Upload Speed
You should ideally be streaming over an Ethernet connection on a dedicated (unshared) network. Network speeds fluctuate constantly depending on numerous factors, so test your upload speed frequently.
In terms of your encoder's outgoing bitrate, you should set it to much lower than your available upload speed to allow for network fluctuations. Keep in mind other factors come into play when producing a stable stream, such as firewalls and network congestion.
2000kbps can produce a 720p stream whereas 5000kbps is the maximum bitrate we recommend for a 1080p stream. If you are streaming with a bitrate significantly less than 2000kbps, your stream may appear pixelated or experience lag.
Bitrate refers to the amount of data you send over to your website when streaming. Higher bitrates use up more of your internet bandwidth but at the same time, increasing bitrate can also improve your video quality. You shouldn’t overdo it though, as the increase in video quality is only beneficial up to a certain point.
As a rule of thumb, your bitrate should be less than half of your total upload speed, in order to have a stable stream. Streaming at a 1080p resolution needs a higher bitrate than streaming at 720p.
For guidance, you can check the following table to see what options to set:
| Upload Speed | Resolution | Bitrate |
| Under 1 Mbps | 360p | 300-800 kbps |
| 1.5 Mbps to 5 Mbps | 480p | 500-1500 kbps |
| Over 5 Mbps | 720p | 1000-3000 kbps |
| 10-20 Mbps | 1080p | 2000-5000 kbps |
Will my audience see my events in 1080p?
Your audience will be able to see your events in 1080p, as long as your source stream is outputting at 1080p and your audience has a strong network connection. If not, they’ll be served a stream at the quality appropriate to their device and bandwidth.
What network ports are needed to stream?
All encoders use various internet ports to communicate with ShowTix4U, all of which need to be made open to both incoming and outgoing communication.
These ports are:
- TCP 1935
- TCP 80
- TCP 443
- UDP 53
- UDP 2088 (if broadcasting from Mevo)
Ports 1935, 80, and 443 represent RTMP, HTTP, and HTTPS respectively. Many corporate and academic networks’ security policies will block UDP 53, as it provides DNS.
DP 2088 should be open when broadcasting from Mevo (iOS and Android). If any of these are blocked, you may want to get in touch with your network administrator or IT prior to proceeding further with setup.
Whitelist Domains
If your corporate network restricts access to certain websites or domains, ensure the following domains are whitelisted in order to communicate with ShowTix4U and its CDN.
- *.showtix4u.com
- *.vimeo.com
- *.vimeocdn.com
- *.google.com
- *.pndsn.com
- *.googleapis.com
- *.firebaseio.com
What bitrate should I stream?
2000kbps can produce a 720p stream whereas 5000kbps is the maximum bitrate we recommend for a 1080p stream. If you are streaming with a bitrate significantly less than 2000kbps, your stream may appear pixelated or experience lag.
What frame rate should I stream?
All live streams are transcoded to 30FPS.
