Interlace
For historical reasons, pictures in a movie are always recorded and transmitted in the form of two fields;
first the lines with even numbers and then those with odd numbers. These fields are alternatively displayed
with double the frame
rate. The (lazy) eye of the viewer or the processing of the TV tube puts the two frames together to form
one.

First field
Second field
You normally don't have to worry about field processing. The video material goes through the entire
processing chain as fields and is exported again as fields or burned onto DVD or shown on TV when
played back on a DVD as a full picture. Only in certain rare conditions is it necessary to go deeper into
this process. Two problems can occur:
1. Interlace artifacts
To be displayed on a computer monitor (during recording, in your TV/VCR, and in the arranger during
editing), the two fields must be combined to form a full screen.
These two fields are not the same, since two fields are created during the recording between which a
1/50 of a second gap is evident. Moving objects can therefore produce artifacts on vertical edges.
Typical interlacing errors
You can use so-called de-interlacing to avoid this type of artifact. De-interlacing places a picture in
between the two fields (interpolated). If you want to create stationary pictures from movies, then you
should definitely use a de-interlace filter.
In the system settings ("File" menu -> Program settings) you can set the preview monitor display to use
hardware
de-interlacing during video recordings for the video recorder and for display in the arranger.
2. Incorrect field rate
If you move around the series of fields in a movie data stream, then you will see strong jitter and flicker
effects. Picture objects move in a backward movement ? two steps forwards, one back ? since a
delayed field is shown before the previous one. This can happen in the processing chain if you export
video material improperly with the wrong field order and then import it into different material. We use
MXV or MPEG
"Top field first" format for all analog recordings ("odd" in other programs).
DV-AVI
on the other hand is saved with "Bottom Field First".
You can correct the field series for each video object in its object settings. See: "Menu
-> Effects -> Object properties"
