Does VelocityHD Support the Virtual Tape File System™?
Like all of our Velocity editing solutions, VelocityHD features the Virtual Tape File System (VTFS), providing seamless and transparent interchange between VelocityHD video files and all major graphic file formats. While video data is stored on the system as .LTV video files, the VTFS makes the video data also appear to application programs as sequences of frames in a variety of common image file formats, including TGA, CIN, DPX and JPG. The key is that these frames in these formats don’t actually exist until an application specifically accesses a frame – hence the “Virtual” in VTFS. When an application accesses a specific frame in its preferred format, the VTFS automatically generates that frame in that format from the actual stored .LTV video clip, with no manual conversion steps required. Similarly, an application can save a numbered frame in any of the supported formats, and it will automatically be incorporated directly into the specified video clip, ready for immediate output. Th
