How do I determine the best OBS bitrate and resolution for 1080p 60fps streaming?

For 1080p 60fps, Twitch recommends up to 6,000 kbps, Kick allows around 8,000 kbps, and YouTube Live supports 9–12 Mbps. Use CBR rate control, a 2-second keyframe interval, and keep your total bitrate under 75% of your stable wired upload speed. The Streamer Companion bitrate calculator applies these platform caps automatically from your resolution and upload speed.

How do I configure stream audio sample rates and bitrates for clean broadcast audio?

Set a 48 kHz sample rate, the broadcast standard, and an audio bitrate of 160–320 kbps depending on your platform cap — Twitch allows 160 kbps and YouTube Live up to 320 kbps. Higher sample rates add no benefit and can cause audio sync drift, while too-low bitrate makes your mic sound compressed. Match the audio bitrate to your platform cap and prioritize clean mic processing over raw bitrate.

How do bandwidth and upload speeds impact stream stability and frame drops?

Dropped frames almost always mean your bitrate exceeds what your connection can sustain. Add your video and audio bitrates for total throughput, keep it under 75% of your wired upload speed, use CBR with a 2-second keyframe interval, and pick the ingest server with the lowest ping. A wired Ethernet connection is essential — Wi-Fi causes fluctuating throughput and dropped frames. Persistent drops below 1% are normal; anything higher needs attention.

How do I set up stream companion overlays and alert widgets for live streaming?

Add overlay widgets as Browser Sources in OBS Studio or Streamlabs — paste the widget URL, set the resolution to 1920x1080, and replace the default Custom CSS body background with body { background: transparent !important; } so the widget composites transparently. For Streamer Companion prompt cards, toggle OBS Overlay Mode on first, position and resize alerts on your canvas, and uncheck Shutdown source when not visible so widgets persist between scene switches.

What are the best practices for multi-platform streaming to Twitch, YouTube, and Kick?

Each destination consumes its own bandwidth unless you use a restreaming service like Restream or Castr, which takes one feed and redistributes it. Always test on a wired Ethernet connection, tailor your bitrate to each platform's cap (Twitch 6 Mbps, Kick 8 Mbps, YouTube 9–12 Mbps), use a 2-second keyframe interval, and use a hardware encoder like NVIDIA NVENC to offload encoding. Streamer Companion's tools and overlays work across all three platforms from a single browser source.

Live Streaming Terms Glossary: Bitrate, Encoders, and OBS Settings Explained

A plain-English reference for the terms you will see in OBS Studio, Streamlabs, and your streaming platform's settings. Use it alongside the OBS Setup Guide and the bitrate calculator on the home page.

Bitrate: The amount of data your stream sends per second, measured in kilobits per second (kbps). Higher bitrate means better image quality but requires more upload bandwidth. Video and audio bitrate are set separately in OBS output settings.
CBR (Constant Bitrate): A rate control mode that keeps the bitrate steady regardless of how complex the scene is. Most platforms recommend CBR for live streaming because it produces a smooth, predictable feed that transcoders handle cleanly.
VBR (Variable Bitrate): A rate control mode that raises and lowers the bitrate based on scene complexity. More efficient for recordings, but can cause buffering on live streams when spikes exceed your upload ceiling.
Encoder: The hardware or software that compresses your raw video into a streamable format. Common encoders are NVENC (NVIDIA GPUs), AMF (AMD GPUs), QuickSync (Intel), and x264 (CPU software encoding).
NVENC: NVIDIA's hardware encoder. The recommended choice for most single-PC streamers because it offloads encoding from the CPU, leaving headroom for gameplay. Modern NVENC (Turing and newer) rivals mid-range x264 presets in quality.
x264: A software (CPU-based) encoder. Offers excellent quality at high presets but competes with your game for CPU cycles. Best for dual-PC setups where a dedicated streaming PC handles encoding.
Keyframe Interval (GOP): How often a full frame is sent, in seconds. Most platforms want a keyframe every 2 seconds for smooth transcoding. Set this to 2s in OBS output settings unless your platform specifies otherwise.
Ingest Server: The server your stream is sent to before it reaches viewers. Choosing the ingest server closest to you (by ping, not just geography) reduces dropped frames and latency. Twitch lists ingest servers by region.
Transcoding: When a platform re-encodes your stream into multiple resolutions (1080p, 720p, 480p) so viewers on slower connections can watch. Twitch offers transcoding based on availability; YouTube transcodes most streams automatically.
Dropped Frames: Frames your encoder produced but could not send, usually because your connection to the ingest server is saturated. Persistent dropped frames mean your bitrate exceeds your stable upload speed — lower it or switch to a closer ingest server.
Resolution: The pixel dimensions of your stream, such as 1920x1080 (1080p) or 1280x720 (720p). Match your canvas and output resolution in OBS, and scale down rather than up if your hardware or bandwidth is limited.
FPS (Frames Per Second): How many frames your stream sends each second. 30fps is smooth for most content; 60fps is preferred for fast-paced games but doubles the encoding load. Only target 60fps if your hardware and bandwidth can sustain it.
Rate Control: The method the encoder uses to decide how many bits to spend on each frame. CBR, VBR, and CQP are the common options; CBR is the safe default for live streaming.
Audio Bitrate: The data rate of your stream's audio track, typically 128–160 kbps for stereo speech and music. Keep audio bitrate well below your video bitrate, and never let the combined total exceed your upload budget.
Sample Rate: How many audio samples per second your microphone captures, usually 44.1 kHz or 48 kHz. Match your mic, OBS, and output sample rate to avoid drift and artifacts.
Browser Source: An OBS source type that renders a web page inside your scene. Used for overlays, alerts, and interactive prompt cards. Set a transparent body background so the page composites cleanly over your gameplay.
Latency: The delay between an event happening on stream and the viewer seeing it. Lower latency improves chat interaction but can increase buffering; most platforms offer a low-latency mode you can toggle per stream.
Subathon: A marathon stream where each subscription, donation, or bit adds time to the clock. Interactive prompts and viewer-submitted challenges are a staple of subathons because they keep the energy high across long sessions.
