Who is this for
Content creators, YouTubers, and social media managers who want to repurpose long form videos into short clips without doing it manually. Works on self hosted n8n instances.
What it does
Monitors a Google Drive folder for new videos. When a video appears, the workflow downloads it, extracts the audio, transcribes it using Whisper, and sends the transcript to OpenAI to identify the best highlight moments. Each selected clip is then rendered in three aspect ratios (9:16 for TikTok, 9:16 for Reels, 1:1 for Square) using cloud based FFmpeg through RenderIO. The finished clips are uploaded back to Google Drive and every run is logged to a Google Sheet.
How it works
1. Watch Drive Folder polls your source folder every minute and triggers when a new video file is detected. 2. Set Config holds all tunable settings in one place: clip count, folder IDs, sheet IDs, and LLM model. 3. The video is downloaded from Google Drive and uploaded to RenderIO for processing. 4. Extract Audio runs an FFmpeg command to pull the audio track from the video. 5. The audio is sent to Whisper for transcription. Both TXT and SRT transcript files are saved to Google Drive. 6. Pick Clips sends the transcript to OpenAI, which returns timestamped highlight suggestions. 7. Validate Clips checks that all timestamps and durations are valid before rendering. 8. Each clip is rendered in three formats through [RenderIO](https://renderio.dev) with separate FFmpeg commands for each aspect ratio. 9. All rendered clips are downloaded and uploaded to a dedicated output folder in Google Drive. 10. Append Clip Row logs each clip to a Google Sheet and Append Run Summary records the overall processing stats.
