Test video which exposes compression quality

[illus]

Is there an industry standard which is used for testing compression quality - something similar to what the tests bars are to analogue TVs?


I guess a video with features as described in https://forum.videohelp.com/threads/143560-Test-file-for-encoding-test-%28need-help%29?highlight=test

There isn't a common trustworthy measurement of quality, so an industry standard to test for something like visual quality is kind of problematic.
There are a bunch of short test sources people like to use for codec evaluations like: http://media.xiph.org/video/derf/

The "bird" sample from Planet Earth is often used as a such a stress test.

Anything with lots of film grain is also very difficult. Especially in dark areas.

Is the original available anywhere, maybe uncompressed video ?

Ask the BBC. The Blu-ray disc is probably the best you're going to find otherwise. The sample that post was probably re-encoded from the Blu-ray release.
