Having a high-level view of how video is stored and displayed in professional environments is necessary for interpreting the benefits of NFS over RDMA. There are other factors not covered here, such as color bit-depth and image dynamic range, but those topics are beyond the scope of this white paper.
Understanding video resolution, frame rate, codec, and whether the material is an image sequence or video file is important. Video files may contain video and audio. These files may be compressed or uncompressed. The file extension (“container”) does not specify how video data within is encoded. Compressed video saves storage space and bandwidth at the expense of increased workstation CPU cycles. Lossy compression does not retain all the original image data. Lossless compression retains all the original image data. Image sequences store video with each frame as a separate file. Some applications work better with image sequences. Image sequences may be compressed or uncompressed. With both types of video data, the higher the resolution and higher the frame rate, the greater burden is put on storage and client CPU.
