SeedVR2 Video Upscaler: restore 480p and 720p clips to crisp 1080p or 4K online
Setting up the local seedvr2_videoupscaler node inside ComfyUI requires multi-gigabyte FP16 or INT8 checkpoints, compatible CUDA drivers, and 12 GB to 24 GB of VRAM before your first five-second test even renders. This page embeds the hosted SeedVR2 video upscaler directly in your browser so you can upload an MP4, MOV, WebM, MKV, or AVI up to 500 MB, inspect the exact credit quote before anything runs, and evaluate temporal stability on real motion without managing Python environments.
Launch the hosted SeedVR2 video upscaler
Trim a representative five-to-fifteen-second excerpt containing faces, camera motion, or fine texture before uploading a full timeline. Drop a video file up to 500 MB or paste a public HTTPS URL, choose SeedVR2 1080p or 4K Pro, read the preflight credit quote, and confirm only when the numbers fit your project.
Browser upload limit: 500 MB. For larger files, paste a publicly accessible HTTPS URL. Each job supports videos up to 10 minutes.
Quick scene presets
Presets pick a model for a common scenario. You can still switch models manually below.
Upscaled preview
Compare the enhanced output before exporting the final file.
Upload a clip, paste a direct video URL, or load the sample. No example video is downloaded until you ask for it.
Tip: keep your original FPS and avoid pre-scaling. The upscaler handles cadence better than most NLE plugins.
Test before processing the full video
Upscaling cannot recreate detail removed by heavy messaging compression. Test the hardest 5–10-second segment first; a higher-priced model is not automatically a better fit.

How SeedVR2 video upscaling differs from traditional resamplers and local nodes
Conventional NLE export scalers and older single-frame sharpening filters evaluate each video frame in isolation, averaging neighboring pixels without understanding how edges move across time. On compressed 480p archive transfers, screen recordings, or 720p AI-generated clips from Sora, Kling, Wan, and Seedance, single-frame filters amplify mosquito noise and create distracting frame-to-frame boiling across hair, foliage, and fabric.
The SeedVR2 architecture uses a shifted-window diffusion transformer paired with causal video VAE encoding so spatial detail recovery stays anchored across consecutive frames. People searching for seedvr2 video upscaler or the ComfyUI seedvr2_videoupscaler node are usually chasing that exact balance: cleaner eyelash, skin, and architectural micro-contrast without the waxy plastic sheen common in older GAN enhancers.
Running those 3B or 7B weights locally still demands steep hardware headroom—one long 1080p clip can exhaust an 8 GB or 12 GB laptop GPU unless tile sizes and color correction flags are tuned by hand. Our hosted browser lane handles checkpoint loading, tiled inference, and MP4 delivery in the cloud while letting local power users compare against our step-by-step ComfyUI documentation whenever they want.
- Temporal windowing keeps reconstructed texture stable across panning shots and talking heads.
- No Python, PyTorch, CUDA, or multi-gigabyte safetensors downloads required to test a clip.
- Upload once from any modern browser and inspect the returned MP4 at 1:1 pixel zoom.
Preparing your source clip for the cleanest SeedVR2 pass
Always hand the SeedVR2 video upscaler your earliest, least-compressed export rather than a file downloaded back from messaging apps or social feeds. Every extra H.264 re-encode carves fresh 8x8 macroblock boundaries into dark gradients, forcing the diffusion pass to spend capacity cleaning encoder damage instead of restoring real scene detail.
Export your selected range without burned-in captions, lower-third banners, channel watermarks, or artificial sharpening filters. Typography and vector logos rendered natively at 1080p or 4K inside Premiere Pro, DaVinci Resolve, Final Cut Pro, or CapCut stay razor-sharp without risking neural letter distortion.
If your footage comes from interlaced analog tape or includes dramatic speed ramps, deinterlace to progressive frames first and apply optical-flow retiming after upscaling. Clean progressive frames give temporal attention layers reliable motion vectors from start to finish.
- Trim directly from the camera or generator master with sharpening turned off.
- Keep subtitles, UI callouts, and brand watermarks on separate NLE tracks above the video.
- Deinterlace legacy tape before upload; apply slow-motion retiming and film grain afterward.
Selecting between SeedVR2 diffusion, Standard 1080p, and 4K Pro
Inside the embedded workspace above, you can switch between model lanes and target resolutions depending on source condition and delivery screen. SeedVR2 at 1080p is ideal when upgrading soft AI-generated video, webinar footage, or vintage clips where generative detail recovery matters more than raw pixel count.
Standard 1080p offers fast, economical daily cleanup at 540 credits per billed minute when your source already has decent structure and simply needs crisp HD delivery. When preparing hero B-roll, documentary archive masters, or clean 720p/1080p plates for UHD monitors and living-room televisions, stepping up to 4K Pro delivers full 3840x2160 resolution.
