4K Limitations

Our software has the support for 4k, but your player device has to be capable as well. Our Windows/Linux/OSX devices treat 4K like any other format, however Android devices are using a workaround. Android devices (ARM processors) are quite weak compared to other hardware (x86), and the 4K playback on Android devices is optimized for certain codecs and applications only. For that reason, our app will launch the native player at the coordinates of the plugin and will play the video.

• 4K is played on top of all elements, including our app user interface elements, such as the download progress bar (in case you’re playing the video in full screen). This also means that slides with 4K can not use slide transition effects as the effects would occur behind the video element, thus not visible.
• If you request a screenshot from the web portal, the video will not be shown on the screenshot as it’s running outside of our app context.
• If you are using our software for portrait rotation (as opposed to operating system settings), the video will not be rotated. The portrait is still possible if the display can be rotated from Android operating system settings (Amazon devices lack this option). We’ve also discovered that Amazon’s 4K stick is incapable of playing a 4K portrait (2160 x 3840). You can work around this issue by rendering in 3840 x 2160 resolution instead, but the content in the video is rotated 90 degrees.
• Since the video starts up in an external program, there may be a slight delay (especially on the first load), therefore we recommend setting the slide background to black to avoid a white flash when starting up.
• Despite some manufacturers claiming that their device runs 4K, we’ve witnessed the 4K support to be rather limited or lacking (this is most often true for the cheapest Android devices claiming 4K capability).
