AJA Video Systems 为其强大的实时 HDR/WCG 转换器和帧同步器开发了 FS-HDR v4.1 固件升级版本。作为一个免费的固件更新其主要包括：将帧缓存深度从 6 帧增加到 20 帧、升级了 v1.5 BBC HLG LUTs、增加了全新的 NBCU LUTs、扩展了 CC 字幕支持、以及针对关键辅助数据的传递或转换功能——甚至在 FS-HDR 执行转换的同时也可实现此功能。
在疫情期间，由于现实和虚拟摄像机的广泛使用，使得现场制作所需的额外处理时间激增，视频源需要更长的同步周期。作为应对，FS-HDR v4.1 增加了设备的帧缓存深度，以支持最多 20 帧的可配置延迟。所有 FS-HDR 用户都可以免费使用这个更新，无需对硬件进行更改。
对于那些希望简化 HDR 工作流程并利用 BBC HLG LUT 开展工作的制作人员来说，FS-HDR v4.1扩展了对v1.5 BBC HLG LUTs的支持。最新发布的v1.5 BBC HLG LUTs添加了两个新的LUT：用于SDR BT.2020转HLG BT.2100的直接映射和上映射转换；以及提升了HLG BT.2100 转 SDR BT.709 下映射转换显示光的色彩饱和度。
FS-HDR v4.1 还增加了对全新 NBCU LUTs 的支持，该 LUT 是由 NBC 环球传媒有限公司与 Cromorama 合作开发的，它使得单机同时制作 HDR 和 SDR 的工作流程具备更高的质量。NBCU LUT 包括 SDR、HLG 和 PQ LUT，在最大限度地提高了 HDR 动态范围和色彩容量的同时，不影响核心 SDR 播出。
为了响应行业需求和用户反馈，FS-HDR v4.1 为各种格式和转换增加了辅助数据传递或转换功能。在需要使用 SCTE-104 标记进行广告插入的传输应用中，FS-HDR 现在将自动传递 SCTE-104 包。FS-HDR 的全新 Timecode Xlator 将传递或转换辅助时间码 (LTC、VITC1或VITC2)。此外，FS-HDR v4.1 还扩展了支持 CC (隐藏式字幕)传递的转换集。

Up-Conversion
Hardware 10-bit
Zoom 14:9: results in a 4:3 image zoomed slightly to fill a 14:9 image with black side bars
Zoom Letterbox: results in image zoomed to fill fullscreen
Zoom Wide: results in a combination of zoom and horizontal stretch
to fill a 16:9 screen; this setting will introduce a small aspect ratio
change
Down-Conversion
Hardware 10-bit
Anamorphic: fullscreen
Letterbox: image is reduced with black top and bottom added to image area with the aspect ratio preserved
Crop: image is cropped to fit video output format
Aspect Ratio Conversion for SD to SD
Letterbox: Transforms SD anamorphic material to a letterboxed image
H Crop: Produces a horizontally stretched effect on the image; transforms anamorphic SD to full frame
SD Pillarbox: Produces an image in the center of the screen with
black borders on the left and right sides and an anamorphized image in
the center
V Crop: Transforms SD letterbox material to an anamorphic image
