Roll / Pan Shot / G-Force / CMOS-Sensor / Cam-
Limiter / History
Below the Preview in Mercalli, various graphical instruments are displayed, which show the
different characteristics of the stabilized video during playback.
1. Roll
The Roll-Instrument shows the necessary roll movement correction of the video.
2. Pan Shot
The Pan-Instrument shows the necessary Pan movement correction of the video.
3. G-Force
The G-Force-Instrument shows the acceleration of the needed Pan correction.
4. CMOS-Sensor = Rolling Shutter Effect
The CMOS-Sensor-Instrument shows Rolling-Shutter problems produced from CMOS-sensors used
in pocket cameras, DSLR cameras or low price camcorders
The rolling shutter effect is a form of distortion that can occur in moving footage.
The fully automatic Rolling-Shutter Compensation corrects the weaknesses inherent in CMOS
sensors in post-production, thus enhancing the quality of footage from action cameras, compact
photo cameras, mobile phones and, not least, digital SLR cameras.
5. Cam-Limiter
Shows the overall stabilization level. Intensive corrections are being ignored in order to avoid
zoom-in as best as possible. The balance for maximum stabilization or minimal zoom those
intensive corrections can be set using the slider Avoid Border.
6. History
Shows the correction history of movements and their directions (red=current stabilization,
cyan=original state).
