Reality 4.27 includes the HAP codec plugin, and it must be enabled for GPU accelerated encoding. Movies that are encoded with the HAP codecs are typically exported into standard *.mov or *.avi. There are four different flavors of HAP to choose from when encoding your clips:
| Codec Format | Description |
| HAP | Has the lowest data-rate and reasonable image quality. |
| HAP Alpha | Has the same image quality as HAP, and supports an Alpha channel. |
| HAP Q | Has improved image quality, at the expense of larger file sizes. |
| HAP Q Alpha | Has improved image quality and an Alpha channel, at the expense of larger file sizes. |
The HAP codecs are designed to fit the needs of a variety of real-time video workflows where the ultra-high-resolution video is needed such as live event production. Along with the ability to work at extremely high resolutions, the HAP codecs also include pro video features like alpha channel support and high-quality modes.
