intracube
and some of the cameras from big name manufacturers have some rather odd design decisions
01:15
intracube
I was just looking at Sony's NEX-VG900 and it has a 24 megapixel sensor but has a maximum video res of 1920x1080
01:15
Bertl
you can't have enough megapixels on the paper :)
01:15
intracube
sure it takes stills, but that's not really the purpose of a camcorder, and then you get all the downsides of having to deal with those extra pixels
01:15
intracube
Bertl: true :( salesmen love it
01:16
intracube
VG900 seems to have quite noticeable moire/false colour issues and isn't that sharp
01:16
aombk
yes but videores needs a lot of processing and bandwidth thats why they dont use the full potential of the sensor
01:16
theuberkevlar

01:17
intracube
aombk: right, they can't. then suffer the consequences of poor downscaling. even though it takes nice, sharp stills...
01:17
aombk
sony charged 1000usd for a firmware update that unlocked 4k i think, some days after a hacker had unlocked that that feature
01:17
intracube
they should've put in a 3 or 4k sensor, properly downsampled
01:18
intracube
and would've got better low light as a bonus
01:18
aombk
before that, sony sold a much more expensive camera for 4k
01:18
intracube
heh
01:20
aombk
the thing is, corporations are a departments mess
01:20
aombk
they have very skilled technical departments but they dont make the decisions
01:21
intracube
yep, the marketing men do
01:21
aombk
yes and thats a pity.
01:21
intracube
or at least have too much influence
01:31
derWalter
so much to read again :D - nice!!
01:31
derWalter
btw... how will scottland vote, what do you think??
01:37
intracube
derWalter: it's going to be close. but the 'no to separation' votes have a slight lead
01:37
derWalter
looks like, yes :((
01:38
intracube
that's a bad thing? :)
01:39
intracube
even if you're in favour of separation, the forward planning if that were to happen is almost non-existent
01:40
intracube
imo if yes vote won, it should've been a staged separation over 10 years or so
01:40
intracube
but anyways, off topic :)
01:44
derWalter
mhhhhh the mp4 looks so much different from the original uploaded one....
01:45
derWalter
sometimes i miss the contrast, sometimes its to much (the grafiti scene)
01:45
derWalter
but nice grading in general
01:46
aombk
youre talking about the link i pasted?
01:53
intracube
aombk: did you add a mist filter to your grade?
01:54
aombk
yes, is it obvious or hard to spot?
01:56
aombk
gotta go. be back later. i intend to continue the grading of footage. so, any feedback appreciated
01:56
intracube
more noticeable on a few shots - the graffiti and owl
01:57
intracube
it doesn't look wrong
01:57
intracube
just stylised
02:02
intracube
I used a similar filter and dialled it up quite high on a couple of shots
04:04
derWalter
Bertl: what are you working on at the moment?
04:05
Bertl
a breakout board
04:07
derWalter
designing or welding?
04:08
Bertl
designing at the moment, I did some soldering a few hours ago :)
04:11
derWalter
hrhr :) i am just writing to pirate bay to promote the corwdfunding campaign
04:34
derWalter
und jetzt schreib ich noch vimeo an *fingers crossed*
04:50
derWalter
Bertl: wie lautet dem sebastian seine emailadresse?
04:51
derWalter
ah, now i start talking german cause its so late :D or would it better to use philippes email adress for contactinfo @vimeo?
04:52
Bertl
sp@apertus.org should be fine I guess
04:56
derWalter

aombk, I believe the term people use is "script-kiddy". If it really was as simple as danieel makes it sound.
14:32
theuberkevlar
It's a like a way of saying "wanna-be hacker"
14:33
Bertl
in any case, AXIOM Beta is for hackers and script-kiddies :)

I'm like a wanna-be script kiddie, I can follow instructions from a script-kiddie
14:39

danieel, that's really cool that the unlock is so simple
14:43
aombk
anyway, i have no problem with him, if some people want to call him script-kiddy or wannabe hacker or watever i dont care. he altered something in his proprietary camera and he unlocked locked features
14:44
danieel
he probably used an F55 formatted media in his F5 camera :)
14:46
danieel
anyway, the reaction of sony was good - better than in PS3 hack era

I saw the iphone can now shoot 4k :)
17:53
se6astian
and the app that does it costs only 1000$
17:53
Bertl
we should make an app which does 8k for only 1500 USD :)
17:54
Bertl
there is no limit to what interpolation can do :)
17:54

