YouTube HDR live streaming is now possible!



We are proud to officially announce that after 3 months of hard work with awesome people from YouTube Team we are ready with HLS HDR live streaming! YouTube is currently the only live streaming platform to support this feature.

Yesterday, YouTube has unblocked HLS HDR streaming support for everyone so you can try it right away! (Action v4.12.2 or newer is needed)

And with Action 5 Scene Maker you will be able to create complex live streams with top quality, performance and effects like in a real TV studio.

Action! 5 COMING SOON

Hi Everyone!

First of all we are sorry for not being active for the past few months as we have been busy improving Action 4 and preparing Action 5!
We are super excited with this new version as it will be our ultimate app dedicated even for the most demanding users!

A short intro:

Action 5 will be available in two trims:
- Action 5 Basic, which follows the line of Action 4 being a simple, yet powerful screen and game recording app (with basic streaming functionality)
- Action 5 Scene Maker a separate app with much more features for advanced streaming and recording.

We are going to release Action 5 in phases:
PHASE 1: Action 5 Basic will include a new AI powered (software and hardware accelerated) camera background removal algorithm (December 2020)
PHASE 2: Action 5 Scene Maker will be available for testing via Steam Playtest (Q1 2021)
PHASE 3: A streaming overlay themes pack will be added with many cool graphic compositions (Q2 2021)

Last but not least new screenshots from Action 5!

Action 4.10.0 with 8K HDR recording is ready!



Hi creators and gamers!

Today we have uploaded version 4.10.0 with 8K and 8K HDR video recording support! We are now ready for the future as we can squeeze up to 45fps of 8K video using RTX 2080 GPU. 8K also works for newest Intel GPUs. Of course GPUs are not capable of 8K gaming today but it is just a matter of time. We are eagerly waiting to get our hands on Nvidia RTX 3000 family of GPUs and hope to reach 60fps 8K HDR video capture soon.

Below a list of changes in this version:
  • NEW easy to use selected application window recording/streaming and recording/streaming of multiple desktops in a single video (link to video tutorial is available below)
  • Added support for 8K MP4 video capture for newest Intel and Nvidia GPUs
  • Fixed system/driver crash after hardware PlayReady 3.0 DRM is enabled with Action running
  • Fixed 240fps recording in HDR mode
  • Fixed Vulkan HDR capturing in active screen mode
  • Stability improvements


Presented feature requires Windows 10 version 1903 (or newer)
