Copy or duplicate a layer
When you copy a layer, you copy all of its properties, including effects, keyframes, expressions, and masks.
Duplicating a layer is a shortcut with which you copy and paste the layer with one command. Duplicating a layer with a track matte preserves the relative ordering of the layer and its track matte.
When you paste layers, they are placed in the order in which you selected them before copying. The first layer selected is the last one to be placed, so it ends up on the top in the layer stacking order. If you select layers from the top first, they end up in the same stacking order when pasted.
If you have a component of a layer—such as a mask or keyframe—selected when you copy, you copy only that component. Before copying, press Shift+F2 to deselect all of the components of a layer and leave the layer itself selected.
- To copy selected layers and place the In points of the copies at the current time, choose Edit > Copy, and then press Ctrl+Alt+V (Windows) or Command+Option+V (Mac OS).
- To copy selected layers and place the copies at the same times as the originals, choose Edit > Copy, and then choose Edit > Paste.
To place copies at the top of the layer stack in the Timeline panel instead of immediately above the originals, press F2 to deselect the originals before you paste.
- To duplicate selected layers, choose Edit > Duplicate or press Ctrl+D (Windows) or Command+D (Mac OS).
Hi Thanks for your reply!
The issue isn't the positioning of the layer...it's the action of the layer...
I have tried all of the above...same result...elements of the original are not there...as the effect or transform is not the same...
even if i copy-paste the effect and transform after the layer is copied.
Make sure the selection tool (looks like an arrow at an angle) is active by selecting the timeline and pressing the letter v or going to the tool bar and selecting the first tool on the left
Select the layer you want to copy in the timeline. To duplicate the layer press Ctrl/Cmnd + d and a new copy of the layer is created above the selected layer
To copy a layer from one composition to another Select the layer in the original composition
Press Ctrl/Cmnd + C to copy or choose Edit>Copy from the Menu
Select the new composition
Press Ctrl/Cmnd + V or choose Edit>Paste from the Menu to paste the layer you copied in the new composition
That's all there is to it.
