With the Video Playback Source and Image Resolution feature in Studio, it’s easy to switch between showing smaller, optimized video or image files or the larger, original uploaded video or image files - so you can select what the best playback option is for your specific screen.
For example, using the Video Playback Source feature’s default Optimized option will play optimized video files that have been compressed to a maximum of 1080p resolution, but selecting to use the Original option will play the original video files, which could be a higher resolution than 1080p, for example, 4K or even higher.
It’s similar to the Image Resolution feature, using the default Optimized option will play optimized image files that have been compressed to a maximum of 1080p resolution, but by selecting to use the High option will play the highest resolution version of an image possible, up to 4K resolution.
An important thing to note though is that when you choose for a screen’s Video Playback option to be Original, you’ll want to be sure that the screen’s display or device powering the display can play that originally uploaded video file.
For example, if you upload a 4K H.264 MP4 file and then select a screen’s Video Playback Source option to be Original instead of the default Optimized, but that screen’s display is being powered by a device that does not support 4K video playback, you might have issues. As such, it’s important to ensure that the video files you upload to your media library are compatible with and can be played by your screen’s display or device powering the display. For more information on this, please see the “Supported video formats, operating systems and platforms” section below.
With images, it’s more simple, as most devices should be able to display every image format, but do note that selecting a screen’s Image Resolution option to be High, may affect the performance of your device.
To understand these features better, let’s take a look at both in more detail.
How to use the Video Playback Source feature
To set the video playback source for a screen, go to the "Screens" section in Studio and select a screen.
Next, on the right-hand sidebar, select the Settings tab.
Then, scroll down until you see the Video Playback Source option.
Next, select which video playback source you would like to use. If you want your screen to play the original video files that were uploaded to your media library, select the Original option.
Supported video formats, operating systems, and platforms
Supported operating systems and platforms
Currently, the Video Playback Source feature is supported by devices running the following operating systems and platforms:
ScreenCloud OS
Android
Fire OS
ChromeOS
Windows
macOS
Tizen (SSSP)

Supported video formats and guidelines
ScreenCloud supports video playback across multiple devices and operating systems. While compatibility may vary per device, the following formats have been tested and are recommended for reliable use:
MP4 (H.264) up to 4K at 30/60fps
WebM up to 4K at 30/60fps
MOV up to 4K at 30/60fps
To ensure smooth video playback, follow these bitrate guidelines:
1080p videos: Keep bitrate between 5–10 Mbps for reliable local playback. Bitrates above 15–20 Mbps may cause buffering or switch playback to streaming.
4K videos: Bitrates between 15–50 Mbps are typical, but anything above 20 Mbps should be compressed or optimized to prevent playback issues.
By following these guidelines and optimizing file format and bitrate, you’ll ensure your videos play smoothly and reliably across all ScreenCloud-supported devices.
