        "content": "# **Node Breakdown & Descriptions:**\n\n### \\* The workflow starts with a **Webhook** node named **“Accept Video Upload”**, which activates on an HTTP **POST** to `/mediaUpload`. It expects `multipart/form-data` with the file in the `media` field and defers responding until the last node, so the API reply can include the uploaded thumbnail’s metadata.\n\n### \\* The next node, **IF** named **“Validate Upload is Video”**, checks `{{$binary.media.mimeType}}` contains `video/`. Only true (video) items proceed. If it ever receives a non-video, the false branch can return a **400** (optional improvement).\n\n### \\* The **Write Binary File** node named **“Persist Upload to /tmp”** writes the incoming `media` binary to disk at `/tmp/<originalFilename or input.mp4>`. This produces a stable file path for FFmpeg to read from.\n\n### \\* The **Execute Command** node named **“Extract Thumbnail with FFmpeg (Auto-Install)”** runs FFmpeg to grab a single frame at **5 seconds**:\n\n* If FFmpeg exists in the environment, it uses it.\n* Otherwise it **downloads a static FFmpeg** build into `/tmp/ffmpeg` (no root needed) and uses that.\n* Command outputs `/tmp/thumbnail.jpg` (`-ss 5 -frames:v 1 -q:v 2`).\n\n### \\* The **Read Binary File** node named **“Load Thumbnail from Disk”** reads `/tmp/thumbnail.jpg` back into the item’s binary data, preparing it for upload (thumbnail is now available as the node’s binary output).\n\n### \\* The **Google Drive** node named **“Upload Thumbnail to Drive”** uploads the thumbnail image to your target folder (folder ID you configured). The file name is derived from the original video name with a `-thumb.jpg` suffix. On success, it returns Drive metadata such as `id` and `name`.\n\n### \\* Finally, the **Respond to Webhook** node named **“Return API Response”** sends a JSON response to the caller indicating success, including the Drive `thumbnailFileId` and `thumbnailName`, so the client can reference or share the thumbnail immediately."
