hello everyone !

hey max_bxl!

se6astian
good evening
17:00
se6astian
meeting time
17:01
Bertl
\o/
17:01
max_bxl
do we have a list of topics ?
17:02
se6astian
please message me now with a pm if you want to report something in the meeting
17:04
se6astian
ok Bertl please go ahead with your report
17:04
se6astian
I have the feeling this will be a brief meeting today :)
17:04
max_bxl
seems so
17:05
Bertl
okay, I did some work on the test setup and we had some problems with what seems like defective PCBs there
17:05
Bertl
problem is still open because we are out of PICs at the moment
17:06
Bertl
replacement types have been ordered and will be tested in the next few days though
17:07
Bertl
the mechanical trimmers which always caused headaches on the power board have been discontinued, so we are currently working on a replacement there
17:08
Bertl
I also spent some time on creating a test lighting solution for the integration sphere and two test SFEs (complete with sensors) for testing
17:08
Bertl
and of course, a lot of tests on the software side, because sooner or later we need to rework the firmware part
17:09
Bertl
that's basically it from my side
17:09
max_bxl
ok I take it from here
17:10
max_bxl
I met Pierre Prégardien, who is planning to make a feature film just with open source tools
17:10
max_bxl
so he thought he can use an AXIOM !
17:11
max_bxl
his idea is to develop the tools in the same time as the script is developped
17:12
max_bxl
and he's planning a shooting in 18 months, maybe two years
17:13
max_bxl
which let's him plenty of time to find people to work with and gather a team to developp all what he need for his movie (from the camera to the colorgrading solution)
17:14
max_bxl
the DOP on the project was also there
17:14
max_bxl
we discuss what kind of "improvement" they'd need to welcome the AXIOM on a set
17:15
max_bxl
and they are preparing a list that I'll share (hopefully soon)
17:15
Bertl
sounds great!
17:16
max_bxl
for example : could the Beta be powered by a 12V battery (which is the usual voltage for a lot of cinematic gears and accessories)
17:16
max_bxl
and so on...
17:17
max_bxl
so when we'll have the list, we can tell them : "this improvement is possible but take 3 weeks full time to developp" etc.
17:17
se6astian
sounds good
17:18
se6astian
and did I understand it correctly that they are also willing to spend time and find developers to work on solving these things themselves right?
17:18
max_bxl
and then they will try to find the money to pay for the work !
17:18
max_bxl
@se6astian : yes and no
17:19
max_bxl
they are willing to find money to pay people to solve the problems, so it can be someone in the community or someone that will be joining the community
17:20
se6astian
of course
17:20
se6astian
sounds good
17:20
max_bxl
moreover, they have hints on where to find subsidies for "innovation" and stuff like that ^^
17:21
se6astian
and your role is to form the bridge between their team and the AXIOM community right?
17:21
max_bxl
yes, it sounds good
17:21
max_bxl
as always !
17:21
se6astian
great :)
17:22
max_bxl
basically, I see it as two good opportunities
17:23
max_bxl
1) to have requests and feed-back from a feature film crew that is understanding open source
17:23
max_bxl
2) have more people involved in the developpement of the camera (I guess mainly software and GUI)
17:24
se6astian
and 3) a film created with open source tools and the beta :)
17:24
max_bxl
of course !
17:24
se6astian
topic concluded?
17:25
se6astian
is there anything we can help with currently?
17:25
se6astian
or are we waiting for the list first?
17:25
max_bxl
last thing : the plot seems rather simple (one actor, one closed setting) so it will provide safe environnement to work with a beta
17:25
max_bxl
we are waiting for the list I guess, and then questions will arise
17:26
se6astian
great
17:26
se6astian
a "reduced story complexity" is definitely a good choice for such an adventure
17:27
se6astian
quick update from me:
17:27
se6astian
1. the integrating sphere is operational, herbert provided me with two sensor front end pcbs and 2 image sensors
17:28
se6astian
we will capture a set of test images with every SFE and every sensor
17:28
se6astian
then add one component to the PCB and redo these tests
17:28
se6astian
then add another component and run the tests again
17:28
se6astian
then add a couple more components and redo the tests again
17:28
se6astian
the goal is to find out how these changes affect image noise profiles
17:29
se6astian
the "best" board will then get into production
17:29
max_bxl
very interesting !
17:29
max_bxl
everything will be documented on the wiki I guess ?
17:30
se6astian
alexML: will conduct the analysis and surely will share them on the wiki
17:30
se6astian
not sure if we will be able to share the entire snapshot archive, each run will produce several GBs of data
17:31
se6astian
2. team talk released successfully, feedback so far was mild but good
17:31
max_bxl
sure
17:31
se6astian
max will start editing TT 13.2 next week
17:32
se6astian
3. the powerboard is currently undergoing the planning of a redesign so we started collecting things we want to change/improve yesterday
17:33
se6astian
we will summarize these changes in the coming days on the wiki
17:34
se6astian
4. We got 2 HP proliant servers donated
17:34
se6astian
they are around 5 years old but in top condition
17:34
max_bxl
maybe now is the right moment to talk about this 12V Pierre and his DOP discuss about ?
17:34
se6astian
without HDDs though
17:35
se6astian
its not decided yet where we can utilize the servers yet though
17:35
se6astian
and how
17:35
se6astian
ideas welcome
17:35
se6astian
thats it from me
17:36
se6astian
if there are no more topics we can conclude this weeks meeting and discuss the 12V topic sure
17:36
se6astian
next meeting in 2 weeks again as always if there are no objections
17:38
Bertl
should be fine here
17:39
se6astian
great
17:40
max_bxl
yes that's it for the meeting I guess
17:40
se6astian
so max_bxl what exactly is pierre planning with 12V batteries?
17:40
Bertl
an why does he have a non UTF character in his name?
17:41
max_bxl
é ?
17:41
se6astian
meeting minutes posted: https://wiki.apertus.org/index.php/IRC_Team_Meeting_2017-09-25
17:42
Bertl
sec, maybe just my terminal is weird
17:42
max_bxl
as I was never a good 1AC, I rely on his DOP remarks : lots of cinema accessories (motorized follow focus for example) are 12V powered
17:43
max_bxl
directly on the main battery, which is also powering the camera
17:43
max_bxl
it saves the need of multiple batteries : one (big) battery to rule them all
17:44
Kjetil
I guess they use this xlr-like 4pin connector
17:45
se6astian
so its a convenience feature but not a must-have?
17:46
max_bxl
convenience, yes
17:46
max_bxl
but also a way to make it friendlier to the professionnal users
17:47
max_bxl
(so it's less DSLR-like)
17:48
se6astian
right
17:48
Bertl
Prégardien (just checking)
17:48
max_bxl
it's a matter of perspective I guess, but the more "details" like this we can feature, the more "pro" the camera will look like and eventually it'll be used on regular production because cinema people feel confortable
17:49
se6astian
the question though for me is if this is something they consider important to spend time and money on at this point, from our perspective I would say there are far more important things to take care of
17:49
se6astian
like being able to record 4k uncompressed raw
17:49
se6astian
or higher framerates, etc.

