# Opencast Studio

**Opencast Studio** is a browser-based video recording application recommended by the [[universitatsrechenzentrum-urz]] (URZ) for creating educational content and simple e-learning video captures. Because it operates within the browser, it provides a low-barrier entry for instructors to record lectures or demonstrations without installing complex local software.

It is part of the recommended recording toolset for [[digital-teaching]] at the Universität Greifswald.

## Key Features
- **Accessibility**: Accessed via the university shortlink `rz.uni-greifswald.de/record`.
- **Privacy**: The application runs entirely locally within the web browser; no recording data is transmitted to a server during the process.
- **Capabilities**: Supports recording of the screen, webcam, or both simultaneously, along with audio.
- **Output**: Users must manually download and save the resulting video files to their local device.

## Technical Limitations and Workflow
While described as the simplest recording method, Opencast Studio files (MP4 and WEBM) are often not ready for immediate processing by the [[grypstube]] server due to missing runtime information and resolution inconsistencies.

To resolve this, the URZ mandates a post-processing step using [[ffmpeg]]. This is typically achieved via a provided BAT file for Windows users, which generates a corrected version of the file with the `_opt` extension.
