Video Edit Magic: Understanding Link, Lock and Hide Options |
The Link, Lock and Hide option alter the way a track is displayed or selected. These options can be used to selectively edit and preview the timeline. The Link, Lock and Hide buttons form three separate columns across the length of the timeline at the left edge of the timeline. Each track, except the volume track, contains all the three options. The Volume Tracks lack the Link Option. These options for a track can be toggled by clicking on the respective option for the track under consideration.
The Lock Option forms the first column and the first option for every track in the timeline. When a track is locked, an image of a door lock is displayed and any sources in a locked track appear disabled (grayed). Volume graphs in a volume track also appear grayed.
The Lock option is used to prevent accidental editing. Drag, Cut, Copy, Paste, Delete, Crop, Move and Resize (All editing operations) do not affect locked tracks. No sources can be moved in or out of a locked track. A locked track cannot be selected.
The Hide option forms the second column and the second option for every track in the timeline. Enabled video, effect and transition tracks are shown with an eye image and enabled audio and volume tracks are shown with an audio image. No image is shown when a track is hidden.
Hidden tracks remain in the timeline but are not shown in the preview. This option is very important when the timeline is to be viewed without a particular track without deleting the contents (sources) in that track. For example to preview the timeline without the effects, hide the effects track or to preview the timeline without the audio, hide the audio track. The Hide option is particularly important to turn off volume variations.
The Link Option forms the third column and the third option for every track except the volume tracks in the timeline. The volume tracks do not have the Link option. A linked track is shown with a chain link image. No image is displayed when the tracks are not linked.
Tracks that are not linked are not selected during range selection (when selection sliders are visible). The Link option can therefore be used to selectively edit sources in a track. The sources can however be selected when the selection sliders are not visible irrespective of the Link state of the track. The Link option also affects the way the timeline responds when a source is dragged and dropped.
