Rajiv, you have to do what you have to do, but here in the USA, it is preferred to shoot with HD at all times no matter if the editing will be done in HD or SD. These days HD is just as easy to edit as SD and offers several advantages in post even if you are editing with an SD timeline. I highly encourage everyone to shoot with HD at all times, plus as I said, when the camera is in an SD mode, some of the functions are disabled. When it's done properly, down-convtered HD to SD looks better than if it was shot SD in the first place. This is the same reason a lot of high-end productions now shoot in 4K and downconvert to HD. Plus having the raw footage archived as HD clips future-proofs the footage in case it is needed again someday. I have not shot anything in SD since early 2006. But each person needs to come to their own conclusions.

BTW, I never shot on VHS even if my program was going to be distributed on VHS. :-)

Yes. All Sony camcorders that have a fixed lens are parfocal.

Re: Sony PMW-200 Brings HD 4:2:2 Workflow to XDCAM Camcorder Line
 
In working with the PMW-200, I have discovered an irritation that I haven't seen mentioned here. When using the handle zoom rocker (not the main rocker on the camera body), the zoom continues for about a half second after you release the switch. This occurs regardless of whether you are zooming in or out. For me, this makes the handle zoom relatively unusable. This should be corrected in the next model. Also, the record button on the main body of the camera is extremely stiff. Even on a tripod, its difficult not to move the camera forward when pushing this button. Fortunately, the record button on the handle is easy to use. This should also be corrected by Sony in the future.

PMW-200 Focus issue part 2 mskogstrom photography

Re: Sony PMW-200 Brings HD 4:2:2 Workflow to XDCAM Camcorder Line
 
I wasn't aware of that article until you posted it, so I thought I'd get my camera out and really check it even though I've had my PMW-200 for about two months and have not noticed any problems.
I set it up on a Fujinon test chart against a contrete wall that has a lot of small texture to it. I fed the video output to a very sharp PVM-1741 OLED monitor.

The conclusion: No problems at all through the whole range of the zoom. Focus holds just fine. Sounds like maybe the guy who wrote the article should have the camera's back focus checked.

Mark,

It sounds like you don't have the right menu setting for the zoom switch on the handle. Go to CAMERA SET > ZOOM TRANSITION and change it from "soft" to "linear". Linear is the factory-default so somebody must have changed it at some point. Linear will stop when you let go of the button, and soft continues on a little bit as the camera tries to avoid coming to an abrupt stop.

I would suggest not using that switch anyway. The control on the handle is not a pressure-sensitive rocker like the zoom control on the grip and you're never going to get a decent looking zoom from it. It is just a simple on/off switch, with no pressure sensitivity, and no finesse. That's why the handle has a "soft" menu setting to sort of give it some ramping. But it never looks good. Use the grip instead.

As for the record button on the grip, that is purposely designed to be stiff and it couldn't be changed in a firmware update even if Sony wanted to -- nor would most people want them to. That switch is really intended to be used for handheld shooting and if the button was too soft or too easily pressed, that would become a big problem when the camera is being held by the grip I is better to have a nice tight button that won't get accidentally pressed.

If you want a record button that is easier to press and reach, why not program assign button 5 for record? It's in a much better position for tripod shooting than trying to reach around to the other side of the camera. Just a suggestion.

Re: Sony PMW-200 Brings HD 4:2:2 Workflow to XDCAM Camcorder Line
 
The EX1/EX3's back-focus can be upset by rough handling, bumps or knocks, I expect the PMW-200 is no different and that might explain the focus issues noted in the link. After shipping from japan who knows what the cameras been through. As Doug says all that needs to be done I suspect is to run the back focus routine. The only problem is how to get into the service menu?

Mark Donnell October 14th, 2012 01:33 PM

Re: Sony PMW-200 Brings HD 4:2:2 Workflow to XDCAM Camcorder Line
 
Thanks for the great suggestions, Doug ! I never would have thought to look for a menu item for that handle rocker adjustment. I believe that I might use the handle rocker for fine adjustments to the zoom where it would otherwise be hard to get the right initial pressure on the body rocker. The idea for button 5 also sounds great - I didn't know that the buttons could be programmed for record. Thanks again !

