Action! 5 status update:
To improve UI performance we have to rewrite Action 5 rendering engine to work entirely in 3D. This will allow us to support dynamic scaling to any DPI (100%, 125%, 150%... user interface size).

This will also allow us to visualize 3D transitions between scenes and add amazing video effects in real time (like advanced sharpening, color enhancement and many others).

We are also releasing a new free add-on product soon: "Mirillis AI virtual cam" that will allow to remove webcam background in amazing quality and replace it with images or videos! You will be able to use it in any application (including Action of course) and on any CPU/GPU.

Thank you!

• To allow easier use of OriSound function (recording original audio directly from games and applications) a new Auto mode has been added.
  In this mode (with Game Mode set and audio device set to Selected Application) Action! will automatically switch audio source to selected/active game.
  
  
  
  
• Fixed AVerMedia GC573 4K HDR capture card sound support

• NEW FEATURE: Kernel Streaming (KSProxy) audio recording needed for capturing sound from capture cards like Elgato 4K60 PRO HDR (with this hardware it is now possible to record and livestream 4K/HDR video from Playstation 5 and Xbox Series X consoles)
• Fixed 7.1 audio downmix to stereo
• Improved OriSound (original soundtrack extraction from games and applications) function compliance with several anti-cheat systems

• NEW FEATURE: OriSound - long-awaited feature that allows to record audio exclusively from selected game or application!
  Don't waste money on additional PC or specialized headphones!
  Now you can select your favorite voice chat application (like Discord) and record it into separate audio track that will not be mixed with main audio track!
  Additionally the sound you record will never be modified by sound card post-processing so you always get the original volume, pitch and tone.
  It will also not get disturbed by random system "blips" comming from popup windows etc.
  
  HOW TO USE ORISOUND:
  1. Use "Selected application" from audio device list (either primary, secondary or aux device).
  
  
  
  2. A window will appear showing currently detected sound sources in the system (from system audio mixer).
  
  
  
  3. If the application you want record sound from is not running or is not visible on the list you can use the '+' button to select its exe file (you need to manually find its location first).
  
  
  
  NOTES: This feature might not work for anti-cheat protected games and some games with spatial audio like Dolby Atmos. This will be added soon in version 4.18.0.

Please kindly send us these files if a crash occurs and we will investigate them and provide a solution in the shortest possible time.
