TIFF
Tagged Information File Format. A versatile bitmap graphics format. Files have the

timecode
The location of a video frame relative to the start of the video. Timecode values
generally use the format hh:mm:ss:ff (hours:seconds:minutes:frames).

finishes and the next one starts — or can involve digital effects such as fading the end
of the first slide into the beginning of the next slide.
VBR
encoding
Variable bit-rate encoding. A method of encoding MPEG video streams by allocating
more bits to complex sections of video and fewer bits to less-complex sections. This
results in higher quality video than
CBR encoding at the same overall bit rate, or the
same level of quality as CBR encoding at a lower overall bit rate.
VBV
Video buffering verifier. This MPEG video encoding parameter sets the maximum
number of bits that can be used to encode a single video frame. If a video file contains
a frame that exceeds this figure, DVD players may not be able to decode the frame.
VIDEO_TS
The file directory on a DVD disc (or in a DVD Volume folder) where DVD-Video
data are stored.
VOB file
Video object file. The basic media file of the DVD-Video format. VOB files contain
multiplexed video and audio.
WAVE
audio
Uncompressed or compressed digital audio file format developed by Microsoft
Corporation. Files have the extension .

widescreen
Generally used to describe TVs that can display full 16:9 aspect ratio images.
WMA, WMV
Windows Media Audio and Windows Media Video. Proprietary audio and video file
formats developed by Microsoft Corporation and based on MPEG-4 compression
standards. WMA and WMV files can be copy-protected, which prevents them from
being used on any device that is not licensed to play them. Such copy-protected files
cannot be used in DVDit Pro HD projects.
