Overview
This node operation allows users to add captions to a video by processing a video file from a provided URL. It supports various caption input formats including raw text, SRT, and ASS files, or can auto-transcribe if no captions are provided. Users can customize caption appearance and behavior with settings such as alignment, font style, color, position, and caption style (e.g., classic, karaoke). It also supports text replacements, exclusion of specific time ranges from captions, and webhook notifications upon completion. This is useful for enhancing video accessibility, creating subtitles for different languages, or adding stylized captions for presentations or social media content.
Use Case Examples
- Adding subtitles to a training video by providing an SRT file URL.
- Auto-transcribing and captioning a video in a specific language for accessibility.
- Customizing caption style and appearance for a marketing video to match brand guidelines.

Troubleshooting
- Ensure the video URL is accessible and correctly formatted to avoid processing errors.
- If captions are provided as URLs, verify that the URLs are reachable and the files are in supported formats (SRT or ASS).
- Check language codes for correctness; use 'auto' for automatic detection if unsure.
- If webhook notifications are not received, verify the webhook URL is correct and publicly accessible.
- Timeout errors may occur if the server is slow; adjust the timeout setting accordingly.
- SSL certificate errors can be bypassed by enabling the 'Ignore SSL Issues' option, but use with caution.
