What’s actually slowing this PC down?

For a pre-recorded video sent through YouTube Live at 720p and 50 fps, start with 8 Mbps for H.264 or 6 Mbps for AV1/H.265, using constant bitrate (CBR) and a two-second keyframe interval. These are practical starting points, not exact YouTube recommendations for 720p50: YouTube’s live bitrate table lists 720p30 and 720p60, but no 720p50 row. Applying the listed 720p values to 50 fps is an inference.
Recommended YouTube Live settings for 720p50
Use the resolution, frame rate, and bitrate that match the stream you intend to send. If your prepared video is 1280×720 at 50 fps, these settings are a reasonable starting point:
| Setting | Practical choice | What YouTube documents |
|---|---|---|
| Resolution and frame rate | 1280×720 at 50 fps | Set these in the encoder. The live bitrate table lists 720p30 and 720p60, not 720p50. |
| Video codec and bitrate | H.264: 8 Mbps AV1 or H.265/HEVC: 6 Mbps |
These are YouTube’s listed 720p30 and 720p60 values. Applying them to 50 fps is an inference. |
| Rate control | CBR (constant bitrate) | YouTube lists constant bitrate encoding for live streams. |
| Keyframe interval | 2 seconds | YouTube advises a two-second interval and says not to exceed four seconds. |
| Transport | RTMPS | YouTube recommends RTMPS for a secure connection. |
These figures refer to video bitrate, not total stream bitrate. YouTube’s live setup guidance separately specifies audio options: RTMP/RTMPS supports AAC or MP3, and 5.1 surround support is available only with AAC. Follow the audio settings supported by your encoder and intended output. See YouTube’s live encoder settings, bitrates, and resolutions.
First clarify what “pre-recorded” means
Playing a file as a live broadcast
If an encoder reads a prepared video file and sends it to YouTube as a live broadcast, use the live settings above. The fact that the video was recorded earlier does not make YouTube’s upload bitrate guidance the right setting for the live feed.
#1 Best Overall
- Based on 2MP monochrome (black&white) global shutter sensor OV2311, assembled with a 75°(H) low distortion M12 lens without IR pass filter, sensitive to IR.
- Global Shutter: Shoot high-speed moving objects in crisp sharp images. Avoid the rolling artifacts to get a much more accurate complete picture than the rolling shutter cameras. Reserved external trigger ports, support trigger via external signal.
- Resolution: 2MP 1600H x 1200V; Frame Rates: MJPG switchable, up to 50fps@1600 x 1200/1280 x 960/ 720P/800 x 600/640 x 480/320 x 240/160 x 120; YUY2 5fps@1600 x 1200/720P/800 x 600. Note: Please change the default frame rate of the software to meet your higher frame rate requirement.
- Plug&Play: UVC-compliant, just connect the camera to PC computer, laptop, Android device or Raspberry Pi with the USB cable without extra drivers to be installed.
- Applications: The sensor's high resolution and excellent low-light sensitivity, and low distortion lens make it offer exceptionally accurate gaze- and eye-tracking capabilities, highly recommended for Augmented and virtual reality, gesture and eye tracking, depth and motion detection.
Uploading a video normally
If you mean uploading the file as a regular YouTube video—not broadcasting it through Live—use YouTube’s separate upload guidance. It recommends uploading at the frame rate at which the video was recorded, lists 50 fps as a common frame rate, and gives 7.5 Mbps for 720p SDR high-frame-rate uploads (48, 50, or 60 fps). That 7.5 Mbps figure is an upload recommendation, not the live ingestion bitrate. See YouTube’s recommended upload encoding settings.
Choose a codec and bitrate your setup can sustain
Use H.264 at 8 Mbps if that is the compatible codec your encoder is set up to send. If your encoder and YouTube ingest setup support AV1 or H.265/HEVC, 6 Mbps is YouTube’s listed 720p value for those codecs. The table does not establish a special 720p50 bitrate for any codec; the 50 fps choices remain an application of YouTube’s 720p30/60 values.
Rank #2
- Compatible with Nintendo Switch 2’s new GameChat mode
- Crisp HD 720p/30 fps video calls with diagonal 55° field of view and auto light correction. Compatible with popular platforms including Skype and Zoom.
- The built-in noise-reducing mic makes sure your voice comes across clearly up to 1.5 meters away, even if you’re in busy surroundings.
- C270’s RightLight 2 feature adjusts to lighting conditions, producing brighter, contrasted images to help you look good in all your conference calls.
- The adjustable universal clip lets you attach the camera securely to your screen or laptop, or fold the clip and set the webcam on a shelf. You’re always ready for your next video call.
Whichever option you choose, check the encoder’s outgoing bitrate and make sure the connection can carry the total stream bitrate, including audio and any protocol overhead. YouTube recommends upload capacity with 20% headroom beyond the stream’s total bitrate. Its streaming tips advise testing upload capacity rather than relying on download speed, and accounting for other activity sharing the connection.
Preflight the live stream before relying on it
- Set the encoder. Enter 1280×720, 50 fps, the selected codec and practical bitrate, CBR, and a two-second keyframe interval. Select RTMPS where available.
- Check upload capacity. Run a speed test that measures upload speed. Leave YouTube’s recommended 20% headroom above total stream bitrate, and account for other devices or services using the same network.
- Test representative content. Send a test with movement and audio similar to the actual video; static footage alone may not reveal how the stream behaves on more demanding scenes.
- Check YouTube’s preview and health messages. In Live Control Room, confirm that the preview appears and monitor stream health and encoder messages. Fix warnings before the real broadcast.
- Allow time for setup. YouTube’s live streaming tips recommend setting up the encoder at least two hours before the event and starting it at least 15 minutes beforehand. See YouTube live streaming tips.
Troubleshooting bitrate and stream problems
Buffering, dropped frames, or unstable stream health
Check whether upload capacity is sufficient for the total stream bitrate plus 20% headroom. A speed test may not reflect capacity available during the broadcast if other network activity is consuming upload bandwidth. Reduce competing traffic or choose a bitrate the connection can sustain, then test again.

- UVC compliance for use in OS Windows, Linux, Android, Mac
- OTG support
The encoder will not accept the selected codec
Confirm that both the encoder and the YouTube ingest configuration support the codec you selected. If AV1 or H.265 is unavailable in your setup, use H.264 and its listed 720p starting point of 8 Mbps.
The stream looks poor even though the bitrate is set correctly
Verify that the source is actually 1280×720 at 50 fps and that the encoder is not unintentionally changing its frame rate, resolution, or rate-control mode. Compare the Live Control Room preview and health information while sending representative motion and audio; the bitrate alone cannot confirm that the complete encode is configured as intended.
