Impress 8.5.0 released

06 March 2024

We are very happy to announce a New Release of Impress!

What’s new in

  • File Conversion:
    • Video files can be converted to an uncompressed AVI file via the media bin item's context menu.  
    • A video file can now also be partially converted to uncompressed AVI via the media bin item's context menu using the in- and outpoint as range for the partial conversion. 
  • FFMS: Update of library from to version
  • Added 'Auto recovery' setting (Settings\Filtering) for acceleration regarding CUDA errors. When these CUDA errors occur a restart of Impress is required (for now) so that CUDA will become responsive again. This new feature automatically switches the filtering to the CPU to at least continue filtering. The accelerator GPU will be restored after the next restart of Impress. (Report CUDA errors/crashes experiences here.)
  • The Super Resolution filter has been extended with a registration plot showing the sub-pixel displacements of the registered frames used for the super resolution fusion stage. If multiple frames result in a Registration Plot with distributed points (on both axis) than the one may expect a better interpolation result than a condensed Plot. This indicator will aid users in determining if it is likely that information can be won from interpolating the frames. (Simplified speech: a little bit of movement: more information can be won; no movement: no extra information to be won.)

    Screenshot of the Sub-pixel Plot (right-bottom) in Super Resolution detail window.
    (FYI: The right image is showing interpolated result based on video source file.)

What is improved 

  • System General Feature Expansion
    • Hybrid deblock: 
      • The Block Offset calculation has been improved. This automatic calculation will now display the certainty value (percentage) indicating how good the location of the Grid Offset of the compression blocks could be determined. 
      • In the newly added manual mode (Automatic = Off) the offsets can be set by the operator to further tweak the filter result. 
  • User Performance Facilitation 
    • Extra guidance information is added to the Track tab page of the stabilization and Super Resolution filters, which shows the correlation landscape. 
    • Extra guidance information is added to the Power Spectrum tab page of the deblur filters, which can be used for optimization of noise reduction. 
    • Timeline Scaling: 
      • The Time(line) Scale and Offset of the Timeline Control are restored when reloading a video file, so the user can quickly continue where they left off. 
      • A zone option button (three dots) is added to the time scaling area with the options: 
        • Reset time scaling.
        • Scroll to the thumb (available if scaling is active).
        • Set the scale to focus on the in- and outpoint range.

  • Visual updates
    • New layout of application popups 

What’s fixed 

  • Fixing the (single precision) float implementation of the Hybrid deblock filter.
  • Fixing missing index in converted media files in the media bin.

Previous: What’s new since

  • CUDA accelerated version of the Hybrid deblock filter. (Also speed and implementation improvements have been made to the CPU variant of the filter.)
    • Version 12.3 of the CUDA Toolkit is now used. (Download and install it from our User Portal or Nvidia if you want to us it.)
  • New basic instructions and tips in bottom right section of filter detail windows. 
  • New buttons to the status bar to inform and easily control through popup windows:
    • Internal pixel format.
    • Render engine.
    • Accelerator used.

Screenshot: 3 Status Bar controls opened.

What is improved

  • System Feedback
    • When removing key frames, one has to confirm to protect the work of setting the key frame positions.
    • Warning added, if certain hotkeys are selected for keyboard settings that cause focus problems.
    • Error messages are added if wrong or double hotkey settings are selected.
  • System Performance
    • Speed and implementation improvements of CPU Hybrid deblock filter.
  • System General Feature Expansion
    • Adding statistics to pipet tools Squash, and Equal Luminance and colour.
    • In Spline mode the shape stays stationary before the first and after the last key frame position.
  • Visual updates
    • Adding icons to all main menu items and detail window for better recognizability.
  • User Performance Facilitation
    • The ‘Open Case’ menu option now opens the case selection window versus the standard windows open dialog.
    • Deselection of annotation shapes can now be accomplished by clicking on the image canvas (the area surrounding the image).

What’s fixed

  • Fixing the hotkeys for move next and move previous. These were by default Left Arrow and Right Arrow. These default values caused focus problems when used. Now the ALT + Left Arrow and ALT + Right Arrow are the default values if not changed by user. 
  • When reloading a pipeline that contains one of the filters: Super Resolution, Stabilization, Frame Averaging or Temporal Smoothing, the video is automatically jumped back to the reference frame of the filter to avoid loading errors. To reach the final result of the previous session one has to play back to the previous location of the video file.
  • After reconnection to the current media file, needed for some settings no longer launches a blocking dialog, but an automatically closing popup window.
  • Fixing high CPU usage during idle time.
  • Fixing initialization errors of the Super Resolution filter.
  • Saving the main display subtitle settings has been fixed.
  • Recent cases menu items are available again.
  • Removing unnecessary network timeouts at application startup.
