## What it is
YUView is a Qt-based, cross-platform YUV video player with an advanced analytics toolset for inspecting raw video sequences. It supports many YUV/RGB formats, HEVC bitstream decoding with internal visualizations, FFmpeg-based file opening, side-by-side comparison, difference calculation, and statistics overlays.

## Use cases
- play and inspect raw YUV video sequences
- compare two video sequences side by side and view differences
- visualize HEVC internals like prediction modes and motion vectors
- overlay statistics data on top of video frames
- open almost any video file via FFmpeg
- analyze video codec output quality frame by frame
- zoom into video frames to inspect pixel-level details

## When to choose
- you need to view or debug raw YUV or RGB video data
- you are developing or researching video codecs like HEVC/H.265
- you need frame-accurate comparison and difference analysis of video sequences
- you want to visualize codec statistics such as motion vectors or prediction modes

## When to avoid
- you just need a general-purpose media player for watching videos
- you need automated batch video processing or transcoding pipelines
- you require a headless or command-line-only video analysis tool
