Field-Order settings
Mercalli offers the following Field-Order settings: Auto / Progressive / Lower Field First /
Upper Field First.
The default setting is Auto (automatic detection of the video).
1. Auto (default):
Auto means that the information contained in the video is automatically read.
Warning:
Some codecs store incorrect information or none at all, and automatic detection may fail as a
result. This may lead to incorrect stabilization. If this occurs, the correct field order must be
selected manually to achieve optimum results.
2. Progressive
Progressive denotes a video stream (clip) made up of full frames as opposed to an interlaced
video stream, which uses sets of fields (Lower Field First or Upper Field First).
3. Lower Field First
Interlaced video consisting of 2 sets of fields. With Lower Field First the fields are displayed
starting with the first field.
4. Upper Field First
Interlaced video consisting of 2 sets of fields. With Upper Field First the fields are displayed
starting with the second field.
Please note:
If a series of vertical spikes appears during video analysis (high-frequency oscillation), it is highly
likely that the Field-Order (Lower/Upper) is incorrect. If this occurs, please select the appropriate
setting in the Field-Order menu (Lower Field First or Upper Field First).
