confused --> SLR HD vs XHA1
Sorry for my ignorance but...one of my customers discovered this
Canon EOS 5D Mark II Digital SLR Camera - Canon UK for me today and I was wondering...if this SLR can shoot full hd/progressive, it has interchangeable lenses, etc...what makes it worse than my XHA1? Which are the technical differences in between these two monsters? thanks! |

XHA1 is fully designed for video production, Zoom lens thats x20, try that with a DSLR and the lens will be huge, has all the inputs/outputs required and assist, the design of the camera for hand held, try shooting hand held with an SLR camera that's smooth and make changes whilst shooting, and lastly the rolling shutter effect from the CMOS sensor.
You could shoot a short film with the 5D because ever shot would be really well controlled and have a camera assistant etc..undoubtedly the DOF, range of lenses available (cost would be endless though) and the image you get on it is awesome. But if you want a camera for video production purposes where its shot real time like a doco,wedding, event...etc. I wouldn't recommend the 5D because it would be quiet difficult to shoot with. |

I haven't looked at the Canon 5D but I imagine it is very similar to the Nikon D90 when it comes to video.
So here are a couple of things I found for why an A1 is leaps and bounds better than a DSLR when it comes to video. This is a D90 review from Ken Rockewell's website. I Cut out some irrelevant stuff: "There is no autofocus, so God forbid if anything moves (the whole point of a movie), because focus won't track. Since D90 can't autofocus while shooting movies, they suck. If you're going to try to film anything that moves, the entire point of a movie, forget it. The "Live View" isn't! The images on the rear LCD, just like every digital camera's LCD, is delayed a fraction of a second. It will be very difficult to track and predict motion and action, since what you're seeing on the LCD already is history by the time you see it. There is NO live finder, like a real SLR viewing on ground glass. Nikon's USA User's Guide, page 51, warns movies will have nasty tilts, banding, bends, and distortion if anything moves horizontally or if you pan. Even if nothing moves, the manual warns objects can have jagged edges, false colors, moiré and bright spots appearing before your eyes. The D90's movies can't do stereo and can't do smooth power zooms either. If you can get focus, you still can't set exposure. Exposure seems to run off on its own. In dim light the D90 applies hellaicious amounts of noise reduction to the additional ISO it piles on. Another gotcha is that I see no mention of how long your shot can be, but other Nikons with Live View (the same technology used for movies) warn that you can't do it for more than a few minutes at a time before the sensor overheats. The sound on the D90 appears to be mono only. Image quality is limited by the data compression in 720p. Al the textures are lost even though edges stay sharp. IN hollywood, we refer to this making your video "look like cartoons," which also have sharp edges but no textures." This is from Phillip Bloom's Website, also edited: "You can’t manually control the exposure (you can lock exposure by pressing the AE lock button once assigned to “hold” in the camera settings, something i didn’t know when shooting this). But the focus is manual only. No external mic input but there is a very low quality microphone built in. You can also only shoot in 24p mode. Not a bad thing, but 25p and 30p too would have been great! I was pretty impressed for what it was, putting my 35mm lenses straight onto the body and getting shallow DOF without using adaptors is great, but I think we are a couple of years away before we see a camera like this with enough video features essential to any cameraman. Pros: Great image considering the limiations, 35mm DOF, price. Superb DSLR. Cons: Rolling shutter is awful, as bad as it gets, no external mic input, only 720p, 5 minutes clip max implemented to prevent sensor from overheating." |

