se6astian: do you know what Beta version means? :) it is untested final product.. not a development gear
16:02
Bertl
you know what Alpha version means? :)
16:07
danieel
the FAQ is misledading, 4k over 1 sdi is possible
16:08
se6astian
which question?
16:08
danieel
for 4K you need at least Quad-SDI so thats 200$ just for these parts already.
16:12
se6astian
thanks, fixed
16:12
danieel
even worse
16:15
danieel
and DSLRs are not professional either, the whole answer is unclear
16:16
danieel
6G SDI chips do cost well below $10, and one can do 4K in single 3G as well...
16:16
Bertl
can you link to a 6G SDI chip for 10 USD please?
16:18
danieel
probably not due to an NDA
16:18
Bertl
I guess it is obvious, that we won't use chips which require NDAs
16:19
Bertl
but anyway, any hint for a 6G or 3G SDI chip within a reasonable margin?
16:19
Bertl
best I found so far is the LMH0340 which costs about 50 USD
16:20
Bertl
(note that one can do 3G but not 6G)
16:21
danieel
there is no encoder chip, so you would need to make it in FPGA
16:21
Bertl
ah, okay, so you are talking about a 6G fpga solution then, yes?
16:21
danieel
if you go to 12G sdi, then there is a chip which takes 4x 3G
16:21
Bertl
what FPGA do you use for 10 USD to do that?
16:22
danieel
you have the zynq there.. it has not transceivers?
16:22
danieel
*no
16:22
Bertl
it costs slightly more than 10 USD :)
16:22
Bertl
and no 7010/7020 do not have high speed tranceivers
16:23
danieel
then that should be the reason of not doing sdi
16:23
Bertl
so you are now from
16:23
Bertl
"6G SDI chips do cost well below $10" to don't do SDI :)
16:24
danieel
i am not saying you should not do it.. you cant because of the constraints of the platform
16:24
danieel
you can easily say you can do hdmi 2
16:24
danieel
(4k/60 at 4:2:0)
16:25
danieel
but you would need the $10k hdmi specs
16:25
Bertl
it's a pleasure to chat with you about technical details :)
16:26
danieel
you have no transceivers, so forget about SDI
16:26
danieel
but do not blame it on $50 cost
16:32
Bertl
fact is, one 3G SDI output costs us about 50 USD, if you have a cheaper solution, please step forward, otherwise accept it as fact
16:36
danieel
if you use the fpga which you use...
16:36
Bertl
yes, we use the FPGA we use, what a surprise!?
16:36
danieel
get a fpga, without arm and you have the sdi for free
16:37
danieel
you use an arm processor with a tiny ondie fpga
16:41
Bertl
well, at least we know what we use :)

i dont see any buttons or anything

please don't post unreleased articles to this publicly logged IRC channel
17:42
danieel
voting is unnecessary, the result is already known
17:43
aombk
sorry
17:44
aombk
danieel: what is the result?
17:45
danieel
the middle one
17:48
aombk
do you like this result?
17:49
danieel
i have my own camera designed upon that sensor, which is already capable of 4k recoding
17:50
aombk
nice. what camera is that?
17:58
danieel
prototype/experimental
