Rendobar is a serverless media processing API that simplifies video and image workflows by executing FFmpeg commands in the cloud. It handles tasks like transcoding, trimming, concatenating, format conversion, scene detection, and metadata extraction. The platform creates videos from JSON timelines, generates AI-powered captions with multilingual translation, and burns subtitles from SRT or VTT files. It also produces styled QR codes. The API offers CPU and GPU compute options for scaling and integrates with AI agents via Model Context Protocol servers, available as a hosted service or npm package. A command-line interface supports job creation, progress tracking, and result retrieval. Rendobar manages workflows end-to-end, including input downloads, sandboxed job execution, and output delivery via webhooks or server-sent events. Inputs are deleted post-job, and outputs are temporarily stored before removal. It operates on a pay-per-job model with a free tier at signup.
