Frage von Flipser:
Hello together!
It comes as an advanced amateur filmmakers ritener actually no longer around to HD, if only, if you shop around or read magazines. My problem is this: I lack a little basic knowledge. Since there are so many terms, one of which is talk that Blu-Ray is a format, but I thought it is only a medium or what is the difference between AVCHD and Full-HD and why is it so difficult to cut even though it supposedly same size as DV and why HD is not larger, which is working with Interlase and what does not and, anyway?
These are a few of the questions at me screaming for an answer.
So anyone knows a good website to read or where you look quite fundamental about high definition information is most easily started? I would be very grateful for a tip! Thank you!

* blue-ray really is primarily a medium, however, synonymous associate a certain video encoding so, namely that which the Blue-ray player (which you connect s.den Screen) can decode ... Exactly the same is with DVD: eigtl a medium ( "data DVD"), but synonymous associated with a specific video coding (all available for sale and self-DVDs Video-DVDs use the same type, the video coding, which is based on MPEG 2, thus all DVD players can play!)
* HD stands for High Definition, so high resolution, there are two specifications: one 720 vertical scan lines, and even 1080 vertical scan lines. p and i behind it indicate whether it is progressive or interlaced:
eg means 720/50p: 50 frames per second with Resolution720 * 1280
1080/50i: it is all a half 1/50s (alternately straight and all odd rows) to the vertical resolution of a half is only 540 lines. When motives are therefore theoretically Resolutionvon 1080 vertical lines (VL) is possible
* With a 16:9 picture are calculated image size 720x1280 and 1080x1920, with HDV to save the amount of data only 1440 horizontal pixels, are then in a horizontal direction are stretched. Cameras, the images in full horizontal resolution (ie, with 1920 pixels) at a time are considered "FULL HD" means, although that term is synonymous otherwise marketed, thereby "FULL HD" yet says nothing at all ..
* Previously, I spoke of the Resolutions, in which the video data are recorded. The real physical resolution (as fine objects are not blurred), however, experience significantly lower (a little over 600 VL). The real resolution is synonymous with the encoding specified.
* To the enormous amount of data of a high-resolution movie on tape or on the hard drive / memory card to get the data must be compressed: this is the video encoding responsible. (For DV, there was no strong Compression. For equally compressed HD material you would need for one hour film about 45 GB of space ...)
And here there are different formats: in principle based on the HD encoding either MPEG2 (HDV, JVC's MPEG-2 TS) or MPEG4 / H.264 (AVCHD), using MPEG4 more compressed than MPEG2.
* The greater the compression, the more difficult post (analogue: the more intelligent and space saving is a crockery cupboard concedes, the more utensils fit into a closet-size solid, however you need to Get Published (Edit) a rear cup synonymous correspondingly longer). For editing of HD material, you must then decode the video first, then 3.5 times as many pixels edit and then re-encode, which hold more effort, vswenn the encoding space and so complicated and rechenaufwändig is ...

Only one thing I am still nothing .... AVCHD. I thought it would, so to speak, the improvement of the normal HD, since it is with 1920 pixels is, in contrast to the normal HD procedure, which creates only the 1280 .... Now I hear, however, that MPEG 4 (with the AVCHD works) is more compressed than the normal Mpeg 2 HDs. What is better now?

AVCHD is a generic term MPEG4 / H.264-based, for high video resolutions suitable data reduction techniques. AVCHD is designed to 1920x1080 - not everyone uses it but camcorder.
The second, in normal camcorders, high definition format called HDV, and supports up to 1440x1080 - not 1280x720.
. Now I hear, however, that MPEG 4 (with the AVCHD works) is more compressed than the normal Mpeg 2 HDs. Right.
What is better now? In general, format with high data reduction have advantages in space, but are more demanding when cutting / finishing. So you are buying you an advantage with a disadvantage. Among the opportunities and post-impossibilities of AVCHD and HDV is here in the forum have said it all ...