Doug, in your for-hire shooting, what percentage of the shots will be done with the PMW-200?

Doug Jensen October 14th, 2012 05:37 PM

Re: Sony PMW-200 Brings HD 4:2:2 Workflow to XDCAM Camcorder Line
 
Galen, I have no idea, but it won't be my primary camera because I own so many other cameras. The F800 and F3 are still my go-to cameras for different types of situations. The PMW-200 is a great little run & gun backpack kind of camera -- but still perfectly capable of replacing the F800 or F3 at anytime without sacrificing quality.

If I could only keep one camera, it'd be the F800 -- but I've got about $65K wrapped up in that camera. If I could only have one camera under $20K it'd be the PMW-200 or an EX3. It would not be the F3 or any of my other cameras.

Re: Sony PMW-200 Brings HD 4:2:2 Workflow to XDCAM Camcorder Line
 
BEWILDERED. Having read this entire thread (a lot of it over my head) I think I just need someone to simply tell me what to buy - PMW 200 or XF300. Needs: Portability for ENG style documentary work. Want the most filmic look and good low light. Not a production company, just a keen amateur and both could fit the budget (although not keen on the Sony media outlay). Thank you.

John M. Kim February 25th, 2013 07:08 AM

Re: Sony PMW-200 Brings HD 4:2:2 Workflow to XDCAM Camcorder Line
 
Terence,

Since you asked for the Draconian response, here's my answer:

Buy the Sony PMW-200.

-- Because of the relatively larger sensor, it is easier to achieve a more "filmic" look and it is slightly better in low light.

-- As an ENG shooter, you will appreciate the controls of the PMW-200 more. Neither have fully mechanical controls, but the PMW-200 "breathes" less overall, and there is less perceived delay when using the zoom and iris. The hard stops on the controls of the PMW-200 are also better.

-- Sony stands by the SxS Pro cards. It's unlikely that you'll suffer lost footage, but if you do, Sony will step in to try to recover it. You get what you pay for.

-- I found that for handheld shooting the XF300 is terribly front heavy. The PMW-200, with a large battery pack, can be used in a pinch pressed against your right shoulder, and although it's no substitute for a shoulder mounted camera, it just feels better on the wrist than the XF300. Try them both out and see if you agree.

Both are good cameras and you'll find merits in each, but IMHO the advantage goes to Sony.

I'm located in New York and know of several colleagues who are in production with long lead documentaries. A few of them are using the PMW-200. I don't know of any that chose the XF300.

Glen Vandermolen February 25th, 2013 07:39 AM

Re: Sony PMW-200 Brings HD 4:2:2 Workflow to XDCAM Camcorder Line
 
John Kim, that is excellent advice.

The one thing the XF300/305 had over the EX1/3 cams was the XF codec. Now that the PMW200 has a similar codec, the advantage must go to the larger chip 200. The EX line already produces great images. Adding a true broadcast codec can only make the 200 even better.

Al Bergstein February 25th, 2013 09:52 AM

Re: Sony PMW-200 Brings HD 4:2:2 Workflow to XDCAM Camcorder Line
 
As an xf305 owner who stumbled on this thread, and since you asked, I would tend to agree that if I had to buy over, I'd take a very serious look now at what Sony has to offer in this camera. Some additional thoughts for you to consider, especially if you can't rent them both for a week. Thoughts inline.

Al says: That is likely true. The xf305 is harder to give the 'filmic' look to. However, recently on Vimeo an Italian filmmaker put up a wonderful short that is as close to a HDSLR look I've seen. He did a very nice job.
For a three minute look, this is worth a peek to see that often the camera in the hands of someone who knows it can do more than most might think. https://vimeo.com/32406825

-- As an ENG shooter, you will appreciate the controls of the PMW-200 more. Neither have fully mechanical controls, but the PMW-200 "breathes" less overall, and there is less perceived delay when using the zoom and iris. The hard stops on the controls of the PMW-200 are also better.

