With an Imported PSD, there is not really a "scroll," per se.
However, to reveal material, that is effectively "cropped" by the Frame Size, you can adjust the Fixed Effect>Motion>Position.
I create a lot of Titles in PS, and use multiple Text Layers, as I often want to animate the Layers separately. I always create those on a New Image, that is the exact pixel x pixel dimensions, as my Project's Frame Size (sounds like about what you are doing), OR will create them, so that I can animate Motion>Position, to create a Roll. I also create the New Image with Guides for Title Safe Area. In the case of a Roll, I only use the width, and not the height, since I will animate to reveal the Text that is initially off-screen.
Check out Motion>Position, to see if you do have all of your Text, but are just not seeing it.
If you do not wish to do a Roll, redo the Titles, and keep all Text within the Title Safe Area.
Good luck, and let us know if that Text IS there, but just effectively cropped by the Frame Size.
Thanks Hunt. You stated that a bit better than I did.
I tried adjusting both the position and scale. Neither of those revealed the cropped letters so it seems as though what is being imported is limited to overall dimensions of the PSD and not necessarily the individual layer.
I can certainly redo the PSD. I was just hoping there was some workaround that I was missing since the original file was created by someone else and I don't want to run into the same problem in future. I'm still trying a few things so if I come up with anything that works I will post it here.
OK, I think that I see the problem.
If your Canvas, in Photoshop, is smaller than the Text Layer, that "extra" material (extra pixels) will be cropped when you Save the Image.
Go back to PS, and extend your Canvas (I would keep that enlarged Canvas to Transprent for the Background), to include those pixels.
When I am creating a Rolling Title in PS, my Canvas often ends up being, say 1920 x 4000 pixels, for long credit Rolls. Then, I use Motion>Position to animate that Text Layer (Import as a Sequence).
That did it. I guess I just wasn't thinking it through well enough.
Thanks for the help.
