|
| 23:42 | Bertl | alexML: maybe the dark frame is already clipped or distorted at the bottom end of the sensor linear range?
|
| 23:50 | jucar | joined the channel |
| 23:55 | Bertl | But even/odd delta as well as gain wouldn't be a big problem to correct for if they are constant

|
| 10:42 | Bertl | morning folks!
|
| 10:48 | alexML | morning
|
| 10:48 | alexML | Bertl: I found the answer
|
| 10:48 | alexML | when I averaged the dark frame, I subtracted the black reference columns from each image
|
| 10:49 | alexML | those columns have an offset between odd/even fields as well
|
| 10:49 | alexML | but - the value is different
|
| 10:49 | alexML | so, ignoring those black columns fixed it
|
| 10:51 | Bertl | ah, excellent
|
| 10:52 | Bertl | now I wonder what those black columns actually contain
|
| 10:52 | Bertl | in theory, they should behave identical to a photosite with the electronic shutter closed
|
| 10:53 | Bertl | i.e. they should do all the precharge, store, convert cycles except for the discharge one, which would be blocked
|
| 10:54 | alexML | I used them to autodetect the black level (took the median value from all of them)
|
| 10:54 | alexML | (it's not yet commited)
|
| 10:54 | alexML | btw, do you have any recent samples? with the latest sensor settings I only have the dark frames and the grey frames
|
| 10:56 | Bertl | currently I do not even have a working Beta, only parts for testing .... but Iriger has a working camera and has taken some samples with the latest register settings
|
| 10:56 | Bertl | probably best to contact him via e-mail at the moment
|
| 10:57 | alexML | I'm interested in samples with black offset greater than 2000 (the color charts have it at 1900, which is too low - clipped shadows)
|
| 10:58 | Bertl | the other working Beta should be back from 32c3 by now ... I presume se6astian and/or getzi has it
|
| 10:58 | Bertl | but it doesn't have the "latest" register settings apllied yet
|
| 10:58 | Bertl | (nevertheless, should be easy to adapt/add)
|
| 10:59 | Bertl | btw, we are working hard to get you folks your Betas as soon as possible.
|
| 11:00 | alexML | yay!

| 19:49 | comradekingu | http://nikonrumors.com/wp-content/uploads/2013/05/Nikon-F-schematics.jpg good old days schematics
|
| 19:49 | comradekingu | well, really an exploded view, but very nice at that
|
| 19:56 | davidak | when will you start working on the interface board and power board V2?
|
| 19:57 | davidak | is that planned before or after the next betas send out?
|
| 19:58 | Bertl_oO | new interface board design has already started
|
| 19:58 | Bertl_oO | power board V2 is definitely something for the next batch or maybe even later
|
| 19:59 | Bertl_oO | (requires a lot of testing before we can replace the current power board)
|
| 19:59 | davidak | and the "simple enclosure"?
|
| 19:59 | jucar | left the channel |
| 19:59 | Bertl_oO | you have to check with se6astian for that
|
| 19:59 | davidak | k
|
| 20:00 | davidak | so if these 3 things are completed i think i would order a beta
|
| 20:01 | davidak | so i have to make only software updates for some time
|
| 20:01 | Bertl_oO | so be it! :)
|
| 20:03 | davidak | it would be nice if you can update https://www.apertus.org/axiom-beta-roadmap daily if that doesn't prevent you from working on important things.
|
| 20:03 | davidak | like interface board -> started
|
| 20:05 | davidak | i'm not sure what recorder i will buy but i made some research already
|
| 20:05 | Bertl_oO | se6astian maintains this overview, but I will keep him informed
|
| 20:06 | davidak | should i have one that can actual record 4K60p or will that not be possible in the next time?
|
| 20:06 | Bertl_oO | well, 4k60p is not 4k60p :)
|
| 20:07 | Bertl_oO | i.e. depends on the compression and color encoding
|
| 20:07 | davidak | (and i think my computer is not able to edit that :D)
|
| 20:08 | Bertl_oO | we can currently do (with the "normal" HDMI modules) slightly over 1080p60 444 (i.e. 3 channels, 8bit)
|
| 20:08 | davidak | else this looks like a good device and is cheap here https://www.teltec.de/index.php?cl=details&cnid=92&anid=12248828-0&listtype=list&&sid=e84e2e85cf057e31517f3f5c7ce8c3de
|
| 20:10 | davidak | but i think i can't record in 720p120 on such devices
|
| 20:10 | davidak | that would be interesting for me
|
| 20:11 | davidak | my iPhone actual can :P
|
| 20:11 | Bertl_oO | that's the beauty of FOSS/OH and in this case the AXIOM
|
| 20:11 | Bertl_oO | even if the recorder doesn't support p120, you can record it
|
| 20:11 | davidak | but how long?
|
| 20:12 | Bertl_oO | all you need to do is rearrange the data to produce a format the recorder can capture
|
| 20:12 | davidak | ah ok
|
| 20:12 | Bertl_oO | simplest example, split 1080p60 in 4 parts
|
| 20:12 | Bertl_oO | and you get 540p240
|
| 20:13 | davidak | i understand
|
| 20:15 | Bertl_oO | granted 720p120 is a little trickier to arrange
|
| 20:19 | davidak | would you consider a 1080p30 recorder be a good companion for the axiom beta to use it's full potential?
|
| 20:19 | Bertl_oO | no
|
| 20:20 | Bertl_oO | as we have up to three HDMI outputs with 1080p60, you will be limited by the recorder
|
| 20:20 | davidak | what should i get to be future proof?
|
| 20:20 | Bertl_oO | doesn't mean that it won't work fine if all you want is FullHD
|
| 20:21 | davidak | 4K would be nice some time
|
| 20:21 | Bertl_oO | the best choice would be a recorder which can do multiple 1080p60 RGB uncompressed streams
|
| 20:21 | Bertl_oO | but I do not know of such a beast
|
| 20:21 | davidak | :D
|
| 20:22 | Bertl_oO | the second best choice is a recorder which can do 4k uncompressed/raw
|
| 20:22 | davidak | it would be very expensive
|
| 20:27 | davidak | maybe you can make a open hardware recorder in 4 years :)
|
| 20:27 | Bertl_oO | it is very likely that we will address the recorder side in the future
|
| 20:28 | davidak | do you think a recorder is hard to make?
|
| 20:28 | Bertl_oO | do you think a 4k camera is hard to make? :)
|
| 20:28 | davidak | i think harder than a recorder
|
| 20:30 | Bertl_oO | the main problem with recording are the proprietary interfaces which have to be controlled/utilized
|
| 20:30 | davidak | a recorder is just a computer and maybe a fpga for scaling that has some inputs and some outputs
|
| 20:30 | davidak | like HDMI and SATA
|
| 20:30 | Bertl_oO | a "computer" which handles SATA at enormous speeds
|
| 20:30 | davidak | and some software of course :D
|
| 20:30 | davidak | yes :D
|
| 20:36 | davidak | should i add a list of possible recorders i have found to the wiki or to my own website?
|
| 20:37 | Bertl_oO | IIRC, there is a wiki page for that, so it would be nice to extend that
|
| 20:37 | davidak | i will look at it
|
| 20:37 | Bertl_oO | https://wiki.apertus.org/index.php/HDMI/SDI_Recorder_Evaluation
|
| 20:37 | davidak | thanks and good night
|
| 20:37 | Bertl_oO | sleep well
|
| 20:37 | davidak | you too

|
| 21:45 | se6astian | with support material and angles, etc.
