De-fragment When a hard drive has many new files added or old files
modified, moved or deleted, often the organization of the file structure
becomes severely discontinuous or 'fragmented'. De-fragmenting your drive
makes these broken-up files continuous and moves them closer together for
faster access.
Drop Frame A method of compensating for an arithmetic error caused by the
color TV signal recording system. In black and white days, TV was precisely
30 fps; when color was invented for USA TVs (NTSC), the Frame Rate (now
29.97 fps) had to be slightly altered to allow for the color system to work. Drop
Frame timecode accounts for this slight change by displaying 30 fps, but
dropping two frame numbers (not images) every minute of video, but not at
every 10th minute (this is where you can slap yourself on the forehead in
frustration).
FAT32 The structure for file storage on large Windows hard drives created by
Microsoft. FAT32 (File Allocation Table 32 bit) allows for hard drive partition
sizes up to 2 terabytes, but individual file size is limited to 4 gigabytes.
Fields The method by which video images are assembled to increase
perceived temporal and spatial resolution. Each image of a video frame
consists of two clusters of alternating horizontal scan lines, where the image is
split in half, then transmitted as these split 'Fields'. Upon reception, the 'Fields'
are interlaced, forming a whole frame.
Gamut The distribution or extent of a Color Space. The amount of colors a
system can display.
Interlacing The stitching of alternating scan lines of a field-recorded video
frame. First, the frame is displayed at half resolution, then the remaining
missing field is 'interlaced' into the first field's missing scan lines, forming a
complete full-resolution image frame.
Interpolation A calculation done to determine a missing value existing
between two known values.
Keyframe/s A specific instruction or point in an animation where some form
of event occurs. Keyframes are indices where the animator wants the computer
to begin, continue, or end its interpolation or translation of a motion or effect
sequence.