"Rather than thinking of [Nikon's] D-Movie as an adjunct to the still photographic features of the D90, realize that it is a feature tacked onto Live View. Live View chooses a CMOS shutter speed and ISO to allow for a reasonable preview image for the still photographer's picture, rather than using the ISO, mechanical shutter speed, and aperture that are set chosen for the actual making of the still image. D-Movie is a quick and simple way to record that stream of info from Live View." Canon's 5D2 appears to have been designed along this same conceptual line: its video function is an adjunct with almost none of the manual controls we expect from a camera dedicated to shooting video. That may or may not make a difference to you, depending on what you need to shoot. Specifically, the shutter speed and ISO settings on the dSLRs' video modes are not always (& in some cases never) manually controllable. Canon's XHA1, like other high-end video cameras, allows full manual control over nearly all aspects of the image. It also features professional audio I/O. Why all the excitement, then, about the dSLRs? Mainly because of two things: 1. The dSLRs' relatively enormous sensors 2. The ready availability of high-end interchangeable lenses for the dSLRS The implications to the craft of videography—especially fiction filmmaking—of the dSLRs are potentially so momentous that a lot of shooters are seriously considering adding one of the dSLRs to their toolkits, or even selling their current video rigs and retooling around the dSLR form. I for one may be willing to work around "partial" manual image control in return for the benefits of the dSLRs: 1. Far greater & subtler light-sensitivity of the dSLR's sensors 2. Their sensors' much-increased rendition of detail 3. Their ready facility with a constellation of interchangeable lenses 4. Their attractively shallow depth-of-field and bokeh effects Just keep in mind that the video-enabled dSLRs are first-generation machines. As such, there are distinct trade-offs in choosing one camera style over another. Only your shooting needs will tell you whether you should choose one, the other—or both. |
I'm not nearly as pessimistic about the EOS 5d Mark II as others. To be sure there will be enormous ergonomic challenges trying to shoot video on it, not to mention audio will not be easy either. Image control and focus will be challenging. And it won't be ideal for all situations.
The bottom line, though, is if this thing makes your end product better, who cares about all that other stuff? I have a Sony V1 and believe me there are enormous inconveniences including - questionable image quality, terrible low light performance, noisy image, no depth of field, unreliable tape captures, etc. My feeling is I can deal with the issues on the 5d just as easily and end up with a better product. It's hard to know how it will actually perform in the real world. But, to me there is not much risk in getting one of these to try it out. Worst case, I have a kick ass still camera. The best hope is that this camera shakes up the video camera industry which, quite frankly hasn't distinguished itself lately. Sony seems intent on releasing the same camera with different names every few months rather than actually improving them. Panasonic can't give up on the P2. Interesting times. |
In a meeting yesterday, we had a similar discussion with my NASA contractor client who has two XHA1's. We came to the conclusion that they are completely different and can be used for separate applications. The XHA1's will continue to be used for run and gun documentary/documentation. The decision was made to buy the 5D as a high res still camera for shooting stills for animation modeling, print, posters, and as a "b" camera for the XHA1's.
It will however be interesting to compare two when we get it next year. Cheers. |

Its specs says 12 min in HD Mode, due to 4GB (fat32) limit. This camera kicks ass. It puts XH-A1 to shame. True you loose all the manual control, but when you such a superb low light performance, its too good. It would be perfect for ceremony event (not too much movement) if I can get 30min HD. But for a party kind of environment inside a room, low light would have been fantastic, but the manual focus is throwing me off. |

No power zooms - again, less than ideal but not a deal breaker for me. Zoom should primarily be a compositional tool, but an occasional slow zoom is useful. Personally I find myself wishing I could do bang zooms (which the XHA1 can't) more often than I find myself using a smooth zoom in a shot anyway so in that respect the 5D could actually be considered better than the XHA1.

Laforet's film addresses the noise reduction issue - watch his behind the scenes video to see XHA1 footage back to back with the 5D under the same low light conditions. It's shocking how clean the 5D looks in comparison. Quote:

Clearly the 5D is not perfect as a pro video tool. I'd prefer to have full manual exposure & audio control, and various frame rate choices. I don't know if it will replace my XHA1 or simply augment it, but there are tradeoffs on both sides. I think the larger sensor, incredible low light capabilities, small size and lens choices may well outweigh the camera's weaknesses and make it a better choice for a lot of things than the XHA1... but I'm not planning to sell the XHA1 until I've had some time to put the 5D through it's paces. I wouldn't be entirely surprised to see a pro video camera with most of these features based on the same chip introduced at NAB. Of course, this is Canon we're talking about, so maybe I will be surprised. |

