Create an animation video that explains how Retrieval-Augmented Generation works. A user query gets embedded into a vector. That vector searches a vector database to retrieve similar text chunks. If no relevant chunks are found above a confidence threshold, show the system returning a "no relevant context found" message. If relevant chunks are found, those chunks are combined with the original query into a prompt. That prompt is sent to an LLM which generates a response. The LLM response is shown to the user. Additionally, show a feedback loop where the user can rate the response as helpful or unhelpful — if unhelpful, the system re-runs the vector search with a modified query to try retrieving different chunks, then sends the new chunks to the LLM for a second attempt. Label each component clearly — user query, embedding, vector database, confidence threshold, retrieved chunks, prompt assembly, LLM, response, feedback, and query refinement. Show how data flows between each component, including the retry loop when initial retrieval fails.

Create an animation video that explains how cloud storage services like Google Drive or Dropbox work. Show a title card with the text "How Cloud Storage Works" at the start. Explain the following steps: when a user saves a file, it gets broken into chunks and encrypted. Those encrypted chunks are distributed across multiple servers in different geographic locations for redundancy. When the user accesses the file from another device, the app detects which chunks are already on that device and only downloads the new or modified ones. Show what happens when the same file is edited on two different devices at the same time — both devices make conflicting edits and save them. The system detects the conflict, preserves both versions, and lets the user choose which one to keep. Label each component clearly — user device 1, user device 2, file chunks, encryption, chunk servers (distributed), sync service, conflict detection, version history. Show how data flows between devices and servers, and how the system handles the sync and conflict scenarios.
