lcaav-c1ryan here, that opsis is definitely dodgy.  i managed to completely break C1 by unplugging cables and had NFI what cables went where.  it's fixed now with original opsis but have swapped opsis's.  all is in order though on the podium & in voctomix00:13
lcaav-c1let me know if the issue keeps occuring.  the opsis both seemed fine to me00:13

*** clive_murphy-av has quit IRC02:01
xfxfreminder: if you have a 'false' start (i.e. you hit cut, then there's problems which get sorted out, and then the talk starts), do a cut again and note it on the sheet02:08
xfxfwe ideally want a start 'cut' which is where the talk starts.  if you miss it all good - we can fix, but the videos go up quicker the less editing we're doing02:09
tumbleweedit never hurts to cut too many times02:12
*** BenTom has quit IRC02:12
tumbleweedextra cuts give the editor options later02:12
*** BenTom has joined #lca-av02:13
tumbleweedalso, cut after the applause, please02:13
tumbleweeda few talks seem to end a little suddnely02:13
lcaav-c3sorry... :/02:13
lcaav-c3will fix on future talks02:14

rjhw@xfxf C3 next talk we have been asked not to stream live.02:23
xfxfSure - put it on stream loop02:23
xfxfMake sure the presenter knows to let the conference organisers (not us) know if they don't want their talk released, so they can update the schedule data02:24
xfxf(They may already have revoked permissions in their dashboard - in which case, that's all we need)02:25

tumbleweedxfxf: ^^02:33
clive_murphy-av*laptop (without 3.5mm out)02:34
xfxf-phoneyou can't. It's 3.5mm only02:34
xfxf-phoneThe workaround is the handheld mic near the laptop02:34
clive_murphy-avcool. will do.02:35
tumbleweedor borrow a USB -> 3.5" sound card02:35
tumbleweed3.5mm even02:36
xfxf-phoneAlso all: people who aren't speakers shouldn't be coming in during breaks and running impromptu sessions using microphones and projectors. They can use the space, but there's no AV. Make sure you all get breaks please :)02:36
tumbleweedfeel free to redirect things like this to the test station02:36
tumbleweedthis is why the test station exists02:36

BenTomfyi we don't appear to have a room monitor in c203:53
BenTomprobably not necessary for miniconfs, but dunno if there should be regardless03:54

BenTomall good, they're here now04:07
xfxfhey all, i'm writing up the room allocations now and noticing a few issues04:07
xfxfdo we have anyone from A2 who would be happy to join C1 instead for Wed > Fri?04:07
xfxfalso, Harry (please someone ack if he can see this / has been told), I've put you into C2 for Wed > Fri if that's OK04:08
lcaav-a2(harry) fab04:09
xfxf(people in A2 tomorrow are Clive, Courtney and Tahlia)04:09
lcaav-a2i shall ask tahlia04:10
xfxf(but we only have 2 in C2 - it's best to have only 2 in A2/A3 because it will get rather hot in the back room with more people and it's quite small back there!)04:10
xfxfthanks.  if you'd all prefer to stay there that's OK too, but see above :)04:10
lcaav-a2yep04:10
xfxfif any of you have the link on your phone you're welcome to look at the spreadsheet I emailed out, it's updated04:11
xfxfi'll avoid pasting the link here because we shouldn't open the web browser on the recording machines (can cause issues)04:11
lcaav-a2ack04:11
lcaav-a2tahlia will move to c104:24
xfxf-phoneno worries - thankyou04:25
lcaav-a2all good04:25

lcaav-a2_We have an issue where we only get audio from laptop (3.5mm) and we only get projectors for hdmi19:55
keeperlcaav-a2_: Please elaborate, what do you expect to happen, and what's happening instead.19:56
xfxf-phonethat is normal - audio over HDMI won't work, you have to use the 3.5mm cable..19:56
xfxf-phoneI'll come over to A2 soon though19:57
BenTomwhen HDMI is selected on the lecturn the projectors work, when laptop is selected the projectors stop working but the 3.5mm audio works19:58
BenTom(a2)19:58
xfxf-phonehmm, something changed then. Will get AV tech to come over and look19:59
xfxf-phoneCan you stay there?19:59

tumbleweedI've freeed 93G an C1 by deleting after-hours video20:11
xfxf-phoneHi all, we're starting to notice prod uction issues in recorded videos nobody reported to us.  Audio problems (wear your headphones while mixing always!!), slides or camera being left on for over 5 minutes without switching, etc20:17
xfxf-phonePlease make sure you are always paying attention - it's easy to get engrossed in the talk and forget to look at the mixing computer or the camera20:18

lcaav-a2_xfxf-phone: we've got a hiss in a2; doesn't appear to be mics or 3.5mm20:38
xfxf-phonewhat happens if you mute all 3 inputs?20:39
lcaav-a2_nice, it was the lecturn20:39
lcaav-a2_... which is already removed - should we just keep it muted?20:40
tumbleweedyes, mute it20:41
xfxf-phoneYa keep it muted. This goes for all rooms20:44
xfxf-phoneAssume phantom power on that line is causing the sound20:45
thepatr1ckxfxf-phone: has dynamic contrast ended up on again in C1?20:47
pavelowYeah, not much contrast on the dark images on the slides20:48
tumbleweedthey've encoding the HDMI signal down to something for the long runs (over ethernet), it looses some detail (and dynamic range, by the look of it)20:51
xfxf-phoneCan someone take a photo please20:53
xfxf-phoneOf both projectors20:53
