hi all!

how hard would it be to do a silent mode sequence like 4K at 30fps ala go pro burst mode?

there is definitively a market for that out there !

we already have a fully functional 64 x eos 600d bullet time rig, and are currently building a bullet time rig with 64 hero3+ and there would be a couple of function we wouldn't mind give decent amount of cash for :

1) exposure lock or even exposure control....
2) shot confirmation signal as soon as shot is taken
3) access to the network side of the linux system to be able to download the pics from the card to a computer via any of those : WIFI/USB/ETHERNET.
4) fix IP adressing

Hi guys!

so .... after playing a bit with the sony FS_700, i have to admit that slo mo is cool !

what are the chance to have a mode to record on the buffer at higher speed rate such as 120fps or 200fps until it is full and then move the file to the card ?

I wouldn't mind having a 1080P120 or p200 even if it is only for 2-3 second ... that would really break the barrier...

hi guys !
as promised i had the chance to play a little bit with the 1Dc  : one word  : whow!!!!

4K is the way to go.... even downsized in 1080P24 there is more detail than i ever manage to get on my 5DMKIII.
high iso performance is just stupid... a little edit I have done in 1 hour alone in Paris : https://vimeo.com/58056838
Video framegrab of this thing are just ridiculous....

enough said about this beast and back to reality = ANY twin digic 5 can apparently do MJPEG at 100Mb/s (and event way higher than that) the bottleneck is the card and not the camera... so the 1Dx is capable of that but the 1Dc digit are "overclocked" in order to achieve 4K Mjpeg compression on the fly and therefore there is a better cooling.... sensor is not heating more in 4K... (sensor is on or off but wont heat because of image size)
why Mjpeg? because MJpeg is just a JPEG image sequence in a quicktime container and therefore there is no image size limit where H264 do not support 4K yet.... ;D
so basically the 5D MKIII is definitively capable to record 4K Mjpeg but at which frame rate? ( I wouldn't mind a 12fps 4K ala go pro for special effect) and also it is possible to over clock the Digic V .... but it heat more

Share Your Videos / 1Dc in 4K

hi ! there here is a quick preview edit that I have done with a 1Dc, nothing spectacular or no ML here, because I only had it for 1 hour but the camera is crazy and 4K does bring a lot when it comes to detail rendition, i hope you will enjoy it :

that is wher the 1Dc firmware should come handy  ;)

according to a very reliable contact @ canon, I was wrong : the only Hardware difference from a 1Dc and  a 1Dx is the sync pc port (for the flash).
there is no extra hardware for cooling or so...
It is a firmware limitation to go around the 30mn limit to a camera not to be taxed as a "video equipment" in europe (and surely also a way to make a good extra margin on top of an otherwise stock 1Dx) so it means a very good thing to us :
1 DIGIC V can handle 2K or 1080P50 if 2 DIGIC V can handle 4K. but even more = IT IS CAPABLE OF DOING CLEAN FULL HD THRU HDMI JUST LIKE A D800.... sometime I'm wondering what is wrong with those people who are limiting there own stuff on purpose.....

more voltage = more heat...
the 1Dc and the 1DX are indeed different on a hardware basis. I've alredy played with pre-prod sample and i can tell you that there is some minor tweak on the 1DC (for example the flash synchronization PC port has been replaced by a stéréo headphone jack) also the same battery last at least 20% less time on the 1DC.
sorry for my low software knowledge...
next week I will have my hands on a 1DX and a 1DC for a couple of hour, how can i get the firmware out from them without briking the camera?
would that help you guys?

the 1DX and the 1Dc run on twin Digic 5+ and only the 1Dc can do 4K MJPEG or 1080P60, I guess the real challenge is to get the firmware of the 1Dc and to see what is the difference ... they have reworked the 1Dc for massive heat dissipation, witch lead me to think that maybe they also run the processor at a higher clock speed.

I can have my hand on a 1Dc quite easily so if you explain me how to do a backup of the firmware I can try to send it to you... to see what are the difference that allow such cool things !!!

here they say that only one processor do the writing to both card :
http://thenewcamera.com/?p=8403

I dont know how accurate the schema is but, if it is correct, ONE digic 5 can handle TWO different card at full CF speed (2X150Mb/s) so technically the processor on the 5D MKIII writting data at 150 Mb/s on a UDMA 7 CF card is only doing 50% off it's ability. (after all a 5D MKIII can write on TWO separate card with ONE digic5+)

I am pretty confidant that the 5DMKIII can do 720P120, 1080P60 and 2K.P25. the matter is not what the camera can do but what the camera can write... Doing 422 MJPEG is way less intensive on processor power than H264 would be, but is doing heavier file.

Outputting 150 Mb/s for a long period will get the camera very hot quite fast.... but for small run it might not be an issue... and the one that need to record longer clip have the money to buy a 1Dc.

my main concern would be to get 1080P60 and 720P120 as it would just help me so much in action sport.
Event if 150 Mb/s is Si-Fi and 110-120 Mb/s is more like what real world fig gives you... that gives enough bandwidth to get good 1080P60

I definitively agree that ML should be on a small write-locked SD and the recorded video should go on CF.

just for fun and for those who like Time-lapse here is a Time-lapse of 140 000 tilt and shift stills that I have done for Disney with my colleague Daniel Meyer :

I would love to get those time-lapse bulb-ramp fonction on the 5DMKIII.

Queep going : you guys rule !
