Timeline Editor

Add graphics to a video timeline with the Timeline Editor.

  • Search for a video using the Search Media editor and open it in the Timeline editor.

  • When using data elements (graphics), the Timeline editor will add them as placeholders on the video timeline. The placeholders will display snapshots of the graphics as video overlays (fetched from Preview Server), and can be manually adjusted on the timeline.

  • A story item containing clip and graphics references from the Timeline editor appears as a group in the playlist. Issuing a Take command on the group triggers the video clip and timed graphics.

Multiple Tracks in the Timeline Editor

images/download/attachments/37572985/userinterface_timelineeditor_controlbar.png

  • The Timeline editor supports multiple tracks for transition logic scenes. This allows graphics to overlap and play out correctly, but requires that all data elements are based on the same transition logic set.

  • The tracks reflect the layers in the transition logic scene. A track is displayed in the Timeline editor if an element using that layer has been added.

  • Graphics from the same layer should not be overlapped, and the Timeline editor will indicate a possible conflict by coloring the graphics placeholders red.

Inline TimeCode Monitor

In addition to the basic TC Monitor that opens in a separate window, an inline TimeCode Monitor becomes available above the local Preview panel in Viz Trio when playing a video. It displays the channel associated with the video and the video’s name in this format: <channel-name>: <clip-name>.

It also displays a progress bar showing how much of the video has played. The progress bar is green when the video is playing, yellow when it is paused and red when 10 seconds remain in the video.

Working with the Timeline Editor

This section covers the following topics:

Adding Graphics to a Video Clip Timeline

  1. Drag a video from the Search Media editor to a playlist.

    Note: The video must be dragged to a playlist in order to add graphics and create a composite element. Graphics cannot be added to videos that are dragged to a page list.

  2. Double-click the video item.

  3. To add graphics, drag an item from the page list to the timeline. A graphics placeholder will appear on the timeline.

  4. Use the mark-in/mark-out points to adjust the duration of the animation.

  5. Optional: Repeat steps 3 and 4 to add more graphics.

    Note: Although graphics may be overlaid on the timeline, graphics that use the same layer (front, middle, back or transition logic layer) will not play out correctly.

  6. Click Save in the upper right corner to create a new composite element, consisting of both the video and graphics.

    • The composite element is presented in the playlist with the video element as parent, and the graphics items as children.

Editing a Composite Element

  1. First, create a composite element, consisting of both video and one or more graphics items, see To add graphics to a video clip timeline.

  2. Double-click the composite element in the playlist.

    • The item will open in the Timeline editor.

  3. Drag graphics to the timeline.

  4. Click Save as in the upper right corner to update the composite element.

Setting the Mark-in and Mark-out point

  1. In the Timeline editor, scrub the cursor to the desired frame.

  2. Click the Set Mark-in images/download/attachments/37572985/userinterface_timelineeditor_markin0.png or Set Mark-out images/download/attachments/37572985/userinterface_timelineeditor_markout0.png button.

Click Jump to Mark-in images/download/attachments/37572985/userinterface_timelineeditor_jumpmarkin0.png or Jump to Mark-out images/download/attachments/37572985/userinterface_timelineeditor_jumpmarkout0.png to view the points.

Troubleshooting and Known Limitations

Video Codecs

If you are previewing proxy versions of video clips from Viz One using the Timeline editor you must install video codecs that are not part of the basic Viz Trio installation. Note that the setup procedures of Settings are only relevant when using the Timeline editor and not Viz Trio as such. Playout of high resolution versions on Viz Engine does not require these codecs.

Viz Engine Configuration

In order to work with video clips from Viz One in the Timeline Editor, Viz Engine must be configured accordingly.

Known Limitations

  • Although graphics may be overlaid on the timeline, graphics that use the same layer (front, middle, back or transition logic layer) will not play out correctly. The Timeline editor will always indicate a possible conflict by coloring the graphics placeholders red. To use overlapping graphics based on transition logic scenes, see Multiple Tracks in the Timeline Editor.

  • Current limitations on the Media Sequencer will cause the following behavior:

    1. If you issue a Take on a timed group (1), and while that group is being played out issue a Take on graphics in another layer (2), the Media Sequencer will instead take out the last taken element (2) when issuing the timed Take Out command (for the timed graphics).

    2. Hence, it is currently not recommended to take other data elements on-air while a timed group is being played out.

  • The Timeline editor may behave unexpectedly in some virtual machine or remote desktop environments.
