| 17:58 | max_bxl | hello everyone !
|
| 17:59 | Bertl | hey max_bxl!
|
| 18:00 | se6astian|away | changed nick to: se6astian
|
| 18:00 | se6astian | good evening
|
| 18:00 | se6astian | meeting time
|
| 18:01 | Bertl | \o/
|
| 18:01 | max_bxl | do we have a list of topics ?
|
| 18:02 | se6astian | please message me now with a pm if you want to report something in the meeting
|
| 18:04 | se6astian | ok Bertl please go ahead with your report
|
| 18:04 | se6astian | I have the feeling this will be a brief meeting today :)
|
| 18:04 | max_bxl | seems so
|
| 18:05 | Bertl | okay, I did some work on the test setup and we had some problems with what seems like defective PCBs there
|
| 18:05 | Bertl | problem is still open because we are out of PICs at the moment
|
| 18:06 | Bertl | replacement types have been ordered and will be tested in the next few days though
|
| 18:07 | Bertl | the mechanical trimmers which always caused headaches on the power board have been discontinued, so we are currently working on a replacement there
|
| 18:08 | 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
|
| 18:08 | Bertl | and of course, a lot of tests on the software side, because sooner or later we need to rework the firmware part
|
| 18:09 | Bertl | that's basically it from my side
|
| 18:09 | max_bxl | ok I take it from here
|
| 18:10 | max_bxl | I met Pierre Prégardien, who is planning to make a feature film just with open source tools
|
| 18:10 | max_bxl | so he thought he can use an AXIOM !
|
| 18:11 | max_bxl | his idea is to develop the tools in the same time as the script is developped
|
| 18:12 | max_bxl | and he's planning a shooting in 18 months, maybe two years
|
| 18:13 | 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)
|
| 18:14 | max_bxl | the DOP on the project was also there
|
| 18:14 | max_bxl | we discuss what kind of "improvement" they'd need to welcome the AXIOM on a set
|
| 18:15 | max_bxl | and they are preparing a list that I'll share (hopefully soon)
|
| 18:15 | Bertl | sounds great!
|
| 18:16 | 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)
|
| 18:16 | max_bxl | and so on...
|
| 18:17 | 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.
|
| 18:17 | se6astian | sounds good
|
| 18:18 | 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?
|
| 18:18 | max_bxl | and then they will try to find the money to pay for the work !
|
| 18:18 | max_bxl | @se6astian : yes and no
|
| 18:19 | 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
|
| 18:20 | se6astian | of course
|
| 18:20 | se6astian | sounds good
|
| 18:20 | max_bxl | moreover, they have hints on where to find subsidies for "innovation" and stuff like that ^^
|
| 18:21 | se6astian | and your role is to form the bridge between their team and the AXIOM community right?
|
| 18:21 | max_bxl | yes, it sounds good
|
| 18:21 | max_bxl | as always !
|
| 18:21 | se6astian | great :)
|
| 18:22 | max_bxl | basically, I see it as two good opportunities
|
| 18:23 | max_bxl | 1) to have requests and feed-back from a feature film crew that is understanding open source
|
| 18:23 | max_bxl | 2) have more people involved in the developpement of the camera (I guess mainly software and GUI)
|
| 18:24 | se6astian | and 3) a film created with open source tools and the beta :)
|
| 18:24 | max_bxl | of course !
|
| 18:24 | se6astian | topic concluded?
|
| 18:25 | se6astian | is there anything we can help with currently?
|
| 18:25 | se6astian | or are we waiting for the list first?
|
| 18:25 | 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
|
| 18:25 | max_bxl | we are waiting for the list I guess, and then questions will arise
|
| 18:26 | se6astian | great
|
| 18:26 | se6astian | a "reduced story complexity" is definitely a good choice for such an adventure
|
| 18:27 | se6astian | quick update from me:
|
| 18:27 | se6astian | 1. the integrating sphere is operational, herbert provided me with two sensor front end pcbs and 2 image sensors
|
| 18:28 | se6astian | we will capture a set of test images with every SFE and every sensor
|
| 18:28 | se6astian | then add one component to the PCB and redo these tests
|
| 18:28 | se6astian | then add another component and run the tests again
|
| 18:28 | se6astian | then add a couple more components and redo the tests again
|
| 18:28 | se6astian | the goal is to find out how these changes affect image noise profiles
|
| 18:29 | se6astian | the "best" board will then get into production
|
| 18:29 | max_bxl | very interesting !
|
| 18:29 | max_bxl | everything will be documented on the wiki I guess ?
