  • 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 :)

5D II Zone Plate...

We have posted a Zone Plate somewhere (looks perfect)... we can post one tomorrow if you don't mind delaying the announcement a day or two...

Ha ha ha.. no no no please don't Jim, that piece of picture is nothing 'significant' comparing to the announcement (we all sure about this).

But how about 3 days after the announcement, you post the Scarlet zone plate :ph34r: hee hee hee...

It's nothing urgent if that affect any of your existing timeline, we rather have Scarlet out as soon as possible, so please stop playing your 5DII :usd:

Guys, I am counting down the 3rd of Dec, I guess Jim is not going to sleep again tonight (as usual). So take good care of your health :-) (and everyone here).

Yes, the Canon is not the best.....but it is better than HDV. Yes????

Depends on the camera, but I've never seen such a bad chart from even a really cheap HDV camera. Remember this is not so much the compression we're seeing, but what happens when you try to get video from a large sensor and don't do it properly.

The 5d is first a camera for photographer, and a fine versatile one with many adventage including impressive iso possibilities. Video is the cherry on the cake which will be good enough for non professional use and all of this for a very decent price...
End of story no?

Is it really worth writting more on the subject?
 
Thanks for that Tico, yes, quite visible.

Vincent, think of this as education on how cameras work. I think that here at RED we try to "do things properly", and it's often hard when people suggest various things we could do for me especially to say "it wouldn't look too good". I don't have the time to make up demo code to show what doing things sub-optimally would look like. Fortunately, in this case, it's done for me.

damn now you´ve got me all worried... should I get two batterypacks from RED or save the 500$ and settle for the 5D

it should be if the red guys weren't in panic.. :calm:
 
Panic? Hell no. We knew about the 5D2 and it's "1080p" way before it was released. I'm just personally shocked at how nasty it is on the zone plate. Pretty much all camera manufacturers use zone charts to help them develop cameras, fine tuning OLPF and image processing etc.

I think everyone was "assuming" that the video mode downsampled from the full sensor. It's pretty plain from these charts that that is not happening. Similarly, the low-ish skew is an artifact of the fact that skew looks less if you read out less lines!

The aliasing is strong and very apparent. To wit:

some unpleasant artifacts?.. yes

aliasing?.. check it w/ a different player and maybe you'll have a good surprise.. or maybe not..

it depends of your choice.. is 5dmk2 a scam?..
 
Real men can get good shots on any camera.....within reason. :)
 
Maybe not I'm afraid. Very visible in both Quicktime player and VLC.

Jim
Did you again forget to put a mark on "use high-quality video settings when available" in Quick time preferences :)

Albert
 
Bad news Albert, that the h.264 codec doesn't use that flag, (it's for DV mainly) and hence changing it doesn't make the decode look any nicer. VLC doesn't make it look any nicer. And why? Because it's a problem with how the data is read off the sensor....

does it have its flaws?.. sure it does.. bring it on for $2700.. old & new customers won't miss :greedy:

you are one of my heroes.. but so far.. among all you.. the accuracy has just been w/ this smart kid here:

You know I used 1D MK III for my photography? I have a bunch of Canon L glass in my cupboard. They make really great stills cameras. Jarred's post is fair and reasonable.

Graeme
 
yes.. but he didn't bash the obvious.. this camera is a milestone.. before we had you for.. now we have this camera for pushing you to give us 35mm under $3000.. this would be truly revolutionary..

a red1 customer speaking not in panic :calm:
 
Sure, but I'm an image processing geek, and view things from that perspective.

Graeme
 
I appreciate this info and all but it does feel a little odd to come from Jim. Is the Mark II really that much of a threat to RED? The big advantage it has right now is that it's a completed product you can order while Scarlet/DSMC are still in the development stages.

I've seen awesome looking footage on the Mark II shot by pros- awesome in the sense of good Canon optics, nice and shallow depth of field and decent low-light performance. Not so awesome is the 30p which looks too home-video to me, the low-ish bitrate and lack of a RAW option. All of which make me more interested in what RED has to offer. But I'm not going to obsess over charts like this as my deciding factor.

And in all honesty these cameras are affordable enough I hardly see the need to pick one over the other. I'm planning on getting my hands on both. There's no one camera to rule them all or whatever. Doesn't Jim himself have every camera ever made for this very reason- it's interesting to check them all out. All that said, I think anyone who's remotely well-informed can make the distinction for themselves without the need for this sort of nitpicking, but maybe it's just me.
