Why Your Video is Blurry
A blurry video stream can typically happen for two reasons:
Reason 1: Poor bandwidth
If your bandwidth suffers during an event, this can lead to pixelated video quality. Your upload speed should be at least 5 Mbps, but 10 Mbps upload is recommended. We highly recommend working through this technical checklist before going live with your event. If possible, use a wired ethernet connection.
Reason 2: Your computer's processing power
Some machines may be underpowered or slowed down by certain processes like other applications running in the background. We recommend you close all unnecessary applications and close down unneeded tabs.
You can also try lowering your computer's screen resolution to help boost performance. You may also consider a browser that uses less RAM if your computer is overworked, but we do still recommend using a Chromium-based browser.
Reason 3: You're on a shared network
Network performance can change over time and activities like Netflix, streaming, gaming or file syncing within your household or office can affect your available bandwidth. If the connection is marginal, streaming quality will be affected when you click "go live".
What's Happening When Your Video is Pixelated
A pixelated video is usually the result of an inconsistent bitrate or spikes in packet loss. Bitrate involves the speed at which your video is transmitted. Packet loss indicates that errors occurred while data was transmitted across your wireless networks. Inconsistency in either bitrate or packet loss will result in connectivity disruptions and lagging.
When packet loss exceeds a minimum threshold, Crowdcast will automatically turn off the video stream and drop down to audio-only, so your attendees don't experience lagging and pixelation.
How Toggling HD Video During a Live Event can Help
When streaming live on Crowdcast using the in-browser method and not RTMP Studio, you'll see an HD icon when you hover over your screen which allows you to stream in HD.
When the icon is red, HD is off and you're streaming at a resolution of 480p.
When the icon is green, HD is on and you're streaming at a resolution of 720p.
If you're experiencing issues with pixelation, toggling HD off may produce a better quality stream.
To stream up to 720p you have to have a camera that supports it. Most modern webcams and laptops support a 720p resolution, but if yours doesn't, you may also need to toggle the HD option off.
Crowdcast saves the settings from your most recent session, so you only need to set it once. Your settings will stay the same for your next event.
