Another Hawaii Tech Tuesday live event but for the first time, we steamed it at 1080 via You Tube Live Event, using OBS software to mix three video sources locally and upload to you tube using only 1 machine. A few glitches but overall we are pleased with the capability. We used an AverMedia Broadcaster HD to capture VGA video from a pass through connection on the projector in the room. Our primary (presenter) video was via USB utilizing a Logitech C920. The in-room Q&A camera was a Canon HV20 video camera capturing images at 1080i which connected to the single host PC via USB3 where an AverMedia ExtremeCap u3 external video capture device completed the video inputs. Audio captured through our Mackie ProFX 8 mixer which was selected as a mic source within OBS.
Now that we've reduced the number of machines from 3 to 1, our 5 mbps uplink is more than sufficient. OBS wasn't breathing hard at all.

Some latency. Is this fully processed?
ReplyDeleteDan McDermott we streamed this at 1080 and for the vast majority of the event, the lights were all green and zero dropped frames (30 fps). At one ponit for some inexplicable reason the lights were flickering yellow and red, then back to green. Afterwards I found out that while we were upstreaming the event one of our members strolled across the hall and started watching it on the live stream (effectively robbing us of bandwidth!) That may well have been what caused the weird episode mid show.
ReplyDeleteAlso, I need to play around with the OBS mic sync settings so that the lips are in sync with the audio.
I'd be interested to hear your feedbahtck and any tips you might have. We have to set up and break down for each event, and for each event so far we've been working with new gear and/or techniques so experience level is low. more opportunity to practice would help.
right after we stopped streaming i went to view the you tube video and it was limited to 480 resolution. later i could select 720 or 1080. however when selecting it from some posts I not that the highest selectable resolution is 480 again.??
John Brown Gotcha. It may very well be the processing. It takes a while sometimes for YouTube to fully lock it in. A lot of that is because of the DVR ability viewers have while it is live and for a few hours afterward.
ReplyDeleteDan McDermott call me crazy but after 48 Hours, I'm detecting a significant reduction in the disparity between spoken word and lip movement. Don't let me influence your opinion, but please take a second look and tell me if you too see an improvement.
ReplyDeleteLooks about the same to me. It's worse in the beginning, not to bad as you get deeper in.
