Hmmm...
That actually makes sense and certainly would be a significant negative issue for the VG10. |

IIRC from the discussions that were reported with Sony execs, these "issues" were part of why Sony DSLR-V's weren't showing up to the party (there are apparently two SLR's and two mirrorless bodies coming VERY soon). I suspect Sony wants a "smoother" end user experience rather than the "creative" approach that most DSLR users have taken up to this point.
Sony's "answer" apparently was the "E" mount, with an entirely new line of lenses optimized for video... I'm waiting to see what they do with the A550 replacements, which will still use the Alpha glass but have video. Sony is walking an interesting path, as there's a substantial community of Minolta/Konica users that were promised continuity and future enhancements with the Alpha mount... so do they allow Alpha mount with "issues" and a standard DSLR format, or do the put the $$$ into the "E" ticket, or BOTH? I know if I can get a video capable Alpha body for those DoF shots, I'd just as soon keep my existing glass than buying new lenses, as the Alpha covers the "still" side primarily, and video as an "extra"... The VG10 is a different animal as it comes at things the other way around, but it has its own appeal. Mike - I hear ya on the "sentimental" value of the FX7, I miss mine, was hoping it wouldn't be long before Sony hit with a similar tapeless camera - whoops. The VG10 is the first cam that's caught my eye in a "big" camera, definitely will be checking it out, but my CX550's cover me very nicely right now. And yes, the improvement between the CMOS in the SR11 and the "R" CMOS that showed up in the XR500 is substantial. It's the same sensor as in the 550, but the rest of the camera has been refined significantly along the way - the 550 OIS is impressive in smoothing out bumps, 3.5" LCD is finally about right for "older" eyes, I personally like they finally put a VF on the CX (flash memory) series, previously you had to have one of the HDD cams. |

I align the 2nd system sound waveform with the camcorder waveform. Really not that difficult. But it is usually a music program, The aggressive leading edge attack envelopes make it easy. So I guess those are my "clappers". If it was just voice, or soft and indistinct (background nature sounds for instance) you're right, it would be much harder (impossible?) without the clapper. |

As for the AX2000 (FX1000) not being its replacement due to the chip size, for all intents and purposes they are the replacement, at least to me. I am still impressed with the PQ of the FX7 and probably would be even more impressed with that of the FX1000/AX2000. As for the difference between the SR11 and XR/CX550, I will have to check one out if I can find one around here. BB is the only place besides Sears that sell these things up here that I know of, and BB only has the XR, so no chance on look through the VF (only the LcD). Now if only they could produce something like the VG10, but with a 20X zoom (standard). I guess there's always next year. |
Mike , the XR has the viewfinder. It was the first CX series that didn't have the viewfinder. I can confirm that the XR500 is visibly better than the SR11 frankly challenges my NX5U. All are better than my FX1( which is why I got the NX5U)
Ron Evans |
Thanks Ron. Sounds like the XR would be the one for me. However, I am disappointed that it does not have a better zoom (ditto the SR11). Even though I have read this entire thread, I can't remember many of the details. So, please have patience with me as I ask: How is the VG10 different from the XR 550/500 other than the ability to switch lenses? And, since I mainly shoot outdoors (nature, scenery, trains, Blue Angels), would the shallow DOF be a problem for me?
Thanks. Mike |
Mike if you do not want to have a shallow depth of field or change lenses then there seems to be no point in getting the VG10, that's most of the reason. If you shoot fast motion then that is also a negative since the VG10 appears to shoot 30p in a 60i stream. Unless others have a different point of view the VG10 is not for you.
Sony XR cameras have hard drives the CX flash memory. So the XR550 has a hard drive the CX550 has flash memory otherwise they are the same camera( the CX is a little smaller since it has flash memory not a hard drive to house). Ron Evans |

