hey rainer_vie_!

hi rainer
17:10
rainer_vie_
wanted to package my py program with pyinstaller, but it seems it has some problems with Qt
17:11
rainer_vie_
the new renders a re looking awesome by the way of the beta camera
17:14
rainer_vie_
will it be theoretical possible to make a H264 encoder and store it on the sd-cards on the microzed then?

rainer_vie_: thanks :)
18:48
se6astian
theoretically possible but not straight forward and not a target for us
18:49
rainer_vie_
ok... so the new small ninja recorder would be a good solution
18:50
rainer_vie_
btw have made a package for mac of the transcoder... could any one test it please?
18:52

19:12
Bertl
the microzed sd card will be 'kind of' reserved for the operating system and the firmware
19:12
Bertl
but there will be a dual micro SD PMOD board which can be used for storing arbitrary data
19:12
rainer_vie_
ah ok... thx bertl
19:12
Bertl
(limit will be roughly 20MB/s IIRC)
19:12
Bertl
h264/265 encoding would probably require partial FPGA support to make it real time capable, but as sebastian said, not something we plan to work on ATM
19:15
rainer_vie_
sure, thought later on, it would be nice to record onboard... 20MB/s is not much but would fit to a couple of codecs

rainer_vie_: my concept does include h264 up to 1080p60, but only as a proxy/preview file, not the main output
19:50
se6astian
joined the channel
19:51
rainer_vie_
oh great, to have proxies in addition to the raw files would be awesome
19:52
danieel
the other choice is mjpeg, which is little more suitable as proxy, so the h264 is actually a preview - which can be used for quick evaluation of the shots
19:53
rainer_vie_
so on the other hand it would really nice to get proxies which can directly used in the nle. something like dnxhd....
19:53
danieel
dnxhd is dead, i would go straight to prores, even that certification is hard to achieve
19:54
danieel
the technology is basically the same
19:55
rainer_vie_
yes, heard that it is now a little bit better to get it... but is prores also paid license only?
19:56
rainer_vie_
an open source cross plattform codec with the same spec would be nice
19:57
danieel
its all mjpeg basically, just extended in bit depth / not so agressive compression
19:58
rainer_vie_
ah ok... thought vc3 is a new thing
20:00
danieel
i am not aware of any app which uses vc3
20:00
danieel
i suppose it dates back to times when nobody believed in gbit speeds over copper
20:00
rainer_vie_
is dnxhd not vc3 ?
20:02
danieel
dnxhd is a codec, vc3 is that codec pushed over sdi/mxf
20:02
rainer_vie_
ah ok... thx for clearing up
20:02
danieel
you can push various codecs over sdi.. but its not anything widespread
20:10
troy_s
Kind of different target needs there no?
