se6astian: the timeline shows beta development till end of 2014 - should it rather be up to 2015/Q1 - according to perk shipment? ( ref: https://www.apertus.org/axiom )
09:32
danieel
regarding the raw packing, one missed the point that there is no such thing as 4:2:2 RGB :)
09:32
danieel
all 4:2:2 recorders are taking YCbCr
09:46
danieel
and the last detail is bitdepth, with YCbCr 4:2:2 the usual external recorders handle 10bit nicely, so it averages at 20bit/pixel, but to be broadcast compatible, you cant use the bottom/top 4 codewords, so it is 19.98 bits effectively

This has probably been asked before... but why would someone prioritise purchasing an Axiom Beta over a Blackmagic Design 4K Camera ?
09:57
aquarat
apart from the open source nature of the Axiom Beta ?
09:58
aquarat
They seem to have the same sensor, one is in development, another is freely available
09:58
danieel
can bmd4k do 1080p120 if it does uhd@30? (bandwidth is same)
09:58
aquarat
no it can't
09:58
danieel
so that is the reason :)
09:59
aquarat
is that the only reason?
09:59
aquarat
:P
09:59
aquarat
it's a compelling reason...
09:59
danieel
one of the most obvious ones falling into category of free choice what to do with the hardware
09:59
danieel
and also easy to explain as the point is clear
10:00
aquarat
yes, the benefits of an open source product are profound
10:03
danieel
what do you shoot usually?
10:03
aquarat
a combination of tv commercials and health and safety videos
10:03
aquarat
it's a bit of a hobby of mine
10:04
danieel
to what gear currently?
10:04
aquarat
which tends to fit well with another hobby: electronics and PCs
10:04
aquarat
I have four BMD cameras
10:04
aquarat
and two Sony EX3s
10:04
danieel
same or diff?
10:04
aquarat
and three Sony NX5s
10:05
aquarat
same or diff ?
10:05
aquarat
I don't understand
10:05
danieel
the 4 bmds
10:05
aquarat
yeah, two 2.5k cams
10:05
aquarat
one 4k cam
10:05
aquarat
and the pocket cam
10:05
danieel
do they output same color instantly or needs lot of tuning?
10:06
aquarat
If the lighting is consistent one LUT can be applied to all footage from the 2.5k cams
10:06
aquarat
the 4k and 2.5k cams differ considerably in colour
10:07
aquarat
Generally we shoot raw, I debayer the footage (applying settings to achieve a neutral base to work from), I export to uncompressed YUV 422 10bit
10:07
aquarat
then I use ffmpeg to transcode the footage to multiple versions, generally rec709 proxy, 2k prores and 4k prores
10:08
aquarat
the 2k and 4k versions are in BMD's "Film" profile

aquarat: to add to the free choice you also have a clear upgrade path and a lot of flexibility with the AXIOM
10:15
se6astian
and a community surrounding it that will make it grow and glow over time :)
10:16
se6astian
plus we support fair labour and green sustainable manufacturing, BMD probably manufactures in China where it is cheapest
10:18
aquarat
cool, thanks for that se6astian
10:18
aquarat
yeah I don't get why companies like BMD and Canon don't open source their firmware
10:19
danieel
they would not sell as much new products :)
10:19
aquarat
hehe :P
10:20
aquarat
I like the presence of an arm soc in the beta
10:20
aquarat
this irc client is running on a quad-core arm unit
10:23
se6astian
nice :)
10:24
se6astian
well I already see the prime application for the AXIOM as on-set IRC chat platform :P
10:29
aquarat

Some geeky dops like to tweet, so could be great to have twitter feed notifications as well

Looking at twitter, https://twitter.com/search?f=realtime&q=apertus&src=typd the most mentionned article curently is this one : http://blog.planet5d.com/2014/09/magic-lantern-blackmagic-red-apertus-axiom/

I'll have a look if you want, Sebastian.
22:04

more collaborators, great :)

22:12
intracube
se6astian: just made the final change to the doc
22:12

not sure how to respond on the google doc chat - but it depends how informal se6astian wants it to read :P

