Today we are happy to share the fruits of a collaboration with Tom Butterworth that has been in the works for about a year now: Hap, a new video codec designed specifically for digital video artists and Mac VJs with the goal of achieving higher-performance video playback in OpenGL-based applications such as VDMX.
Instead of using the CPU to decode video frames, Hap passes compressed image data directly to your computer's graphics card for hardware accelerated decompression of movies during playback. By shifting this burden from your CPU to your GPU, Hap makes it possible to use more movies at higher resolutions than typical CPU-bound codecs.
Hap comes in three different flavors to meet the needs of real-world usage: Hap, Hap Alpha, and Hap Q. Hap offers the lowest data-rates for playing back the most clips at a time. Hap Alpha is similar to Hap, but adds support for transparency. Hap Q encodes at a higher data-rate to achieve significantly cleaner images when quality is a priority over performance and file size.
