5.0 ON-BOARD RECORDING – IN EITHER XF-AVC OR ProRes
As shown in Figure 7 the on-board primary recording uses two CFast memory cards to record
any of the chosen 4K / UHD / 2K / HD production formats. At the same time a proxy version for
offline editing support is recorded on an SD card at a much lower data rate.

6.0 INTRA ProRes MODE
Three levels of ProRes are available that offer a range of choices in recording data rate:
Apple ProRes 4444: High-quality version of Apple ProRes for 4:4:4:4 image sources
(including alpha channels). This codec features full-resolution, mastering quality
4:4:4:4 RGBA color and visual fidelity that is perceptually indistinguishable from the original
material.
Apple ProRes 422 HQ: Higher-data-rate version of Apple ProRes 422 that preserves visual
quality at the same high level as Apple ProRes 4444, but for 4:2:2 image sources.
Apple ProRes 422: High-quality compressed codec offering nearly all the benefits of Apple
ProRes 422 HQ, but at 66 percent of the data rate for even better multistream, real-time editing
performance.
