# Video Recording for E-Learning (URZ)

This source provides guidance from the Universitätsrechenzentrum (URZ) on creating video recordings of screen presentations and camera feeds for educational purposes at the Universität Greifswald.

## Core Recommendations
The URZ distinguishes between two primary recording paths based on the complexity of the desired output:
- **Simple Recordings**: For recordings consisting solely of a camera feed or a screen presentation, [[opencast-studio]] is recommended.
- **Complex Recordings**: For videos requiring simultaneous camera and screen views, custom layouts, or effects, [[obs-studio]] is recommended.

## Technical Requirements
Regardless of the software chosen, the URZ specifies the following prerequisites:
- Modern, high-performance hardware.
- Input devices including a camera, microphone, and/or headset.

## Tool-Specific Workflows

### Opencast Studio
- **Access**: Available via the shortlink `rz.uni-greifswald.de/record`.
- **Nature**: Browser-based and runs locally; no data is sent to a server during recording.
- **Post-processing**: Files produced (MP4/WEBM) often lack essential runtime information and may have resolution issues. These must be corrected using [[ffmpeg]] before they can be processed by [[grypstube]].
- **Correction Method**: The URZ provides a ZIP archive containing a BAT file and FFmpeg for Windows users to automate this correction via drag-and-drop. Corrected files are saved with the `_opt` extension.

### OBS Studio
- **Capabilities**: Allows arranging multiple video sources into a single output file with custom layouts.
- **Laptop GPU Conflict**: On Windows laptops with dual GPUs (e.g., Intel and NVIDIA/AMD), OBS may fail to capture windows if it runs on the high-performance GPU while the target application runs on the energy-saving GPU.
- **Solution**: Set OBS Studio to "Energy Saving Mode" (Energiesparmodus) in the Windows Graphics Settings to ensure it uses the same GPU as the operating system and standard applications.

## Support
Technical issues are handled by the [[universitatsrechenzentrum-urz]] via the [[groupware]] ticket system or the hotline (ext. 1420).
