When we talk about the video, there has been an increase in image quality over the years. We can now enjoy movies and record our videos in 4k high resolution. 4k has taken our watching experience to a completely different level. However, certain devices cannot play 4k video properly, and that is when we need to lower its resolution without losing the 4k quality. There are many 4k HDR video converters, which can perform the task, but there are only a few converters that can retain the 4k quality while converting between the formats. 

What is the need for converting 4k HDR to 1080p SDR?

The main difference between 4k HDR and 1080p SDR is the difference in picture quality.

The image quality of 4k is the next level when compared to 1080p. Its resolution is about four times as compared to 1080p.

HDR stands for High Dynamic Range. It supports files that are big and give more color information. For HDR you need to have big storage and a very fast internet connection. On the other hand, if we talk about SDR, its screen projection is slightly muted and it has a low brightness too.

A 4k HDR file is very huge. If you record a 4k HDR video with your iPhone, it becomes too large to be shared with anyone.  We generally lower down the resolution and tweak the settings so that the size of the file reduces and it becomes easy to share. Furthermore, for the people who have old computers, it is not possible to play 4k HDR videos as old devices do not support 4k HDR videos. In these situations, you can convert 4k HDR to 1080p SDR to retain the same experience.
