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.

Recommended upload bitrate by resolution
720p303,000–4,500 kbps
1080p304,500–6,000 kbps
1080p606,000–9,000 kbps
Too little bitrate for the resolution = a soft, blocky picture. Set the resolution and bitrate to match — and keep ~30% upload headroom so it stays stable.

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.

Frequently asked questions

Does Twitch allow simulcasting?

Yes, Twitch allows simulcasting, but you should still check the current terms and keep your local upload stable.

Can I stream to Twitch from OBS and YouTube at the same time?

Yes — send one feed to Stream Repeater and add both destinations there.
