Ticker was designed for semiautonomous lower thirds information, but has potential for other things. In our case, as a worship facility, it has obvious possibility in two areas:
1. Word for songs the congregation is singing
2. Scripture passages being read aloud.

We presently use Titles for the songs, creating a three line lower thirds box that is populated from a CSV file. Each entry in quotes is a title, and we can advance forward (or backwards if needed) through them. Often only one or two of the lines is used for a given entry. But scrolling would be smoother.

We just started using the ticker for scripture. The entire passage is in a pair of quotes and scrolls through. But getting into and out of it is challenging. The mode has to be set to REPEAT to get started. We then generally let it scroll up three or four lines offline so they will hit at once. Then change the mode to ADD. When we "take" it, it starts scrolling (we use 0.8 speed), and it can be paused either from the input or a shortcut.

There are several enhancements to the ticker that could make it more useful, some fairly easy, others more involved:
1. Add a third mode that starts from the beginning, with possibly an optional offset so it could start with several lines showing, but doesn't repeat. Maybe call it PRESENTATION. Maybe it could just be a mix of REPEAT and ADD such that if triggered when at the end it starts over, but if triggered in the middle it continues from where it was.
2. There is a shortcut for speed, but for this application, access via a joystick or pot or similar analog input would be helpful. At present we can allocate two or three buttons (on our StreamDeck) to different speeds, including 0, but that is awkward. Even a pair of shortcuts (speed up and slow down) with incremental constants would improve it for this application.
3. Make speed allow reverse as well (i.e. negative numbers or below some midpoint threshold, or different direction on joystick). Sometimes one needs to go backwards. And they may need to go backwards fairly rapidly, such as repeating a section of a song.
4. This is probably the most complex part, but it would be useful to have a combo of ticker and title. Title works fairly well for songs where word wrap should be manually controlled by design. Ticker works better for scriptures where word wrap should be done during rendering. But it would be nice to be able to scroll in title. I haven't played with ticker too much. Maybe it can scroll through consecutive entries or have RETURN characters breaking it into lines. Without the ability to reverse, it is of limited value in this application.
Maybe it needs the ability to smooth scroll or advance (forward or backward) one item at a time, each item being the CSV contents between quote marks.
5. Speaking of CSV and quote marks, is there a way to change the default delimiter (like Excel can do)? Unfortunately, we often encounter text (both songs and scripture) that include portions in quotation. Our present approach is to replace them with single quotes, but that is not ideal. I'd rather assign some other character, such as @ as the delimiter instead (or even left and right curly braces or brackets, although that would fundamentally change the code, because it would be separate start and end symbols.)

We really appreciate vMix, and the ability to use overlays on mix inputs is a very welcome addition. vMix, is just about the only program out there that can manage multiple outputs (iso outputs from Mix inputs). We have four outputs (two of which are identical most of the time). We use short cuts with a Stream Deck to keep them all in sync. (They generally change at the same time, but not to the same material. Our local audience doesn't need to have the stage on camera, or see audience shots, but both local and remote audiences need overlays (although sometimes differently). Also PPT needs to be handled differently for local and remote audiences.)

Another thing I appreciate is the respect vMix shows for customers. The 60 day trial and reasonable upgrade costs. I explored a competing program that added so much annoying stuff in evaluation mode that it was hard to see what it was actually doing, and impossible to actually try it in a service. The fact that vMix allows a second copy is also invaluable, as I prepare material at home and then transport it to church on a flash drive.
