2026 migration guide — updated for the new free tier

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: 200 signup credits plus 100 daily (capped at 300), 1080p video with synchronized audio in about 30 seconds, no watermark on video 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 no watermark on video. Written as a step-by-step, not a pitch.

Why migrate in 2026

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.

Step-by-step migration (about 7 minutes)

  1. 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.

  2. Open ZSky AI (signup optional)

    Visit zsky.ai/create. You can generate without creating an account. A free account unlocks 200 signup credits plus 100 daily, capped at 300. No credit card required.

    Sign in with Google, Apple, Microsoft, Discord, GitHub, or email — pick whichever is fastest.

  3. 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.

  4. Generate and compare

    Click Generate. A 1080p clip with synchronized audio renders in about 30 seconds (45 credits). Compare directly to your Runway archive.

    Two immediate differences: (1) ZSky output has no watermark on video, 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.

  5. Optional: Pro, Ultra, Max — or keep Runway too

    For ongoing speed, Pro at $19/month adds 3,000 monthly credits and instant generation (skip the queue). Ultra at $49/month unlocks 4K and 16-second clips. Max at $99/month adds 30-second clips and API access.

    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 you gain by switching

🎶

Audio on every clip

Synchronized audio is included on every tier including free. No extra credits. No second pass.

🌷

No watermark on video

ZSky never watermarks video output. Runway’s free tier stamps your output; ZSky never does.

📅

Renewable credits

100 free credits every day you log in, on top of 200 at signup. Runway’s 125 is one-time.

Dedicated GPU speed

7 NVIDIA RTX 5090 GPUs, self-owned, physically in the US. Consistent ~30s generation.

💰

Commercial use free

Commercial license on every tier including free. Runway restricts commercial use to paid tiers.

📝

Image generation too

1080p images in about 2 seconds at 1 credit each. 50+ styles. Runway charges image generation separately.

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:

No motion brush. Runway’s motion brush — painting directional motion on a still image — is a distinctive feature. ZSky approximates the same result via detailed text motion descriptions plus first-frame and last-frame anchors, but it’s a different workflow.
Cinema-grade polish. Runway’s top tiers are still widely used for professional film and commercial work. ZSky is competitive at social and marketing scale but does not currently aim at cinema-grade fidelity. If your work is destined for a 40-foot screen, Runway remains the serious option.
No dedicated video editor. Runway has a full NLE-style editor inside the product. ZSky is generation-first — you export the MP4 and assemble in your own editor (DaVinci, Final Cut, Premiere, CapCut).
Max clip length is 30s. ZSky tops out at 30-second clips on Max. Most Runway content is already in the 4–10s range, so this rarely matters, but chain clips if you need longer.

Frequently asked questions

Why migrate from Runway ML to ZSky AI?
Runway restructured its free tier in late 2025 to 125 one-time credits with a watermark. ZSky AI offers 200 signup credits plus 100 daily credits (capped at 300), 1080p video with synchronized audio, no watermark on video output, and commercial use on every tier including free.
Will my Runway prompts work on ZSky AI?
Yes. Text-to-video prompts transfer directly. Strip Runway-specific flags. You may want to add a short audio cue because ZSky video has synchronized audio whereas Runway’s free tier does not include audio.
Does ZSky AI support image-to-video like Runway?
Yes. Upload a reference image and animate it with a text prompt, equivalent to Runway’s image-to-video mode. ZSky supports first-frame and last-frame control to anchor your shot.
How do I cancel my Runway subscription?
Log in at runwayml.com, open Account Settings, go to Subscription, and click Cancel Plan. Your existing credits usually remain valid until the billing period ends. See our dedicated cancellation walkthrough for step-by-step screenshots.
What do I lose by leaving Runway?
Runway’s specific features like motion brush, camera control presets, video-to-video editing, and the cinema-grade polish of Runway’s top tiers. You gain renewable free credits, audio on every clip, no watermark on video, and dedicated RTX 5090 GPUs.
Is ZSky AI’s video quality comparable to Runway Gen-3?
For most social, marketing, and creative use cases, ZSky’s 1080p output is competitive. Runway still holds an edge for professional cinema-grade polish. ZSky’s Ultra and Max tiers narrow this gap with 4K output and longer clip lengths.
Does ZSky AI watermark video like Runway’s free tier?
No. ZSky AI never watermarks video output — on any tier, including free. A small image watermark applies only to images on the free tier.
Can I use ZSky AI videos commercially?
Yes. Commercial use is allowed on every ZSky AI plan including the free tier. There is no additional licensing fee and no watermark to strip.
How fast is ZSky AI compared to Runway?
ZSky AI renders a 1080p clip in about 30 seconds on dedicated RTX 5090 hardware. Runway times vary with cloud load. Pro ($19/month) and above get instant generation with no queue.
Is there an API?
Yes. The Max plan ($99/month) includes API access. Runway also offers an API. If API is central to your workflow, ZSky’s Max tier is the direct comparison.

Renewable credits. Audio on every clip. No watermark.

Start for free. 200 credits on signup, 100 every day you log in. No card, no Discord, no setup.
