Sony's HDV 1080i Consumer Camcorder

An anonymous reader writes "Sony has just announced a high-definition video camcorder that records in 1080i. A site was just created with a lot of information about the camcorder. The camcorder uses the HDV spec which records to standard MiniDV tapes. It includes 3 CCDs and along with the announcement it appears Apple and Adobe are now supporting the HDV standard. The camcorder carries a steep price at $3,700 though. See the original press release as well, though it doesn't contain much information."

For material shot and produced for HD, there should NEVER be any interlacing, EVER. Interlacing was only used as a cheap analog way of compressing the signal at a 1:2 ratio. Now that we have the bandwidth, there is no reason we can't have 60 discrete frames per second.

Or why companies that broadcast on two separate NTSC licenses (commonly known as 'duopolies') are only being given one 19Mbps ATSC license? Due to this, such companies can NOT offer true HD for both stations. If the analog side of your station broadcasts on two 6MHz channels (discounting translators, etc - just the main transmitter), then you should get two 19Mbps ATSC licenses, point blank.

If you watch 1080i originated material frame by frame in MPEG2 format, in fast scenes the color information is sometimes a frame ahead of the fast moving object... quite obvious when you pause the HD TiVo, but hardly noticable at all at 59.94 fields per second.

      The main reason 1080i is used and not 1080p, is because it allows for two progressive fields of 540p/59.94 which are then split up into an interlaced picture of 1080i allowing for smoother motion.
      I love 1080p/24 material, having shot and worked with it myself. I'm not as thrilled with 1080i, but it still looks fantastic.

      If TV as you know it is analog, then yes, Digital TV will be the end of TV a we know it, but it doesn't suck. The only thing that does suck, are cable companies not utilizing the full 19.4Mbps bandwidth. Most of the ones I have are closer to 9 or 10Mbps, and in high action sequences the mpeg just falls apart on the most compressed channels. PBS and DiscoveryHD usually have the best quality, but HBO is hopelessly compressed and since the compression is done in hardware, in real time, it can look awful in fast action scenes, while slow scenes still look acceptable.

If you have to convert to progressive, far better to use interpolation filters during encoding, rather than using bob or weave in the receiver.
      Interlacing, while it definitely does suck on projected images, is still a good idea for TVs and you're wrong, it was not used as a cheap analog way of compressing the signal at a 1:2 ratio. It was used as a way to get rid of flicker on your TV.
      30 frames per second simply isn't fast enough when shown on a CRT Tube. The image has a very noticable flicker. Using 60 fields, and showing them interlaced, promptly doubled the number of pictures visible on screen, and cut the flicker in half. It's still visible if you look, but for the most part, it's fine. Unless of course you have a very big TV, but then again, the NTSC standard was never meant to be seen on anything bigger than 12" anyway.

      I have an HDTV CRT, as well as a projector. If I don't de-interlace the signal that goes into my projector, it doesn't look very appetizing on a 100" projected image. However, my HDTV looks perfectly natural, as it uses scanlines natively.

      Material shot and produced on HD looks fantastic at 1080i, in its uncompressed state. The problem here is the 4:2:0 color compression of MPEG2, not the resolution. In fact, you'll see exactly the same kind of problems in PAL DV cameras (they also use 4:2:0, whereas NTSC DV cameras use 4:1:1 and don't have the color banding issues).

      Upconverting 720p to 1080i isn't as bad as you make it sound.

Thus, when converting to 1080i, each 720 is first blown up to 1080, and then split into two 540 line chunks, which are then interlaced on your screen. Since the motion is exactly the same in both fields, you are pretty much seeing a full 1080 picture, even though the source was 720 and thus not as sharp as 1080p.

However, we have a single DTV allotment that we run 1 HD stream (ABC HD or upconverted NTSC, depending on the hours), 1 SD stream at a good bitrate (the UPN station), a lower-bitrate SD stream that carries ABC News Now, and a couple of extra audio streams.