Also, the FX1 has CCDs, not CMOS. Either way, I think I'd rather have a AX2000 than an NEX-VG120. But the NEX-VG10 vs the FX7, that's a lot harder to decide; probably risk the NEX-VG10. |
Hi Mike -
Can't blame you for keeping the FX7 one bit, it's a good camera, and yours has added sentimental value! Think of the VG10 like an SLR - it complements the CX550... or other traditional video camera. The CX550 has a huge DoF, virtually unlimited recording time, and of course the 550's have an unusually wide "wide end" of the lens range (it's like putting a .7x WA adapter on your SR11, or XR500). I was worried about the long end, but frankly even when using the digital zoom, the "R" sensor stays pretty darn clean through a good part of the zoom range. The optical zoom is no great shakes, but I've always put the digital zoom on "in case" and tried to stay "below the line" that shows up in the sony zoom indicator. In the 550's they only put a single digital zoom setting (150x), where earlier there was a "digital doubler" option (20x), which I preferred, as signal degradation wasn't bad, and it left you with a more controllable optical/digital "mix". The VG10 gives you the ability to get really shallow DoF, and mount other lenses for special purposes, but still in a relatively small handheld package. Optical zoom will be lens dependent. IIRC the IS moved into the lens, which may or may not be good, I'm spoiled by the OIS of the CX500/520/550, which added even more stability to the XR500 OIS. I don't know yet whether I'll go VG10, or whether I'll pick up one of the new Alpha bodies with video - I know I want the ability to do the shallow DoF "glamour" shots, one way or another. They are two very different tools in design and execution, where the AX2000/FX1000 are more traditional "video cameras". Personally I prefer a smaller camera, thus why the FX7 sits in such a unique spot. As Ron already clarified, traditionally in Sony model nomenclature, SR and XR designated HDD cameras, while CX series had no onboard memory, no viewfinder, no I/O options for headphone/mic, and recorded to MS Duo. The CX550, released simultaneously with the XR550 departed from this tradition, adding 64G onboard flash in addition to the MS Duo/SDHC slot, mic and headphone jacks, and a viewfinder, all still in a small light package - basically an XR without a HDD, and IMO a close to perfect package. I always liked the CX's for size and weight, but the lack of features could be frustrating, the CX550V hits the correct mix IMO. I know what you mean about it being hard to find the higher end cameras if you're more "rural" - our "local" "small footprint" BB barely stocks anything, and rarely has any "high end" to be found... I can say I don't think you'd be disappointed in upgrading your SR11 to anything with the "R" CMOS, I didn't expect it to be as much improved as it was. |
Thanks Dave. You have helped me clear some of the haze that was fogging my thought process (either that or my trifocals are dirty). I will have to take a closer look, maybe when I travel down to Chicago in a week or so.
I appreciate all the comments and help from you all, especially Ron and Dave. I always enjoy reading your posts. Mike |
I don't know if the argument about the VG10 being an inerlaced camcorder or it being a progressive camcorder that interlaces the video is still ongoing or not, but, here's what I found on Sony's website.
The NEX-VG10 has the same sensor format that Sony builds into the full-sized α DSLRs. Video is captured at 1920x1080 30p (29.97i) and recorded in AVCHD 60i (59.94i) format. With 19.5 times the surface area of conventional camcorders, the large Exmor APS HD CMOS sensor makes capturing cinematic video with a shallow depth of field a breeze. http://www.sonystyle.com/webapp/wcs/stores/servlet/ProductDisplay?catalogId=10551&storeId=10151&langId=-1&productId=8198552921666239819#additionalImage1" |
Just like the still cameras in the E series it will record the whole frame. Likely the electronics cannot manage this at 60P ( yet) so 30P is it. For playback compatibility on TV's it needs to be 60i.
For 30P in AVCHD 60i each odd and even field does belong to the same frame so "adding" them together will create a 30P stream. A true 60i stream is constructed from fields that do not belong to common exposure frames. The fields are actually taken 1/60 sec apart. ie a 60i camera is a 60P camera that only records or transmits a field for each of its exposure frames. Sometimes the fields are scanned as fields and other times ( like the new Panasonic TM700) they are full progressive frames. So with this in mind the VG10 will have the temporal motion of 30P even if watched at 60i. This will fit nicely for shallow depth of field film type shooting but will have judder when panning or shooting motion that moves across the screen. Just like 24P. I think Sony have been quite smart. This camera will give a sort of film look on whatever its played back on. Ron Evans |
I wonder, what will the video quality be like in comparison to a 2/3" HD cam? With that large sensor and interchangeable lenses, it might even make better video. It will most certainly have better depth of field control. And all this for $2,000? It may be marketed as a consumer cam, but I intend to use it professionally. I can't wait to get my hands on one.
If you go on a certain forum site that deals mainly with 24P products, they're tearing this camera a new one. How dare Sony only offer interlaced? Blah, blah... I don't care. Most everything I shoot goes directly to broadcast, so I'm comfortable with 60i, or 30P, or whatever it shoots in. |
Quote:
I suspect that in the day to day world of commercial video production, 60i is probably still #1, 30p a significant #2, (60p an up and coming), and 24p a distant third. Sony certainly must have a good feel for these numbers, know it's target marketplace rather well, and have some pretty solid ideas of where the camera sales are going to be. 30p in 60i wrapper: Gets the 30p crowd, works natively with all 60i postproduction pipelines, goes to Blu Ray Disk 1920 60i without a hitch- I thought it was pretty clever of Sony. It straddles all of the markets except 24p. |

True fact!!