I bought a D90 and tried it out for video shooting. Here's a clip of the result.
Nikon D90 at Singapore Riverside on Vimeo The exposure lock works fine, but it is not easy to directly control the aperture. The manual focus is tough, because the liveview LCD panel is very difficult to focus with, especially outdoors. Liveview is time-limited by temperature. In Singapore on a sunny day, that time is only a matter of minutes and that's not just shooting time. Just being in liveview mode makes the camera overheat. You have to continually switch back to viewfinder for focus and framing while the camera cools, and then select liveview only when you want to shoot. If you have a long shot to make you are basically screwed with this camera. And the other showstopper is the quality of the codec. There are artifacts due to downsampling, and macroblocks due to the MJPEG encoding. Fine details like water ripples on the river takes me back to the good old days of VCD. I believe the Canon D5 MkII should be better because it's using a better codec, but I expect there will be other gotchas, and I'm not planning to be an early adopter for that one. Ended up selling the D90 after 6 days. Richard |

There are also strange effects on closeups. The result is smooth faces with small freckles around the eyes and in the corners of the lips - pretty much anywhere there are delicate shadows. One video that compared the HVX to the D90 had that result for both cameras, but the D90 was less subtle about it. I'm still interested to know how many lines of video are available over HDMI. The camera would still have limited control, downsampling artifacts and limited dynamic range, but at least the details would come through when scaled for the web or DVD. You didn't happen to check out the HDMI results on an HDTV did you? (Off topic... how was the recent Grand Prix for the city?) |
Quote:
I know codecs and encoding hardware have improved over the past decade, but hobbling what otherwise seems like a forward-thinking feature with a codec that wasn't even cutting-edge a decade ago indicates to me that video truly is an afterthought for nikon at this point. |
wow that was great info guys , thanks! I can discuss with my client now!
I would still choose the XH A1 mainly because of the ergonomics/manual capabilities and storage even though the DOF and the possibility of using different lenses is very very tempting indeed! on any case, it seems weird to me that we've reached the level when an DSLR can be compared to a proper video camera and that some people would actually choose to use them instead when making films. Where do you think the audiovisual industry is going to? will there be still cameras and video cameras in the future or will we see 'big monsters' that combine all-in-one? thanks |

The Singapore Grand Prix went very well, unless you are a Ferrari guy - their race was a disaster. :) Richard |
I think it's only valid to group the D90 with the 5DII when talking about features. Or rather lack of features and ergonomics in both cameras.
The 5DII has a high data rate - something between 35-40mbs. I don't remember the D90 rate, but the Canon is considerably more. But what truly sets the 5DII apart is the low light performance. Is there ANY, and I do me ANY, digital video that looks as good as the Canon in low light? I see a lot of noise/grain in network TV dramas and even feature films when there are actual night scenes. (As oppossed to 10 ft-c scenes that are lit to look like night). All this comes "free" with a mid-priced DSLR. So some great stuff, but its the video camera equivalent to a view camera. The future will bring real video cameras with this tech. These cameras probably require a whole new lens line and that's a big deal for Canon. |

I think the issue is that to make a 5D a "real" cinema camera will involve a lot of work. And I doubt Canon is interested in doing it. Canon is a big company that has to behave rationally.
It's like the difference between 35mm format SLR lenses and cine lenses. Image wise they are very close, sometimes SLR lenses even look better. But their ergonomics blow for movie work. You can get them rehoused, use a follow focus that regears them, but these are all workarounds of varying effectiveness. In the end, a real production doesn't mind spending the $ on Panavision lenses, Zeiss Primes or Cookes b/c that little bit of extra utility is in fact very valuable when placed in the right hands--and required to get a pro to work on the project. Also, the pro cine lens cost is a far-off decimal rounding error in the budget of major studio film. Back to the 5D. Look at all the crap Red has to deal with to make 4 or 2K camera actually work for filiming. It's not the general concept that's so difficult, it's the little details that become a RPITA when making a cinema product. There is no way that Canon will jump through all those hoops with the 5D or it future iterations. I don't even think you'll ever see 24P. They aren't going to make a digital cinema camera for $3.5K and they certainly aren't going to want to support such a product. What I'm sure you will see is bleed through into their video division. As much as Red is feeling the effects of the 5D, the real emarassment will be to Canon's camcorder designers if they don't come up with some kick-a new products. But making a DSLR for both pro still photograhy and pro digital cinema is losing proposition that Canon rightly won't touch, IMHO. |
You know I am gonna boycott canon if they don't do 24p. I will literally harass them on the phone. It's just frustrating that the perfect indies cinema camera is just right there barely out reach.