To dieViertelswissenverschwurbelung ... even more attractive eighth ...
AVCHD is merely a registered trademark of Matsushita Electric Industrial Co., Ltd. (Panasonic) and SonyCorporation.
Under the trademark, the company camcorder on the market, the z.Tl. a profile from MPEG2 (4:3) using H14 and partly both HD format 1280x720 and 1920x1080, because there are 2 (real) HD format. Not only is HD 1920.
The brand uses the AVCHD compression technology of MPEG-4 H.264.
This is an evolution and addition of MPEG2.
Numerous changes have the new standard so effectively done that testing of the "Blue-Ray Association showed that s.16Mbit / s with a feature film, the difference with the original is no longer observed.
Insofar H.264 with MPEG2 is not really compare, because such a result would be with MPEG2 can not be achieved.
S.einer German university studies have shown that the computing power required for the encoding is dependent on what tools you use and how well the tasks of the software are distributed.
The requirements vary between the 1.6 and the 3-fold compared to MPEG2.
Both 2, as synonymous 4 thread x86 are capable of real-time requirements. (Limit to 2 threads about 10 Mbit / s (60 images) and 4 threads about 15 Mbit / s (60Bilder)) --
This in addition of CABAC, the current extreme requirement s.den Calculator.
Without CABAC see the data much more relaxed and only the Singel Tread rising real time at 10 Mbit request.
The 2 and 4 to 20 Mbit / s with 82 or 102 frames / sec, so they have more air.
The myth that the calculator can not do everything, so the land belongs to the legend.
Of course, it is synonymous depends on how well an NLE and distributes the tasks of course synonymous, what other things on the calculator so s.Tasks "accelerate" are.
Such things can be a CPU of course, synonymous in the knees. This then has nothing more to do with H.264.
Otherwise, MPEG 4 still so many improvements that are already listed here all have been.
Note that obviously synonymous HDV 1280x720, that is defined according to the SMPTE HD, compared to 1440x1080 which is 4:3 as MPEG2 format is defined (H14) and only by interpolating to 1920x1080 done.
Among the aforementioned camcorders is to say that it is currently synonymous HD format 1920x1080 only reach by interpolation and not "real" Resolution Support.
Also does that mean "seal FullHD" this is not, but only that the devices s.Ein or with the output signal can bypass. Not but that in the full Resolutionerzeugt should be.
As far as relating to Viertelswissenverschwurbelung.

Hello anonymous guest.
Maybe I am so honored that you are my contributions every time and very carefully read.
And yet it seems that the attention is not sufficient, because there are some you like, of me again and again repeated Details escaped.
1) I have always repeated that the proceedings must be established. The fact that the company synonymous opportunity to be their algorithms to develop and implement in products.
2) That the quality and efficiency of the products greatly the ability of this proprietary developments dependent.
3) The fact that broad-based with hardware assistance is to be expected, which, of course, primarily Cam, TV, Mon, etc., so mass-produced products. That the development of niche products such as PC cards, a relatively low priority with you, everyone can probably understand.
And your information comes from that all hardware products to the camcorder production?
4) The fact that not all the (cheap) supplier of NLE synonymous AVC will offer (theme license costs), that not all NLE manufacturers offer good solutions (see above).
5) You obviously synonymous've overlooked that very active users, such as Marcus here several of the current configurations correctly reported, are already running. (Search effort)
6) My window is always on the 2nd 3.Q 2008 and once lay. It has HDV almost 2 years to European format, even of major manufacturers supported.
So what do you want to achieve with your impatience or point?
7) Have I ever purchase of a current of AVCHD parts discouraged. If you really have to be carefully tested, are the reasons you are not missed.
8) The output of (any format) is not a matter of H.264 but the manufacturer of your software is.
... once again to note-taking: H.264 is a bitstream and no en-or decoding!
One has been slightly bring understanding to be able to differentiate what I've missed your request.
Here, everything just described: http://www.lulu.com/content/1094660
About the merits, we need no longer argue that one can a day in HD and watch television with the search function here.
I consider myself in this matter s.die provable facts, as described and not s.subjektive observations, their causes can be as individual as the users themselves
Also my experience with H.264 are described in detail.
Otherwise, who prevents you from the system not to use?

