VQ Probe 2.0: Buffer view, Convex hull, Command Line Interface and more

Today we are pleased to announce the release of an update of VQ Probe 2.0: a video comparison & quality metrics analysis tool, which will be useful not just for professional video codec developers, but also for streaming integrators and regular users. The new version of VQ Probe is out with a bundle of new and exciting features.

VQ Probe 2.0

The following new main features have been added to VQ Probe 2.0:

  • Buffer View gives a snapshot of bits distribution of the left and the right compressed streams.
Buffer View
  • VQ Probe builds a convex hull for the given set of RD Curves.
Convex hull
  • Command Line Interface. In addition to the GUI version, VQ Probe provides Command Line Interface (CLI). It can be used in batch mode validation.
Command Line Interface
  • ROI (a region of interest). Metrics can be calculated in a part of the picture - ROI. You can load rectangle coordinates from the file or detect objects with the integrated ML object detection model.