Maybe I missed the response, but is it true there is a significant delay on the LCD screen when filming on the 5d? That would make it very difficult to film anything with movement (i.e a bride walking down the isle). She could be off the screen and I wouldn't know it -- and HD is VERY unforgiving on the tv.
|
No it's not true at all.

There is so much wrong with that post I didn't even bother to comment. I can't speak for the Nikon, but I can speak for the 5DMk2. 1. The live view is fine. 2. There isn't a film camera in Hollywood with an autofocus, so that fall flat on it's face 3. The codec on the 5D/7D is generally up to the task. Certainly more robust than any camcorder less than $10k 4. Film cameras record ZERO sound. So what's that got to do with the DSLR in narrative filmmaking? 5. Recording time.. The 5D records about the same length of time as a standard reel of film. Don't see an issue there either. The HDSLRs (Canons) are poor choices for event video cameras. However, they make rather exceptional narrative cameras, especially for the price. |
I may be wrong, but one thing you can't do with a DSLR is a slow, perfectly smooth zoom from extreme wide to extreme telephoto.
|
We do weddings, and have two HMC150s and an HMC70. I'm excited to replace the HMC70 with a 7D or GH1. It will give us some variety (DOF), flexibility (the ability to hang it around my neck for roaming once I've locked in camera 2 on the alter), and the ability to get the wide angle family shots along with tight alter shots from far away (for Catholic weddings). It's going to be a valuable tool. I'm starting to lean toward the GH1 for its LCD.

Which full size sensor lens can zoom from extreme wide to super telephoto?
|
Well rather than vague terms like "extreme" and "super", put some numbers on the table, and let's see what's available.
Honestly, the more variance in the focal length, generally the poorer quality the image will be. Something like Tamron's or Canon's 28-300 would qualify in my book. That certainly trumps anything I ever used when shooting film. There's some 20-200s out there as well. If you're talking about a 14-400, then no, you're right. There isn't anything out there in FF35, Cinema, or anything else that I am aware of, so I don't generally consider things like that. |
Quote:
2. There are no DSLR lenses with motorized zooms. It's near impossible or very difficult to execute a long, perfectly smooth zoom manually. |
Quote:
Yep, as I've said dozens of times. DSLRs are very poor substitutes to replace dedicated video cameras for a great many reasons. However, they are an exceptionally good mirror for film cameras at inexpensive prices. Yep, if you need to record a 550mm zoom, the video camera is your best bet. And if you need to motor zoom while shooting, then a traditional video camera is the ticket. Neither of these things have an equivalent in film. |
But to augment a multi-cam setup, I think I would be smarter to go with a DSLR than an adapter on a compact camcorder primarily because of the sensor. I need something small, I don't need slow zooms, I don't need audio and I don't need long clips. So unless I'm missing something, I think a GH! is the right direction.

But if that works for you, the price is unbeatable. |
I just can't see filming video without a swivel LCD. I've heard about the codec. :o(
I guess if the codec is bad enough I'll exchange it with a 7D -- or perhaps Panasonic will update it via firmware, but I doubt it. |

F35 Viper SI-2K RED Genesis Dalsa D21 None of these video cameras have a swivel LCD. All have footage with Hollywood releases. Many have Oscars attributed to their footage. |
All of those cameras are shot using external monitors or excellent veiwfinders.

The GH1 would be a good C camera for you. I don't like the 24P over 60i, but all these cameras have tradeoffs, and in Vegas Pro using the footage is as simple as dropping it on the timeline.
