06 February 2019 - QC Updates

Deprecated qc_check_only

❗️
Note
qc_check_only output format was temporary deprecated due to unstable working.

QC Auto/All

We can run automatically generated QC test on your media based on API request parameters and source media properties.

There are 2 types of automatic test sets:

Auto - most common tests to quickly check media quality
All - almost all tests that we can apply to your media