There is absolutely no way we could carry UPN in HD, with our fulltime HD stream for the ABC station.

      About the MPEG-2 issue - I agree with your points, but as I understand it, there wasn't much room left for the allowance of using a newer codec on your primary stream as they mature. I also understand that broadcasters can pretty much send out what they want, as long as they broadcast one MPEG-2 stream (SD or HD). But still, that MPEG-2 can take up a good chunk of your stream, if you run it at any quality rate. I'm not so much peeved at the simple fact that MPEG-2 is the primary codec in use *currently*, however - I'll definitely agree that MPEG-2 is the most mature codec in major use currently, at the average bitrates used.

      Perhaps I'm just over-worried a bit about it. I don't discount the possibility that ATSC will make room for a different primary codec when (if) they mature and produce good live results.

If you have to convert to progressive, far better to use interpolation filters during encoding, rather than using bob or weave in the receiver.
        Interlacing, while it definitely does suck on projected images, is still a good idea for TVs and you're wrong, it was not used as a cheap analog way of compressing the signal at a 1:2 ratio. It was used as a way to get rid of flicker on your TV.
        30 frames per second simply isn't fast enough when shown on a CRT Tube. The image has a very noticable flicker. Using 60 fields, and showing them interlaced, promptly doubled the number of pictures visible on screen, and cut the flicker in half. It's still visible if you look, but for the most part, it's fine. Unless of course you have a very big TV, but then again, the NTSC standard was never meant to be seen on anything bigger than 12" anyway.

      Well, we're both right on the original reason for interlacing, really. Of course 30Hz would have been a horrible refresh rate, but yet there wasn't enough bandwidth for a progressive 60fps signal. So, to compromise, the frame was split into fields to allow a 60fps motion rate and increase the total vertical resolution available at such a speed. Also, interlacing is clearly visible on even a small TV - but that's more the fault of graphics designers who think nothing of using one or two pixel horizontal lines with absolutely no interlace compensation.

      I'll agree that the current use of interlacing in DTT is pretty much a religious issue - I hate interlacing for exactly the reason you probably at least have *some* dislike for it, because it makes it hard to display properly on a progressive display. I might agree that, in a professional setting, mice teeth aren't wanted. However, when archiving existing 480i material on a progressive medium, at high bitrates, I feel the best approach is to encode the material with no deinterlacing done during processing, followed by encoding with a codec that supports the necessary metadata to denote progressive/interlaced and top/bottom field first (to deal with the specific capture device used). Then, you record the closest signal you can to the original video, and thus can utilize better deinterlacing methods that mature in the future. Plus, at least on an LCD monitor, I've found that bobbing looks way better than many people claim it to - there is an almost imperceptible loss in vertical sharpness, but the increased motion fluidity more than makes up for this. I'll also agree that it mainly depends on the original source of the material in the first place - definitely the best thing to do with a telecined 24fps source is to reconstruct the original 24fps as best you can with IVTC techniques. Also, there is material that is recorded at 29.97fps progressive and recorded on standard NTSC videotape - this material can simply be archived as progressive, of course. But for native 480i material, and for the purpose of archiving, I feel that no processing (other than color correction and blemish removal, if desired) should be done to deinterlace the material prior to encoding. For production and broadcast, I agree that deinterlacing is a good idea, however.

      True, it doesn't support 1080i, but it isn't "higher res" since the pixels are interlaced. What goes on normally is that you are recording 540p twice the rate. In theory, you'd have more horizontal resolution (1920 horizontally instead of 1280) but the Sony is actually recording 960 so the JVC beats it there. In any case, if your resolution is higher, it means that you need to give quality back by using a tighter compression to fit on DV tape, which both have to do. I'd imagine that progressive would be better for sporting events because the frames when frozen don't produce artifacts.

It also means that it can handle standard 480p DV video with no problem and no artifacts. Also it means no rectangular pixel scaling like you get in the the Sony either. Sounds to me like JVC's choice is actually better.

