AI Video Upscaler
This ai video upscaler runs SeedVR2 through fal on your own silent MP4 or WebM, up to 60 seconds and 80 MB. Output doubles your source's width and height and aligns both edges to a multiple of 16 pixels — an 854×480 source returns 1712×960 — capped at a 3,840px longest edge and 8.29 megapixels per frame. Pricing is 0.25 credits per output megapixel across every frame; 3 seconds of 854×480 runs about 30 credits. Sign in and upload your clip; the server measures it and shows that exact quote, valid for 5 minutes, and only charges once you confirm. Results are private, silent MP4s listed under Recent jobs (latest 20); a provider or output-validation failure refunds automatically, and you can leave and recover the job after signing in again. 4× scaling and audio-bearing input aren't offered yet. You must have the rights to any video you upload.

SeedVR2 · September 21, 2026 · 2× · 2 seconds · 24 frames · silent. Both videos are displayed at the same size.
Full decoding and dimensions verified. Pastry and cloth textures look sharper in inspected frames; this is a selected AI-generated scene, not proof of recovered real-world detail. 4×, audio, faces, fine text and fast motion are not validated by this sample.
