4K Video Compression: Optimize File Size for Smooth Playback

4k resolution has become the new standard for high-quality videos, with the preference for ultra-high-definition content. Although videos of this quality ensure an elite viewing experience, sharing them can be a challenge due to their large file size. While you compress the file size, it is inevitable to lose its video quality throughout the process. Therefore, this article highlights 4K video compression to reduce file size while preserving the original quality.

Part 1. Does 4K Video Compression Always Result in Quality Loss?

Although the compression of a 4K video always results in quality loss, the extent of loss may vary. Choosing lower bitrates while reducing the file size adds pixelation or artifacts to the video. The quality also depends on the codec, as the older options offer slow processing and quality loss. Lossy compression means that the process discards some data from your original file and deteriorates the quality.

Part 2. Tips to Consider When Compressing 4K Videos

Video quality plays an important role in making a good impression on your audience. Therefore, follow the tips below to make sure that your original quality is preserved throughout the compression 4K video to 1080p:

1. Choose an Efficient Codec: As mentioned above, picking a new codec helps you achieve efficient compression. Therefore, select modern options like H.265, AV1, or VP9 to get a better experience.

2. Select the Bitrate Smartly: To avoid quality loss during the compression, choose a variable bitrate instead of a constant bitrate. If you are compressing for streaming purposes, it is recommended to use a bit rate of 15-25 Mbps. In comparison, you can use higher values of bitrate to compress a video for archiving.

3. Rely on a Lossless Compression Tool: Instead of using bad-quality lossy compression tools, it is better to pick a lossless platform. Besides providing customizable compression settings, these tools compress 4K video without losing quality.

4. Optimize Video’s Resolution and Frame Rate: While processing a 4K video, it is important to set the frame rate at 30 or 60 FPS. As for the resolution, you can downscale to 1440p to save storage while retaining sharpness.

5. Fine-Tune Compression Settings: While compressing your video file, opt for a CRF of 18-23 to get high-quality 4K compression. It is important to note that faster presets result in larger files, while slower presets offer better compression.
