Settings for Twitch, YouTube and Kick
| Platform | Encoder (Settings → Output) | Resolution | Bitrate (CBR) |
|---|---|---|---|
| Twitch | AMD HW H.264 (AVC) | 1080p60 (900p60 for fast shooters) | 6,000 kbps |
| YouTube | AMD HW AV1 | 1440p60 | about 17,000 kbps |
| Kick | AMD HW H.264 (AVC) | 1080p60 | 8,000 kbps |
- Twitch: Turn on Enhanced Broadcasting (Settings → Stream) if Twitch offers it to you; it then picks the codec and bitrate itself.
- YouTube: YouTube gets its better VP9 playback at 1440p; at 1080p60 use about 8,500 kbps.
- Kick: Kick takes H.264 only, with CBR.
Use rate control CBR, keyframe interval 2 s and 160 kbps audio on every platform. These bitrates assume a steady upload of at least 10 Mbps (about 22 Mbps for 1440p on YouTube); the finder sizes them to your real connection.
Encoder preset

| Preset | Quality |
| Profile | high |
If the game stutters while streaming, choose the Balanced preset before lowering the bitrate.
Why these settings for the RX 9070 XT
Encoder hardware: RDNA 4 media engine. Codecs: H.264, HEVC, AV1.
AMD reworked the encoder for RDNA 4: about 25% better low-latency H.264 quality and 11% better HEVC than RDNA 3, and AV1 gains B-frames. That closes much of the gap with NVIDIA for streaming.
The RX 9070 XT has a dual media engine, so it can stream and record at the same time without the two competing.
Codecs by platform: Kick takes H.264 only. Twitch's standard ingest is H.264; Enhanced Broadcasting can send HEVC or AV1 where Twitch allows it. YouTube accepts H.264, HEVC and AV1 (OBS 29.1 or newer).
What about the CPU encoder (x264)?
Even on a fast gaming CPU such as the Ryzen 7 9800X3D, the GPU encoder is the better default: it barely touches game performance, while x264 takes CPU time from the game. Use x264 only if your card has no encoder, or on a second streaming PC; start at preset veryfast and move to faster only if OBS shows no encoding lag.
