Anybody have any idea how to get digital video out of this baby live, so I can broadcast it? The lack of viewfinder in video mode i can live with, but not that it has no firewire output for live video.

Haven’t seen those problems on my camera yet, but I know that clean gradients is in general a problem for highly compressed video codecs like H264.

In my tests I got flickering when the shutter speed gets to short. In case you encounter flickering you may use ND filters in order to extend exposure time. That will eliminate the flicker.

QUESTION:
I found that my 5D performs super good in average situations, BUT certain gradient blue tones (for example: blue sky) gets really really heavy about 11×11 pixel big artifacts. It looks rather like a webcam image but not like the high bitrate h264 it is. Did any of you encounter this behavior?

I have samples for that “gradient blues” if anyone wants to see it.

I think it shows up when the cam gets a lot of light and the sensor produces a very clean image. As soon as the light gets very low and the sensor starts to produce some noise the big block artifacts disappear.

I have been shooting some indoors in Iceland and I have seen a lot of flickering.

Some HD footage here.

a couple of low res film clips up..
the web does not do them justice…
antiochus1 film went from a 3 gig source to 140mbs ..so the image breaks up…
the original footage is lovely..

Marcel said an interesting this about this flickering with indoor light in Europe. Does anybody noticed the same thing? Most of video examples shooted with the 5D were made outdoor or indoor but with natural light. What about with neon and standard indoor light?

Yeah, found the conversion to prores also clipped luma and chroma data, so not recommending doing this anymore.

I’ve posted a new walkthru tutorial to cut, color, and compress 5dmk11 footage here:

“IMHO, this simple transcode would eliminate the long-GOP strain on your NLE’s CPU as well as optimize the source footage for multi-format timelines in Final Cut Pro.”

Not necessary. And unless you use an uncompressed format, you’re unnecessarily recompressing your footage. And then you’ll likely be compressing it yet again for distribution.

Avoid lossy recompression whenever possible.

i test the camera today in italy, in a hotel, with indoor lights, and the image flicker all the time, the 30 fps is not compatible with the 50 herz european electricity.
http://users.telenet.be/worldstandards/electricity.htm#voltage
is for this reason the frame speed in europe is 25 fps
in europe only can use this camera outdoor with sun light, or controlled studio equipment.

hello guys..
i have just tested this camera in london a preproduction model..
i believe it is a little bit of a revolution..
the red company must be concerned..
the fact is this is canons first stab at this converging technology and already it is such an exciting piece of kit.
if the company in the future can do 25 and 24 speeds and proper manual f.stop..asa locks on the camera when in video mode then that would be earth shattering.
as it is we have a bit of a work around…
they have let the technology out of the bag now…nikon in the future will have to respond.
canon have a video broadcast division so have to be careful in not destroying different divisions within the company ..nikon do not and i hope they will react with something great.
images are looking clean at 3000 to 4000asa which if you are used to shooting 500asa motion picture film,is incredible..
30fps is not good…
but folks start emailing canon and tell them you need to be able choose and lock asa and f.stops…having the camera pick asa and doing an auto plus or minus really hinders the potency of this beast..

Wow, thanks for the awesome data! Cool to see your analysis of the GOP structure, very helpful. Have you considered converting the footage to Apple Intermediate Codec or Appl ProRes 422? IMHO, this simple transcode would eliminate the long-GOP strain on your NLE’s CPU as well as optimize the source footage for multi-format timelines in Final Cut Pro.

I’ve posted a quick video tutorial to perform this transcode using Final Cut Pro and Compressor:

Interessant test. Jeg driver med medisinsk foto og video, hovedsaklig for nett, og 5D MkII ser ut til å potensielt kunne erstatte endel av både foto- og videoutstyret mitt. Noen spørsmål:

1. Hva kan justeres manuelt i videomodus, og hva er låst til auto?
2. Har man noen kontroll med nivået på lydinngangen?
3. Kan man monitorere lyden (headsett/meter)?

Hi I was able to try a test unit of the 5d Mark2 locally here in the Philippines. I couldnt figure out manual exposure with it on video mode. Where you able to operate manually or were you stuck at auto exposure. Im talking about the video mode function. Thanks a lot
