Delivering live video - workflow

Humble Beginnings• OK to start small

– Started with USB Cameras and Free software• Flash Media Live Encoder• Ustream Producer free

– Leaders don’t always get vision • Demand will often grow

– So will expectations

– Be fun, grow your team– Evangelize to “tech” minded/curious– “Beta”- allows trial-and-error

GCA Equipment List

Streaming Mistakesin order

• No plan –make a list check it twice …– Sample on website

• Poor audio• Poor lighting• Poor camera techniques

Production 101• Constantly Strive to Improve • Know and understand the roll of each

team member• Plan, research, and prepare for success• Have a vision• Make a check list for consistent

experience

Team WorkGetting it Done

atmosphere• Provide leadership & direction• Allow crew to troubleshoot• Be in control (but not a freak) • Trouble shoot challenges & technical

issues

10 Commands of StreamingIgnore at your

Peril

1. You Shall Test early & Test often

Test With the actual gearFrom the actual location With the actual subject matterSetup 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 3MbpsExample above shows a typical residential gradeLow quality streaming can be done@ 800kbps

Recommended settingsQuality Resolution Video Bitrate Recommend

ed Bandwidth

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 on the camera will not pick well USB sound is much better than 3.5 jack

5. You Shall remember Long form content works bestForget web video needing to be 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