|
| 18:30 | se6astian | alexML: will conduct the analysis and surely will share them on the wiki
|
| 18:30 | se6astian | not sure if we will be able to share the entire snapshot archive, each run will produce several GBs of data
|
| 18:31 | se6astian | 2. team talk released successfully, feedback so far was mild but good
|
| 18:31 | max_bxl | sure
|
| 18:31 | se6astian | max will start editing TT 13.2 next week
|
| 18:32 | se6astian | 3. the powerboard is currently undergoing the planning of a redesign so we started collecting things we want to change/improve yesterday
|
| 18:33 | se6astian | we will summarize these changes in the coming days on the wiki
|
| 18:34 | se6astian | 4. We got 2 HP proliant servers donated
|
| 18:34 | se6astian | they are around 5 years old but in top condition
|
| 18:34 | max_bxl | maybe now is the right moment to talk about this 12V Pierre and his DOP discuss about ?
|
| 18:34 | se6astian | without HDDs though
|
| 18:35 | se6astian | its not decided yet where we can utilize the servers yet though
|
| 18:35 | se6astian | and how
|
| 18:35 | se6astian | ideas welcome
|
| 18:35 | se6astian | thats it from me
|
| 18:36 | se6astian | if there are no more topics we can conclude this weeks meeting and discuss the 12V topic sure
|
| 18:36 | se6astian | next meeting in 2 weeks again as always if there are no objections
|
| 18:38 | Bertl | should be fine here
|
| 18:39 | se6astian | great
|
| 18:40 | max_bxl | yes that's it for the meeting I guess
|
| 18:40 | se6astian | so max_bxl what exactly is pierre planning with 12V batteries?
|
| 18:40 | Bertl | an why does he have a non UTF character in his name?
|
| 18:41 | max_bxl | é ?
|
| 18:41 | se6astian | meeting minutes posted: https://wiki.apertus.org/index.php/IRC_Team_Meeting_2017-09-25
|
| 18:42 | Bertl | sec, maybe just my terminal is weird
|
| 18:42 | 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
|
| 18:43 | max_bxl | directly on the main battery, which is also powering the camera
|
| 18:43 | max_bxl | it saves the need of multiple batteries : one (big) battery to rule them all
|
| 18:44 | Kjetil | I guess they use this xlr-like 4pin connector
|
| 18:45 | se6astian | so its a convenience feature but not a must-have?
|
| 18:46 | max_bxl | convenience, yes
|
| 18:46 | max_bxl | but also a way to make it friendlier to the professionnal users
|
| 18:47 | max_bxl | (so it's less DSLR-like)
|
| 18:48 | se6astian | right
|
| 18:48 | Bertl | Prégardien (just checking)
|
| 18:48 | 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
|
| 18:49 | 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
|
| 18:49 | se6astian | like being able to record 4k uncompressed raw
|
| 18:49 | se6astian | or higher framerates, etc.
|
| 18:49 | se6astian | camera enclosure
|
| 18:50 | se6astian | axiom remote
|
| 18:50 | se6astian | camera REST API
|
| 18:50 | se6astian | webgui
|
| 18:50 | se6astian | wifi out of the box
|
| 18:50 | max_bxl | yes sure
|
| 18:50 | Kjetil | SDI :)
|
| 18:50 | se6astian | exactly :)
|
| 18:51 | 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
|
| 18:51 | max_bxl | speaking of SDI
|
| 18:52 | max_bxl | I know why HDMI was developped first
|
| 18:52 | 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?
|
| 18:53 | 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
|
| 18:53 | max_bxl | but when cinema people see HDMI they immediately think of problems
|
| 18:54 | Bertl | we alread tested this with those car USB adapters which work just fine
|
| 18:55 | Kjetil | I guess you would need a buck-boost type converter as I guess their battery is only nominally 12V
|
| 18:55 | Bertl | well, the Beta input is 5V so I think a buck will suffice
|
| 18:55 | Kjetil | Ah
|
| 18:59 | se6astian | max_bxl: what questions/thoughts did the Pierre team have? Did we cover the topic suffieciently?
|
| 19:02 | se6astian | ok I am afk for a bit
|
| 19:02 | max_bxl | I think
|
| 19:02 | max_bxl | *I think we covered it sufficiently for now
|
| 19:03 | max_bxl | my remarks where more about some feedbacks I hear from people outside the apertus community
|
| 19:04 | max_bxl | let's see what are their needs first
|
| 19:33 | max_bxl | gotta go
|
| 19:33 | max_bxl | see you folks !

| 00:14 | rton | 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.
