Neither is a universal quality winner. The right choice depends on the encoder generation, codec, bitrate, content, and whether your system can keep the stream stable.
What hardware and software encoding mean
Encoding turns your video into a stream format YouTube can ingest. The labels describe where that work happens, not the codec itself. In OBS, x264 is a software encoder that uses the CPU. A hardware encoder uses a specialized component, often in a GPU, to do the encoding. OBS explains the distinction in its hardware encoding guide.

H.264, H.265/HEVC, and AV1 are codecs: they describe how video is compressed. A device and application may offer some codecs in software, some through hardware, or both. Check the actual options exposed by your encoder rather than assuming that every GPU or CPU supports the same combination.

Should you use NVENC or x264 for YouTube streaming?
| Factor | Hardware encoding (such as NVENC, where supported) | Software encoding (such as x264) |
|---|---|---|
| Where encoding runs | A dedicated hardware component, often within a GPU | The CPU |
| Potential system benefit | Can preserve CPU capacity for a game or production workload | Uses CPU capacity that may also be needed by the game or production workload |
| Quality at the same bitrate | Depends on encoder generation and settings; older generations can produce lower quality than x264 at its default “veryfast” preset | Depends on CPU, preset, codec, and settings; it is not automatically better in every comparison |
| Codec availability | Varies by device generation and application; verify the actual options | Varies by encoder and application; verify the actual options |
| Best decision test | Choose it if your supported hardware encoder lets your system sustain the target stream more reliably | Choose it if the CPU can sustain the target settings and you prefer its available preset behavior |
OBS says, “Modern hardware encoders provide very good quality video with minimal performance impact.” That is general guidance, not a guarantee about every device or a benchmark proving one encoder always wins. OBS also notes that earlier hardware encoders can deliver lower quality at the same bitrate than software encoding with the default “veryfast” preset. Generation and settings matter.

NVIDIA describes NVENC as dedicated hardware in GeForce RTX GPUs. Its OBS options include H.264 and HEVC, and AV1 on RTX 40-series GPUs; those are NVIDIA product-guide details, not a claim covering every GPU or software setup. Check NVIDIA’s current broadcasting guide and your device’s specifications before relying on a particular model or codec.
Choose based on the workload you need to sustain
Favor hardware encoding when CPU headroom is tight
If a game, browser sources, capture, or production tools already keep the CPU busy, a supported hardware encoder can move encoding work off the CPU. This can make it easier to sustain your chosen resolution and frame rate, but it does not guarantee a stable stream: the encoder still has to support your settings, and the whole system and upload connection must hold up.

Use software encoding when your CPU has room
x264 remains a viable option when the CPU can handle both the stream and other work without dropped frames or overload. It can also suit creators who prefer its preset behavior. Compare the resulting picture at your intended bitrate and representative content rather than assuming software encoding is inherently better.
Do not buy hardware without a real need
YouTube supports software encoder applications as well as hardware encoders; its encoder setup guide says expensive equipment is not required to get started. Consider a graphics card with hardware video encoding only if your existing equipment lacks a compatible encoder or cannot reliably sustain the workload you need. The sources do not establish a best model or a reason every streamer should upgrade.

Match the encoder settings to YouTube’s ingest guidance
YouTube’s current live encoder guidance covers RTMP/RTMPS ingest, H.264, H.265/HEVC, and AV1, frame rates up to 60 fps, constant bitrate (CBR), and a recommended two-second keyframe interval that should not exceed four seconds. YouTube recommends RTMPS. It transcodes live streams for playback across viewer devices and network conditions. These are platform ingest recommendations, not evidence that one encoding location is preferred. See YouTube’s encoder settings, bitrates, and resolutions.
The following selected recommended bitrates come from YouTube Help’s guidance accessed in 2026. They are recommendations, not guaranteed optimal settings for every scene or connection; YouTube also publishes minimum values and other resolution and frame-rate combinations.

Choose a target your upload connection can reliably carry, and confirm YouTube’s current table before configuring a stream because recommendations can change. A higher setting is not automatically better if the encoder or connection cannot sustain it.
Test before the broadcast
- Confirm the available encoder and codec. In your streaming application, identify whether the selected option is software or hardware, and check that the device supports the codec and output settings you intend to use.
- Set YouTube-compatible output. Use CBR, set a two-second keyframe interval (never over four seconds), choose a supported codec and frame rate, and match the bitrate to YouTube’s current recommendation and your reliable upload capacity.
- Run a representative test. Include the movement, scene complexity, overlays, and audio that resemble the real broadcast. YouTube says, “Make sure to test before you start your live stream.”
- Inspect the Live Control Room preview and stream health. Watch for warnings, dropped frames, or audio and video problems while the test is running. YouTube’s live encoder settings guidance and stream health guidance explain the platform-side checks.
- Change one variable at a time. If the stream is unstable, test a lower resolution, frame rate, or bitrate, or switch encoder type if a compatible alternative is available. Repeat the test with the revised settings before relying on them live.
HDR is a codec-specific exception
YouTube’s HDR live workflow currently requires H.265/HEVC. Its documented OBS RTMP setup requires OBS 30.1 or newer and selects a hardware HEVC encoder; it also specifies Main 10, P010, and a Rec. 2100 PQ or HLG color space. Treat that as the requirements for the documented HDR workflow, not a rule for ordinary SDR streams. Check YouTube’s HDR live streaming instructions and confirm the encoder and application support the complete setup.

Troubleshoot common problems
| Symptom | Likely area to check | What to try |
|---|---|---|
| CPU overload or rendering/encoding lag | The CPU may be overloaded by x264 and the rest of the production workload | Test a supported hardware encoder, or reduce output resolution, frame rate, or workload; then repeat a representative test. |
| Hardware encoding does not improve the picture | Encoder generation, codec, bitrate, or settings may be limiting quality | Compare supported options at the same target bitrate and content; do not assume all hardware implementations are equivalent. |
| Dropped frames or poor stream health | The upload connection may not reliably sustain the chosen bitrate, or the system may be overloaded | Check YouTube’s stream health, test the connection under broadcast-like conditions, and lower the bitrate or output target if needed. |
| HDR option or stream setup fails | The selected codec, encoder, OBS version, or color format may not match YouTube’s HDR workflow | Verify HEVC support and each setting in YouTube’s HDR instructions, including the OBS version requirement for the documented RTMP setup. |
| The selected codec is missing | The device generation or application may not expose that codec in the chosen encoder | Check the device and application’s supported encoder options; choose a compatible codec rather than assuming codec availability from the hardware label. |