Al says: I agree there is a slight delay on the 300 zoom, but I really like it's crawl. I also reprogram the handle zoom to be fast, and the grip zoom to be only slow. If the Sony can do that, I would alter it, as I find sometimes I want to get in quick, but don't want to have the opportunity of doing it accidentally (G). And yes, the hard stops on the Sony seem to be better than the 300's though it is a slight advantage.

Al says: I do like that they have 4 channels of audio available. This can help a one man band eliminate carrying a field mixer for larger interviews.

-- Sony stands by the SxS Pro cards. It's unlikely that you'll suffer lost footage, but if you do, Sony will step in to try to recover it. You get what you pay for.

Al says: I've yet to have a Sandisk CF card fail on me in over two years of shooting, either on the 300 or my 5D's. I cannot say that about SD cards. Even the best tend to fail, having used a T2i for a few years. But the SxS are known entities that have a global company standing behind, and that could help in a pinch somewhere hard to reach. Then again, carrying 10 of them is quite a bit more expensive I would think than the CF cards. And I can easily buy CF cards on the road, most cities have a pro camera shop that has them. For me, that mattered.

-- I found that for handheld shooting the XF300 is terribly front heavy. The PMW-200, with a large battery pack, can be used in a pinch pressed against your right shoulder, and although it's no substitute for a shoulder mounted camera, it just feels better on the wrist than the XF300. Try them both out and see if you agree.

Al says: While I tend to agree that it is a bit front heavy, I can easily rest the xf305 on my shoulder for long minutes,and using the IS helps a great deal, but I agree that likely both cameras should be on a shoulder mount attachment for long shooting. I have a device that allows me to attach my external battery back to the back of the mount. So it is 'fixable' on both cameras. But still neither appears to be a 'shoulder mount'.

Both are good cameras and you'll find merits in each, but IMHO the advantage goes to Sony.

I'm located in New York and know of several colleagues who are in production with long lead documentaries. A few of them are using the PMW-200. I don't know of any that chose the XF300.

Al says: Yes, the traditional doc shooters I've run into very much prefer Sony. Canon has just not really worked that field well, and so many pro shooters have been using Sony in industrial and broadcast. More attachments and cameras exist in rental pools for Sony. A much wider range of people trained in it. So again, if you are really working in the field, traveling a lot, needing to rent a 2nd camera or hire a second shooter, I would agree and go with Sony. If you are shooting on your own, won't be doing all those other types of shooting, the xf305 is a wonderful camera, and is worth a look.

Al you forgot to mention the wonderful display of yellow streaks on the XF300/305 viewfinder, especially once the sun has had a few split seconds to do its work.

Cameras are generally a matter of personal preference, both the Sony and Canon have their faults, as does most equipment but you find a workaround for most sooner or later.

"put up a wonderful short that is as close to a HDSLR look I've seen. He did a very nice job."

This must be a first on this forum, and I always thought the HDSLR was the runner up for video work.

Oh, and by the way, the close up and film look were created with the Redrock M3 lens adapter with Nikon lenses fitted to his XF300.

Thanks everyone for your thoughtful responses to my (admittedly) somewhat boneheaded question. I do welcome the clarification. I was leaning towards the Sony, but I think on balance that has it clinched.

Re: Sony PMW-200 Brings HD 4:2:2 Workflow to XDCAM Camcorder Line
 
Not sure what you want to video or where, but have you considered a totally different approach like a Sony HXR-NX30, a Sony VG30 and a Ninja 2 ? You could get all these different cameras for different uses and still have almost $1500 left compared to the PMW-200, Ottawa prices. True, you would not have the fine picture profile control of the PMW 200 but the NX30 has fantastic image stabilizer for hand held shooting, the VG30 has the shallow depth of field and interchangeable lenses for the film look etc and with the Ninja 2 both can record to high quality codec over HDMI and to relatively low cost hard drives. They can also both shoot 1920x1080P60 to AVCHD 2.0 as well as the North American frame rates the PMW-200 shoots at ( VG30 does not shoot 1280x720P60 I think but NX30 does with full time code including out of the HDMI). You could pack them all in a backpack too.

