SeedVR2 vs FlashVSR
SeedVR2 vs FlashVSR.
Pick by Source:
Stills to 8K, Clips to 4K.
Short answer: SeedVR2 is our detail-recovery engine for images and single frames, up to 8K; FlashVSR is built to upscale whole video clips to 4K. We host both, so here is an honest guide to picking one — and you can try either free with signup credits.
Model Options
Choose the workflow that fits your scene
Start with a prompt, add references when needed, and pick the generation path that matches the output.
FlashVSR (upscale video)
Pick FlashVSR when your source is a moving clip. It upscales footage up to 4K while preserving motion and temporal detail, billed per second from a 5-second minimum for clips up to 10 minutes.
SeedVR2 (upscale images)
Pick SeedVR2 when your source is a still — a photo, a render, or one extracted frame. It is a detail-recovery model, so it reconstructs textures and faces rather than just smoothing them, up to 8K.
Why use it on Moosky AI
Powerful tools. Seamless experience.
FlashVSR: video-first
Purpose-built for clips. Upscales up to 4K and keeps motion coherent frame to frame instead of flickering.
SeedVR2: detail recovery

We host both
Most tools push you to one engine. Because Moosky runs both, this is an honest pick-the-right-one guide, not a sales pitch.

Both use Moosky credits — 100 credits per $1 — with the cost shown before you run. No subscription for either.

Frequently Asked Questions
SeedVR2 vs FlashVSR — what is the real difference?
They solve different jobs. SeedVR2 is a generative detail-recovery model for images and single frames — it rebuilds lost texture and facial detail, up to 8K. FlashVSR is a video upscaler that takes a whole moving clip and raises its resolution up to 4K while keeping motion and temporal detail consistent. If your source is a still, use SeedVR2; if it is footage, use FlashVSR.
Which is better for video, SeedVR2 or FlashVSR?
FlashVSR, because it is the video engine. It upscales clips to 720p, 1080p, 2K, or 4K targets with per-second billing (a 5-second minimum charge, clips up to 10 minutes). SeedVR2 is designed for images, so for actual clips FlashVSR is the right tool.
Is SeedVR2 free?
SeedVR2 generations are not free — they are billed in Moosky credits at about two cents per image by default, with the exact cost shown before you run. New accounts can use signup credits to try it, and there is no subscription. That is usually what people mean by 'free': you can start without a recurring bill.
Can I use both in one project?
Yes, and often you should. A common workflow is to restore or clean a key frame with SeedVR2's detail recovery, then run the full clip through FlashVSR for the video upscale. Both draw from the same credit balance, so there is no separate plan or export step.
Which one should I choose if I only upscale occasionally?
Whichever matches your source. Choose FlashVSR for video clips and SeedVR2 for photos or frames. Since Moosky charges per generation rather than monthly, you are not locked into either — buy credits, use the engine your file needs, and stop when you are done.
