  • 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 5D-MKII - There is NO SKEW (not much)

What Sony 28mp camera? Their new one is 24.6mp and cannot even do live view....

Graeme, do you know if the RED ONE is a true global shutter (like an industrial high end camera) or does it have a very quick rolling shutter (effect)?

For our applications a frozen moment in time is more important, but we can make use of more genralized data. We need high res still frames to capture 360 3d (for texture and geometry) but can use lower res dynamic to direct 3d movement for character rigging.

The DSMC would be perfect for our applications. In the mean time we work with less eficient hardware.

Cheers in advance,

Eric

ONE has (two) rolling shutter(s).

Works pretty neat, though

Thanks for the info gunleik.

Although the Red One's Mysterium sensor is shrouded in certain amount of secrecy, what is the closest thing to an industrial "white paper" on the Mysterium in terms of timmings and waveforms, for example as you mention a dual rolling shutter. Where is the best technical document on the RED ONE in terms of its image acquisition and potential temporal/spatial displacement charcateristics. We need to crunch the numbers on this one. Any ideas anyone?

Cheers,

I don't think a DSRL formfactor will serve any good for shooting professional news stuff out of your hands. Skew or not, it won't look great anyway.

100 % Agreed

I have questions too...
About color sample, compression...
Anyone could help:help:
Graeme??
 
People have asked for more precise technical details before from Red, but they were not answered. I believe your best bet is to simply rent or borrow a Red and do whatever specific tests you need. Skew in particular has been extensively tested already, if you search past Reduser posts.

Thanks for the advice will check it out.

Unfortunately we have to engineer a fair amount to carry out the tests we would need to determine the viability of our techniques with the Red One. However it is useful to know what the potential weaknesses/pitfalls in a system would be before we rent equipment so that we may effect a decent experimental design. It would be nice to have a few facts or figures to design our tests around but with a bit of digging around a decent initial set of parameters could perhaps be guessed at. Spatial integrity of the imagery is very important to our work.

Does the DALSA 4K system use a rolling shutter or global? (perhaps I should stop being lazy and check it out for myself!)


Raphavf, perhaps someone working with the RED RAW SDK would have a closer understanding of the color and compression questions you might have.
 
Thanks Eric and Jbeale.
Actually i bought one Red one, but I'm still waiting so far:bye2: :bye2: :bye2:

Cool (maybee you're out of here), but waht number RED and how long do you expect to wait?

(We haven't jumped on that bus just yet untill the wait times go down, so in the mean time we will need to rent.)

So put it on a shoulder mount, still much lighter than a RED.

The question isn't whether it will compete with REDONE, it doesn't - but how does it compete with the Panasonic HVX Sony HVR and Canon HV30 worlds?

Well, I was this close to buying a HV20/30 + Letus 35 Mini combo when this DSLR madness started. The timing has to be a sign from above. So, here is one confirmed case of the 5D MkII competing with Canon's DV-cams + 35mm DOF adapters.
 
Take a look at some shots with a little production value.

Impressive for there first try.
Now if they take a serious look at the XL they might actually put something together that would sell some units.
I know i'm getting one for the bag.

Look it's not a REDONE - there are situations where rolling shutter artifacts will be an issue, but a lot of times it won't be an issue and this proves you can make some pretty darn nice movies if you keep the limitations in mind.

To me the combination of 21MP still PLUS 1080P video from a camera I can easily take with me almost anywhere (I'm sorry, the RED just isn't a casual, take with you camera), is well worth $2699, since I have already invested in Canon lenses for my RED anyway. I like the idea of selling my Sony HDR-FX7 and my EOS40D for nearly that AND being able to use my extremely high quality Canon L lenses on my "prosumer-style" video camera the 5D (with 35mm DOF to boot). And it will only cost me a few hundred to switch after I sell those.

(Anybody want a 40D and or FX7 - very low hours? ... No. Oh well, that's what ebay is for. NOt selling my RED though.)

I admire your optimism. I am definitely buying the Canon 5D MII when its available mainly for stills and to see what it is capable of dynamically. However, frankly I think for most applications the amount of Jelly will be a bit too much to take. So for example, a very slow well set up pan of a landscape, might be nice. However a medium shot of two people just carrying on a conversation at the normal speeds which people generally “animate” themselves will (I reckon) have visible or odd rolling shutter artifacts. Similarly a close up on someone’s face while talking/delivering their dialogue will also probably reveal rolling shutter artifacts. If it doesn’t, then that would be truly awesome.

Perhaps after we both get a 5D MII (in a few months), we can compare notes as to what can or can’t be shot to produce “acceptable results”. [maybee for under water work the rolling shutter makes everything look even more aquatic!]

Cheers,

Eric

I don't see the Mark II getting jerked around that much so it's hard to judge if it's getting skewed.

Does it really matter? The Mark II is a DSLR, not really a video camera. Video is a nice added feature, but it's not a replacement for a good HD body and good glass. It looks like it will produce stuff well for the web on a tripod, not really for feature films. Thoughts? I'm buying one. The video isn't a deal breaker to me because I shoot stills. If RED does something cool next year, I'll probably buy one of those too. I'm not a hobbyist so spending a few grand on a camera body is typically worth it for me to take everything up a notch and a nice little write off.

Well, the glass available for EF mounts is pretty f'ing good.

To me, this camera might really be great for shooting landscapes and stock 1080p. The main problem is lack of RAW, in my opinion. If it's recording 4:2:0 color, that is a major step down from RAW, as well.
