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
VGA and Component
Can look almost as good as HDMI
S-Video
Both are digital, and electrically
similar. SDI is also digital, but
more for pro gear.
Better than composite
Composite
Looks like crap

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

Skelton web pages and bios
Pre-generated directories

Live picture in picture rendering!
Open Broadcaster Software (OBS)
http://obsproject.com
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
http://Irongeek.com
http://Skydogcon.com
Canon Consumer Camcorder (VIXIA $300 to $400)
Elgato Game Capture HD ($157.99)
http://www.bhphotovideo.com/c/product/879363REG/Elgato_Systems_10025010_Game_Capture_HD_High.html
2X2 SVGA VGA MATRIX Switcher ($28.05)
http://www.monoprice.com/products/product.asp?p_id=4083
STC-250N for composite out of cameras ($14.95)
http://www.bhphotovideo.com/c/product/184982REG/Canon_3067A002_STV_250N_Mini_A_V_Angled.html
be careful what you get!
VGA to HDMI Scaler $31.79
Video Capture Dongle S-Video/Composite
http://www.monoprice.com/products/product.asp?p_id=5616
Tripods
http://Irongeek.com
http://Skydogcon.com
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)
http://www.bhphotovideo.com/c/product/983193REG/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)
http://Irongeek.com
http://Skydogcon.com
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 C615 1080P ($36.99)
Fast
Small (just one device)
Use sound card in laptop if you do not want ambient
Very compressed “1080p”
Limited zoom options

Expensive, $1600+
Hopefully as more “Game”
recorder systems come out
this will be cheaper to do
