Change dashboard column without jump
I'm not sure if this can be done, but here goes:
I have this clip of clouds moving across a sky. It's about 5 minutes long and loops continuously throughout a 15 minute scene. I also have a clip of birds flying across the sky. It's about 5 seconds long and doesn't loop. The birds enter from screen left and fly across the frame, exiting screen right. I want to cue the birds on a particular line of dialogue in the scene so that it looks like they're flying over the clouds. So I want the birds to come in, but without breaking the motion of the clouds. What's the best way to set that up in the dashboard?
