Kona Film Goes into Public Beta

Free update to support 24 fps By Dave Nagel
Blackmagic Design has released a public beta of new software for the AJA Kona SD board. Kona SD is a video capture and editing board for Final Cut Pro. The new software, which will be a free update for current users after the public beta period, now provides support for editing in 24 frames per second.

The new Kona Film option includes an inverse telecine process, which removes the 3:2 pulldown added to the video by the telecine film scanner. (The pulldown removal is handled as the media is captured to disk.) According to Blackmagic, it provides "clean, artifact-free 24 frame per second [progressive] video on the user's disk." The Kona Film option uses the 23.976 frame rate for compatibility with NTSC video's 29.97 frame rate.

The new software also provides 24 frame playback with 3:2 pulldown insertion to NTSC video. Kona Film also includes a low-resolution playback capability, which lets editors reduce the vertical resolution of video. This adds letterboxing without the
rendering and storage requirements of adding the unused black bars above and below the letterboxed video image, according to Blackmagic.

The Kona SD board itself is manufactured by AJA Video Systems and provides real-time playback and fully digital SDI capture of 10-bit uncompressed video (as well as 8-bit uncompressed, JPEG and DV). It also supports six channels of 48/96 kHz AES/EBU audio. Future updates will include additional audio channels and 64-bit RGB rendering and preview. The board itself id available for $3,295.

Kona Film 24 frame support is available at uncompressed 10 bit, uncompressed 8 bit, and Online JPEG video quality modes. The beta software will be e-mailed to all currently registered Kona SD users. The software and board support Mac OS 9 and Mac OS X. For more information, visit or
