File-Based 8K Master Finish Considerations
Similarities/Differences With 4K
When considering what resolution camera to use for the production, the first consideration should be the display solutions the content will be viewed on. That means doing comparison tests with your candidate cameras on the display device (theatrical / home / mobile) that will be most important in your decision making process.
It is well known, for example, that capturing at a resolution higher than the deliverable format provides higher image quality. That difference may or maynot be readily visible depending upon the display size and many other delivery factors. Besides better picture quality, capturing in 8K and having the ability to master (or re-master) in 8K or higher resolution later can afford you with additional longevity and financial benefits for long-term use.
Editing in 8K is not required. This can be done using lower resolution proxies for editorial. However, it is advisable to always view the 8K rendered content on the largest, highest quality consumer OLED or LED displays to see details and fine focus.
Grading can be done in 4K using proxies from the 8K masters. Then a conform and playback for final considerations should be done in 8K to ensure that fine D.I. manipulation work is holding up without noticeable artifacts. Always play back on the largest highest quality display device available.
Consumer 8K sets should be utilized with direct 8K connection to the grading system to ensure that they are NOT upscaling content. You always want to view natively for your final work adjustments.
Always view your 8K native master directly on an 8K display and ensure that no up-conversion is taking place on the display. In addition, encode the 8K content using various encoding parameters and codecs and view the content in on the 8K display to ensure the compression is proper and not introducing any noticeable artifacts.
Because several 8K codecs are available, it is wise to test them and compare encodes. Depending on the nature of the content, you may see a difference and can make the best decision on which to use. Delivery requirements from platforms may require usage of specific codecs, so ensure that you check.
