Use case
Minecraft parkour text story video generator
Chat on top, parkour underneath. The gameplay occupies the part of a viewer's attention that would otherwise wander, which is why the format keeps people watching to the end.
Why split-screen holds attention
Reading alone leaves spare attention, and spare attention scrolls. Constant motion underneath absorbs it without competing with the story, because nothing in the gameplay needs to be followed.
Two parkour backgrounds
GifChat includes two Minecraft parkour clips plus Subway Surfers, and you can upload your own footage up to 30MB if you would rather use a clip nobody else has.
Keep the chat readable
The chat box sits in the top portion at a size that survives a phone screen. Short messages beat long ones: if a line wraps to three rows, it is a paragraph, not a text.