I take it that with the proper software, one could retain the original 30P from the 60i, if one chooses to. Any good de-interlacing software anyone would recommend for such a task?
|
The typical "deinterlacing" software that we use for true 60i to 30p conversion would not be recommended, as it would alter the fields in its attempt to "blend" them into single frames.
I have no first hand experience with this yet, but some posters have indicated that simply importing the clips to a 30p timeline is all that's needed. Apparently, the NLE should interpret the footage correctly. That will be sweet, if it's really that simple. |
Bad News Regarding the Sony A Lenses
There's been a lot of speculation as to the level of function of the Sony A lenses with the VG10, particularly regarding f-stop control by the camera.
I just discovered a footnote on the main Sony Style VG10 webpage that confirms the bad news: "3. Attaching Sony A-mount lens requires LA-EA1 adaptor (sold separately). Manual focus and full open aperture shooting only." I guess there's always hope that Sony might cook up something like an f 1.4, 50mm prime E type video lens if this line of cams is successful. I'm concerned that the VG10 will not provide the CX550 class of low light performance with only f 3.5 max aperture. An f 1.4 lens would be around 4 stops faster- an entire world of difference for available light photography. |

Seems like there have been very clear signals that Sony does have a ramped up version of the VG10 in the works, supposedly to be announced by the end of the year.
It could be the same body with some XLRs added to the handle, plus a few extra buttons, or could be a bigger body- essentially a whole new cam based around the same APS chip. Rumors are that it will be priced in the $4,000 range, so you would think they're going to have to give more than just a couple of XLR plugs. We'll have to wait & watch. |
I just hope Canon comes up with something in the $1,200-$2,000 range. I can live without XLRs. The lack of 24p is a little harder to overlook.

1) 60i is 30 FRAMES per second. 2) 30p is 30 FRAMES per second. There is NO frame rate difference between the two, hence no timeline difference, You can use a 30p timeline or a 60i timeline. Both are 30fps. The only difference is that with CCD/CMOS captured 60i the odd lines and even lines are captured 1/50th or 1,60th second apart while with 30p ALL lines are captured at the same time. This very simple difference has five implications: 1) With 60i, the odd and even lines make up 2 FIELDS that, on CRTs, are displayed one after the other thereby providing a FIELD TEMPORAL RESOLUTION of 1/60th second in contrast to 30p that has a FIELD TEMPORAL RESOLUTION of 1/30th second. This is why motion looks more smooth with 60i. 2) With flat-panel displays 60i must be deinterlaced. Simply put, each FIELD is converted in SIZE to a FRAME. Thus 60i is converted to 60p. Therefore, the FIELD TEMPORAL RESOLUTION remains 1/60th second. 3) Because SCALING must be done by FIELD (interlaced video) or FRAME (progressive video) your NLE needs to know what kind of video is in the timeline. BUT, as long as you set your timeline to INTERLACED all will be well because scaling the odd lines separately from the even lines does NO harm to progressive video. So all this talk about editing as progressive is a waste of time. Simply edit based upon the recorded format -- which is why Sony calls it 50i/60i. 4) In fact, if you want to burn a BD, you want to keep the timeline as 60i because it will happily output video that can go to a BD. BD does not support p25 or p30. 5) If you want to go to the web, DO NOT DEINTERLACE! When you compress, be sure the output is H.264/AVC as this codec has no tag "i" vs "p" tag. (Apple allows assumes H.264/AVC IS progressive.) Folks are overthinking this. |

UNLESS you transfer to film and watch in a theater you have not ever seen 24p. UNLESS you transfer to film and watch in a theater you have not ever seen 24p. All this 24p talk -- unless you transfer 24p to FILM -- is nonsense! What every person demands -- they will never get when viewing on any home video device -- except the Kuro. What you see on ANY video device is 2:3 PULLDOWN JUDDER present in 60i video. 2:3 PULLDOWN JUDDER present in 60i video does NOT look like 24fps projected film. 24fps is smooth -- with low temporal resolution. 2:3 PULLDOWN JUDDER is NOT smooth but has low temporal resolution. What is smooth AND has low temporal resolution? What looks like real projected film? 25p and 30p. When folks claim they can see the difference between 24p and 30p they are actually saying they can see the difference between "smooth" (30p) and "non-smooth" (2:3 PULLDOWN JUDDER). Somehow they have lost the fact that real film projected is smooth. So from now on lets get real. Please say "The lack of 2:3 PULLDOWN JUDDER is a little harder to overlook." PS: you don't even see 24p on your computer because LCDs run at 60p. You see 2:3 PULLDOWN JUDDER. |
Well said Steve. Both posts.

