For a practical starting point, leave your base canvas at your monitor’s native resolution, set output to 1280×720 at 30 fps, and choose a bitrate your platform recommends and your upload connection can sustain steadily. Streamlabs Support recommends 720p30 for performance; it is a baseline, not a universal best. Test with the game or content you plan to stream, then adjust one setting at a time.
Start with a stable baseline
Streamlabs Desktop has separate controls for the production canvas and the video viewers receive. Keeping the base canvas native while lowering the output resolution can reduce encoding work without changing how you arrange your scenes. Streamlabs Support recommends a native-resolution base canvas and 1280×720 output, and describes 720p30 as its performance-oriented starting point in its July 9, 2026 getting-started guide.
| Setting | Starting point | What to consider |
|---|---|---|
| Base (canvas) resolution | Your monitor’s native resolution | This is the production canvas used to arrange sources and scenes. |
| Output (scaled) resolution | 1280×720 | This is the encoded resolution sent to the platform. Higher output means more encoding work; Streamlabs notes 1080p has twice as many pixels as 720p and can have a significant CPU impact. |
| Frame rate | 30 fps | A sensible performance-oriented choice and often sufficient for slower content. Try 60 fps for fast gameplay only if the computer and connection handle it. |
| Video bitrate | Use the destination’s guidance, within stable upload capacity | There is no bitrate that fits every platform, resolution, and connection. |
| Encoder | Hardware or software, according to observed capacity | The encoder uses the graphics card or processor to build the video. Test your system rather than assuming one is always better. |
In the current Streamlabs quick-start guide, base/output resolution and FPS are under Settings > Video; bitrate and encoder are under Settings > Output. Interface labels may change between releases, so look for the corresponding video and output controls if your version differs. See Streamlabs’ quick-start guide.
Choose bitrate for the platform, not a universal preset
Bitrate is the amount of video data sent each second. More resolution and frames generally need more bitrate, but setting it above what your internet connection can sustain can cause lag, buffering, or dropped frames. Leave stable upload headroom rather than treating a speed-test peak as guaranteed capacity.

Twitch-oriented examples from Streamlabs
Streamlabs’ July 2026 guide gives the following examples for Twitch using NVIDIA NVENC, CBR, a two-second keyframe interval, the Quality preset, and two B-frames. These are scoped examples, not universal settings or YouTube recommendations.
| Output | Frame rate | Streamlabs example video bitrate |
|---|---|---|
| 720p | 30 fps | 3,000 kbps |
| 720p | 60 fps | 4,500 kbps |
| 1080p | 30 fps | 4,500 kbps |
| 1080p | 60 fps | 6,000 kbps |
Streamlabs’ bitrate guidance likewise warns that insufficient upload capacity for a selected bitrate can cause lag, buffering, and dropped frames. Start at 720p30 if performance is uncertain, then raise resolution, FPS, or bitrate only after monitoring a representative test.
YouTube H.264 recommendations
YouTube’s current live encoder table gives different targets for H.264 ingestion: 8 Mbps at 720p30, 8 Mbps at 720p60, 14 Mbps at 1080p30, and 17 Mbps at 1080p60. These figures apply to YouTube’s H.264 column; its recommendations differ by codec, resolution, and frame rate. Do not substitute the H.264 figures for YouTube’s AV1 or H.265 guidance. Check the current YouTube live encoder settings for your intended codec and destination.

YouTube lists CBR, recommends a two-second keyframe frequency, and says not to exceed four seconds. It supports H.264, H.265, and AV1 ingestion. Streamlabs presets or examples for another platform may not match YouTube’s requirements, so check the destination’s current encoder guidance before going live.
Set the encoder and balance quality with game performance
Hardware encoding uses the GPU; software encoding uses the CPU. The better choice depends on the hardware and what the game or other applications are already using. A single-PC gaming stream can strain the same CPU and GPU needed for both rendering the game and encoding the stream. Streamlabs explains this competition in its game optimization guidance.
- If the game stutters or the encoder/rendering struggles, reduce output resolution or FPS first and retest.
- Cap the game’s frame rate at a level the system can sustain while streaming; lower demanding graphics settings if needed.
- Compare hardware and software encoders by testing under the actual game load, not while the computer is idle.
- Change one variable at a time so you can tell which adjustment helped.
Test the complete stream before going live
A clean local preview does not prove the upload is reaching viewers reliably. YouTube recommends a speed test, a test stream with representative audio and motion, and monitoring stream health. Its guidance says, “Make sure to test before you start your live stream.”

First distinguish network-related dropped frames from computer overload. They can look similar to viewers, but require different fixes.
Network instability or dropped frames during upload
- Check that upload performance is stable, not just fast in a brief test.
- Lower the bitrate if the connection cannot sustain it, then run another test.
- Streamlabs’ Dynamic Bitrate option can adjust bitrate when network conditions cause dropped frames. It helps with network variation; it does not fix an overloaded CPU or GPU.
Streamlabs describes Dynamic Bitrate and network-related troubleshooting in its getting-started guide.

Encoder/render lag or a stuttering game
- Reduce the output resolution or FPS to lower the encoding load.
- Cap the in-game frame rate and reduce demanding game graphics settings if the game is consuming the resources the encoder needs.
- Test again with the game running; a setting that works on an idle desktop may fail under gameplay load.
These symptoms point toward resource competition rather than a bitrate-only problem; Streamlabs discusses the interaction of game and encoding load in its game optimization guide.
Viewers report buffering, but the preview looks fine
Lower output resolution or bitrate and check the platform’s stream-health information. The local preview may look sharp even when viewers cannot receive the stream steadily. On platforms that offer transcoded quality options, viewer access to those options may also affect how people on slower connections experience the stream. Raising bitrate simply because the preview looks soft can make buffering worse.
Audio or capture is missing
Confirm the intended microphone and desktop audio devices are selected, and check that their mixer meters move when sound is present. Verify that the correct capture source is visible in the active scene. Make a private or unlisted test where possible so you can catch audio or capture problems before a public broadcast.