17:55
intracube
hi all
17:58
Bertl
hey intracube!
18:00
aombk
are you people aware of other options for field recorder
18:00
aombk
appart from atomos and blackmagic
18:01
intracube
hey Bertl :)
18:01
Bertl
se6astian: what was the gaming capture device which worked before the atomos?
18:04
aombk
Bertl, it captured to h264 or something?
18:04
Bertl
no, actually it captured raw data IIRC
18:13
se6astian
its called "elgato"
18:13
se6astian
it does capture H264
18:14
se6astian
but you can at least choose the datarate in their software (windows only of course) :)
18:15
Bertl
so it uses a hardware codec?
18:16
aombk
you tested it with alpha?
18:16

18:17
aombk
atomos products seem to be the only option atm
18:25
aombk
but they are not cheap
18:25
se6astian
aombk: yes with the alpha
18:25
se6astian
probably some h264 hardware encoding acceleration inside the device yes
18:26
se6astian
atomos are not the only option
18:26
se6astian
there are quite a few recorders out there
18:26
se6astian
and with hdmi to sdi converters even more
18:33
aombk
you think it will be possible to monitor the video and have zebras and focus peak etc with an android phone or tablet or there are limitations?
18:35
se6astian
there are no plans currently to stream video to an android device
18:38
Bertl
but it would be possible to do with a fast encoder (preferably on the arm cores) and some streaming protocol (RSP) plus an android app/applet of course
18:38
Bertl
just not something we will focus on
19:05
intracube
can you guys see any practical way of recording 120fps straight to h264?
19:05
intracube
is there any existing product that can do it?
19:06
intracube
if 50Mbit/sec is needed for decent quality 24p, then 120 would be something like 250Mbit/sec
19:07
intracube
all the proprietary devices seem to be limited to standard framerates
19:07
intracube
(**all the ones I've looked at)
19:08
wescotte
left the channel
19:09
intracube
HDMI/SDI interfaces would be a limitation I suppose
19:13
skinkie
intracube: at the IBC EBU meetup BBC showed that they used an AJA compressor at 8K resolution
19:16
intracube
skinkie: any idea what framerate?
19:21
skinkie
intracube: i know the NHK stuff is 120Hz but I guess BBC was doing 60
19:22
intracube
50Hz would be more likely for UK/EU equipment
19:32
danieel
intracube: there is a bitrate limit in h264 for each level... not sure if there is one covering 250Mbit
19:34
danieel
hardware encoders are usually 1080p30, with few exceptions which do 1080p60, and there are then some dsp's for multiple streams of that
19:37
intracube
I was wondering if it would be possible to distribute the raw frames across a number of hardware h264 encoders, then mux into a single stream
19:38
intracube
and it would need to be I-frame only
19:39
intracube
having a GOP structure with multiple h264 encoders likely wouldn't work
19:40
danieel
jvc did it that way for 4k/30
19:40
danieel
by quadrants and overlap
19:42
intracube
didn't they also split the encoded stream across multiple SD cards?
19:47
skinkie
intracube: i heard that Adtec was using a similar technique

i am very impatient i think i am going to get the 20k perk
20:24
aombk
will the whole team come to dinner?
20:27
Bertl
depends on where you live I guess :)
20:38
aombk
it doesnt say so in the perk description
20:43
intracube
the campaign needs more coverage! â¬2211/day avg will be needed to hit the target
20:43
intracube
unless aombk goes for the deluxe dinner date :D
20:47
intracube
sites like blendernation.com blenderaritsts.org would be worth posting to
20:47
intracube
anywhere where indie film makers lurk
20:48
intracube
assuming the site admins allow it
20:51
intracube
slashdot ?
20:53

I posted to slashdot
20:53

please feel free to repost :)
21:17

se6astian: oh ok. I'm just checking with google. maybe it isn't indexed yet
21:18

21:32

done
21:35
intracube
there was also this from 2010: http://hardware.slashdot.org/story/10/08/30/1639248/apertus-the-open-source-hd-movie-camera
21:36
intracube
a lot of the discussion focused on whether apertus would get hit my MPEG-LA/h264 licensing issues...
21:36
se6astian
yes there were lots of comments at the time
21:36
se6astian
lets hope people are still that interested in it now
21:37
se6astian
"Well, the name "Apertus" suggests it's supported by both Aperture Science and Hogwarts."
21:38
intracube
those mpeg-la comments are incorrect I assume?
21:38
intracube
since you won't be developing your own recording device for the Beta?
21:39
se6astian
and since we will avoid H264
21:43
Bertl
yes, I think slashdot, despite having lost a lot over the years, would be nice :)
21:44
Bertl
so maybe send them an email whenever you get around :)
