Telemetry is the automatic recording and transmission of data from remote or inaccessible sources to a system in a different location for monitoring and analysis. It means our system probes your encoder, monitors the health of your stream, then reports it back to us automatically to present to you.
โ
To find your stream telemetry report, navigate to the recent live stream in your Dashboard and click over to "Live" at the top of the item.
You will see the "Broadcast Rating" preview and can click on it to view full telemetry.
What's in the Report?
Your telemetry report will include a detailed breakdown of all the parts that make up your stream. Each piece of your broadcast is compared to what the best setting should be, then graded based on how close you came to the target.
โ
There will be three sections in the report each with their own rating of Excellent, Fair, or Poor depending on recommended settings.
Broadcast info
Rating - Health of your stream based on bitrate, resolution, and encoding settings. Incorrect settings and disconnects can lead to a poor rating. Dig into these metrics to improve your overall stream health. Learn more
Recommended: Excellent
Resolution - Dimensions of your broadcast in pixels. Anything outside of a 16:9 or 4:3 ratio is considered a poor viewing experience. If connection bandwidth is a concern for either your encoder or your viewers, a resolution of 1280x720 with the minimum bitrate would be the best choice.
Recommended: 1920x1080 or 1280x720
Frame rate - Video frame rate of your broadcast in frames per second (fps). Constant frame rates of 23.976, 24, 25, 29.97, and 30 fps are supported.
Recommended: 30.00 fps
Duration - Total duration of stream(s) that occurred during your broadcast, including any reconnects. To see the number of disconnects, see Broadcast metrics.
Recommended: Ensuring a continuous stream for the entirety of your scheduled broadcast.
Broadcast metrics
Video Bitrate - Average video bitrate of your broadcast in Kbps (kilobits per second). Based on your resolution, your video bitrate is then compared against the most optimal settings.
Recommended: Determined by resolution. Learn more
Audio Bitrate - Average audio bitrate of your broadcast in Kbps (kilobits per second). Based on your resolution, your audio bitrate is then compared against the most optimal settings.
Recommended: Determined by resolution. Learn more
Video Bitrate Variance - The degree at which the video bitrate fluctuates throughout your broadcast. A variance above 750 Kbps is considered poor. Many factors, such as an unstable internet connection, can contribute to a higher bitrate variance. Learn more
Recommended: Below 500 Kbps
Audio Bitrate Variance - The degree at which the audio bitrate fluctuates throughout your broadcast. A variance above 10 Kbps is considered poor. Many factors, such as an unstable internet connection, can contribute to a higher bitrate variance. Learn more
Recommended: Below 5 Kbps
Disconnects - Total number of disconnects that occurred during your broadcast. Even a single disconnect is considered poor. An unstable internet connection, high CPU, and power outages are the most common reasons for disconnects.
Recommended: 0 Disconnects
A/V settings
Video Coding Standard - H.264 has been industry-standard for some time. There are other video coding standards available but only H.264 is compatible with Subsplash Live.
Recommended: H.264
Audio Coding Standard - AAC has been industry-standard for some time. There are other audio coding standards available but only AAC is compatible with Subsplash Live.
Recommended: AAC
H264 Profile - The profile is a combination of several different complementary parameters within the H.264 coding standard. Using the right profile is important to making sure your stream is as widely-compatible as possible.
Recommended: Determined by resolution. Learn more
Audio Sample Rate - Audio sampling is the process of converting analog audio from mics and instruments into a digital signal using samples, and the sample rate describes how frequently samples are taken. 48000 Hz is the standard sample rate for most online content.
Recommended: Determined by resolution. Learn more
The level setting is used by decoders (i.e., viewers' devices) to know how much performance is required in order to play the stream successfully. Using the right level is important to making sure your stream is as widely-compatible as possible.
Recommended: Determined by resolution. Learn more
The report is color-coded. Anything in green means we're using optimal settings and had minimal interruptions or errors. Anything in red or yellow should be addressed in your encoder to make sure your stream is performing as best as possible.
