Recording Clips Locally
Capturing clips is on the Glimesh.tv roadmap but is not yet supported. However you can still capture clips locally using OBS Studio for later uploading to YouTube or another service. A benefit of this is that local clips can be configured to be much higher quality than your stream.
These instructions are based on the following Nvidia NVENC guide but can be adapted to other encoders: https://www.nvidia.com/en-us/geforce/guides/broadcasting-guide/
First, set up your recording settings using the advanced output mode.
Second, enable Replay Buffer and optionally set a Hotkey to save the buffer and optionally check the setting under General to automatically start the buffer when you start streaming.
