Automated Video Captioning with json2video Integration

This n8n workflow automates the process of adding captions to a video using the json2video API. Starting from a manual trigger, it prepares video parameters such as URL and dimensions, then sends a POST request to the json2video API to generate a video with subtitles. The workflow includes a delay to allow processing time, followed by regular status checks to monitor the progress. If an error occurs, it gracefully handles the situation; otherwise, it outputs the finalized video information, including URL, size, and rendering details. This automation is especially useful for content creators and marketers aiming to efficiently generate captioned videos without manual intervention, streamlining the post-production process.
