"content": "## Generate SRT and VTT subtitle files from a media URL using Gladia and Google Drive\n\n### How it works\n\n1. Someone submits a public audio or video URL through the form.\n2. The workflow sends that URL to Gladia and asks for SRT and VTT subtitles.\n3. It waits and polls Gladia until the transcription is done, or stops after a set number of attempts.\n4. A Code node turns each subtitle track into a downloadable file.\n5. Both files upload to Google Drive and the form shows the two links.\n\n### Setup steps\n\n- [ ] Create a Header Auth credential named Gladia with header name x-gladia-key and your Gladia API key, then select it on Submit Media to Gladia and Fetch Transcription Result.\n- [ ] Connect your Google Drive account and set the destination folder on Upload Subtitles to Drive.\n- [ ] Adjust wait seconds and max attempts in Set Polling Config for longer media.\n\n### Customization\n\nChange the requested formats in Submit Media to Gladia, point the upload at a different Drive folder, or swap the form trigger for a webhook to run it from another system.",
