You’ve likely heard professionals discuss downsampling 8K videos to obtain better quality 4K footage. You might ask yourself: “What is downsampling and why would i reduce the quality my footage?” It’s a reasonable question! Let’s get to know the concept first before we talk about the why.
What is downsampling?
In video, downsampling is the process by which a video file’s size can be reduced by reducing its resolution and frame count. It is common to use downsampling to reduce the file size and make it easier for users to manage. As an example, a person might shoot a video at 8K, then downsample it to 4K to make the file easier to manage, store, and stream.
A person might also downsample video from 8K to 4K because it has a better image quality. 8K video is higher resolution than the 4K version. 8K video resolution is 7680×4320 while 4K resolution is 3840×2160. This means 8K video has four times as many pixels as 4K video.
When someone downsamples an 8K video into a 4K format, they can create a video with a better image quality than the 4K original. The video will look better even though it has a lower resolution because the finer details will be present.
What are the benefits of downsampling videos?
- Reduce the size of video files to make it easier to stream, store and share.
- The viewing experience can be improved by increasing the playback speed of the video.
- Reduce the file size to improve compatibility across different platforms and devices.
What are the disadvantages of downsampling videos?
- The video is less detailed due to the removal redundant data.
- The removal of redundant data can cause a loss of color and contrast.
- Loss of resolution can lead to a loss in quality.
How to downsample a video
It is easy to downsample video.
- Open the video in an editing program.
- Select the video clip you wish to downsample from the timeline.
- You can then select a lower quality in the settings of the clip.
- Export the video at the new resolution.
Remember that downsampling can lead to a loss in quality as the resolution will be reduced. It is therefore important to select the correct resolution for your video. The resolution you choose depends on many factors such as your viewing platform. TV, computer screen, etc.) The desired level of detail.
