Everything you wanted to know about markers in Premiere Pro. YouTuber, Chinfat, talks about markers in-depth in this episode of his Premiere Pro CC 2017 tutorial series. He starts off by showing what markers are, and how sequence and clip markers are different. At 5:34 Chinfat covers one of his favorite marker features: in and out points. This can be done by Option (Alt) clicking on markers or by modifying the duration field in the Marker inspector window. Markers can also be color coded, which Chinfat demonstrates at 7:54. He also shows how to search sequence or clip markers by color and text in the Marker panel at 8:50. Chinfat's tutorial is so thorough, at 10:47 he even explains how markers are saved to XMP files, which are stored in Premiere Pro's Media Cache Database. These settings can be controlled under Preferences. Finally, at 12:33 Chinfat shows how to enable Ripple Sequence Markers under the Markers menu. This setting is critical if you're making edits and want your markers to stay in sync with your clips. This is a long tutorial, but you'll walk away with a deep understanding of markers in Premiere Pro. Mark my words.
