This video upscaler runs on SeedVSR, a diffusion transformer that collapses multi-step inference into a single forward pass. The result is a video upscaler that processes files 10× faster than traditional diffusion models while producing comparable or better quality — one inference step to 4K, no iterating or waiting.

Unlike most video upscalers that only handle one media type, this tool accepts MP4, MOV, PNG, JPG, and WebP in a single interface. The same SeedVSR model powers the video upscaler for both videos and images, so you can upscale a clip and its thumbnail without switching tools.
Old home footage, classic anime at DVD resolution, blurry screenshots, AI-generated images — this video upscaler was trained on exactly this kind of degraded material. It predicts what the missing detail should look like based on learned patterns, producing sharp, natural output instead of the mushy results you get from basic resize.
The video upscaler runs on SeedVSR, a diffusion transformer that collapses multi-step inference into a single forward pass using adversarial post-training. In practice, this means it’s about 10× faster than traditional diffusion upscalers while producing comparable or better quality. The model was developed by ByteDance Seed and trained on millions of high-resolution frames.
SeedVSR processes clips up to 25 seconds long in a single pass. That covers most short-form content — TikToks, Instagram Reels, intro sequences, and individual scenes. For longer videos, check out our Video Enhancer tool, which splits and processes videos up to 10 minutes.
This is where the video upscaler shines. Grainy VHS transfers, early phone recordings, blurry security footage — SeedVSR was trained on exactly this kind of degraded material. It can also partially interpolate missing frames in choppy video. It won’t colorize black-and-white footage, fix faded colors, or repair damaged faces though.
Anime and cartoons are a sweet spot for SeedVSR. The model handles flat color regions and sharp line art beautifully, so your classic DVDs or 480p downloads come out looking like they were drawn at 4K. No mushy edges, no artifacts — just clean upscaling that respects the original style.
Unlike most video upscalers that only handle video files, this tool accepts both video (MP4, MOV) and images (PNG, JPG, WebP). The same SeedVSR model handles both media types, which is handy if you’re working with mixed content — upscale a thumbnail and its source clip in the same tool.
Every upload goes through automated content moderation. The video upscaler doesn’t process pornographic or illegal material. This keeps the platform safe and ensures GPU resources go to legitimate upscaling work.
Drop a video (MP4, MOV) or image (PNG, JPG, WebP) into the video upscaler — up to 50 MB. Videos can be up to 25 seconds long.
The AI analyzes your file and generates upscaled detail in a single inference step. No settings to configure. A short clip takes 2–5 minutes; images are usually done in under a minute.
Toggle between the original and upscaled version to see the difference. Then download — no watermark added. Files stay available for 14 days.
That camcorder footage from 2005 or the VHS tape of your parents’ wedding — these are exactly the kinds of files the video upscaler was built for. SeedVSR recovers detail that basic upscaling can’t, turning grainy memories into watchable HD.
Got a classic anime at DVD resolution? This video upscaler can take it to 4K without making the lines blurry or the colors muddy. SeedVSR understands the difference between illustrated and live-action content and adapts accordingly.
TikToks, Reels, YouTube Shorts — if you shot something on an older phone or downloaded a low-res clip you want to repost, the video upscaler can bring it up to HD or 4K quality. Better resolution means better engagement on every platform.
Not just video — you can upscale images too. Drop in a PNG, JPG, or WebP and SeedVSR will enhance it to 4K resolution. Great for product photos, thumbnails, or any image where you need more detail than the original provides.
Enhance videos, clean audio, compress files, and more.
