Linear Editing – The linear video cut finds its roots in analog video. The finished video clip is
usually in the same order as the original video material. A simple example of linear editing is
transferring data from an analog video camera and leaving certain scenes or sections out. But
should you want to insert a new clip e. g. in the middle then all the following clips have to be
re-recorded.
Luma Keying – In contrast to Chroma Keying the transparency of the video based on the
brightness is determined by Luma Keying.
Luminance – Luminance represents brightness in YUV. (Y)
MiniDV – The consumer version of DV formats. See also DV.
MJPEG – Motion JPEG is a compressions technique where every frame in the video data flow is
individually compressed.
MPEG – The Motion Picture Experts Group is a combination of leading manufacturers and
developers of video technology that have led the way to new video standards such as MPEG 1
or MPEG 2.
Non-linear Video Editing – different from the linear video cut the process of adding clips has
no effect on the following clips. The non-linear video cut allows, for example, a clip at the
beginning of a video project to be shortened or removed without having to re-process the
following clips.
NTSC – NTSC is the video standard used in the USA or Japan. NTSC offers a higher frame rate
as PAL (30 frames, i.e. 60 -> half frames per second), but in a lower resolution (525 lines, 480
visible). The color in NTSC standard is represented in YIQ.
Overlay – refers to the transitional effects between two video clips.
PAL – Is the common video standard in Europe. The PAL frame rate is 25 frames (i.e. 50 -> Half
frames) per second and the resolution is 625 lines(576 visible). The PAL color standard is YUV.
Preview – allows a simple overview to help manage your project. The final quality is normally
much better than the preview.
RAM – Random Access Memory is quick working memory of the PC. It is crucial when editing
video with effects and so the general rule: You can't have too much RAM!
Rendering – describes the processing of video or audio clips that have been changed e. g. by
applying filters or effects.
RGB Color Spectrum – In the RGB spectrum every visible pixel is comprised of three
components: R(ed), G(reen) and B(lue). In order to achieve a natural color spectrum on the PC
