A List Of Items We Will Likely Want To Have

This is a list of items we will most likely need to live stream the conference and not want to pull our hair out while doing it!

• [x] Microphone(s)

  • Room tone microphone (so you can hear the audience laugh and clap)
  • Presenter microphone
  • Audience question microphone
  • Good to have backup presenter mics in case they break, especially for if we are doing wireless microphones!

• [x] Microphone Cable

  • You probably want XLR cable for your XLR mics
  • Same rule of backup cables applies, you never know!

• [x] Extension Cords

  • I should be able to bring a bunch, gotta have the cameras and equipment powered!

• [x] Microphone Mixer

  • I have a Shure M67 mixer which should work, it accepts 4 XLR inputs and I have a line out --> USB converter as well for input into the PC

• [x] Streaming PC

  The PC used for managing the streaming software likely needs to have the following items

  • Decent specs, requirements listed here, would be nice to exceed them ;P
  • HDD space or external drives, 1TB will be fine if we are not saving RAW video.
  • Two monitors (OBS or other streaming software on one monitor, other things on the other monitor, just trust me you will likely want more than one)

• [x] USB Line In Audio Interface

  • Takes line out from the mixer and sends it to the streaming PC over USB

• [x] 2(or more) Video Capture Cards

  • Currently we are going with @ASoTNetworks's Elgato HD60 and an AVerMedia Lite

• [x] Camera(s) that supports a live feed

  • Solid breakdown of what to look for in cameras here
  • @benhylau has a Panasonic HC V500 with HDMI output that should work

• [x] Tripod(s)

  • I have two nice metal tripods

• [ ] Video Splitter

  • Exact cable type is dependant on the venue
  • Sends video to the projector and to a capture card from the presenter laptop

I will add more items to this list if they come up / when I think of them. In the mean time, research begins!

I would also suggest adding an live video switcher with XLR mic input from the audio so you can switch between slide show and camera(s).

@darkdrgn2k mentioned that he will bring the VGA / Display Port / DVI to HDMI converter for connecting presenter laptops.

The audio and video data would need to go over HDMI to the computer for encoding and pushing it to the internet.

@ASoTNetworks will bring one Elgato HD60 and I want to purchase a second one. One for capturing the video camera HDMI output, the other for the presenter slides.

This eliminates the need for a HDMI switch, gives us parallel streams on the OBS interface. Also serves as backup if one card breaks, we can just give up one of the views.

We want to purchase this instead of rent so we can test the whole setup ahead of time.

[ASoTNetworks]

I forgot to mention I will also bring my laptop for OBS but I think we should have another laptop on standby if something goes wrong.

[darkdrgn2k]

If your ok without having the use of the laptop through all the conference days.

Otherwise we can probobly get another laptop.

[ASoTNetworks]

After doing some research apparently there are issues with the drivers that you cannot use 2 Elgatos capture card at the same time. https://obsproject.com/forum/threads/using-two-elgatos-at-the-same-time.41208/

The solution is most likely using another brand of capture card or an hardware HDMI switch.

Possible alternative is the HDPVR from hauppague

Also I never tried it but they do have HDMI to Component converters that would work with the HDPVR's i have

[darkdrgn2k]

Better solution would be to use a PC and an internal PCIe board like Hauppauge Colossus and avoid the usb bottleneck.

Waiting for site visit to confirm.

All set!
