What exactly is 8K resolution?

8K UHD (Ultra High Definition 2) refers to a display or video frame that is 7680 pixels wide and 4320 pixels tall (7,680 x 4,320 = 33,177,600 total pixels), progressive scan, at a 16:9 widescreen aspect ratio. The term "8K" approximates the ~8000-pixel horizontal count. It delivers four times the pixel count of 4K UHD and sixteen times the pixel count of 1080p Full HD.

What bitrate should I use for 8K video?

For 8K streaming at 30 fps with H.265/HEVC, 100–200 Mbps is a typical target. YouTube recommends 80–160 Mbps for 8K30 and around 240 Mbps for 8K60 (H.264). With AV1 or H.266/VVC, similar quality can be achieved at roughly half the H.264 bitrate. Camera raw 8K (e.g. RED MONSTRO, Sony Venice 2) can easily exceed 3–6 Gbps depending on the codec.

How much storage does one hour of 8K video take?

At 100 Mbps (H.265, 8K30): 100 Mbps x 3600 s / 8 = approximately 45 GB/hour. At 200 Mbps it is roughly 90 GB/hour. Camera raw 8K (12-bit RAW or BRAW at high frame rates) can exceed 1–2 TB/hour depending on the codec, bit depth, and frame rate.

Is 8K visible to the human eye at normal viewing distances?

The perceptual benefit of 8K requires a very large screen or close viewing distance. On an 85-inch TV viewed from 6 feet, 8K (104 PPI) is noticeably sharper than 4K (52 PPI). On a 32-inch monitor from 24 inches, 8K (276 PPI) surpasses the retina threshold for most adults. Use the PPI calculator on this page to evaluate your specific setup.

What HDR standards are used with 8K?

8K displays support the same HDR ecosystem as 4K: HDR10 (open standard, 10-bit, static metadata), HDR10+ (dynamic metadata), Dolby Vision (dynamic metadata, 12-bit capable), and HLG (broadcast-friendly). Most 8K TVs also support the HEVC Main 10 profile to decode 10-bit HDR content efficiently.

How does 8K compare to 4K in file size?

8K has exactly 4x more pixels than 4K UHD (33,177,600 vs 8,294,400). At the same codec and bitrate efficiency, 8K files are roughly 4x larger than 4K. Efficient codecs like H.265 or AV1 partially offset this, but 8K still demands substantially more storage and bandwidth than 4K.

What cameras shoot 8K natively?

As of 2025, consumer-accessible 8K cameras include the Samsung Galaxy S21 Ultra and later (photo mode), Sony A1, Canon EOS R5, Nikon Z9, and RED V-Raptor 8K. Professional cinema cameras like the Sony Venice 2, ARRI Alexa 35, and RED MONSTRO 8K VV also capture 8K or near-8K footage.
