Known Issues
- If matte is selected on the Mattes Tab and a save state is triggered, the matter looses its name and ends up removed.

Tape Measure Tool Improved – measurements are now shown as X/Y/Z measurements with reference to scene coordinates.
“edit_” in Collada scenes are now enabled.
“black frame” bug fix – fixed issue when changing frame rates, a 4k video that is paused would show a black frame. Now it shows the first frame of the video.
Updated Default Sensor Size List – added F5, F55, PMW350, C300, C500.
Removed redundant step in Lens Calibration cycle.
Survey Markers default to more elegant size (0.5 of previous markers for better viewing).
Added missing tooltips to “Horizon line” and “Wireframe”

Smoothing defaults to Airtrack 1.5 threshold values.
fixed bug when lens is set to min zoom and infinity focus.
720/50Hz Input Format. Format not fully implemented, but listed.
secondary “high speed” output disabled.
Updated Default Sensor Size List – updated Alexa Plus 4:3, Alexa Studio, Alexa (16:9 mode), Red Epic, Red Scarlet.

Airtrack 1.5 Compatibility
Select-able Save States Parameters. Completely new System States with the ability to selectively pick the parameter for which to load from a given System Save State.

System Save States formatted as xml files that can be exported/imported at any given time.
Select-able transmit parameters when controlling multiple Previzion systems.
Completely new Lens Calibration interface and procedure. Use of a “fixed position” lens calibration with various improvements which include but are not limited to:
- Click-able lens matrix to select which point to calibrate next
- Real-time 3D graph representing the various parameter of the lens
- Ability to edit specific points from within the Lens Calibration interface in Previzion
- Offline Lens Mapping of Lens Calibrations – Captured full resolution images that generates a lens calibration file that allows for archiving and potentially re-process a lens
- Little to no need for Lens Grapher editing
- Lens Calibration
- Import/Export Legacy Calibration Files
- ability to calibrate to “infinity” focus
Ability to make video depth (“subject depth”) lock to a specific surveyed coordinate, using markers.
Addition of “Enable Foreground” as scene effects to allow for “Background” only rendering when using CPU intensive scenes.