Re: Sony PMW-200 Brings HD 4:2:2 Workflow to XDCAM Camcorder Line
 
Thanks Vince, I emailed Luca before your reply here , and he didn't mention the Redrock, unless you were pulling my leg....(G). I certainly wouldn't need a Redrock to get a close up like that. It's more the overall feel of the video, not a specific shot I was alluding to. Since it was on the XF forum, I thought I was seeing a C300 shot, not a xf300.

I haven't experienced the yellow streaks that some have encountered. I guess I wasn't diligent enough to put the VF in the sun over the last, I think year and a half of shooting. But even my Zacuto finder for my 5D has a label saying not to expose it to the sun. So I'm not tempted to try. And Sony has had warnings for decades apparently saying not to expose their VF to the sun.

As to "as close to an HDSLR look I've seen', the OP was talking about a 'filmic look' which I assume means shallow DOF and other traits we think of as "filmic". Maybe the right word is "theatrical". My work with any ENG camera has not been what I would consider "like film". It seems more "like ENG". Could be me, likely is.

I find cameras to be a tool, I'm not married to any one brand, as mentioned if I looked today for an ENG, knowing where I am at now, I'd likely seriously consider the 200. The 1/2 sensor very likely does outperform the xf300 in low light. The iPhone remote seems like a nice touch. 4 Channel audio as well. But the 300 has served me very well. I consider the best camera I've got in my toolkit.

HDSLR is not a 'runner up' but appropriate for certain types of jobs, as ENG is appropriate for others.

Anyway, I think we've all helped him make up his mind, and I think he'll likely be a happy camper.

Yes, on balance I'd also tend to go for the PMW200 out of the two, and main headline reason must be it's 1/2" chips over the 1/3" of the XF305. It gives it an inherent advantage in such respects as lowlight performance and depth of field issues.

As others have said, they both share the same codec, which has full acceptance for general broadcast work - and as Glen says, now the PMW200 has that codec it takes away the one headline advantage that the XF305 previously had over the EX1/3.

But you say "keen amateur" and "not keen on the Sony media outlay", in which case the 50Mbs full broadcast spec codec may not be of such importance to you anyway? In which case, bear in mind that in 35Mbs mode it's feasible to use standard SDHC cards in this camera via an adaptor - and the 35Mbs mode is still considered fully broadcast compliant for "journalism cameras" according to the EBU.

Re: Sony PMW-200 Brings HD 4:2:2 Workflow to XDCAM Camcorder Line
 
Terence,

XF300 vs. PMW-200 in low light:



Although, shooting in 720p gives more sensitivity to the XF300:



The XF300 is currently $4695 vs. $6299 for the PMW-200.
After you factor in cost of media, CF vs. SxS cards, I think the decision is easy.

I bought and returned the PMW-200 because the low-light wasn't really any better than the HMC-150 I was replacing. Also, the LCD on the Sony has to either stay closed or open, if you have a light or wireless receiver in the cold-shoe. I also didn't like all the open vents on the camera body.

Just some things to think about...

John M. Kim February 26th, 2013 03:41 PM

Re: Sony PMW-200 Brings HD 4:2:2 Workflow to XDCAM Camcorder Line
 
The cost of SxS Pro cards is certainly a bitter pill to swallow. Luckily I was able to find used 32GB cards on the auction site for ~ $325 each. Expensive, but much cheaper than new.

One other advantage of the PMW200: 24-bit audio.

The XDCAM HD codec of the PMW200 comes with 8 channels of audio, whereas the camera only records 4. It's a minor pain to always cut out 4 channels of audio (many ways to do this, it depends on your NLE).

