The Best 4K Video Bitrate – How to Change It for A Video

4K resolution refers to a display resolution of approximately 4000 pixels horizontally. There are 2 main 4K resolutions: UHD 4K and DCI 4K. UHD 4K has a resolution of 3840 x 2160 and is commonly used in televisions, gaming PCs, and other screens. DCI 4K has a resolution of 4096 × 2160 and is primarily used for professional film production.

Bitrate refers to the amount of video data transmitted per second over a network, measured in Kbps (Kilobits per second) or Mbps (Megabits per second). It affects the detail and sharpness of the video image. Generally, the higher the bitrate, the richer the detail and color in the video.

Bitrate and resolution affect different aspects of video quality. Resolution determines the sharpness of the video. While bitrate reflects the detail in each frame. If a 4K video has a low bitrate, it may appear blurry due to insufficient detail. However, 4K video quality doesn’t necessarily improve with increasing bitrate. Instead, resolution determines the highest quality that can be displayed.

Best Bitrates for 4K Video at 30 FPS and 60 FPS

There is no fixed bitrate parameter for 4K video. When discussing the bitrate of 4K videos, they are generally divided into 2 main categories: 30 fps and 60 fps. The following sections introduce the optimal bitrates for 4K video at these 2 frame rates.

Optimal Bitrate for 4K 30 FPS Video

For 4K video at 30 fps, if using H.264 video encoding, the optimal bitrate is typically between 30 Mbps and 80 Mbps. Within this bitrate range, video quality, file size, and transmission performance achieve an ideal balance.

Optimal Bitrate for 4K 60 FPS Video

Higher frame rate of 4K videos is often paid for with a higher bitrate to best showcase the 4K video viewing experience. The optimal bitrate range for 60 fps 4K video encoded using H.264 is 100 Mbps to 200 Mbps. A suitable bitrate maintains high-quality video and effectively reduces motion blur.
