The name, the model, the paths
Seedrv2 is SeedVR2, spelled with capitals
People search for Seedrv2, seedrv2, or Seed VR2 and mean the same thing: SeedVR2, ByteDance's open-source model that restores and upscales low-resolution, compressed, or damaged video and images. The correct spelling is one word, capital S, capital V, capital R, then the numeral 2. There is no separate product called Seedrv2, and the hosted upscaler, the ComfyUI template, and the research repo all refer to the same SeedVR2 model family.
This is a SeedVR2.net explainer for the name, the model, and the ways to run it. SeedVR2 is ByteDance's Apache-2.0 video and image restoration model. Naming, checkpoints, and hosted limits are as published at review time; confirm against the live tool and the official repository before a paid job.
Try SeedVR2 without a spelling lesson or a GPU
The hosted upscaler runs the same SeedVR2 model family in the browser. Upload a short lawful source or paste a public HTTPS video URL, pick 1080p, read the credit preflight, and download the finished file. No local weights, no ComfyUI graph, no graphics card.
First eligible 5-second 720p Standard run: free
Verify your email to use your first video run without credits or a card. A failed run does not use the trial; longer clips and other settings show their exact credit cost before submission.
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.

One word, capital S, V, and R, then 2. Seedrv2 and Seed VR2 are search variants.
Published by the ByteDance Seed research group as an open-source release.
Permissive open-source license covering the published research code and checkpoints.
Restoration and upscaling for both video frames and still images.
ByteDance publishes 3B and 7B variants; quantized versions are community builds.
Seedrv2 or SeedVR2: one product, one spelling
SeedVR2 is a single proper noun. The lowercase seedrv2 and the spaced Seed VR2 are search spellings, not separate releases. If a download, a node, or a checkout page says Seedrv2, it almost certainly refers to the same SeedVR2 model. The capitalization matters mainly for finding the right repository and the right template, not for running the model.
The confusion is common enough that search engines return the hosted tool for any of these spellings. Use the canonical SeedVR2 when you cite the paper or the repository, and do not waste a download on something named Seedrv2 that promises a different model, because no such separate model is published by ByteDance.
What SeedVR2 actually is
SeedVR2 is a diffusion-based restoration model for video and images. It takes a low-resolution, compressed, noisy, or damaged source and reconstructs a cleaner, higher-resolution result. It is not a simple resize: a plain upscale stretches pixels, while SeedVR2 rebuilds plausible detail from the signal that survives in the source.
ByteDance publishes the official 3B and 7B checkpoints under Apache-2.0. The 3B variant is the lighter entry point, and the 7B variant is the heavier alternative. Quantized or FP8 versions are community or integration builds, not upstream releases, so do not attribute their behavior or memory claims to ByteDance.
- Diffusion-based restoration for video frames and still images.
- Apache-2.0, with official 3B and 7B checkpoints.
- Quantized variants are community builds, not upstream releases.
Three ways to run SeedVR2
The lowest-friction path is the hosted SeedVR2.net upscaler: no GPU, no model files, and a credit preflight before submission. It fits occasional jobs and machines without a workstation graphics card. The tradeoff is that the source leaves the local machine for hosted processing.
The second path is local ComfyUI, which runs the official weights on your GPU. It is free if the install works, but the first finished file only appears after models, nodes, and VRAM are sorted out. The third path is an API such as fal or WaveSpeed, which exposes the same model family for about $0.01 per image when the catalog holds and you already have keys.
- Hosted browser: fastest start, credits per job.
- Local ComfyUI: free if it boots, but models and VRAM are your problem.
- API: about $0.01 per image if you already have keys.
There is no separate product called Seedrv2
ByteDance does not publish a distinct Seedrv2 model. Any site that sells Seedrv2 as a different or newer product than SeedVR2 is describing the same model family with a typo. Treat the names as interchangeable for discovery, but check the actual repository, license, and checkpoints before you install or pay anything.
The practical takeaway is simple: search Seedrv2, land on SeedVR2, and run the same hosted tool or the same ComfyUI template. Do not install a second, mystery-named package on the assumption that it is more capable, because the name difference carries no model difference.
Upscale your first clip under the right name
Open the hosted upscaler and add a source: a browser file up to 500 MB or a public HTTPS video URL, up to ten minutes. Pick 1080p as a safe first target, read the credit preflight, and submit. The first signed-in 2K can finish on trial, which is the cheapest way to confirm the model works on your footage before you commit more.
Review the result at delivery size and normal speed, then scrub frame by frame for faces, text, and motion. If a section fails, change one variable and re-run only that section. The spelling of the name will not change the output, but the resolution, source trim, and review will.
Naming and model limits
This page is a name and model explainer, not a controlled benchmark. Checkpoints, hosted limits, and credit amounts change; confirm against the live tool and the official repository before a paid or local install.
- Seedrv2 and Seed VR2 are search variants, not separate ByteDance releases.
- Restoration cannot recover detail the source never captured.
- Quantized or repacked variants are community builds with their own behavior.
- Hosted inference depends on network access and provider availability.
Seedrv2 and SeedVR2 questions
Is Seedrv2 a different model from SeedVR2?
No. Seedrv2 is a lowercase misspelling of SeedVR2, ByteDance's open-source video and image restoration model. There is no separate Seedrv2 release; the hosted tool, ComfyUI template, and research repo all refer to the same model family.
What is the correct spelling?
SeedVR2, one word with a capital S, V, and R, then the numeral 2. Seedrv2 and Seed VR2 are common search spellings that refer to the same product, so they are safe to search but not the canonical name.
What license is SeedVR2 under?
ByteDance publishes SeedVR2 under Apache-2.0, a permissive open-source license. Quantized or FP8 repacks are community builds, so check their own licenses and do not assume ByteDance publishes them.
How do I actually run SeedVR2?
Three ways: the hosted SeedVR2.net upscaler with no GPU, a local ComfyUI install with the official weights, or an API such as fal or WaveSpeed. The hosted path is the fastest for a first clip; the local path is for a repeatable offline graph.
