What is Video Bitrate

Part 1. What is Bitrate in Video

This section will present necessary information regarding video bitrate. You will gain background about its function or role in the video. So, what is bitrate in the video?

Bitrate is the number of video data transferred at a specific time. It primarily affects the quality and size of the video. So, the higher the bitrate, the better quality, and the larger it will be. For streaming videos, bitrate is commonly described in megabits per second and audio in kilobits per second. Bitrate deals with the speed at which your file is being processed.

Part 2. Video Bitrate for 1080p and 4K

This part will provide the video bitrate of 1080p and 4K video resolution. The 1080p resolution is a high-definition video with 1,920 pixels horizontally and 1,080 pixels vertically. In contrast, 4K resolution is an ultra-high definition video with 3,840 horizontal pixels and 2,160 vertical pixels. How about their corresponding video bitrates?

1. SDR Uploads

Type Video Bitrate: Standard Frame Rate Video Bitrate: High Frame Rate
1080p 8 Mbps 12 Mbps
2160p (4K) 35-45 Mbps 53-68 Mbps

2. HDR Uploads

Type Video Bitrate: Standard Frame Rate Video Bitrate: High Frame Rate
1080p 10 Mbps 15 Mbps
2160p (4K) 44-56 Mbps 66-85 Mbps

The corresponding video bitrate for 1080p and 4K relies on whether it is a standard or high frame rate. In addition, you have learned that there are two sets of standards: SDR uploads and HDR uploads.

Part 3. How Does Bitrate Affect Video Quality

Video bitrate affects video quality in numerous ways. It is the key measurement of any video file size. Second, low bitrates result in poor video quality.

To further explain, an unreasonably high bitrate can strain your desktop hardware and data bandwidth, which may lead to glitching. In particular, the maximum bitrate for 1080p for high-definition bitrate is 10,000 - 15,000 kbps.

Part 4. What is a Good Video Bitrate

This section will present the considered good bitrate for videos, depending if it is a full or regular high-definition video. So, what is a good video bitrate? Please, check out the following information.

  1. For full high-definition videos with a standard resolution, input bitrate between 3,500 to 5,000 kbps.
  2. For regular high-definition videos with a standard resolution, input bitrate between 2,500 to 4,000 kbps.
  3. The input bitrate is between 4,500 to 6,000 kbps for high-resolution high-definition videos.
  4. For regular high-definition videos with high resolution, input bitrate between 3,500 to 5,000 kbps.
