good morning :)

who is here?

seems we will be quick today again :)

not really

so quick updates from me:

new recorder enclosure 3d print parts (we are at version 0.2 ) have been produced and I am putting the recorder together to test as we speak

and he is in full swing editing already

with all the inserts to add we might not make it but 1 or 2 days shall not be an issue hopefully

anuejn completed new additions to the axiom recorder to do realtime debayering of A+B frames from HDMI stream

directly on the lattepanda recorder hardware

directly in dng then though

what we have in raw12 currently basically

well dng is also raw :)

any noise correction could potentially be done in a better way if there is more cpu power available

as the axiom recorder can already read raw12 sequences now so it would be possible to apply the corrections later (not from hdmi source but filesource) as well

there was also the question if the raw12-viewer is obsolete now and I concluded that the axiom-recorder has a slightly different goal so I/BAndiT1983_ will continue working on it

vup: we discussed yesterday if the corrections are reversible but concluded: "not entirely" right?

se6astian: well only darkframe, dcnu frame and gainframe should be reversible (apart from maybe rounding errors)

more interesting is the dark column based row noise filtering, but worst case I think we just need to save 2xheight extra values to make it reversible

(very important in making it reversible is of course using the same *frames to undo the correction, but we probably can just save a checksum of them or something like that to catch mismatches)

maybe saving them on the camera? So you can not easily loose them

true

(Bertl: also yes in general I completely agree with you about only doing corrections we can (easily) reverse if we only save a corrected image)

is that expected?

will take picture

cool

unfortunately I think the color filter array is not configured correctly in the dngs currently

well anuejn did not push the changes :(

right

that looks interesting

you noticed the penguin immediately didnt you? :D

debayering?

but the color effect seems to be motion related

oh yeah se6astian: do you get any output on stdout?

(it should print a message if it detects a mismatched / dropped frame)

using gpu: intel...

it did report 2 slipped frames

but I noticed similar artifacts on the raw12 sequences recorded when played back with the axiom recorder

oh interesting

when we tested it on saturday we also had some motion related color artifacts, but they looked a bit different, but until those are fixed, I would just assume its the same artifact you are seeing

they appear much finer and less severe when the screen is fullhd like the material

this lcd is 1024x600 IIRC

yeah maybe, we can try with screen scaling and see what happens

So I finally did the finishing touches on https://github.com/apertus-open-source-cinema/pcbs

atm it just generates the preview images, the gerbers and pdf version of the schematics

nice

https://github.com/openmoko/openmoko-usb-oui/pull/37

yes!

does the conversion work automatically or did you have to drag it through kicad manually?

the one I linked can be generated using a ulp script from eagle

would be a nice addition to the pcb page IMO

to add a new board one should just need to drop a `.brd` and a `.sch` into this folder: https://github.com/apertus-open-source-cinema/pcbs/tree/main/boards

(best with accompanying .license files)

thats it from me

right then, off to dinner as well

many thanks everyone!

hey, changes for dng recording are pushed

cool
