Maintaining 4K Resolution in NowSignage

Maintaining 4K Resolution in NowSignage

When uploading videos to NowSignage, the selected codec determines how the file is processed. By default, projects are set to the VP9 codec. However, it’s important to note that all standard codecs (H264, H265, VP8, and VP9) support a maximum resolution of 1080p. This means that if you upload a 4K video while using one of these codecs, it will automatically be downscaled to 1080p by our AWS video conversion service.

How to Enable 4K Video Playback

If you need to display videos in 4K resolution, you must switch the project’s codec to either VP9 (4K), VP8 (4K) or H265 (4K). These codecs support rendering files at a maximum resolution of 4K. However, there are a few key considerations before making this change:

1. Project-Wide Change—Switching to any of the three 4K codecs applies to the entire project, any existing videos you wish to be 4K will need to be deleted and re uploaded into your content dashboard. If this is not done, the existing videos are not automatically converted to 4K.

2. Hardware Compatibility—Ensure that all hardware in your project supports the 4K codec you wish to use before making the switch. We recommend testing it on a single device before applying it across the project.
