Is it possible for the xmp files to embed visible text into the image file (like a watermark).

I am interested in including select EXIF info in the image series so it is included as text in the image itself. I'd like the ability to show exposure info, frame #, ISO, date shot and so on, all for use in distributed dailies.

I am currently trying Watermark Factory, but it is very slow, and is an added step.

Is this something LRTL can include or execute upon returning to LR and be visible in the exported files?

Hi Betha, you could use the text feature in the Lightroom Slideshow module. Since that module is beeing used to export the movies, why not use it. Start with the slideshow templates I provide and add your text to them in the slideshow module. You can use different fields at different positions. It's entirely a lightroom-slideshow thing!
Only make sure you don't edit the framerate (secs/image).
