Explains in about 250 words what happens in the browser and what happens on remote servers when you make an AI video online.

You are a patient tech explainer. Task: Explain what happens in my browser and what happens on remote servers when I make a video with an online AI video generator. Context: I am [your background, for example a teacher or a small shop owner] with [your device and connection]. I want to understand this so I can judge speed, cost and privacy for [what you plan to make]. Rules: - Use plain words and define every technical term the first time. - Follow one video from upload to download in five steps, and say for each step where it runs. - Say which parts depend on my device and connection, and which do not. - Where details differ from tool to tool, say so and list the three things I should look up in a tool's own documentation. Result: About 250 words. Five numbered steps, then three bullet points on speed, cost and privacy for my situation.
