After seeing countless great presentations at SecKC, it was clear that a recording setup was needed to capture the wonderful content so it could be leveraged by others. I wanted to quickly document what we are using to record, in case it is helpful for others trying to record and distribute knowledge. Here is the setup we are now using to record SecKC video presentations.
It is surprisingly difficult to build a good presentation setup, at least for someone who isn’t an AV expert and doesn’t have an unlimited budget. IronGeek has documented some information, which he has used to record various conference presentations, although various pieces are out of date or in cases it’s unclear what exact part is needed and how it is hooked up. I tried to duplicate his general setup as closely as possible.
Note that all of the recording (this does the merging of signals) is done using Open Broadcaster (OBS) 32-bit (64-bit has issues with GCHD). Minimal post-processing (trimming and compression) is done using Windows Movie Maker.
On the laptop, there is the Canon EOS Utility to display the camera feed so it can be captured by OBS. From there, it’s a matter of getting everything configured in the software the way you want it.
A mid-grade laptop – I’m using an i3-4010U processor and I get 30FPS if I turn down the quality a bit.
Projector – Supplied by our event space
Video Camera – We use a Canon T3i
Sewell Direct SW-30008 Manta VGA to HDMI with 1080p Scaler (amazon)
- Use one with a scaler or else ElGato will reject your input signals
Podium Side-Mount Microphone Stand (MusiciansFriend) - Allows room for a laptop on podium
USB, HDMI, VGA, RCA, 3.5mm converters and cables, XLR, and 1/4″ cables.
Total = $880 + projector & speakers
If you want to see the results from this setup, here is the YouTube channel for SecKC: https://www.youtube.com/user/SecKCVids Note that at the time of this writing, the audio capture was just using the laptop microphone, and the quality will improve once it’s actually a wired setup.
Please let me know if this helps you or if you end up building one. I’d love to hear some feedback or ways to improve the setup.
