AJA Video Systems released new v3.0 firmware for its FS4 frame 4K/UltraHD and multi-channel HD synchronizer and up/down/cross converter. Loaded with new feature improvements, the free update offers production professionals support for advanced HDR workflows; increased frame buffering depth from 6 to 20 frames; enhanced ancillary data management; and improved overall usability.
   

During the pandemic, expanded use of augmented reality and virtual cameras that require additional processing time surged for live productions, demanding longer synchronization periods for other sources. Incorporating the same enhancements as AJA FS-HDR, the FS4 v3.0 update increases the device’s frame buffer depth to support configurable delays of up to 20 frames. This free update is available to all FS4 users and does not require a hardware change.

As HDR productions are on the rise, the need for better VPID management is mandatory.  Many pieces of equipment in the signal chain ignore or delete this now critical information.  FS4 v3.0 offers the ability to configure the HDR components of the SDI output VPID on a channel-by-channel basis, which has proven vital to workflows that require a consistent and correct VPID. If utilizing the monitor output, overwriting the SDI VPID also overwrites the HDMI EOTF and Colorimetry infoframes. To further assist with HDR workflows, FS4 v3.0 also includes new HDR test patterns and an improved Web UI status page to display more VPID information.

Additionally, Enhanced Single Channel Mode (ESC) offers simultaneous 4K/UltraHD and 2K/HD outputs where the 2K/HD output can have its own unique down-conversion applied. In this mode, processing can be performed on a true 4K or UltraHD signal, and a down-converter is available for HD or SD needs via the SDI monitor output.

“AJA remains committed to helping our customers tackle new production challenges head-on by advancing the capabilities of our tools via continued firmware updates, with FS4 v3.0 an example of integrating user feedback,” said AJA President Nick Rashby. “The latest update addresses key user requests, and delivers a host of new features to help professionals keep pace with modern demands in the field.” 

The update FS4 v3.0is available as a free download from the AJA support page.
