I may or may not have just found the BEST sensor.
04:02
Spirit532
A company replied with the pricing, this could actually make a really, really popular camera.
04:02
Spirit532
$600 for a 4MP(2300x1700) sensor that can do 500fps at full resolution.
04:03
Spirit532
And $300 for a 1280x1024 sensor that can do 1000fps at full resolution and up to 1Mfps at lower res.
04:04
Spirit532
Going to ask them about NDAs.
04:06
Spirit532
And that's in one-off.
04:06
Spirit532
It's $225 in 1k order
04:08
Spirit532
Holy hell, that's 16 gigabits of data
04:14
Spirit532
If this doesn't have an NDA, we can forget the CMV2000 altogether, lol
04:25
Spirit532
Oh, noooooo....
04:26
Spirit532
The Grade-1 microzed is only capable of 950Mbps of DDR data per lane
04:26
Spirit532
not enough for the full 1080
04:26

morning folks!
05:24
Bertl
Spirit532: what (sensel) size does the sensor have?
05:24
Spirit532
the 4MP one is 4/3"
05:24
Spirit532
the 1.3MP one is 2/3"
05:25
Spirit532
but the microzed is the bottleneck here, sadly
05:25
Spirit532
since they both have 16 LVDS channels running at 1080MHz each
05:25
Spirit532
the 1.3MP one has a 12b ADC, the 4MP one is 10b
05:26

I'm waiting for a reply on the NDA
05:27
Spirit532
but either way 1000fps @ 1280x1024 is the same as my real high speed camera(NAC Memrecam fx K5)
05:27
Spirit532
Which is quite awesome
05:28
Spirit532
I can PM you the links
05:28
Spirit532
I'm just not sure if I should get people's hopes up by sharing it publicly
05:32

well, doesn't help for cinema applications if it is a small size sensor
05:35
Spirit532
2/3" is okay
05:35
Spirit532
but the 4MP one is 4/3", and plenty of things have been shot on MFT
05:36
Spirit532
there's at least the GH4
05:39

hte APS-C (1.8") sensor (CMV12k) is already considered 'small' by cinema people, i.e. they are often asking for full frame sensors
05:41
Spirit532
hey, I'm not a magician
05:41
Spirit532
I can only google
05:41
Bertl
*1.18"
05:41
Spirit532
if I had the money I'd design a 35mm 8K 1kfps sensor
05:42
Spirit532
but that's like $50k in R&D and 30 people
05:42
Bertl
just saying, because you advertized it as the perfect solution :)
05:43
Bertl
but if sensor specs are available without NDA, then it might be good alternative nevertheless
05:43
Bertl
(alternative as in option for the Beta)
05:43
Spirit532
the beta isn't fast enough :s
05:43
Spirit532
just a few MHz not fast enough
05:44
Bertl
you are aware that we output 1080p60 on all Betas, on two to three HDMI ports, yes?
05:44
Spirit532
I'm aware of what the specs tell me.
05:44
Spirit532
The LVDS lanes on the microzed are not capable of doing 1080MHz
05:44
Spirit532
Only 950.
05:44
Bertl
well, the specs and the reality differ here
05:45
Spirit532
Have you pushed it that far?
05:45
Bertl
we are using 148.5MHz pixel clock, so they are running at 1.485GHz
05:45
Spirit532
okay
05:45
Spirit532
well, then there's the problem of RAM
05:45
Bertl
1GB
05:45
Spirit532
not enough.
05:46
Bertl
depends on the application
05:46
Spirit532
well, if you want to use the sensor to it's fullest
05:46
Spirit532
it either has to output to something REALLY expensive
05:46
Spirit532
or have an enormous amount of RAM
05:46
Bertl
but I'm looking forward to your solution :)
05:47
Spirit532
I'm not sure what to do yet myself
05:48
Spirit532
this is way too fast for me to imagine a cheap solution
05:48
Spirit532
it either needs an absurd amount of RAM on a separate board, or a module routed
05:50
Spirit532
I'm not aware of any recorders capable of even HD @ 1kfps
05:52
Spirit532
This is weird, the sensor is TOO good.

BAE/Fairchild: MST4625 APS-C, 4608x2592 @ 240fps, global or rolling shutter, 22bit 84dB dynamic range, 5.5um
07:05
pusle
not sure if it's out yet
07:05
Spirit532
I just read the datasheet for the 4MP sensor
07:05
Spirit532
it states IN THE DATASHEET that you can overclock the sensor
07:05
Spirit532
2k x 1080 @ 1kfps
07:10
Spirit532
pusle, it'll probably be heavily NDA and very expensive
07:10
Spirit532
not much use for apertus
07:13
pusle
perhaps, but it's probably the most low noise 4k sensor in APS-C you can get
07:14
Spirit532
yes
07:14
pusle
I know they have done deals with blackmagic previously. Their bare chip cost shouldn't be much different from cmosis
07:38
Spirit532
I just looked at the datasheet again
07:38
Spirit532
the 4MP sensor isnt' LVDS. It's 16x10 parallel.
07:38
Spirit532
Well that makes it impossible to use with the microzed or the beta/gamma

uhm..
07:43
Spirit532
yeah
07:44
Spirit532
the same sensor
07:47
pusle
and looks like Blackmagic has some exclusivity for video applications :x
07:48