      Sorry, I forgot to refute this one in my previous post. Your statement is simply not true. To begin with, when digital cameras came out on the market, the options available to filmmakers were limited. There are a number of things a photographer would consider in choosing his gear for a shoot. Perhaps the right lenses weren't available for the camera. Also, there is the cost. If you have a bunch of money invested in film equipment (literally hundreds of thousands of dollars), why should you go out and spend a bunch of money on equipment that simply allows you to do what you already can. For big budget productions, why not take advantage of film?

      For smaller productions, why would you jump into uncharted territory. Independent producers and production houses bid on projects. If something goes wrong during the production, and it the fault of the production company, then they eat those costs. If you want something to get off without a hitch, use what you know works.

      So why didn't the big studios switch to Canon XL1s to shoot their $20 million actors. Because Canon XL1s don't make $20 million actors look like their worth $20 million.

      And even now that HD cameras have become more practical for production use, they still don't replace film. 78mm and IMAX film are still used to capture the highest resolution images. Also, the color space of video is no where near that of film. In fact, there is no black in video. Black in film is the absense of light. But in NTSC, black is 7.5 IRE, which is a measurable quantity of light.

      Further, film processing effects, such as those used in Seven, can only be faked digitally.

      Also, until more progressive scan cameras reached the market, no one was interested in shooting interlaced. It had nothing to do frame rate, but everything to do with picture quality.

(Just as an aside, the reverse of this is often done when movies are shown on European TV, which are filmed in 24fps and shown at 50Hz interlaced (ie 25fps) on PAL TV. This sometimes explains why films have slightly different running times on European and American TV, and some actors complain that their voices have a higher pitch when they watch their movies in Europe)

    Now this camera does not support either of these 1080 line progressive scan modes, presumably because the CCD sensor in the camera would have to be different to do this. It can apparently film 1080i 60Hz and then fake 30fps or 24fps progressive from that, and I would be very interested to see how good this is. It is undoubtedly much better than the old PAL DV camera at 25fps trick, but how it compares with cameras that film 720 lines in genuine progressive scan remains to be seen. These 720p cameras have apparently been a big hit with film-makers, but a genuine 1080p camera for a few thousand dollars would be something special. It would mean that film-makers could rent a camera for a few hundred dollars that could produce something very close to genuine cinema quality, and they could make movies with it without the costs of film stock. Sony have been making 1080 line 24p cameras for professional use for a few years now ("Star Wars Episode 2", the "Spy Kids" movies, and no doubt a few others have been shot with them). This would change the independent film world, as the absolute minimum amount of money required to produce a feature film with decent picture quality would be reduced from a few tens of thousands of dollars to close to nothing.

More and more festivals are getting rid of the snob "film only" attitude and realizing that digital is the future. 24p is not some magic number that instantly makes your film from crud to pure genius. yes many MANY Indie filmmakers chase that "holy grail" with blinders on.

      24p is not magical. And unless you are looking at doing a reverse Telecine to get your video onto film stock, it is purely stupid to go out of your way to do so.

      I suggest that most people work on their Script, getting decent actors, and actually learn how to shoot a scene before wasting money on chasing the 24p myth.

  44. 1080i /= 540p by JesusQuintana · · Score: 1

    Forgive me for stepping on your words:

    Basically, 1080i = 540 lines / refresh. 720p has 720 lines per refresh.

    but it seems you are implying that 720p is a higher resolution than 1080i. You are correct that more lines are refreshed during each scanning pass in a progressive scan format. However, the refress rate is half as often.

    In progressive formats, all of the screens pixels (each frame) are refreshed every ~1/30 second. In interlaced formats, each frame is made up of 2 fields and fields are refreshed alternately every ~1/60 of a second. In the end 1080i has refreshed 1080 lines of resolution in 1/30th of a second, while 720p has refreshed 720 lines of resolution in 1/30th of a second. In the case of 1080i, the gun is spraying electrons much faster than 720p.