The only true annoyance I find about the PMW200 is that the internal noise of the camera -- I think it's the stabilization engine or something else in the lens mechanism -- is audible in very quiet rooms, even when in 100% fully manual mode. Occasionally it'll get picked up in my recording, even through my external microphone. It's certainly louder than other cameras I've heard. It's easy to post-process and get rid of, but it's not enjoyable to have to do this at all.

You'll go around in circles listing the merits of each. You might not be fully able to come to a decision without using both.

Manfrotto MVR901ECEX and MVR901EPEX,
I ordered the 901EPEX and was told there was some delays (CVP UK) so I went for the ECEX instead. I have not received it yet, however I've been able to put my hands on them (at the BVE London 2013) and the feeling is quite similar. They seem ok but not "heavy duty", I prefer a lil bit the EPEX, a bit thicker and maybe easier to control. The ECEX is nice too (this is the one I'm going to get). According to the Rep on the Manfrotto stand, elecronically and mechanically they are absolutely identical. Be sure you take the EX model since you want to plug it in the 8 pin socket.

The more I consider this, the more I think investing in an external recorder is the way to go. Quite a bullet to bite, but most economical per Mb and opens the door to 10bit if ever needed. The samurai is about the same outlay as a couple of 64Gb SxS.

The reason the PMW200 has the XDCAM 422 codec is so you won't need an external recorder. It's fully broadcast capable as is. The less stuff hanging off my cameras, the better.

Alister Chapman March 19th, 2013 05:38 AM

Re: Sony PMW-200 Brings HD 4:2:2 Workflow to XDCAM Camcorder Line
 
You have to think of SxS cards as a long term investment, just like the camera. They are not consumables, they are part of the system. Compared to tape, over the life of the cards SxS is very cost effective. I'm using cards purchased 5 years ago and they are just as reliable as the day purchased.

If you move to a pro broadcast system then expect to have to pay pro prices for the accessories that go with it. What your getting with SxS is reliability, very fast transfer speeds and peace of mind that it will work as advertised.

Yes you can hang an external recorder off the back of your PMW-200. Buy some SSD's and use that. But you will also need to figure out how to power it or take a second battery kit. You'll have to get some form of mounting system and there will be at least one cable between the camera and recorder. It adds weight and unless you are prepared to spend a decent amount on the mounting system it's going to get in the way and annoy you to the point where you won't use it. If you are going to use an external recorder you may as well save some money and just get an EX1 or EX1R.

I very much appreciate your input, Alister. It has helped clarify my thinking looking at this from the broader perspective. I think on balance I shall be following your advice for the time being. I do mainly gun and run stuff at the moment anyway. Outboard acquisition is a nice option down the road should it suit a particular project. 10bit colour does seem very rich and detailed, at least in the examples I have seen, and would be much more forgiving of post-production tinkering of course.

There really is not much difference between 10 bit and 8 bit acquisition with most cameras. The noise levels of smaller sensor cameras are bigger than the smallest 10 bit samples, so much of the benefit of having 10 bit is lost. What does bring benefits is lower compression gained through using higher bit rates. Compression adds noise and most compression systems break the image up into small blocks called macro blocks. In highly compressed systems, when you start to grade the image in post production these blocks start to become visible and more often than not it is these blocks that lead to banding in an image, not whether it's 8 bit or 10 bit. 50Mb/s 422 XDCAM is a very good codec and well matched to the PMW-200. Yes, an external recorder can be used to reduce the compression ratio, ProRes HQ at 220Mb/s will reduce the artefacts and give a very small benefit in post, but the benefit really is very small. With low noise cameras (typically cameras with sensors bigger than 2/3") then 10 bit becomes more significant.

As always what is far more important is how you expose the shot, how you frame it. An accurately exposed shot will grade much better than a badly exposed one. Using the most appropriate gamma curve for the scene can help maximise what's captured.

Terence, I've said quite a lot about 10 bit versus 8 bit in another thread which you may find relevant - http://www.dvinfo.net/forum/panasoni...m-tempted.html

Exactly right, and from the thread linked above it may be worth posting here again my suggestion for a simple 5 minute exercise with Photoshop which nicely shows exactly what Alister says.

