There are a couple of ways to do this.
Option 1: Vector Motion
- Reset the text's position.
- Deselect the text layer in the Properties panel, then adjust the position in the Properties panel. This adjusts the Vector Motion settings, which control the overall position of the graphic.
- Copy the clip in the timeline.
- Select the other graphics in the timeline and choose Edit > Paste Attributes and make sure Vector Motion is ticked.
Option 2: Transform effect
- Reset the text's position.
- Apply the Transform effect and adjust the position with this effect instead.
- Copy the clip.
- Select the other graphics in the timeline and choose Edit > Paste Attributes and make sure Transform is ticked.
Note: The advantage of using Vector Motion is that it always overwrites the previous setting. If you need to update the position repeatedly, pasting Transform keeps adding new instances of the effect.
Another option is to start with captions instead of graphics. Captions let you select more than one in the timeline and adjust their positions all at once. If you need them as graphics afterward, choose Graphics and Titles > Upgrade to Source Graphic.
