Blackmagic Design DaVinci Resolve Advanced Panel - Manual (Page 178)

COLOR 178
Viewer Stills Display
The first few of the pop-up options relates to stills. ‘Grab Still’ will simply grab the current frame to make
a still and place it in the Gallery Stills display. This still can then be used as a reference for comparison in
other scenes. ‘Grab all stills from first frame’ will grab a still from every clip on the timeline using the first
frame of each clip.
‘Grab all stills from Middle Frame’ will perform the same function except use the middle frame of each
clip as the source of the still. Once this procedure has started, it will continue until completed, which
could take some time.
The ‘Toggle Wipe’ selection will turn the wipe on and off. This function on the DaVinci Resolve control
surface is called ‘Play Still.’ The Toggle Wipe mode will select to compare the current timeline clip to either
the Gallery Still, the matching Offline frame or another clip on the timeline. To use, select a clip on the
timeline, toggle the mode to Timeline and then use the mouse to select the thumbnail of the reference
clip. Right click on the thumbnail to select ‘Wipe Timeline’ and the reference clip will be highlighted in
yellow when you move to the clip to compare.
Alternatively, to compare the current clip to the Offline, select the ‘Still/Timeline’ button on the DaVinci
Resolve control surface until the Offline label is seen on the status display. (More on the Status display
later in this chapter.) You will then be able to perform a wipe with the offline recording in conjunction
with the clip.
The Toggle Wipe Shape option switches between Vertical Wipe, Horizontal Wipe, Mix, or a Key or Alpha
control. (More on this later when we look at green screen keying and display.) Toggle Invert Wipe will
swap the reference and current images in the Wipe display so you can see the other side of the images.
The Reset option will set the image to the normal display for the viewer. The original setting will display
the image pixel for pixel so it is usually used for getting quick zooms to the source image size to look for
imperfections in the original image.
