File-Based 8K Capture Considerations
Capturing content in 8K or higher resolution affords the content owner a way to ensure the highest quality images for both current display devices and future display devices for both theatrical and in the home/portable market.
8K (and higher) Digital Cinema Grade cameras made by RED, Black Magic Design, Panavision, ZCam and Achtel can provide the highest quality images for theatrical and large format/screen use. Other new cinema grade cameras entering the market that are also 8K or higher are coming soon.
ProSumer 8K digital video cameras that can typically capture at up to 30 frames per second, are also now available. Even high-end smartphones can capture 8K videos meaning 8K capture is possible at any budget level. Based on end use needs, these cameras can provide the benefits to capturing in higher resolution.
The key to lens considerations is to “test” and “review” in the final delivery format you are shooting for. Lenses are a creative choice and thus the highest resolution lens may not always provide the desired look.
However, if the goal is to shoot and preserve the highest resolution, the best sharpest lenses would be the proper choice.
Final creative “look” can be achieved in the D.I./color timing process. It is always easier to “soften” and create a unique final look for your project than to lose perfect detail and resolution of 8K or higher cameras by not using the sharpest lenses.
Always record and store content shot with the highest quality camera settings and least amount of compression available. There is no reason to shoot in 8K or higher if you don’t preserve the best image the camera is capable of producing, so don’t try and save money on storage.
Back-up & Dailies Considerations
There are now many workflows for back up and dailies. Companies such as FrameIO and Pix provide professional applications for dailies review with the ability to even download and share in 8K.
LTO tape archive is still the best method for long term archival of content. Always use the latest LTO tape format available when archiving. Secondary drive archive can also be used if desired.
Final versions of content/projects should always be double archived and migrated every year if possible and stored in separate locations to insure longevity and projection of the backup.
