For a conventional H.264 YouTube news stream, a sensible starting profile is RTMPS, CBR, a 2-second keyframe interval, 1080p at 30 fps, and 14 Mbps video. If your production connection cannot sustain that rate, test 720p30 at YouTube’s recommended 8 Mbps instead. These are YouTube recommendations—not an India-specific preset or a guarantee of uninterrupted streaming. Astra’s channel controls and the encoder settings sent to YouTube do different jobs, and the right Astra configuration depends on your actual source and output chain.
Start with the YouTube output profile
Choose the codec, resolution, and frame rate for the feed that reaches YouTube, then set the corresponding bitrate. YouTube’s published H.264 recommendations, accessed October 3, 2026, are:

| Output format | Recommended H.264 video bitrate |
|---|---|
| 2160p at 60 fps | 35 Mbps |
| 2160p at 30 fps | 30 Mbps |
| 1440p at 60 fps | 24 Mbps |
| 1440p at 30 fps | 15 Mbps |
| 1080p at 60 fps | 17 Mbps |
| 1080p at 30 fps | 14 Mbps |
| 720p at 60 fps | 8 Mbps |
| 240p–720p at 30 fps | 8 Mbps |
These are YouTube’s H.264 recommendations, not measured results for an Indian channel or a particular network. Use the H.264 column for an H.264 output; do not substitute figures from YouTube’s separate AV1 or H.265/HEVC ranges. The platform also supports H.265/HEVC and AV1 video, up to 60 fps, but the appropriate rate depends on the selected codec and format. See YouTube’s live encoder settings for current guidance.

1080p30 at 14 Mbps is a reasonable first profile when your encoder and production connection can sustain it. It provides a clear HD picture without requiring the higher video bitrate of 1080p60. For fast-moving footage, compare 1080p60 at 17 Mbps during testing; higher frame rate can make motion smoother, but it also raises the required bitrate. If the connection struggles at 1080p30, try 720p30 at 8 Mbps rather than running an unstable higher-rate stream.

Encoder and audio settings
- Delivery: Use RTMPS where available for secure delivery.
- Bitrate mode: Use constant bitrate (CBR).
- Keyframes: Set a 2-second interval; YouTube says not to exceed 4 seconds.
- Video: For SDR, use Rec. 709 color space and 8-bit depth.
- Stereo audio: YouTube lists 44.1 kHz and 128 Kbps.
- 5.1 audio: YouTube lists 48 kHz and 384 Kbps.
- Audio codec: YouTube lists AAC or MP3 as options.
These are platform specifications, not a verified Astra preset. Confirm that the encoder or relay actually sending the feed to YouTube applies them.
Choose a rate your Indian connection can sustain
YouTube does not publish a separate bitrate preset for India. Your location and ISP matter because the configured upload rate must be maintained continuously, but no single speed threshold is established as reliable across Indian providers and regions. Measure the actual production connection, test at the intended bitrate, and leave practical headroom for normal variation rather than treating a brief speed test as proof of 24/7 capacity.

News output can vary significantly: a static studio shot and a fast-moving field report do not place the same demands on encoding quality. Test representative footage, including the busiest motion and the audio setup you expect to use. YouTube advises: “Make sure to test before you start your live stream.”
Understand what Astra controls—and what it does not
Cesbo Astra handles media streams: it receives content from configured sources, processes it, and delivers it to clients. Astra’s channel behavior is separate from the video codec, bitrate, keyframe interval, and delivery protocol configured in the encoder or relay feeding YouTube. The official Astra documentation does not establish a universal direct YouTube RTMPS route or a field-by-field Astra-to-YouTube profile. Your system may use a separate encoder or relay, so identify the actual chain before copying settings into an application.

Review demand-start and keep-active behavior
Astra’s general settings provide global defaults unless an individual stream overrides them. Relevant options include “Start stream on demand” and “HTTP Keep Active.” Astra documents that an HTTP Keep Active value of zero turns a channel off immediately when its last client closes the session. For a continuous workflow, check that demand-start and keep-active behavior fits the configured source and output; these controls do not set YouTube’s encoder bitrate.
Saving Astra general settings restarts Astra, so plan a change around the channel’s maintenance window rather than applying it casually during a live broadcast. See Astra general settings.

Check per-stream monitoring and backup delays
Astra’s advanced stream settings include “Enable monitoring,” on-demand start, and “Keep Active.” With on-demand mode enabled, Astra waits for an incoming request before starting a stream; Cesbo notes that on-demand start is turned off for channels with UDP or HLS outputs. Confirm the specific stream type and output before relying on those options. Review the configured backup start and return delays against your source design as well. Astra’s monitoring and source behavior are not the same as YouTube’s ingest health. See Astra advanced stream settings and Cesbo Astra documentation.
Recommended Free Tools
Test the whole chain before scheduling continuous output
- Map the signal path. Identify the source, Astra stream, any encoder or relay, and the component that sends the feed to YouTube. Record where each setting is applied.
- Select the YouTube format. Choose codec, resolution, and frame rate for the outgoing feed before setting its bitrate. For an H.264 first test, use 1080p30 at 14 Mbps if the connection can sustain it, or 720p30 at 8 Mbps as a lower-rate option.
- Configure the encoder. Set RTMPS, CBR, a 2-second keyframe interval, and the appropriate audio and SDR values listed above. Confirm the settings on the actual YouTube-bound encoder or relay.
- Check Astra channel behavior. Review demand-start, keep-active, monitoring, and backup delays in the relevant global and individual stream settings. Make sure they match the source and output type.
- Run a representative preflight. Test the intended connection with realistic motion and audio before committing to a long broadcast. Check the resulting picture and sound, and monitor YouTube stream health during the test.
- Secure the stream key. Treat it as a credential: it tells the encoder where to send the feed and allows YouTube to accept it. If it is compromised, reset it in YouTube Live Control Room and update the encoder.
Monitor health and diagnose interruptions
YouTube Live Streaming API stream states include ready, active, inactive, created, and error. Health warnings can include low video bitrate and video ingestion starvation, which mean YouTube is not receiving enough video for smooth streaming. A healthy YouTube ingest does not by itself prove that the Astra source is healthy, so monitor both ends of the chain. See YouTube Live Streaming API stream health documentation.

Common symptoms and fixes
| Symptom | What to check | Practical response |
|---|---|---|
| YouTube reports low video bitrate | Whether the source, encoder, or network is delivering the configured rate consistently. | Check the outgoing encoder settings and connection; if the link cannot sustain the selected profile, test a lower resolution or frame rate with its corresponding YouTube bitrate. |
| YouTube reports video ingestion starvation | Whether video is arriving too slowly or intermittently at YouTube. | Inspect the complete source-to-ingest chain, including Astra source status, encoder output, and the production connection; monitor health during another representative test. |
| Astra channel stops when no client is connected | Demand-start and HTTP Keep Active settings, including stream-level overrides. | Check the general and individual stream configuration against the intended continuous output workflow. |
| Backup input behaves differently from the primary | Whether the two ingests use matching codecs, bitrates, frame rates, and keyframe frequencies. | Align the primary and backup configurations; YouTube’s API health guidance flags differences in these settings as configuration issues. |
| YouTube will not accept the feed | That the correct stream key is in the YouTube-bound encoder and has not been reset or exposed. | Verify or reset the key in Live Control Room, then update the encoder with the current credential. |
