10 Commands of Streaming
Ignore at yourPeril
1. You Shall Test early & Test often
Test
With the actual gear
From the actual location
With the actual subject matter
Setup and go live early
Test early & test often (con..)End-to-end tests are bestTest on-site actual bandwidth & actual
source signal Test with moving images from live
cameras Test audio syncWatch your test on all end user devices
(Desktop, iPads, etc.)Monitor throughout the live event
2. You Shall Know your upload bandwidth
Speedtest.net – test it and Re-test More bandwidth is better Dedicated bandwidth Maximum headroom – 2x over the “target
bitrate
How much bandwidth?
Upload is what matters
For HD, at least 3MbpsAbove shows a typical residential gradeLow quality streaming can be done@ 800kbps
Recommended settings
Quality Resolution Video Bitrate RecommendedBandwidth
HD 1280 x 720 2 Mbps 4Mbps
High 960 x 540 1.5 Mbps 3Mbps
Medium 640 x 360 1 Mbps 2Mbps
Low 480 x 270 400 Kbps 1Mbps
3. You ShallHave great lighting
One overlooked is great lighting
With poorly lit scene, your camera will introduce noise into the video pictureThis noise is amplified by the video encoding process, resulting in a low-quality, VHS-like image
4. You Shall Have great audio
The second secret is great audio.
A presentation that you can’t see but can hear is valuable A presentation that you can see but can’t hear is uselessGet direct feed form PA system,
on-board mic often poor sound USB sound is much better than 3.5 jack
5. You Shall remember Long form content works best
Forget web video 2-3 minutes long
Short form works well for VOD, live streams less than 20 min will have a hard
time attracting an audience
6. You shallCreate page for your event
Create a Clear dedicated streaming page Have relevant content around the
player Schedules, background information, calls
to action
7. You ShallMake it interactive
Take advantage of the flexibility of this medium
Behind-the-scenes, interactive chats / Q&A with real-time questions form the audience via TwitterStream as long as possible this helps to generate more social buzz
8. You ShallGo live early
Start your stream 15-40 minutes early
Allows you time to make sure everything is working correctly end-to-endViewers will show up and spread the word
9. You shallKeep on streamin’
Re-stream as live or make the VOD available ASAP! (Check with Copyright issues)
The best window of time to gain maximum audience is immediately after the live event ends Publish where rebroadcast can be found
10. You ShallPromote your event
Promote at least 3 different times and at least 3 different ways.
One week before, one day before, one hour before, 5 minutes before liveUse email, social media, pre-registration and call attendees Request influential or high profile participants tweet it
