> Add to Clip
> ScreenFlow supports timeline markers, but one significant limitation is that they do not adjust to content changes. This means you must manually adjust your markers when you rearrange your timeline. But Clip-based Markers attached to clips solve this problem because they flow with the content and self-adjust.
> To add a clip marker, first select a clip and make sure the scrubber is within the bounds of the clip, then select Mark >Markers > Add to Clip.
> When the popup dialog box displays, enter a name for your marker and click Create.
> The marker can be created without a name. Clicking away from the popup cancels the Add To Clip operation.
> Once the clip marker has been created, it is positioned along the bottom of its parent clip. It can be moved with the mouse to reposition it, and if double-clicked, the marker popup is displayed enabling you to change the name.
> The clip marker works in the exactly as a timeline marker. If it has been given a name, it can provide a chapter marker to YouTube or for QuickTime exports. It will appear in the Markers window (opened by selecting Window > Markers), enabling you to get a quick overview of all markers in the system.
> You can also quickly jump around all markers in the system using keyboard shortcuts. To delete the marker, move the scrubber over it and select Marker > Delete Marker.
