With the functionalities provided within the “Visual Controls” panel you can check the colors and quality of your video clip:

  1. Channels: By selecting one of the three RGB-channels Silverstack shows the distribution of this color in the image of the video clip.
  2. Focus Assist: The focus assist  helps you to detect if your image is in focus by detecting the edges of the image. You can set the sensitivity.
  3. Clipping: With the clipping functionality you can check which areas of your image clip are either in the whites or blacks.
  4. Exposure Range: This option allows you to detect different ranged areas of luminance in your image.
  5. False Color: You can use this option and active false color. The represented values can be found in figure 2
  6. Framelines:  add frame lines to visualize the clips with a different aspect ratio. More information in the article Frame Lines in the Playback View.

Video Preview playback control

The Silverstack playback controls allow you to control the video preview with standard video controls (figure 3 #1) and the possibility to set IN- and OUT-points (#2) as well as to loop the video and zoom into it (#3). To show the original Log gamma instead to the Rec.709 conversion, select the #4 check box.

100% Zoom for Retina Displays

Silverstack is optimized to work with the “Default” settings for Apple retina displays which you can find under “System Preferences > Displays”. Choosing this setting, Silverstack will map 1 media pixel to 1 physical pixel of the display.

This setting is best suited for visual image analysis such as focus or sharpness.
