FlashVSR
Our dedicated video upscaler: take a whole clip up to 4K while keeping motion, faces, and temporal detail intact — not just a sharpened single frame. Billed per second for clips from 5 seconds to 10 minutes, so a short post costs cents.
SeedVR2 image upscaler
If your source is a single frame or photo rather than a moving clip, SeedVR2 is our detail-recovery engine for stills, up to 8K — on the same credit balance.
Why use it on Moosky AI
Powerful tools. Seamless experience.
Up to 4K restoration
Enlarge and clean up footage — old home videos, low-res downloads, AI renders — up to 4K while faces, text, and edges hold together.
Motion-safe upscaling
Unlike frame-by-frame sharpening, FlashVSR keeps temporal detail consistent so the upscaled clip does not flicker between frames.
Pay per second
Credits are billed by the second of output, so a 10-second clip and a 3-minute clip cost what you'd expect. No $10-$30 monthly upscaler subscription.
Free to start
New accounts get free signup credits to test your first clip before you pay anything.

Upscaled clips ship clean and ready to publish, hand to a client, or reuse commercially.

Frequently Asked Questions
What is the best AI video upscaler?
For whole clips, a purpose-built video upscaler beats image upscalers: it keeps motion and temporal detail consistent instead of sharpening each frame separately. Moosky runs FlashVSR for exactly this, up to 4K, with per-second pricing and no software to install.
Can I upscale a video from 720p to 4K for free?
You can start free: sign up and receive signup credits, then run your first clip. After that you pay per second of output on a prepaid credit balance (100 credits per $1) — there is no quality-crippled free tier, every run gets the full model.
How does video upscaling differ from image upscaling?
Image upscalers like SeedVR2 enhance a single still, up to 8K. Video upscalers must also preserve motion across frames so the result does not shimmer. FlashVSR is the video engine; use it when your source is a moving clip.
How long of a clip can I upscale?
FlashVSR on Moosky handles clips from 5 seconds up to 10 minutes, with target resolutions of 720p, 1080p, 2K, or 4K. The cost scales with the seconds and target you pick, shown before you run.
Which should I use, FlashVSR or SeedVR2?
Source is a moving clip → FlashVSR. Source is a single frame or photo → SeedVR2 image upscaling. Both live on the same credit balance, and there is a full side-by-side guide if you want the longer comparison.
