Narrating over a Video using Multimodal AI

This n8n template takes a video and extracts frames from it which are used with a multimodal LLM to generate a script. The script is then passed to the same multimodal LLM to generate a voiceover clip. This template was inspired by Processing and narrating a video with GPT's visual capabilities and the TTS API How it works Video is downloaded using the HTTP node. Python code node is used to extract the frames using OpenCV. Loop node is used o batch the frames for the LLM to generate partial scripts. All partial scripts are combined to form the full script which is then sent to OpenAI to generate audio from it. The finished voiceover clip is uploaded to Google Drive. Sample the finished produ

Help me set up the n8n workflow "Narrating over a Video using Multimodal AI" (https://n8n.io/workflows/2467). It uses: Edit Image, HTTP Request, Google Drive, Code, Basic LLM Chain, OpenAI Chat Model, OpenAI. Import the template JSON into my n8n instance, list every credential I need to create, and walk me through testing it.
