Frame Memory 7 Chapter Overview A frame memory is a function that freezes and captures a single frame of the input video feed as a still image for later use. You can also specify a range in the input video to create still images to form a frame memory clip. Note Installation of the XKS-8440 Frame Memory Board is required to use the frame memory function. Frame memory storage area There are two storage areas on the frame memory board. Memory: Volatile memory used for operation. When the system is powered off, files and folders in memory are lost. Storage: Non-volatile memory for storage. This space is used for storing created image data files. When used for frame memory operations, the target file is loaded into memory. Note After loading a file, performing a file operation in storage, such as renaming or deleting, will delete the file from memory. Image data storage capacity The number of images that can be stored in memory is given below. Signal format • 3840×2160P/59.94 • 3840×2160PsF/29.97 • 3840×2160P/50 • 3840×2160PsF/25 • 3840×2160PsF/24 • 3840×2160PsF/23.98 Storage capacity Approx. 1,300 Approx. 1,100 Signal format • 1080P/59.94 • 1080i/59.94 • 720P/59.94 • 720P/50 • 1080PsF/29.97 • 1080P/50 • 1080i/50 • 1080PsF/25 • 1080PsF/24 • 1080PsF/23.98 Storage capacity Approx. 5,500 Approx. 4,600 Approx. 4,400 Frame Memory Image Data The following two types of image data can be manipulated in frame memory. When there is no distinction being made between image data types, image data is referred to as just an "image." Still image: A single image in the input video is frozen and saved. Each file (still file) holds just one still image. Clip: A clip is created by a series of still images, which is played back like a video. The collection of files constituting a clip is referred to as a "clip file." Notes on saving or recalling a frame memory in a snapshot/keyframe • Only still images and clips recalled to FM outputs (FM1 to FM20) can be the target of snapshots or keyframes. • If a frame memory is recalled due to a snapshot or keyframe, the still image or clip must exist in memory under the same conditions as when it was saved. Load the target image in memory beforehand so that it is available for use when the recall operation occurs. Frame memory input and output There are two lines for frame memory input: frame memory source 1 bus and frame memory source 2 bus. There are 20 frame memory output channels, FM1 to FM20, and each channel independently allows an image to be saved or recalled. By assigning FM1 to FM20 to crosspoint buttons you can use the image output from each channel as input material. 169
