example, if Video1 and Audio1 are locked, it will automate to Video 2 and Audio 2, or the lowest audio track with the correct channel type.
Clip Overlap Specifies the duration of the transition and how much to adjust the clips’ In and Out points to compensate for it when Apply
Default Audio Transition or Apply Default Video Transition is selected. For example, a value of 30 frames trims the clips’ In and Out points
15 frames at each edit, where a 30-frame transition is added. The default value of this option is 15 frames. A menu lets you set the units to
frames or seconds.
Apply Default Audio Transition Creates an audio crossfade at each audio edit, using the default audio transition (defined in the Effects
panel). This option is available only when audio tracks are present in selected clips, and the Placement option is set to Sequentially. It has
no effect when the Clip Overlap option is set to zero.
Apply Default Video Transition Places the default transition (defined in the Effects panel) at each edit. This option is available only when
the Placement option is set to Sequentially, and has no effect when the Clip Overlap option is set to zero.
Ignore Audio Ignores the audio in clips selected to be automated to the sequence.
Ignore Video Ignores the video in clips selected to be automated to the sequence.
The Adobe Tutorials website has this article
about the Automate to Sequence command and storyboard style editing called "Edit
Storyboard Style.”

Mixing clip types in a sequence
You can mix clips with different frame rates, frame aspect ratios, and frame sizes in the same sequence. For example, if you drop an HD clip into a
sequence in an SD project, the clip will be letter-boxed and scaled to the SD frame size automatically. Similarly, if you drop an SD clip into a
sequence in an HD project, the clip will be pillar-boxed automatically.
A render bar will appear above any clip in a Timeline panel with attributes not matching the sequence settings. The render bar indicates that those
clips will have to be rendered before final output. However, it doesn't necessarily indicate these clips can't be previewed in real-time. If a yellow
render bar appears above the clip, Premiere Pro can probably play it back in real time without rendering. If, however, a red render bar appears
above the clip, Premiere Pro probably can not play it back in real time without rendering.
A clip with a frame rate different from the frame rate of the sequence will play back from a sequence at the frame rate of the sequence.
Replace one clip with another in a Timeline
You can replace one clip in a Timeline panel with another from the Source Monitor or a bin, retaining any effects that were applied to the original
clip in a Timeline.
Using one of the following keyboard modifiers, drag a clip from the Project panel or Source Monitor onto a clip in a Timeline panel:
To use the In point of the new clip, Alt-drag (Windows) or Option-drag (Mac OS). You may use the In point of the new clip, for example, if
you have already trimmed it to start at the desired point of the action.
To apply the In point of the original clip to the new clip, Shift-Alt-drag (Windows) or Shift-Option-drag (Mac OS). You may apply the In point
of the original clip to the new clip, for example, if the new clip was shot synchronously with the original clip using another camera. In this
case, applying the In point from the original clip will start the new clip from the same point in the action.
In a Timeline, clip position and effects are preserved, and any effects that were applied to the original clip are applied to the replacement clip.
You can also replace a clip in a Timeline by selecting it, selecting a replacement clip in a bin or the Source Monitor, and then selecting Clip >
Replace With Clip > [replacement type].
Replace the source footage for a clip
You can replace the source footage for any clip in the Project panel. Replacing the source footage for a clip links it to a new source file. All
instances of the clip and its subclips are retained in the Project panel and Timeline, with their In and Out points, and any applied effects, intact.
However, the clip becomes linked to the replacement footage instead of its original footage. You can easily replace, for example, placeholder
footage with final footage, or footage with a soundtrack in one language with identical footage with a different-language soundtrack, and keep all
the same edits that were made with the original footage.
1. In the Project panel, select the clip for which you want new source footage.
2. Select Clip > Replace Footage.
3. In the Replace Footage For dialog box, browse to the file containing the replacement footage.
4. To rename the clip with the replacement footage filename, check Rename Clip To Filename.
5. Click Select.
