Endian (Little and Big)
Little and Big Endian describe the ordering of multi-byte data that is used by a computer's microprocessor.
Little Endian specifies that data is stored in a low to high-byte format; this ordering is used by the Intel
microprocessors. Big Endian specifies that data is stored in a high to low-byte format; this ordering is used
by the Motorola microprocessors.
Envelopes (Audio and Video)
Envelopes allow you to automate the change of a certain parameter over time. In the case of volume
envelopes, you can create a fade out (which requires a change over time) by adding an envelope and
creating an extra point to the line that indicates where the fade starts. Then you pull the end point of the
envelope down to infinity.
Equalization (EQ)
The process by which certain frequency bands are raised or lowered in level. EQ has various uses. The most
common use for Vegas Pro users is to simply adjust the subjective timbral qualities of a sound.
Essence Marks
Essence marks can be saved in XDCAM clips during shooting. These markers can indicate record start/end
times, shot marks, flash, filter/gain/shutter speed/white balance changes, or audio clipping. In Vegas Pro,
essence marks can be displayed in the XDCAM Explorer and as media markers. For more information, see
"Using the XDCAM Explorer Window" on page 407 and "Using Media Markers and Regions" on page 220.
Event
An event is an occurrence of a media file on the timeline.

File Format
A file format specifies the way in which data is stored on your floppy disks or hard drive. In the Windows
operating system, the most common file format is the Microsoft .WAV format. However, Vegas Pro can
read and write to many other file formats so you can maintain compatibility with other software and
hardware configurations.
Frame Rate (Audio)
Audio uses frame rates only for the purposes of synching to video or other audio. In the latter case, the rate
of 30 non-drop is typically used. In the former case 30 drop is usually used.
