  • Hey all, just changed over the backend after 15 years I figured time to give it a bit of an update, its probably gonna be a bit weird for most of you and i am sure there is a few bugs to work out but it should kinda work the same as before... hopefully :)

Canon EOS 5D Mark II: 21MP and HD movies

Red47 said:
exactly right. a lot of people have been complaining about the video features on these D-slrs but the truth is the video feature is a BONUS. the cameras are marketed for photographers. the only really practical use for the video function on these cameras is photojournalism. in which case this feature is quite useful. it gives photojournalists the option to use video if needed without having to carry an extra camera. which btw is very useful because more than one camera can be heavy not to mention bulky to carry.

Agreed...

And not only photographers and journalist photographer, but also a pro or amateur i.e

I was taking some shots of my baby girl and she starting to speak her first words...

And i start to cry... my god dam 40D in my hand just give me some frames...what a shame:ranting2:

Thats why we all need this puppy DSMC ...please Jim:help: :w00t:

One last thing:
It's entirely possible that Canon will release a firmware update for 24P, as 30P seems to be a bit of a disappointment. If this happens, the camera will be more "complete" IMO, even though it's not meant to be a serious filmmaking tool.

Agreed. I'm going to wait eagerly for the release and see what is actually delivered. I'd hope they can build in 24P.. also some lower res high speed modes might be kinda cool.

Does anybody know if the low-light performance of the 5dII is the same for movies as it is for stills? That would be quite amazing.
 
Surely they could do 24p in a firmware update if enough people ask. I mean it's less frames captured per second, same basic concept. Ought to be a no-brainer. Data rate is very nice though and H.264 much more appreciated than the M-JPEG that the N90 uses. Let's see some samples. :)

What is this issue about auto ISO?

Can anyone please explain to me exactly how this camera records video? Does the mirror need to be up for LiveView? How is the full-frame image being downsampled inside the camera?

Is it possible to pull an uncompressed 1920x1080 feed off the HDMI port?

Saw that- it's a little like apples and oranges though. 1080p vs. 4k. Still interesting.

I second all of Tom's questions.
 
Jaime, why no Malick or Kurosawa in your avatar? :)

On preproduction units, it's not possible to set your ISO: the camera chooses whatever it wants. (You can reportedly "lock exposure" at least, so that it wont jump around on you.)

Even worse: you don't have control over the shutter speed.

Canon, Inc. R&D department can explain it, but no one else knows (or is willing to tell). It might be partially sampling the sensor, using a quick-and-dirty debayer, or any number of other nasty methods. I can tell you for sure it's not doing a max-quality sample, debayer, and resample.

(For the same reasons that RED ONE, at 20 times the price, doesn't do a max-quality sample, debayer, and 1080p resample, no matter how much we've asked for it: it's hard.)

Yes. They haven't perfected the art of seeing through mirrors yet. ;-)

Yes. I've already seen this demonstrated with the 5D mark 2. That will at least give you 4:2:2 8-bit uncompressed, a little better than 4:2:0 AVC.

Haha, smartass. But they could be feeding the low resolution signal to the "Liveview" in any number of ways without raising the mirror, couldn't they? The viewfinder on an SLR functions precisely because the mirror is lowered, obviously. I don't have a LiveVeiw camera, so I don't know how it works. Does LiveView just sit there with the mirror raised all the time? That would seem odd to me, but who knows.

Yes, in fact. :) They could use partially transparent mirrors (I forget the word), yet another prism, a second sensor, or a rangefinder-style separate system. But I think the most popular liveview implementation going forward will be mirror-up.
 
Can RED answer this?

I was reading Vincent's blog as well, this is rather quite surprising. I don't think anyone would knock Canon's sensor technology . . . compare a 12.8 MP still frame RAW from the 3 year old 5D to a still of RED. Canon's sensor is superior, but its not a film camera. I wouldn't expect to get a still from RED that blows away a top notch DSLR (and yes, the 5D produced sharper images than the 1dsMKIII, most 5D users didn't want the 5DMKII to be over 16MP because of the pixel density . . .12.8 was truly a sweet spot for the 5D. It still produces more detailed images than Nikon's D3 and D700).

Now most people at DPReview are complaining about the 21.1 MP soft, blotchy quality of the 5d MKII (but we haven't seen RAW's yet). All I'm asking is: Canon makes their own sensors and has been perfecting them for a while and produces a great still DSLR: can they not also apply this to film and give RED some competition? Obviously they haven't yet with their XL lines of cameras but I'm just wondering . . . and Vincent said some harsh words!
 
Canon has been asleep at the wheel for a decade when it comes to HD video cameras. They could have easily put out an awesome digital cinema camera by now with a top-caliber sensor and world-class glass. But for some reason, they are totally out to lunch when it comes to HD video. They just simply don't seem to care!

Most users don't know how to compare two cameras. Aliasing artifacts are not "sharpness". 100% crops is *NOT* a valid way to compare cameras because it emulates wildly varying output sizes (e.g. comparing a 4x6 to an 8x10). RAW converters use different noise reduction for different camera models.

The 1Ds mark 3 (and by extension, the 5D mark 2) easily beats the 5D in "sharpness", signal-to-noise, dynamic range, and low light performance.

If Canon can achieve the level of performance they do now for their sub-2-micron-pixel cameras, I think the sweet spot for me is around 100 megapixels. But I'll settle for 21 in the mean time.

If that's true after the 0.7 MP is equalized out, then it can only be because of a weaker anti-alias filter or someone did a comparison without using the same RAW conversion.

Canon has a competition problem in that a significant part of their video business, and I would guess a very profitable one, is selling lenses to Sony, Panasonic, JvC, Ikegami, with one major competitor, Fujinon, that would take all of that business if Canon were to make a truly competitive camera. So they won't do it until the profit they are sure they will make on the HD cameras will offset what they make on lenses.

I believe that is why Nikon was first out of the gate with HD video on a DSLR. Canon then responds because they can tell Sony, et al that "Hey Nikon brought it out so we have to compete.."

Nikon has no video lens business so will probably drive the improvement cycle for video on DSLR. I.E. Canon will always have whatever level of video capability they need sitting in a drawer - and will pull it out whenever they need to in order to stay one step ahead of Nikon.
 
HDMI 8-bit or 10-bit

HDMI 8-bit or 10-bit

Hi Daniel. Are you sure its 8-bit and not 10-bit. HDMI supports 10-bit 4:2:2 and even 4:4:4 though no one seems to be using it yet..