    The alternation of even and odd lines is virtually invisible to the eye when dealing with slower moving images. Our eye's persistence of vision continues to see the odd lines of the TV image while the even lines are being displayed. The reason films run at 24 fps is because that is that is the point at which the human mind percieves continuous motion from individual stills. (You may have noticed that sometimes when you see silent films that they appear to be sped up. This is because they were often filmed at 18 fps and played back at 24 fps. Film is expensive, especially back then! (Film contains silver.) Shooting a film at 30 fps, instead of 24, would add 25% more cost to film stock and processing. Why raise the budget with very little visual impact?

    Also, folks often confuse the way things are acquired and the way they are distributed. Just because something is distributed in 1080i does not mean that it has to be aquired in an interlaced format. For example, the Panasonic AG-DVX100A is a prosumer 24p camera. But it uses the standard MiniDV format to record the image. The image is recorded at NTSC 29.97 interlaced. All of which is explained here by Adam Wilt. By using 3:2 pulldown (RTFA), the 24p images can be encoded and displayed on standard 29.97i NTSC equipment. The same technique is used to produce DVDs.

    The difficulty of interlacing is that when motion occurs quickly, the odd and even lines don't seem to match up correctly and can create moire (that weird visual pattern you see when somebody wears a tightly striped shirt on TV) or other visual distractions. However, this effect only applies to images that are acquired interlaced. If the images are acquired progressively and displayed interlaced, you will never notice the problem. 1080i, if care is taken in the acquisition phase, should always looks better than 720p.

      No, they were right, but the term 'refresh' should really not have been used. 1080i has 540 lines per field - 540 per odd field and 540 per even field, displayed alternately on a screen refreshed at 60Hz. 720p has 720 lines per frame, and 720p supports 60fps operation on a screen refreshed at 60Hz. It also supports 30fps operation on a screen refreshed at 60Hz, frame-doubled.

      With 1080i, the fields can be combined into a full frame, and you get the whole 1080 lines of resolution, but it comes from two distinct moments in time, and each of these distinct moments is only captured with 540 lines of the full 1080 lines of resolution. With 720p, each distinct moment in time is captured with the full 720 lines of resolution. So yes, 720p does have more temporal resolution than 1080i.

      Also notice that I say 'lines of resolution' to mean literally what it says, and not the traditional video meaning of the term, which is too complicated to describe here, and should only be applied to digital video when attempting to compare it with NTSC.

    I do professional documentaries with two Sony VX-2000 cameras, and occasionaly do studio shots with a very old Sony DXC-3000A connected to a DV (FireWire) converter and recorded directly to hard disk. I have also started to dabble in the area of live editing, by using analog equipment to switch/mix cameras, run effects, insert titles etc. while broadcasting over QuickTime Broadcaster and recording to miniDV simultaneously. Which brings me to the reason I won't be switching over to HDV anytime too soon.

    First of all, there just isn't enough demand for HD format. Most people don't have TVs that can take it. Second of all, there's no universal format beyond miniDV tapes to distribute it on. Finally, my work is more in the actual content of the documentary than the quality of the video itself. (In short, it's not a music video or movie.)

    I'm also not sure how good the new HDV camera looks. Yes, it has a much higher resolution than any non-HD camera, but resolution is only part of the story. My DXC-3000A which is a very old 3-CCD studio recording camera (not a consumer model) doesn't even come close to the resolution of my VX-2000. But it looks better. There are several reasons for this. Larger CCDs (not necessarily better resolution), higher quality lens, overall stability, and signal processing. You still can't cram that much into the size of a VX-2000. I suspect when the consumer model HDVs come out (the current ones are prosumer at best) my DXC-3000A will still beat them in general quality, even with the lower resolution format. Of course, my friend reminds me that his Bolex 16mm film camera beats ALL of my equipment anyday. Luckily, I don't have to wait a week for my film to be developed, and it doesn't cost an arm and a leg to work with.
