What is Subtitle Video HD?
Subtitle Video HD is an advanced extension for Openclaw Skills designed to streamline the video production workflow. It allows developers and creators to upload HD videos and generate accurate subtitles using remote GPU nodes, eliminating the need for manual timing or expensive local hardware. This skill is optimized for high-speed rendering, providing finished 1080p MP4 files ready for YouTube and other social media platforms.
By leveraging sophisticated backend APIs, the skill handles complex tasks like aspect ratio adjustments, text overlays, and audio track management through simple natural language commands. It is a robust solution for anyone using Openclaw Skills who needs to produce polished, accessible video content without touching a single manual slider.
Subtitle Video HD Use Cases
- Adding subtitles in English to HD videos for YouTube or social media.
- Automating captioning for content creators who need to move fast.
- Generating 1080p video exports with hardcoded text overlays.
- Processing various video formats like MP4, MOV, and AVI without local codecs.
- Creating accessibility-compliant content with high-accuracy timing.
How Subtitle Video HD Works
- Securely connect to the backend API using a NEMO_TOKEN or an automatically generated anonymous token.
- Create a session to initialize the project and select the target language for subtitle generation.
- Upload video files up to 500MB via multipart upload or by providing a direct URL.
- Send natural language editing commands through a Server-Sent Events (SSE) pipeline to trigger AI processing.
- Poll the session state to monitor background processing and GPU rendering status in real-time.
- Export the final 1080p video and receive a high-speed download link for the rendered file.
