test.full.band - open source video testing/calibration patterns
This is a thread for community discussion of open source pattern set from the test.full.band project (look also for the sources on test-full-band/tfb-video project at GitHub).
This is a young project and doesn't yet contain all the common useful patterns, and initially was focused on providing something unique, not yet existing elsewhere. But this is changing with time and transforms into complete set of video patterns for the purposes of testing video reproduction equipment such as TVs and media players and for calibrating them.
The latest released version of the patterns can be always found at:
Releases · test-full-band/tfb-video
Features
Modern picture formats
Setup & Tests
Calibration patterns
Special for LG OLED
We are welcoming contributions. If you can do something to the project - please join. We need help with documentation, contributions of code for new patterns (it is mostly Java), feedback about features and bugs, and of course discussions.
Currently 'We' consists of only me, but I hope it is not for long and together we can do something big. May the force be with us!

Calibration patterns
- Full screen fills and 5%, 10%, 20%, 50% window calibration patches
- Grayscale patterns in 5% steps
- additional 'Whiter than White' patterns
- additional precision near-black patters (1% steps)
