How do I restream to Twitch?
If Twitch is one of your destinations, the cleanest setup is to send one feed into a relay and let it push the stream to Twitch from the cloud. That avoids the upload spikes and dropped frames that come from trying to hit Twitch and other platforms directly from your PC.
Use one encoder output
Whether you use OBS, vMix, Streamlabs or FFmpeg, configure a single custom RTMP output to Stream Repeater. The relay then handles Twitch plus any other destinations you want live at the same time.
Keep Twitch-friendly settings
Twitch is happiest with a 2-second keyframe interval and a bitrate your upload can sustain comfortably. If you plan to stream to multiple platforms, size the source for the relay once rather than duplicating the job locally.
Add Twitch in the dashboard
Create or paste your Twitch stream key into the destination settings in Stream Repeater, then let the relay supervise the connection. If Twitch hiccups, the relay can restart that destination without you touching the encoder.
