over 5 years ago by Encoding.com Product Team
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
