Video Resolutions: HD, 4K, 6K, and Beyond

Video resolution refers to the number of pixels in each frame of video. Full HD is 1920 by 1080 pixels, often called 1080p. 4K is 3840 by 2160 pixels, which is exactly four times the pixel count of 1080p. 6K is roughly 6144 by 3456 pixels, and 8K is 7680 by 4320 pixels. Higher resolution means more detail and more flexibility in editing, but also much larger files and more demanding hardware requirements.

1080p is still the most widely used resolution for delivery. Most online platforms, television broadcasts, and even cinema screens can display 1080p content perfectly. For content that will primarily be viewed on phones, tablets, and computers, 1080p is often sufficient. It is easy to edit, fast to render, and produces manageable file sizes. Shooting in 1080p is a practical choice for many projects.

4K is the current standard for professional video production. Even if your final delivery is 1080p, shooting in 4K gives you flexibility. You can crop the frame, reframe shots, and apply stabilization without losing quality. Downsampling 4K to 1080p produces a sharper, cleaner image than shooting natively in 1080p. 4K also future-proofs your content as more displays become 4K capable. Most modern cameras shoot excellent 4K video.

6K and 8K are used for high-end production and specific workflows. Shooting in 6K gives you even more cropping room and produces stunning 4K downsampled results. Some cameras record 6K or 8K to oversample for 4K output, meaning the camera captures more pixels than needed and combines them for a cleaner 4K image. 8K is still niche due to massive file sizes and limited distribution options, but it is used for archival and large-screen productions.

Higher resolutions require faster memory cards, more powerful computers, and more storage space. A minute of 4K video at a moderate bitrate might be 400 megabytes. At 8K, it could be several gigabytes. Before committing to a high resolution, make sure your computer can edit that footage smoothly. Proxy editing, where you edit with smaller files and then render from the originals, is a common workflow for high resolution video.
