For a 1080p prerecorded video at 29.97 fps, use YouTube’s published 1080p at 30 fps settings as the closest documented target: 14 Mbps recommended for H.264 or 10 Mbps for AV1/H.265, with CBR and a 2-second keyframe interval. YouTube does not publish a separate 29.97 fps row, so check the encoder’s actual output and inspect the Live Control Room preview before going live.
Recommended YouTube Live settings for 1080p at 29.97 fps
YouTube’s encoder settings table specifies 1080p at 30 fps, not 29.97 fps. The values below apply that 30 fps guidance as the closest published category; YouTube’s documentation does not specify fractional-frame-rate ingest, pulldown, or a universal frame-conversion method. The settings are input recommendations, not a guarantee of picture quality for every source, encoder, or connection. YouTube’s encoder settings provide the current table.
| Setting | YouTube guidance for 1080p at 30 fps |
|---|---|
| Video bitrate, H.264 | 5 Mbps minimum; 14 Mbps recommended |
| Video bitrate, AV1 or H.265/HEVC | 4 Mbps minimum; 10 Mbps recommended |
| Rate control | CBR |
| Keyframe interval | 2 seconds recommended; do not exceed 4 seconds |
| Protocol | RTMP or RTMPS; YouTube recommends RTMPS for encryption in transit |
| Video format details | Square pixels, progressive scan, 2 B-frames, 1 reference frame, CABAC |
| SDR color | Rec. 709, 8-bit |
| Stereo audio | AAC or MP3, 44.1 kHz; 128 kbps recommended |
| 5.1 surround audio | AAC; 48 kHz and 384 kbps recommended |
If the encoder offers 29.97 fps, do not assume it is interchangeable with a 30 fps output setting. Keep the file and output frame rate aligned where possible, then confirm what the encoder actually sends and check for judder, dropped frames, and audio sync in the preview. YouTube says resolution and frame rate are automatically detected by default. If you need to select resolution manually, create a custom stream key and enable manual settings under Stream Resolution. YouTube’s encoder settings instructions explain those controls.
Plan upload bandwidth and test the actual file
Use the bitrate recommendation for the video codec you selected, and make sure your available upload capacity is higher than the stream’s total bitrate. YouTube recommends leaving 20% of available upload bandwidth unused as headroom. The total includes audio as well as video, so do not size the connection from video bitrate alone. YouTube encoder settings and its streaming tips cover the recommended bitrate and bandwidth headroom.

ZowieBox, 4K HDMI NDI Video Encoder/Decoder, HDMI NDI
- Compact but Powerful Design: ZowieBox is smaller than a phone, featuring a tally light and LCD screen for streaming status. Capture console gameplay in up to 4K with zero-lag HDMI passthrough, while the built-in video encoder converts video for IP streaming. The IP stream can also be decoded back to a 4K HDMI signal.
- Standalone Game Streaming: Just plug and play—ZowieBox enables PC-free live gaming without affecting gameplay. As an RTMP hardware encoder and HDMI streamer, it delivers stable streaming directly from your source, making it ideal for gaming, live events, and professional broadcasting.
- NDI|HX3 Converter Technology: ZowieBox converts HDMI signals to NDI|HX3/HX2/HX, functioning as an NDI video encoder, or NDI Video Decoder for flexible IP workflows. Certified NDI technology enables low-latency gameplay streaming through OBS/vMix. Note: Encoder and decoder modes cannot run simultaneously; full NDI signals are not supported.
- UVC to HDMI Conversion: Supporting up to 4K@30fps and 1080p@60fps decoding, ZowieBox enables flexible conversion for webcam and video workflows. As a video decoder and HDMI to IP converter, it expands connectivity options for professional video devices. Note: USB capture card functionality is not currently supported.
- All-around Configuration Options: Control ZowieBox through its web UI on a PC, phone, or tablet. Manage connected PTZ cameras, tally light, video/audio, OSD, work mode, streams, network, and system settings. Support for VISCA over IP encoder workflows enables flexible PTZ control, while the dashboard provides video preview and system status.
- Test before the event using the same file, motion, and audio you intend to broadcast.
- Check framing, movement, sound level, and audio/video synchronization in the Live Control Room preview.
- Verify the local recording if your encoder saves an archive, and test watch-page playback on the devices viewers are likely to use.
- If you rely on backup-encoder failover, test the changeover before the event.
- Monitor stream health and messages throughout the broadcast; a bitrate value alone cannot diagnose every connection or playback problem.
YouTube’s streaming tips specifically advise testing in advance and leaving upload headroom. YouTube Help streaming tips.
Schedule the stream and connect the encoder
- In YouTube Studio, open the Live Control Room and schedule a stream or create one. Scheduling can create an upcoming watch page that viewers can share and use to set reminders. See YouTube’s guide to creating a live stream with an encoder.
- Copy the stream URL and stream key from YouTube into your encoder. Treat the key like a password: it authorizes the encoder to send a feed. If it is exposed, reset it in Live Control Room. See YouTube’s stream settings guidance.
- Set the encoder’s output resolution and frame-rate behavior for the prepared file, then configure it to play the file. Exact media-source and looping steps depend on the encoder; YouTube’s help pages do not define one universal prerecorded-file procedure.
- Start sending the feed early enough for YouTube to receive it. Wait for the Live Control Room preview, inspect picture and sound, and use Go live when the scheduled stream is ready.
- Keep the stream health panel in view during the event and monitor the encoder and connection.
For rules on encoder connection and previewing a feed, see YouTube’s live stream setup guidance.

Playing prerecorded content: what depends on your encoder
The bitrate and signal recommendations above do not explain how to feed or loop a media file. Choose an encoder that can play the prepared video, and follow that encoder’s documentation for adding the file as a source, setting playback behavior, and repeating it if needed. Test the complete playback path before the event. YouTube’s reviewed help pages do not establish one file-playback workflow for every encoder, nor do they specify how every encoder handles 29.97 fps.
Troubleshoot common setup problems
| What you see | What to check |
|---|---|
| The stream will not connect | Confirm the encoder has the correct YouTube stream URL and current stream key. If the key was exposed or may be wrong, reset it in Live Control Room and update the encoder. |
| Resolution or frame rate differs from the source | Check the encoder’s actual output settings and the stream preview. YouTube’s published target is 1080p at 30 fps; it does not give a distinct 29.97 fps row. |
| Video stutters or stream health reports trouble | Compare the encoder’s codec, bitrate, and CBR setting with the applicable YouTube row. Check available upload capacity and preserve the recommended 20% headroom. |
| Audio is missing, distorted, or out of sync | Check the encoder’s audio codec, sample rate, and bitrate against YouTube’s audio guidance, then test the same file and playback path again. Inspect both the preview and the encoder’s local archive if available. |
| The video looks juddery | Confirm whether the encoder sends 29.97 or 30 fps and whether it converts the source. YouTube does not prescribe a universal fractional-frame-rate conversion; test representative motion in advance. |
These checks narrow down common causes; YouTube’s guidance does not give a single diagnosis that applies to every dropped-frame, judder, or sync issue.
