existing pixels is converted to a smaller or greater quantity, depending on the magnification
ratio. Suitable median values are formed from the color transitions between the original pix-
els.
The quality of the interpolation process determines the resulting image quality.
Lanczos interpolation
Lanczos interpolation is an alternative to bicubic interpolation, but it is very similar. With this
method new pixel values are calculated based on a weighted sum of the relative position of
the the original pixels. Weighting is determined with the aid of an iterative algorithm devel-
oped by Cornelius Lanczos.
This interpolation method generates relatively strong sharpening and offers higher quality.
Letterbox
Letterbox is a process for adapting a format by e.g. compressing a video file from 16:9 for-
mat to the television format 4:3. The picture is limited at the top and bottom of the screen
with black bars.
Macroblock
A macroblock describes 16 x 16 pixels and is the elementary unit in the MPEG standard on
which motion coding is also based.
Macroblock level
The macroblock level describes the type and position of a macroblock in the image.
MPEG
MPEG stands for Motion Pictures Experts Group and is a way to compress video and audio
files.
Multithreading
The capability of a process to work through several editing threads at the same time. In the
software area, calculation of a process can be distributed amongst multiple system proces-
sors.
P-Frame
P-frames (predicted frames) are predicted images in the MPEG compression. They are
based on predictions and suppositions from previous intra frames (I-frames) and predicted
frames (P-frames). They contain only the modification information on the previous image.
Since P-frames have a higher compression rate than I-frames, the compressed data volume
is less.
Plug-ins
A plug-in is a small extra program that adds features to a higher-order program.
Quantization
Quantization is part of the digitalization of analog signals. The analog signals are scanned at
regular intervals, and at each of the scan times their voltage values are converted to digital
values. This conversion to numbers and measurable quantities is referred to as quantization.
