AmritaVE
A free program that cleans compression artifacts out of video and pictures and upscales them with neural networks.
For anime, 3D/CGI, live footage and pictures. It also shrinks 4K video to 2K.

What it does
Removes artifacts
The DPIR network clears the blocks and mosquito noise left by YouTube and social media compression.
The right model for the picture
Anime goes through Real-ESRGAN, or Adore for good sources from 540p; 3D and live video through waifu2x Swin-UNet, which keeps skin and fabric texture. The type is recognised by the CLIP neural network, even on old grainy rips.
Smallest file, no visible loss
Compression is tuned by the VMAF metric: the AV1 10-bit file is as small as it can be without visible loss. Every result is compared with the master frame by frame, and a piece the encoder spoiled is compressed again.
A copy for websites
Next to the archive you get an H.264 copy that plays in any browser and on any phone.
Pictures too
PNG, JPG, WebP, BMP, TIFF and AVIF up to 4K. Maximum uses heavy DAT2 networks with 8 passes, Fast takes seconds. Transparency is kept.
Smooth motion
Optional: the RIFE network draws in-between frames, twice as many or up to 60 fps. Anime drawn on twos becomes smooth too, and scene cuts never blend into each other.
Your own neural networks
Add any upscaling network as an .onnx file, for example from OpenModelDB, or download checked ones from amvfeed.com. New versions of the built-in networks arrive the same way, without reinstalling.
4K to 2K
4K from YouTube often holds little real detail above 2K. If the frame is larger than the chosen size, the program just scales it down without a neural network, and the copy aims for no more than 70% of the source.
Colors stay true
Some neural networks and HDR sources make the picture pale. AmritaVE converts HDR to the normal range, corrects the color shift of the networks, keeps color profiles and 16-bit depth.
Metadata under control
See what a file stores: camera, date, GPS. Keep it, remove it or replace it with your own title and author, with or without upscaling.
Preview in seconds
Before a long run, look at before/after: 6 frames of a clip or the key spots of a picture, plus a 3-second clip when Smooth motion is on.
A before/after video
Every clip comes with a 12-second before/after video from its most detailed part: the source and the result in one frame, with the border gliding across. Ready to post.
Whole batches, overnight
Several clips go through a pipeline: while the processor compresses one, the graphics card already upscales the next. Clips added during the work join the queue. The computer stays awake, then can sleep or shut down, and your Telegram bot can tell you it is done.
Smooth gradients
YouTube compression leaves steps and blotches in dark and soft gradients, and a neural network only makes them bigger. In anime they are smoothed out in the 10-bit master and stop flickering from frame to frame, while thin lines stay sharp.
Sound, subtitles and chapters
Sound stays as it is when browsers can play it, otherwise it becomes AAC. Subtitles with their fonts and chapters carry over. You can trim the start or the end of a clip.
Everything stays on your PC
Your files are not uploaded anywhere: they are processed on your graphics card.
How to use it
- Install the program and start AmritaVE from the Start menu.
- Drag clips, pictures or a folder into the window (video: MP4, MKV, WebM, MOV, AVI).
- Press Preview to judge the result, then Start. The window shows in advance how long it will take.
- When everything is ready, Windows shows a notification. Press Open result.
Requirements
| System | Windows 10 or 11, 64-bit |
|---|---|
| Best graphics card | NVIDIA GeForce RTX 20 series or newer, driver 580 or newer |
| Other graphics cards | AMD Radeon, Intel Arc/Iris and older NVIDIA with DirectX 12 work 2–5 times slower and use simpler models for 3D, live video and pictures |
| Disk space | 1.6 GB for the program plus about 5 GB per 10 minutes of video while it works |
| Time | It is not fast: 10 minutes of anime on a laptop RTX 5060 take about 1.5 hours at Best quality and about 45 minutes at Fast |
| Time for pictures | On a laptop RTX 5060 about 3 minutes per megapixel of the source at Maximum, seconds at Fast |
| First run | The program prepares each neural network for your graphics card once, which can take up to 10 minutes |
Questions
Windows says “Windows protected your PC”
The program isn’t signed with a paid certificate yet, so SmartScreen doesn’t know it. Click More info, then Run anyway.
Why does it take so long?
The neural network processes every frame, then the program test-compresses the video several times to find the smallest size without visible loss. Choose Faster or Fast to save time.
Can I stop and continue later?
Yes. Press Stop: the finished stages are kept, and even an unfinished upscale continues from where it stopped on the next Start.
The video type was detected wrong
Pick the type by hand (Anime · 2D, 3D · CGI or Live video) and look at the Preview again.
What happens to 4K video?
If the frame is larger than the chosen size (2K by default), the program only scales it down and tunes the compression. The size is set on the first settings tab.
How do I remove metadata?
Choose Remove or Replace under Metadata and press Metadata only: you get copies without upscaling or re-encoding. The originals do not change, and the color profile stays, otherwise the colors would shift.
Something went wrong
The clip card says what happened. The Log file button opens the details; attach it when you ask us.
Does the program send anything to the internet?
Only one small request to amvfeed.com at start-up to check for a new version, and a message to your own Telegram bot if you turn that on. Your files never leave your computer.