17:50
se6astian
wifi out of the box
17:50
max_bxl
yes sure
17:50
Kjetil
SDI :)
17:50
se6astian
exactly :)
17:51
max_bxl
I just mentionned it the first time because I remember it and the second time because we were discussing of power board changes
17:51
max_bxl
speaking of SDI
17:52
max_bxl
I know why HDMI was developped first
17:52
se6astian
Bertl: to my understanding DC/DC conversion would be a separate PCB connected to the powerboard. Is there anything the powerboard redesign could cover to make a 12V supply easier/better currently?
17:53
Bertl
I don't think we want to put a specific converter on the power board (for several reason) but there is no problem with having an efficient external converter
17:53
max_bxl
but when cinema people see HDMI they immediately think of problems
17:54
Bertl
we alread tested this with those car USB adapters which work just fine
17:55
Kjetil
I guess you would need a buck-boost type converter as I guess their battery is only nominally 12V
17:55
Bertl
well, the Beta input is 5V so I think a buck will suffice
17:55
Kjetil
Ah
17:59
se6astian
max_bxl: what questions/thoughts did the Pierre team have? Did we cover the topic suffieciently?
18:02
se6astian
ok I am afk for a bit
18:02
max_bxl
I think
18:02
max_bxl
*I think we covered it sufficiently for now
18:03
max_bxl
my remarks where more about some feedbacks I hear from people outside the apertus community
18:04
max_bxl
let's see what are their needs first
18:33
max_bxl
gotta go
18:33
max_bxl
see you folks !

Hm moving layer folders which have file layers takes really long in 3.3.0. It took around 2 minutes for the "moving nodes" operation to complete.
