4.2 Library

Owned by Thomas Staiger
Last updated: May 02, 2018 by Georg Deisting

The Library shows a filtered view of the repository folders defined in just:connect for the this Channel. Each tab shows only the files which match the type of tab.

  • You can navigate the Library like a Finder window (in list view) by using the arrow keys.
  • You can preview Videos by pressing the space bar.
  • To get information about an item, place the mouse over it and wait for a moment.
  • You can hide/show and dock/undock the Library using the corresponding menu options in the View menu.
  • In case there are two Videos with the same name in the same folder but with different extensions, setting a new in/out-point and/or poster frame will apply the new settings for both Videos. Move the Videos to different folders to avoid this.


  1. Video Tab: Lists all Videos from the repository folder(s) defined in just:connect. If a Video does not show up in the list but shows up in the Finder, check if the file ends with one of the supported suffixes: mov, mpg, mpeg, mpegts, avi, mp4, 3gp, m4v, f4v, dv or mxf. Only files with a supported suffix are shown in the Library. Even though just:live displays any avi, .mkv, mp4, mxf and mov file in the Library it is possible that a Video does not play out finally because the correct codec to decode the file is not installed on the system. Contact your system administrator for more information. Videos which do not match the output frame rate are highlighted in red and cannot be selected or added to the rundown. Also you can find the placeholders in the Video tab to switch to the live source, to add a gap to the rundown or to schedule a placeholder item for a Video which is currently not available. 
  2. Audio Tab: Lists all Videos from the repository folder(s) defined in just:connect. MP3, M4A and WAV Audio files are supported at the moment.
  3. Graphic Tab: Lists all Graphic files from the repository folder(s) defined in just:connect. Only Graphic files with one of the supported suffixes are shown: composition, qtz, js, jscomposition, png or jpg.
  4. Event Tab: Lists all Router/GPI Events which have been defined by the system administrator before. Such elements can be scheduled at any time by dropping them into the "Event" Layer in the Timeline. 
  5. Playlists Tab: Lists all previously saved Playlists from the repository folder(s). Playlists can be made using just:play but also Final Cut Pro compliant XML files saved in the Playlist folder will show up here for immediate use. Once a Playlist is dropped into the Workbench, all Videos will have the "play next" finished action assigned to them automatically.
  6. Files: Lists all elements which are available (depending on the selected tab) for Playout on your system.
  7. Metadata Columns: Depending on the selected tab you will see more or less metadata columns. You can rearrange and change the width of the columns by moving the elements in the header area. Metadata elements which are shown in red do not match the current Playout format and will be changed automatically once added to the rundown. Red colored aspect ratio information means that the aspect ratio does not match, red colored codec information means that the field order does not match. Make sure that at least a little bit of a metadata column is visible in the Library, otherwise the metadata will not be read out resulting in a "red" element which can not be added to the Workbench for Playout.
  8. Preview Area: Shows a preview of the currently selected element. Use the right mouse button (or ctrl-click) for more file related functions like the ability to reveal the file in the Finder. Press the space bar to open Quick Look for the selected file.
    • Video: preview the Video, set the in/out-point, define the poster frame. Audio is played out using the system Audio device
    • Audio: Audio files cannot be previewed.
    • Graphic: preview a Graphics file. In case it has a stop frame, the stop frame will be handled like On Air.
    • Event: when activating the Events tab, the preview button changes its functionality and its icon. Clicking the "+" button allows you to build a new Router control/GPI Event. 
    • Playlists: Playlists cannot be previewed.
  9. In/Out-Point and Poster Frame Control: See below.
  10. Search Field: Allows you to search for files and related metadata in the repositories. Click on the magnifying glass to select the metadata column you want to use for the search. 
  11. Control Buttons:
    • Item Sorting Order: Click on this button to change the sorting order (from A...Z or from Z...A) of the selected tab.
    • Open/Close Preview: Pressing the preview button shows or hides the preview area. 
    • Refresh: Click on this button to refresh the content of the Library whenever an element is "red" (no metadata available) or not shown at all. This is especially useful in case your disk storage does not support file system Events and therefore the content is not updated automatically. 


Library: Preview Controls

  • When dragging a Video from the Library into the Workbench, the "active play" area marked in QuickTime Player is used to automatically set the Video's in- and out-point.
  • Defining a new in/out-point and/or poster frame will write this information to the metadata XML sidecar file which has the same name as the Video file. The sidecar files are stored in the same repository as the respective Video files.



  1. Set In-Point (Videos only): Defines the in-point of a Video. Scrub the blue CTI and click on In to define a new in-point.
  2. Go to In-Point (Videos only): Moves the CTI to the in-point.
  3. CTI Position: Shows the timecode of the CTI position.
  4. Go to Out-Point (Videos only): Moves the CTI to the out-point.
  5. Set Out-Point (Videos only): Defines the out-point of a Video. Scrub the blue CTI and click on Out to define a new out-point.
  6. Trimmer and CTI (Videos only): The yellow trimmer is a visual representation of the in/out-point. Using the blue CTI you can scrub through the Video, which allows you to get a better overview.
  7. Control (Realtime Graphics items can also be previewed here. Use the play button to start the preview and to release stop frames. Use the rewind button to jump to the beginning of a realtime Graphic.)
