# Anime Video Upscaler > An anime video upscaler raises the resolution of animated clips while keeping line art clean and flat colours free of blocks. Kenerate's AI Video Upscaler rebuilds anime and AI animation at 1080p, 2K or 4K with frame-consistent detail, so outlines don't flicker, and it keeps the original frame rate — no added in-between frames.

Stills, stickers and thumbnails. - AI image upscaler (7 engines): Photo or AI image → Up to 8K or 128 MP. Any still image. ## Steps 1. Export the cleanest copy — Use your project export or the original file; avoid clips re-saved from social apps. 2. Upload to the AI Video Upscaler — MP4, MOV or WebM, up to 5 minutes and about 100 MB. Split longer edits into sections. 3. Choose 2K or 4K for line art — Thin outlines benefit from more pixels; 1080p is fine for phone viewing. 4. Check the lines and download — Zoom the before/after on outlines and flat areas, then download the MP4. ## In depth ### Hard lines, flat fills Anime is drawn with clean outlines and flat areas of colour. Ordinary resizing averages neighbouring pixels, so black lines turn into soft grey ramps, and low-bitrate compression shows up as blocks and banding in the flat fills [1]. ### Anime-specific models Open-source projects have worked on this for years. Real-ESRGAN publishes anime models, including AnimeVideo-v3 for video [2], and Anime4K offers real-time upscaling and denoising shaders for players such as mpv [3]. ### Timing is part of the art Anime often uses a lower drawing rate than live action, especially in older productions [4]. Interpolating new frames can smooth that timing away, which is why Kenerate's upscaler leaves the frame rate untouched and only works on resolution. ### Video vs stills A still upscaler treats every frame alone, so tiny differences make lines crawl when the frames play in sequence. Video upscaling works with frame-consistent detail, so outlines stay put from one frame to the next.

A: The best anime video upscaler keeps outlines sharp, flat colours clean and the result stable from frame to frame. Kenerate's AI Video Upscaler does that in the browser at 720p to 4K for clips up to 5 minutes. For real-time upscaling during playback, open-source shaders such as Anime4K are another option. Q: How do I upscale anime to 4K? A: Upload the anime clip to Kenerate's AI Video Upscaler, choose 4K and start. It rebuilds each frame at the pixel count of 3840 × 2160 while keeping your aspect ratio and frame rate, and you download an MP4 without a watermark. 4K and longer clips take longer to process. Q: Is an anime upscaler different from a normal upscaler? A: Anime has hard ink edges and large flat areas, so a blurry resize turns lines grey and compression makes fills blotchy. Anime-tuned models exist — Real-ESRGAN publishes an AnimeVideo-v3 model — but any good video upscaler must also keep lines stable across frames so they don't shimmer. Q: Will upscaling change the frame rate of my anime? A: No. Kenerate keeps the frame rate and length you upload and does not add interpolated frames. That matters for animation, where held drawings and timing are deliberate choices that interpolation can smooth away. If you want smoother motion, add it in your editor as a separate, deliberate step. Q: Can I upscale anime images too? A: Yes, with a different tool. Kenerate's anime image upscaler handles fan art, stickers and manga pages at up to 4K or 8K, using Real-ESRGAN for clean line art. The video upscaler on this page is for moving clips, where frame-to-frame consistency matters. Q: Can I upscale AI-generated anime videos? A: Yes. AI video models often output 480p or 720p, so upscaling to 1080p, 2K or 4K is a common last step before posting. Upload the clip as an MP4, MOV or WebM of up to 5 minutes and about 100 MB. Q: Can I upscale episodes of anime series? A: Only upload animation you made, commissioned or otherwise have the right to use. Upscaling a copy of a commercial series doesn't change who owns it, and sharing upscaled episodes can infringe the rights holder's copyright. Your own shorts, commissioned work and AI-generated anime are the right fit for this tool. ## Related pages - AI video upscaler: https://kenerateai.com/ai-video-upscaler - Upscale video to 4K: https://kenerateai.com/upscale-video-to-4k - Topaz Video AI alternative: https://kenerateai.com/topaz-video-ai-alternative - Improve video quality: https://kenerateai.com/improve-video-quality - Anime image upscaler: https://kenerateai.com/anime-upscaler ## Sources - Kenerate AI Video Upscaler (tool): https://kenerateai.com/app/tool/video-upscale - Real-ESRGAN — GitHub (anime image and AnimeVideo-v3 models): https://github.com/xinntao/Real-ESRGAN - Anime4K — GitHub (MIT): https://github.com/bloc97/Anime4K - Limited animation — Wikipedia: https://en.wikipedia.org/wiki/Limited_animation