Rather than guessing across a ten-minute edit, cut the single toughest five-second shot—fast hand movement, fine text in the background, or dim indoor lighting—and test that slice first. Watch the output at normal 1x playback speed before deciding whether the entire sequence warrants 1080p or 4K.
- Choose SeedVR2 1080p for soft AI generations, compression haze, and organic textures.
- Choose Standard 1080p (540 credits/min) for fast, budget-predictable HD cleanup.
- Validate a five-second high-motion slice at 1x speed before batching longer timelines.
Audio preservation and non-destructive editing round-trip
Cloud video super-resolution dedicates GPU memory exclusively to visual frame reconstruction, leaving your original dialogue, music stems, and loudness mix untouched in your timeline. Once your upscaled MP4 finishes, drop it onto a track directly above the source clip in your editor and keep your original audio locked underneath.
For standalone single-clip deliveries where you are not using a non-linear editor, you can remux the original audio stream losslessly in under two seconds with FFmpeg (`ffmpeg -i upscaled.mp4 -i source.mp4 -c copy -map 0:v:0 -map 1:a:0 final.mp4`) without re-encoding either stream.
Check shot-to-shot consistency across cuts at 100% viewer zoom. Blending a touch of fine timeline grain or matching contrast curves ensures restored archival or AI inserts sit naturally beside native 4K camera footage.
- Stack the enhanced visual MP4 above your original edit track to keep master audio untouched.
- Use lossless stream copy when remuxing standalone clips outside an editing timeline.
- Match subtle grain and black levels across adjacent cuts for seamless master delivery.
Clear per-second credit math before you spend anything
Every video job on SeedVR2.net displays its exact credit requirement after reading your file duration, chosen model, and output resolution. On the Standard 1080p reference tier, processing costs 540 credits per minute (32,400 credits per hour), rounded up from a 5-second minimum with a 10-minute limit per file.
One-time public credit packs start at $19 for 800 credits when you just need to finish a single project without a recurring bill. Weekly creators and post-production teams can lower per-credit cost with Starter ($39/mo for 3,100 credits), Creator ($99/mo for 8,900 credits), or Studio ($149/mo for 14,400 credits), with annual Creator bringing effective cost down to $0.0093 per credit (~$5.01/min at Standard 1080p).
Because billing tracks verified clip duration rather than timeline length, trimming away head slates, black leader, static title cards, and unused B-roll handles before upload is the fastest way to cut project spend in half.
- Standard 1080p reference rate: 540 credits/min (~$5.01/min on Creator annual).
- One-time packs start at $19 (800 credits) with no subscription lock-in.
- Trim unused handles before uploading so every credit goes toward final screen time.
What the SeedVR2 video upscaler will and will not fix
Diffusion video restoration tightens recoverable structure and suppresses compression noise, but clear expectations save both time and credits.
- Severe camera shake, rolling-shutter wobble, and broken frame cadences should be stabilized or repaired before running super-resolution.
- Illegible license plates, tiny distant signage, and heavily smeared faces lack ground-truth detail and must never be used for forensic identification.
- Hosted jobs output the enhanced video stream; preserve multi-track audio inside your editor or remux losslessly after download.
- Browser uploads cap at 500 MB and 10 minutes per clip; split long recordings by scene or pass a direct HTTPS URL.
- Upload only footage you own or hold permission to process on cloud GPUs, and keep untouched archive masters backed up locally.
SeedVR2 Video Upscaler FAQ
Is there a free trial for the SeedVR2 video upscaler?
Eligible signed-in accounts receive one free 2K image upscale to verify visual quality and account delivery end to end. Because multi-frame video diffusion consumes dedicated cloud GPU time from the first second, video jobs require credits from a $19 pack (800 credits) or a subscription, and the exact cost prints before you confirm.
How is this different from the ComfyUI seedvr2_videoupscaler node?
The ComfyUI seedvr2_videoupscaler node runs open-weight 3B or 7B checkpoints on your own NVIDIA GPU after you install Python dependencies and download several gigabytes of safetensors files. Our hosted web tool runs in any browser with zero local VRAM or setup, making it fast for Mac users, laptops, and editors on deadline.
What video formats and maximum file sizes can I upload?
You can upload MP4, MOV, WebM, MKV, or AVI files up to 500 MB and up to 10 minutes per clip directly in the browser, or paste a directly reachable HTTPS video URL. Trimming to the exact shots used in your edit keeps uploads fast and credit usage lean.
How many credits does a 1-minute video upscale require?
Exact credit cost depends on duration, model lane, and target resolution (720p, 1080p, or 4K). As a benchmark, Standard 1080p bills 540 credits per minute (about $5.01 at the Creator annual rate of $0.0093/credit) with a 5-second minimum per job.
