Best AI video upscaler models, compared

A generative video enhancer built on LTX 2.5. Rather than only sharpening what is already in the frame, it redraws fine texture such as skin, hair, foliage and fabric while keeping the shot's layout and motion. It is made for soft, low-detail and AI-generated footage that needs more than a cleanup. Because it invents detail, it can change small faces, logos and text, so for footage that must stay exactly as filmed, SeedVR2 or FlashVSR is the safer choice.

A fast, self-hosted video upscaler for footage that already looks decent and just needs more resolution. It adds sharpness and detail at a low cost per second, and its temporal model keeps motion stable across frames. Best when the source is reasonably clean to begin with. For very low-resolution or heavily degraded video, SeedVR2 is the stronger, pricier choice.

ByteDance's SeedVR2 in video mode, the highest-quality and most expensive video upscaler we offer. It shines on very low-resolution or degraded footage, reconstructing a clean, usable base resolution where lighter upscalers fall short, with factor or fixed target resolution up to 4K. The cost per second is high, so reach for it when the source genuinely needs heavy restoration. For video that already looks decent, FlashVSR or GAN reach a higher resolution for far less.

The most affordable video upscaler, a per-frame GAN that adds resolution and crispness to footage that already looks decent. It has no temporal model, so it has less temporal consistency than FlashVSR, with minor flickering between frames that becomes more noticeable on low-quality input. But it is fast and the lowest cost per second. Good for quick, budget upscales of clean sources. For very low-resolution or degraded video, SeedVR2 is the better choice.

The fastest video upscaler we offer, powered by NVIDIA's video super resolution technology. It is a deterministic restorer: it sharpens edges and removes compression artifacts while upscaling, and stays temporally stable — no flicker between frames. It does not invent new detail, so for rescuing very low-resolution or heavily degraded footage SeedVR2 remains the stronger, pricier choice. It shares our lowest per-second rate with GAN, and differs in character: GAN adds bite on fine texture and can shimmer, this stays clean and steady. The right default for clean-ish footage that needs a fast resolution lift.
