Method 1

Stream Key – Most Common & Reliable 🔑

This is the traditional way to connect OBS to YouTube Live. You copy a unique stream key from YouTube and paste it into OBS. It works every time and is perfect if you prefer manual control.

1. Go to YouTube Studio → click Create → Go Live.
2. Fill in your stream details (title, description, thumbnail, privacy).
3. In the Stream Settings tab, copy the Stream Key (and note the Stream URL – usually rtmp://a.rtmp.youtube.com/live2).
4. In OBS, go to Settings → Stream → choose Service: YouTube - RTMP → paste the Stream Key.
5. Click “Start Streaming” in OBS, then return to YouTube and click “Go Live” once OBS shows it’s connected.

Keep Your Stream Key Secret
Never share your stream key publicly. If someone obtains it, they can broadcast to your channel without your permission.

Method 2

Connect YouTube Account Directly in OBS 🔐

If you manage multiple YouTube channels, this method is a game‑changer. OBS will automatically fetch your stream key and even let you switch between brand accounts without re‑entering any keys.

1. In OBS, go to Settings → Stream → select Service: YouTube - RTMP.
2. Click the “Connect Account (recommended)” button and sign in with your Google account.
3. Grant the necessary permissions. OBS will now automatically fill in your stream key – no copy‑pasting needed.
4. You can also set the stream title, privacy, and other options directly from OBS before going live.

Perfect for Two Channels Once connected, you can click your channel name in OBS to switch between your YouTube accounts (or brand channels). No more hunting for different stream keys.

Method 3

One‑Click Auto‑Start Streams (OBS 28+) ⚡

With a connected YouTube account, you can enable auto‑start. The moment you hit “Start Streaming” in OBS, the stream goes live on YouTube automatically – no extra clicks in YouTube Studio required.

1. Make sure your YouTube account is already linked using Method 2.
2. In the same Stream settings, check the option “Enable auto‑start” (or similar wording, depending on OBS version).
3. Now, whenever you click “Start Streaming” in OBS, YouTube will create the live event and go live immediately using the default settings you’ve configured.

This is ideal for scheduled streams where you’ve already set up titles and thumbnails in advance.

Time Saver If you stream regularly at the same time, auto‑start eliminates the step of manually clicking “Go Live” on YouTube. Just press one button and you’re on air.

Method 4

Custom RTMP with Third‑Party Tools (Restream, etc.) 🔄

If you want to broadcast to YouTube and other platforms (Twitch, Facebook, LinkedIn) at the same time, a middle‑layer service like Restream.io is the way to go. You send one stream to Restream, and it redistributes to all your destinations.

1. Sign up for a free account at Restream.io (or a similar service).
2. Add your YouTube channel as a destination in Restream’s dashboard – it will guide you through linking it.
3. Copy the RTMP server and stream key that Restream provides (not YouTube’s).
4. In OBS → Settings → Stream → choose Custom… and paste the Restream server/key.
5. Start streaming in OBS. Restream will push the feed to YouTube (and any other connected platforms) simultaneously.

Note The free Restream plan adds a small watermark to your non‑Restream channels. For professional multi‑streaming, a paid plan is recommended.

Quick Quality Settings for YouTube Live 🎛️

For a smooth, high‑quality stream that meets YouTube’s requirements, use these recommended settings:

• Output Resolution: 1080p (1920x1080) at 60 fps
• Bitrate: 6000 – 9000 Kbps for 1080p60 (if your internet can handle it)
• Encoder: Use NVIDIA NVENC if you have an Nvidia GPU, otherwise x264
• Keyframe Interval: Set to 2 seconds (YouTube’s requirement)
• Audio: AAC codec, 128–160 Kbps

You can find these options under Settings → Output (enable “Advanced” mode) and Settings → Video.

Pro Tip If you experience dropped frames, lower the bitrate by 500–1000 Kbps at a time. A stable stream is better than a high‑quality stream that keeps buffering.
