Update preview rendering
Preview rendering is effective only as long as no changes are made to the pre-
rendered area. You can recognize a pre-rendered area from the green bars appearing
above it on the timeline. As soon as an object in the section has been edited, the
green bar will turn red. You can update this section at any time.
1. To do so, place the playback marker inside the section to be updated.
2. Click on the "Preview rendering" button.
3. In the preview rendering dialog, select "Range" in order to update just the
section selected by the playback marker. If you select "All", all non-rendered
(red) sections will be rendered.
Video effects in the Media Pool
Video effects in the Media Pool can always be opened independently from the
selection of an object.
The program monitor displays the starting image of the video. The playback marker
enables you to jump to a specific position in the video in order to check the results of
the effects by starting and stopping playback.
Brightness & contrast
Auto-exposure: This button automatically optimizes the exposure, contrast, and color
with a few clicks. The other settings options in the dialog provide more precise results.
Brightness/Contrast: Use the sliders to increase or reduce the brightness and the
contrast of the picture.
Gamma: "Gamma" specifies the mean gray value provided by the various color
ranges. In the preset list, select various envelope curves to edit only the dark, median,
or brightest areas of the image.
The fader also sets the intensity of the brightening or darkening.