Bit depth issues *MAY* give rise to banding, but banding is far more likely to be down to general compression issues - and I think that's exactly what you've found when you talk about your experiences with DVCProHD. (Which, as you say, is also 8 bit.)

I think most people can intuitively see why bitdepth may give rise to banding, but why compression should do it is probably not as obvious. If anyone wants proof, (and doesn't like theory! :-) ) then there's a very quick test you can do in Photoshop in less than 5 minutes. Make a new (blank) canvas, then select a narrow vertical strip on the left hand side and fill it with black. Select the gradient tool, and draw a line from the black area to the (white) right hand side of the canvas - the image should be a nice smooth black-white gradient left to right. Now try saving it as a JPEG - firstly with low compression, then with the highest level (quality=0).

Anybody still unconvinced that banding may be caused by over compression alone!? :-) If you want the (very basic) reason why, read on, if you don't like theory, skip the next paragraph!..................

Thanks, both Alister and David, for this useful input to my education. It's particularly interesting regarding banding, which I came up against a while back with somewhat less professional equipment. I was rendering to monochrome and playing with contrast curves etc, in post, but the results were basically unusable. I come from a still photography background and my interpretation at the time was purely in terms of having a limited bit depth to start with (as in raw vs. jpg). But there are clearly other factors involved in compression. In any context, it is sound advice regarding getting optimal exposure, as you mention Alister. I look forward reading further into this.

Raw v JPG is a bit of an apples and pears comparison, as the former is RAW data (so not a viewable image as such) whilst the latter is a "finished" product, but we'll gloss over that.....

There is another simple Photoshop exercise you can do if you're interested, which this time will simulate banding caused by limited bit depth, and how noise influences the resulting banding.

Start off as before. Form a new (blank) canvas, then select a narrow vertical strip on the left hand side and fill it with black. Select the gradient tool, and draw a line from the black area to the (white) right hand side of the canvas - the image should be a nice smooth black-white gradient left to right.

But now use the "levels" tool ("Image>adjustments>levels" on my version) and in the lower box ("Output levels") drag the right hand slider to the left until the bottom right hand box has the value 31. Click OK. Then go back into "levels" and drag the right hand slider in the upper ("input levels") to the left until you again get 31 in the corresponding upper right box, and click OK. You're back to a sawtooth - but heavily banded. This is banding caused by insufficient bitdepth - 5 bit, so it's hardly surprising!!

But now the interesting bit. (Well, interesting maybe if you're into geeky things... ! :-) ) Step back to the previous stage, and go to "Filter>noise>add noise". (I found a figure of about 2% worked well.) Now do as before - go back into "levels" and drag the right hand slider in the upper ("input levels") to the left until you again get 31 in the corresponding upper right box, and click OK.

And see the difference the noise has made!?! Still effectively 5 bit video, but the "dithering" effect of the noise has almost completely masked the banding. (Not that I'd ever advocate 5 bit video! :-) ) A couple of posts back, Alister Chapman said " The noise levels of smaller sensor cameras are bigger than the smallest 10 bit samples, so much of the benefit of having 10 bit is lost." Hopefully that Photoshop demo experimentally proves the principle of exactly what Alister was saying to be correct.

OK, you may argue that 10 bit can't be any worse than 8 bit, can it? With a 1/3" camera it may not give much of an improvement - but surely it can't do any harm?

To an extent - true. But generally for an acquisition codec bitrate is a precious commodity, within limits. Raise the bitrate, and you need more memory for a given recorded time, and higher bitrate may mean higher performance memory needs to be used. And 10 bit working will mean a 25% increase in bitrate over 8 bit with equivalent compression. I'd argue that for cameras in this class, for a fixed bitrate, that data may be better off used to lower the overall compression rather than give 10 bit - remember the previous Photoshop demo, and how it showed that banding could be equally caused by too much compression.

Of course, that may not be what marketing people wanting to sell you 10 bit recording solutions want you to hear.......... :-)
