3.2.4. Interpolation Settings

Introduction

The Interpolation settings are available on the Server tab in the server-based application

page) and web-based application in the advanced mode.

The Interpolation settings are highlighted in the screenshot of the server-based application

shown below:

General Description

The interpolation process aims at reducing the vertical jitter of the pictures that is present

during slow-motion replays. This vertical jitter is actually caused by a violation of the

frame parity when playing back the pictures at less than 100 % speed.

The process consists in re-building new frames to produce a more transparent result.

These frames have to be interpolated, that is calculated by making suitably weighted

averages of adjacent lines.

There are two interpolation modes: 2-line interpolator and the 4-line interpolator:

• The two-line interpolator reduces the vertical jitter, but also the vertical bandwidth.

• The four-line interpolator makes it possible to have perfectly steady pictures, but

reduces even more the vertical bandwidth.

Note

All VTRs use interpolation in PLAY VAR mode.

Vertical Interp. (Vertical Interpolation)

Description Enables or disables the two-line interpolation process.
