What's new in VQ Probe v3.3

TS support for AVS3

We've added support for AVS3 streams packaged in TS containers.

New options to add RD curves automatically

We've introduced the feature to automatically add streams to RD curves. To set the RD Curves Auto Mode, go to Tools > Options > General > RD Curves.

Ability to drag streams between RD curves

You can now drag streams between RD curves. The streams will be removed from the original curve and added to the new one.

ROI Constructor

We've also introduced the feature to manually draw regions of interest (ROI) using the ROI Constructor dialog. Click and hold the left mouse button, then drag to outline the desired ROI.

New options for metrics calculation

We have added several new options for metrics calculation:

  • Scaling Mode for Convex Hull: sets the scaling mode for Convex Hull
  • GUI:
    • Show Cumulative Average Curves: enables/disables Cumulative Average curves
    • Show Dots on Curves: shows/hides dots on curves

Added the ability to display stream stats in Metrics Log

You can now inspect multiple statistics for every stream. Click the Stream Stats button in the Metrics Log to open the Stream Stats Log.