The issue I was attempting to address in my post was the issue of using the VG10 30p in 60i footage on a 30p timeline. For example, to mix VG10 footage with true (non pseudo interlaced) 30p footage on a 30p timeline. Some have suggested that you can simply import the raw VG10 clps to the 30p timeline and the NLE will interpret it properly. I don't know if that is correct or not, and I don't know if all of the footage would be processed identically when rendering out to final formats. |

The judder problem with 2:3 pulldown is each frame is _not_ shown for a true 1/24 of a second. Frame periods can only be either 1/30 (2 60i or 60p fields) or 1/20 (3 60i or 60p fields) of a second and is easily perceptible as _variable_ judder for fast moving objects. 24p still has judder but it is even and invariable for fast moving objects. Today it is possible to purchase home displays that can show a progressive frame rate of 120 Hz. These displays (disable the oversampling/judder removing "smooth scan"/interframe interpolating technology) can reproduce a filmic 24p experience in a home setting. The 120Hz display shows the same progressive 24p frame 5 times (vs the theaters 2). Temporally this is equivalent. Both show a single frame for a true 1/24 of a second. Perception of judder is equivalent. I think it can be argued that one is seeing true 24p with a 120Hz display as much as they see true 24p from a 48Hz projector in a theater. |
Its not wrong to want 24p, just because another doesn't have a need. In fact I think 30p is great looking and 60p even smoother, but for technical reasons associated with your final production needs, 24p may be the right way to go.
24p is wanted by film makers who want to have the same amount of frames in a second of film, as are found on one second of 35mm or 16mm film in modern cine film production. Most 24p formats give you 24 single frames of film. In some of the formats, particurly in HDV, 24 p is laid into a 60i format, of 60 half frames per second. That does not mean that the information is not there their to extract those 24 frames into true 24 single shot frames. It is there, but has just been laid into the 60i stream to create the 24p frames, while conforming with the HDV requirements. Many will use a convertor like Cineform to remove pull down, and at that point you will begin working with only the 24 frames per second. It will save space and time. Now why do so many film makers want to use 24p? While they say that, I don't think it is because they feel it shows better on video screens. While they say they can tell the difference, the main reason is that film outs (the dream of most cinema film makers) are 24p. Obviously if you shout in HDV 60i, some frames have to be thrown out to get 24p, and it may even be that interpolation will have to occur. Kind of a crappy thing to do, if you can just get it all by shooting 24p in the first place. And from my experience with 30p to 24p conversion with the Canon 5D material, even more problems occur. As to the judder thing, I am finding that it doesn't show up if you are panning properly, and shooting at a proper shutter speed. And I do have to disagree that you don't seen judder in 35mm celluloid films. I believe I have seen it on many occasions. Control of camera movement is the key to preventing issues there. |

There is a difference between the flicker rate and the frame rate. Film projectors can have 2, 3 or even 5 blades ( mine at home have 3 and 5 blades) this reduces the flickering of image on the screen only. The exposure rate at which the film was taken is 24 fps in most cases and it is possible to ensure that there is no judder. Lots of books have been written on this subject and any film school or even film clubs will focus on this to get the best picture possible within the constraints of what was an economic decision. Nothing to do with art or technology but was the best compromise for motion and optical sound performance with minimum film stock used and distributed.
Yes modern 72hz, 120hz and 240hz displays technically have the capability to show true 24p with flicker rate at display refresh rate but the playback chain has to be complete at this level for it all to work properly. ie compatible Bluray player/display and HDMI interface etc. The vast majority of viewers do not see 24p on their systems. They see a modified form depending on their systems and almost impossible on normal CRT's. Shooting 24p video to me only has value if the intent is to go to film for projection. 30P would be a better choice for the film look if the intent is never to go to film. Personally, I don't like either and was so glad when I moved from film to video. Ron Evans |
Ron -- glad you pointed out the need for the entire chain to support 24p.
And I'm glad to learn of the LG -- did they buy the Kuro line? The maximum presentation rate for film to look like film is 96Hz. And with video, the minimum is 72Hz. There are only a few HDTVs that meet these specs! The vast majority of those wanting 24p do not own these monitors. Likely 1% of their audience has the few HDTVs. Thus, NONE will ever see 24fps. EVER! They are asking for 24p because frankly they are uneducated about video tek. Having no understanding themselves they lemming like repeat what they heard. What they think is the film look IS 2-3 pulldown not 24p. What will most look like theater 24fps is 30fps. They demand 24 for was valid when video was going to transferred to FILM. It has no validity now that indie productions are watched on flat-panels and computers. PS: you can always put 30p in a 60i timeline. |
Ok, well I happen to like the 2:3 Pulldown Judder look.
