guizang-ppt vs nanobanana-ppt: still HTML or animated video?

Both guizang-ppt and nanobanana-ppt are by @op7418. They share an aesthetic sensibility but target completely different production-value tiers.

guizang-ppt — the magazine

Magazine-style single-file HTML. WebGL fluid backgrounds for hero pages, 10 layouts, 5 themes, horizontal-swipe navigation. Free to run — no external API calls. Static-feeling but with subtle motion.

Best when:

Offline talk where you’ll be present.
Audience is design-aware.
Budget is zero.

nanobanana-ppt — broadcast quality

Generates 2K/4K imagery with Nano Banana Pro plus smooth inter-slide transitions with 可灵. Outputs both an interactive HTML5 player and a full MP4 video for distribution.

The cost: real money. Each deck costs ~$5-15 depending on slide count and resolution. So this is launch-grade, not weekly-update grade.

Best when:

Product launch deck where motion sells the idea.
Need a video deliverable for social distribution (LinkedIn, X, 视频号).
Budget allows.

30-second decision

Free / unlimited reruns?                → guizang-ppt
Audience is in the room?                → guizang-ppt
Need video file for distribution?       → nanobanana-ppt
Production value matters more than $$?  → nanobanana-ppt
Just need it now, no budget?            → guizang-ppt

You can use both for one event

For a product launch, common combo:

nanobanana-ppt for the social trailer (1-page MP4, distributed pre-event)
guizang-ppt for the actual on-stage presentation (interactive HTML, presenter controls)

Different tools for different surfaces of the same launch.
