I don't believe there's a way to do this with the DVE transition.

Here's two options that you could go for:

1. If you're happy with the Lower Third simply fading in, chuck it in a Media Player and set the Downstream Key 1 to the repsective Media Player and Media Player Key. You can change the rate that the DSK comes in, then hit On Air in the DSK controls when you want the lower third to fade in.

2. If you want the Lower Third to "push in" then "push out" for example, you will have to set it up in Photoshop as an Animation. Animations are really quick n easy to setup in PS with keyframes. Once set up as you wish, export it as a TGA sequence and then import the TGAs into a Clip Pool on the ATEM 1 M/E. A pool can have a maximum of 180 frames, which should be sufficient for quick lower thirds. 0.5 seconds for the push in, 5 seconds on display, then 0.5 seconds for the push out (slightly more if you're working in 50i @ 25fps). It is important that the first and last frames are black/null.

Now, set the DSK to Fill Media Player 1 and Key as Media Player 1 Key and in the DSK controls, set it to On Air. Since the first frame of the sequence is empty, nothing will be dispalyed.

Now that you've "primed" the lower third, simply hit the Play button on the Media Player control when you want the sequence to appear On Air. It will appear exactly as you set the animation in Photoshop.
