Infuse adds auto frame rate, SDR/HDR switching support on Apple TV 4K

29 Nov 2017 | Rasmus Larsen |

The next major software release, tvOS 11.2, for Apple TV 4K adds automatic frame rate and dynamic range switching. Infuse has updated its tvOS app to take advantage of the new features in anticipation of the release.

Owners of Apple TV 4K will have to wait for tvOS 11.2 to be released – unless you are prepared to install the public beta. However, Firecore, the company behind Infuse, wants to be at the forefront.

What this specifically means is that Apple TV 4K, starting with tvOS 11.2, will gain the ability to “automatically switch video display modes to match the native frame rate and dynamic range of video content”, meaning between frame rates such as 24, 30 and 60Hz as well as dynamic range formats such as SDR, HDR10, and Dolby Vision. This is an optional feature that must be enabled manually in the menu since it involves a brief black screen, which is a limitation of the current HDMI / HDCP standard.

All apps that take advantage of Apple’s standard video player will work out of the box. However, apps that have custom video players will need to make changes. Infuse is one such app and the company has made those changes with the latest app update (version 5.6.2) for tvOS. It adds ”automatic frame rate and dynamic range switching (tvOS 11.2 and later)”.

The update for Infuse was actually released last week but we missed it. We have installed the update on our Apple TV 4K and can confirm that it works as intended.

UHD Blu-ray and HDR

Earlier in November, Infuse also added support for UHD Blu-ray (ISO/BDMV), besides the major update in early November that added support for HDR video and a new Metal-based video player.

Infuse is an alternative to Plex on Apple TV 4K. Unlike Plex, it does not require server software to be installed on the storing device. However, Plex offers other features such as Live TV and news.

Apple has not announced a release date for tvOS 11.2 but based on the beta releases it will likely be made available some time in December.
