A small animated arrow that lands beside the button you are explaining can be more useful than an elaborate full-screen transition. It directs attention and gets out of the way.
Adobe's August 18 documentation describes a Firefly workflow for generating foreground video with transparency. The download contains separate foreground and alpha videos, which you combine in an editor. That detail matters: this is not a promise that every downloaded file will behave like a ready-to-use transparent clip when dragged into any timeline. Firefly transparent-video guide
Here is a proposed workflow for building a small overlay library for tutorials and product demonstrations.
Give every overlay one job
Start with three assets: an attention marker, a section transition, and a completion accent. Write a sentence describing when each appears.
An attention marker should point to a detail without covering it. A section transition should signal a change without forcing a long pause. A completion accent should finish quickly enough that repeated use does not become irritating.
Avoid designing the whole visual identity at once. Finish one asset in a real edit, then use what you learned to guide the others.
For the attention marker, a useful request might describe a simple curved arrow drawing into place, with a clean silhouette, restrained motion, and an ending that holds briefly. Keep exact interface labels and instructions as ordinary editor text so you can revise them accurately.
Plan the composition around the footage
Pick a frame from the actual tutorial and decide where the overlay can sit. Leave space for captions, the cursor, and the object being explained.
Create a rough layout before generating. A scribbled rectangle marking the safe area can prevent repeated attempts that place the graphic in the wrong part of the frame.
Firefly's transparent-background mode supports transparent PNGs as optional first and last frames; some other settings become unavailable in that mode. Follow the current interface for supported combinations. Adobe's transparency requirements
If the graphic must match an existing brand asset, use an approved reference rather than asking the model to reconstruct a logo from memory. Precise text and logos deserve a direct comparison with the originals.
