you can select keyframes rather than entering a length from the TimeMarker panel to put in a mark that crosses the entire period of these selected keyframes. When you put in a split mark to the comp with no remark, the mark's length will look like the remark. This serves as a fast means to assess the length of any cartoon.
"Adobe's Responsive Design -- Time" attribute lets you guard keyframes inside a split mark from being time-stretched if the nested comp is time-stretched. This makes it simpler to fix intro & outro animations for various comp durations.
Select the keyframes you'd love to safeguard and toggle-on that the Protect Region checkbox then clicks on Insert Marker.
Another method to bring a protected placemark is by simply inputting a duration from the TimeMarker panel and toggling-on that the Protect Region checkbox then clicking Insert Marker. This may add the mark to the present period so long as no keyframes have been chosen. If keyframes are chosen the mark is only going to shield the area of selected markers.
Insert a Timestamp
Timestamps begin drawing in the coating's pinpoint and may be made as guide layers by clicking on the checkbox on the left side. Insert as many Timestamps as because you want to measure milliseconds, seconds, or frames.