"but feel â¬350 is too much of a commitment right now" - reads better, slightly less formal

yep, that reads ok

many thanks!
22:32
se6astian
posted now
22:35
intracube
as this is fairly important, maybe it could go on the main 'story' page
22:35
intracube
I suspect 90% of page views won't click on updates and will miss this info
22:41
theuberkevlar
Yeah if there is a way to put it on the main page I would recomment doing that. :)
22:43
se6astian
the perks are already on the main page
22:43
se6astian
I mean the tshirt/button designs
22:43
se6astian
and the 150⬠perk is available as well
23:10
se6astian
there is no designated "news" area on the frontpage, but thats what the update tab is for I guess
23:11
se6astian
released the campaign update on the mailing lists and social media
23:11
se6astian
now time for bed :)
23:12

have a good night then!

most of the sensor manufaturers struggle to make the sensors smaller
00:06
intracube
aombk: what do you mean?
00:06
intracube
or rather, what is this in reference to
00:07
aombk
no reference to anything, i just look into sensor manufacturers and their product lines
00:09
Bertl
it is kind of understandable
00:09
Bertl
making larger sensors costs a lot more
00:12
Q_
Why would you want a smaller sensor?
00:12
intracube
aombk: Samsung have a 16 megapixel sensor in the Note 4. the sensor must be pretty small.
00:12
intracube
Q_: you wouldn't! no shallow depth of field effect :)
00:12
Q_
I would like to see a 35 mm option. I think the biggest one is ASP-C?
00:13
Q_
s/ASP/APS/
00:14
intracube
the axiom beta will have the same sensor dimensions as the filmstock used in most hollywood films
00:14
intracube
aps-c is virtually the same as super35
00:15
intracube
if by 35mm, you mean 35mm still photography... that's different :)
00:18
intracube
VistaVision is the same format size as (D)SLR fullframe
00:18
intracube
and vistavision is not often used for movies
00:19
aombk
the thing is, some manufacturers that make tiny sensors, 1/4" - 1/11" or smaller use some very advanced techniques compared by the more "traditional" techniques used in large sensors
00:19
aombk
they do much research
00:20
intracube
aombk: I guess some of this tech will filter down to larger sensors, like sony's new a7s?
00:21
Q_
Calling it APS-C looks very confussing.
00:22
aombk
probably in time, large sensors will follow
00:22
intracube
aombk: http://www.youtube.com/watch?v=a1W-bPyYR0k
00:23
Q_
Afaik, in still photography 35 mm is 36x24mm, APS-C around 25x18 but depends on the manufacturer.
00:23
aombk
Q_, not really. your background is film?
00:23
intracube
1:18 onward
00:24
intracube
Q_: that's correct, afaik
00:24
aombk
Q_, when i get confused i visit wikipedia
00:24
aombk
https://en.wikipedia.org/wiki/Image_sensor_format
00:25
intracube
actual film is similar, but for still photography it's horizontal
00:25
aombk
intracube, i have seen this video yes the low noise at high gains is impressive
00:25
intracube
for movie film it's rotated 90 degrees to vertical
00:27
intracube
still FF (d)slr/vistavision: http://en.wikipedia.org/wiki/VistaVision
00:27
intracube
typical movie film: http://en.wikipedia.org/wiki/Super_35
00:27
Bertl
and to clarify, the CMV12000 has 22.5x16.9mm sensitive area
00:27
Bertl
the sensel are 5.5x5.5µm in size, 4096x3072 of them
00:27
intracube
movie film might historically have optical or magnetic sound area down one side
00:27
intracube
super35 doesn't
00:31
Q_
If you talk about 35 mm still photography, you're talking about: https://en.wikipedia.org/wiki/135_film
00:32
intracube
yup
00:33
Bertl
now twice wikipedia came to the rescue, we should consider donating to their cause!
00:33
Q_
Or: https://en.wikipedia.org/wiki/Full-frame_digital_SLR
00:35
aombk
i do donate to wikipedia every month
00:35
aombk
you dont?!
00:35
aombk
:P
00:35
Bertl
not yet, not on a regular basis, but I'm considering it
00:38
aombk
i see. yes, i was considering it too before i decided to do it
00:39
intracube
that reminds me. I should donate
