer API on Max tier ($99/mo) — 300 vid + 1000 img/mo, resets monthly |

Step-by-step migration (about 7 minutes)
-
Export your Runway prompts and reference images
Open each Runway project and copy the text prompt into a notes document. Download any reference images or source frames you want to reuse. This gives you a clean starting library for ZSky.
If you’re planning to stop paying Runway, cancel auto-renew now so the decision doesn’t slide. Runway usually honors remaining credits until the period ends — verify this in your billing settings.
-
Open ZSky AI (signup optional)
Visit zsky.ai/create. You can generate with a free account. A free account unlocks unlimited generation (ad-supported), capped at 300. No credit card required.
Sign in with Google, Apple, Microsoft, Discord, GitHub, or email — pick whichever is fastest.
-
Paste your Runway prompt — adjust the knobs
Paste the prompt directly. Remove any Runway-specific parameters. The descriptive content transfers.
Add an audio cue. ZSky video has synchronized audio. A short direction like “cinematic score with soft wind” or “urban traffic ambience” shapes the audio layer. Skip it and ZSky picks scene-appropriate audio automatically.
Pick aspect ratio and length. Use the built-in selectors instead of Runway’s parameter flags.
-
Generate and compare
Click Generate. A 1080p clip with synchronized audio renders in about 30 seconds. Compare directly to your Runway archive.
Two immediate differences: (1) ZSky output has HD video with synced audio on the free tier (1080p on Pro/Ultra, 4K on Max); free-tier output (videos AND images) carries a small 'MADE WITH / zsky.ai' wordmark plate, and (2) ZSky clips have audio. For most content work, those two deltas alone cover the migration pain.
If a generation fails, credits are refunded automatically. Runway and most competitors charged on failure.

Optional: Pro, Ultra, Max — or keep Runway too
For ongoing speed, Pro at $19/month is ad-free with priority GPU on the dedicated RTX 5090 fleet. Ultra at $49/month unlocks 4K and 16-second clips and all features. Max at $99/month adds a dedicated GPU, 30-second clips, white-label, and Developer API access (300 vid + 1000 img/mo, resets monthly). Docs at zsky.ai/api-docs (Max subscribers only). Higher volume on request.
If Runway’s motion brush or cinema-grade polish is essential to a specific client, it’s fine to keep a light Runway plan and use ZSky for everything else. Tools aren’t monogamous.

What’s different (honest accounting)
A migration guide that only lists wins is a sales pitch. Here’s what you’ll notice is different when you move:
