Part 2. 8K Video File Size - How Big Is an 8K Movie File

What are the factors affecting 8K UHD video size?

Bitrate: The higher the bitrate, the more fluent the video and the larger the file size (video size = bitrate x time). First, Bitrate should neither be too high or too low. The former only leads to staggering big file size, while the latter one will be against your will of compressing 8K video without quality loss. Besides, some UHD video compressor enables you to choose between CBR (constant bit rate) and VBR (variable bit rate). Simply, to compress a 8K action movie video, use VBR; drama movies, CBR.

Resolution: Changing video resolution also helps compress and reduce 8K video slightly. Considering your display resolution, you can change from 7680 x 4320 to 3840 x 2160 for playback 8K video on 4K TV, compress 8K video to 1920 x 1080 for playback on FHDTV/iPhone, etc.

Frame rate: 8K requires up to 120 fps. Relatively, frame rate is of little use in 8K video compression, which always varies from 23.97 to 30 and has to be in line with YouTube/Vimeo uploading requirements.

Now, you can reduce 8K video file size while maintaining Ultra HD quality --> better for saving local space, bandwidth, etc --> uploading faster on YouTube --> easier for loading online with no stuttering --> more compatible with portable devices when playback. The output video won't look blocky and blurry and the video detail keeps reserved.

How many GB is an 1 hour 8K video?

According to Signiant, one hour of 8K RedCode Raw 75 amounts to 7.29 TB. That's 121.5 GB per minute for a raw 8K footage. 2-minute 8K video of 40 GB needs 349525 Kbps (341Mbps). None-compressed 8K video could turn out to be a still image in 4320p resolution. 8K resolution is 4 times the total pixels of 4K UHD and 16 times 1080p HD (8K vs 4K | 4K vs 1080p). And you may need not only a 8K video compressor, but also 8K video decoder/editor.
