## What it is
Dandere2x is a tool that speeds up waifu2x video upscaling by exploiting temporal redundancy in anime footage, using P-frame compression so only unique frames need GPU processing. It is written in C++ and available as a desktop application with a GUI as well as a Docker image.

## Use cases
- upscale anime videos to higher resolution with waifu2x
- speed up waifu2x video processing
- denoise and upscale low-resolution anime episodes
- batch upscale anime-styled video files
- upscale videos using a GPU without processing every frame

## When to choose
- you want to upscale anime-styled video much faster than frame-by-frame waifu2x
- your footage has lots of static scenes or temporal redundancy typical of anime
- you want a ready-made GUI or Docker workflow for waifu2x upscaling

## When to avoid
- you need to upscale live-action video where P-frame matching works poorly
- you need real-time upscaling
- you need actively maintained software with recent updates
- you want to upscale non-anime images rather than video
