Still Image Export

In order to export a still from a clip, simply move the playhead to the desired frame within the clip and select “Clip > Create Still Image” from the main menu as shown in here:

Batch Export of Still Images for Multiple Clips

Additionally, Silverstack can export multiple still images at once. That’s possible by either selecting multiple clips in the timeline from the Playback View or within the Table or Collection Views.

Depending on the context in the software, the still frame position used is different:

  • Playback and Timeline View: Silverstack exports the Current frame in the playhead of each selected clip (indicated by the timeline ruler).
  • Table & Collection View: Silverstack exports the same Thumbnail image displayed in the Table and Collection View.

Note: Have in mind that it’s possible to set the position for the creation of thumbnail images through the Preferences menu. That is going to allow the export of still images based on the same position while the Table & Collection View is active. Learn more about setting the position for the creation of thumbnail images in the article Choosing Custom Thumbnail Images.

Still Image Export Settings

Global Preferences vs. Still Image Export Preset

Silverstack offers two methods for exporting still images:

  • 1. Using the still image settings from the Global Preferences (default)
  • 2. Using the still image settings from the Still Image Export Transcoding Preset (Silverstack XT only)

1. Using the Settings from the Global Preferences

There are multiple settings and formats available for the still image export feature in the Preferences menu, under the Projects tab:

Preferences menu: Still image export settings

The following options and actions are available:

  • Store Exported Still Images To: Choose the directory to store your still grabs on your system by clicking the “Choose…” button.
  • Naming Scheme: With the naming scheme you can define the naming for the exported still image files.
    • There are multiple preset options available:
    • In addition, the “Custom:” option allows users to build a file name based on the metadata of the clip the still is exported from. By clicking “Customize…” you can open the metadata wildcards panel and choose from the available wildcards to build a custom file name scheme: 
  • Image Format: The available image formats for exporting frames are:
    • JPEG – 8-Bit, 90% Quality
    • TIFF – 8-Bit, Uncompressed
    • TIFF – 16-Bit, Uncompressed
  • Color Mode: The different color modes are:
    • As currently shown in player
    • Original color
    • Both: Exports two images with both of the above settings – one as shown in player and the other with the original color.

 

2. Using the Settings from the Still Image Export Transcoding Preset

In order to activate that mode, users have to select the option ‘Use the still image settings from: Still Image Export Transcoding Preset‘:

Preferences Menu: Still image export settings

Once that setting is enabled, the ‘Still Image Export‘ preset is going to appear in the Presets panel of the Transcoding Configuration menu:

Transcoding Configuration Menu: Still Image Export Transcoding Preset

      • In addition, the “Custom:” option allows users to build a file name based on the metadata of the clip the still is exported from. By clicking “Customize…” you can open the metadata wildcards panel and choose from the available wildcards to build a custom file name scheme:

      • Note: The «Custom Text» burn in option (Silverstack Lab only) allows to add metadata wildcards into the custom text field. For instance, it’s possible to display «Scene: [scene value]-[shot value]» as shown in the following figure by writing «Scene: $scene$-$shot$» in the custom text field.Find a list of all available keys in the article Custom Burn-In Wildcard Keys.
