SkyDog & IronGeek

 I run Irongeek.com  I have an interest in InfoSec education  I don’t know everything - I’m just a geek with time on my hands  Sr. Information Security Engineer at a Fortune 1000  Co-Founder of Derbycon  Runs Skydogcon, Outerz0ne and is a volunteer/goon at Defcon, Shmoocon and many other cons  Got a real purdy mouth

Together Trevor and Adrian have had experience doing video at the following conferences: Skydogcon Derbycon Hack3rcon Outerz0ne Phreaknic BSides Las Vegas BSides Cleveland Notacon Louisville Infosec Shmoocon Firesides …and others we forget.

 We love sharing content  We run our own  Great advertisement for future cons  Professional houses are expensive  Faster turn around

 Simple  Sucks for slides  MiniDV used to suck for getting off the tape, but at least you could do direct capture on them

 HDMI or DVI  Both are digital, and electrically similar. SDI is also digital, but more for pro gear.  VGA and Component  Can look almost as good as HDMI  S-Video  Better than composite  Composite  Looks like crap Images from Wikipedia by Evan-Amos

 Martin does most of this at Derbycon, but here are a few recommendations  Make sure you have testing time  Small cons may work with ambient audio, but for large ones it sucks  Avoid long cable runs  Don’t have one cable on top of another, it may induce a current  Have devices plugged into same wall outlet (up to a limit)  Have converter cables for XLR to 3.5mm stereo  Audacity can work wonders

 Recording the conference is the middle part  Prep  Art needs to be ready before the con  Skelton web pages and bios  Pre-generated directories  Files with titles and file names  Training Volunteers  Get reliable video staff  Handout and video training  People will flake

 Live picture in picture rendering!  Open Broadcaster Software (OBS)  Faster and gives options to stream!  HDMI Capture on USB 2.0 devices is a few seconds behind so we had to add a delay

 VGA to HDMI scaler failed to convert a lot of laptops’ signals  EDID of projector vs. scaler may have been the issue  4x3 matted with black bars, which got compressed again because we expected to skew something 16x9 to 4x3  Long cable runs and lack of testing time may have caused the audio/ground noise we got  If the scaler failed with a given laptop, we went full screen with the camera, but composite capture sucked!  Fixing in post with raw capture would have been easier, but getting the whole con up would have taken longer

 AverMedia Live Gamer Portable ($157.99) REG/avermedia_c875_live_gamer_portable.html REG/avermedia_c875_live_gamer_portable.html  LKV351PRO VGA to HDMI Scaler ($51.99) (Having a problem getting the above scaler to work with AverMedia LGP)  Now I can ditch the composite capture device, take HDMI out of the camera into the Elgato and use LGP for capturing the presenter’s laptop Evan at Skydogcon is using:  Gefen EXT-VGAAUD-2-HDMIS VGA to HDMI Scaler ($187.76)  Blackmagic Design UltraStudio Mini Recorder Capture Device ($137.75)

 Elgato was slower to start, but lag was a more or less fixed amount  AverMedia LGP varied lag as time went on in OBS Other option to record speaker?  Logitech HD Webcam C P ($36.99)  Fast  Small (just one device)  Use sound card in laptop if you do not want ambient  Very compressed “1080p”  Limited zoom options

 Epiphan all in one box  Expensive, $1600+  Hopefully as more “Game” recorder systems come out this will be cheaper to do Skiboy.org: Failing since ONE Little Scooty Moulton shirt available at the HFC auction.

 Youtube  Get a director account  Archive.org  Borrow university bandwidth  Others  Blip TV  Vimeo

 Moving around a lot (We have to live with it)  Bring your dongles  Have you hooked your laptop to a projector before?  Rock the MIC (or at least speak into it)  Repeat audience questions  Please don’t show/say stuff that needs to be redacted  Client info  Doc on desktop

 Hacker con recording gear loaner program  We want to make a traveling box that we can send from con to con to record their talks  Adrian is planning to donate some old gear just to get it out of the house
