#apertus IRC Channel Logs

morning folks!

So i told this environmental agency about the apertus merits in terms of ethical production and sourcing. However, the current landing page says nothing about that, so it can't be featured. Is this information displayed anywhere?

comradekingu -> https://www.apertus.org/opensource -> "Professional Manufacturing"

"what we care about" does it for me

It doesnt say anything about conflict materials, regulations, contracts, programs, nothing

It just strikes me as unprofessional

https://www.apertus.org/opensource to say it as honestly as possible, is just not cutting mustard

hi BAndiT1983

how is it going?

have you read the long email?

monitoring IRC, lab and my mails through the day

regarding MXF

camera doesn't really need to make those inside... given the document

just want to ensure some things, as the discussions turn always to advanced formats, but the focus should be on the required data

I PM'ed you a link

i know the specs, at least to some level

MXF should not be hard.. given it is jst a KLV format storage

it doesn't answer my point, what we should get from the camera and in which format

there are many formats out there, but first we need the data as some package which comes from the camera

(initial metadata)-(data)-(data)-(mode change meta)-(data)-(data) etc

in anycase... I would recomment this data not to be kept as is... and should be converted to anything like XDNG before it hits post

there are a lot of things which can be calculated from meta data and image data, so we should grab as more as possible for later processing

[as more as possible for later processing] -> this was one of the issues

but MLV does not have that

why do you care about GPS currently?

we could embed custom tags or re-use existing ones

[why do you care about GPS] -> more of other things... such as lens info (which is currently under discussion in MLV)

[and what is the problem with that? if we convert it afterwards in right format for CDNG or MXF etc., then there is not much issue] -> just wanted to know if this was on table, or we were to ship MLV directly to post

i would go for conversion, because current hardware would struggle a bit with advanced stuff

afterwards we can re-use the modules on the camera

a good direction to look into

but doesn't that lead to whole plethora of new problem why we create specs like MLV in first place?

stereoscopic data would include 2 streams or one with alternating sensor data

yep

i would go with XMP file, which would be merged with video stream later to MXF, CDNG etc.

one for data, other for things other than data?

just ideas, as direct output would be nice, but also requires a lot of testing in-camera

on fast lane

this would allow to sync packets between the two comm channels

the two channels as in :[https://trello.com/c/aX7KJihl/24-the-planned-usb3-recording-pathway] ?

unordered frames maybe, so the output doesn't lag

these serial numbers can be quite cyclic, however should be distinguishable

or you can read the order out of the XMP meta data

preview with frame server would also be possible, don't see any issues there too

data is written in the right order of frames, with id/hash, frames get same id, but related to them

and mapping operation be done based on hash or ID?

don't think, that they will be off by far in the stream, also it's not the final word, that any disorder would be there, just throwing some considerations from MLV format

isn't (data/id stream) + (XMF) the idea now?

XMP can be transferred over ethernet, as it can be written more slowly, and MLV was just an example for frame disorder

ARRI foramt specification are available? I would like to look at it

don't think so

the format is proprietary?

:) XD

I would fly to get hold of your computer now BAndiT1983 ? :) [file:///C:/Users/Andi...]?

don't know if there is open info or just an overview

not the way they record it...

but wiki mentions some tool which can read the tags from ARRIRAW

yes

CDNG what has to be collected: pg24, how MXF is (FWIW): pg14, still would look into ARRIRAW, but basic tags would be more or less the same

ARRIRAW seems to be proprietary, other google links sugest that too

Image Orientation _> maybe this: Bertl once told me that data could be mirrored

any advantage or purpose?

Moreover, some way to encode if it was an electronic shutter or physical shutter (so we have both in camera)?

maybe also, ways to encode external systems: remote shutter / WiFi module / Flash system

:) in any case... an extensibel XMF should do fine in that case

BAndiT1983: can we three have a meeting on Sunday... ?

I am home... please decide a time that suits you

[anything after 12] -> timezone +1 UTC?

ah, it's utc +2

if it's not too late for you, then ok

no need to, as it's usual time when i do some stuff for apertus on sunday

I will inform g3gg0

i would be off for now.. have a great day