These are two very tyische statements, which fairly well the current situation with AVCHD devices describe. Indeed, we have in the PC world so far only Pinnacle Studio 11 + and Vegas 8, which "native" AVCHD material in the timeline and set halfway sensible editing. Edius or VdL can theoretically synonymous, but the preview capabilities are quite limited unchanged - if not for Intermediate Codec converts.
But with these two solutions is a halfway reasonable AVCHD editing possible - at a sufficiently fast PC like Quad, failing even to 2-core systems (but you can almost no longer recommended for AVCHD natively). And it almost certainly synonymous color, but the preview capabilities are synonymous on a quad but clearly limited than that of HDV or DV.
Therefore, the intermediate solutions is still a good choice if you want to edit AVCHD - above all the solutions of Canopus with the Canopus HQ codec, or if necessary synonymous solutions of Cineform, or synonymous with VdL mpeg2 as "Intermediate" (limited, what the number of possible generations rendering is concerned, but doable).
And the action in the 2nd Above statement is, unfortunately, very typical: always fall back on the user enters AVCHD devices, make only in hindsight find that they now have a camcorder, but do not stop clever cut can. One can only advise against it - and try, the people with information to provide. But if someone does not find in the forums, and only in various markets to buy - then it could be that he or she is holding fall purely as synonymous.

And here is the point exactly, that you
- In the case of AVCHD content but should use the Quad
- In the case of HDV, even with a loose Duocore anymore.
The prices are no longer the huge difference, it's only stupid if relatively short time until one Duocore bought. For the Duocore invest halt ideally in Canopus Neo, and hesitate on the matter from Intermediate codecs. Would I personally even synonymous with the quad to make.
All other investments - in full HDTV or HD-Ready in Blu-Ray authoring software and Blu Ray burners and Blu Ray player, both in the case of HDV as synonymous in the case on an AVCHD to. Although there are cheaper solutions synonymous always find out if you want. So you can take around the still quite expensive Blu Ray player / burner synonymous to other HD-capable devices go - such as in the Xoro HSD 8500, the HD mpeg2, DivX HD, HD-wmv perfectly clean plays - for 150 euros for Karstadt is available.
Really expensive, the thing if you also cineast is still synonymous and the HD sound formats Purchase Of Blu-Ray discs will have - such as True HD. Then keep one's time only a few expensive Blu Ray player, and even more expensive A / V receiver. Only then can no longer blame the Videofilmerei - the stems so the more cinematic aspect. Apart from that, so far synonymous priced higher, standard NLEs eh up only 5.1 encoder interface (like Vegas 8, Adobe CS3 can encode, but supports my knowledge, not even AC3 5.1 sound on Blu Ray discs, however, Vegas 8 already).
It's about an even more expensive Blu Ray burner temporarily save when some AVCHD DVDs (BDMV structure to normal DVDs) erstelt - such as with the Ulead Movie distillery plus 6 + HD Pack. Such BDMV discs are roughly synonymous on the PS3 and some Blu Ray players.
What you need fairly quickly in order to benefit from the high Resolutionzu come, it's an HD-capable player, be it in case a minimal HD-Ready, or a full-HDTV, or a corresponding projector.

This agrees well! Because for many people it is quite a financial effort, synonymous for me. Nevertheless, I want the new technology and their quality can not renounce. As a "standard 08-15 Client" in the consumer area, I end with a wine and one eye laughing s.einer FX7 over. And since I am not the actual format whether it is HDV, Standard Definition, AVCHD and Panasonic P2 of is, but the usability of the devices. Because I hate nothing more than a video camera to an everything (and the grotto synonymous nor bad, especially in critical situations in which we as a hobby and amateur filmmakers synonymous very quickly and very often can come ...) - I read very much in this forum and wonder more often about how the opinions of individual users apart and the worst "camp" arise. - Technology is a strong driving force because it supports one's own creativity, which is undisputed. But I can with an old Sony Hi8 of Canon synonymous Or a really cool video to make. Although it has not 1080i ... pfff ... and na? Ergo, it is really of secondary importance, such as super and how great a CameraLink dissolves or not? All of the devices of the current "collection" in the sky lifted or deuced will have one thing in common: just as long as they do not cost upwards s.3500 euro, they are supermühsam to operate. A Focus - Ring zb can surely not be a problem that already existed in a CCD TR705e ... And I LOVE buttons! For each one "fart" in the menu takes time to rise and nerves. Today I have previously mentioned in the often difficult situations such as emerging with one finger (which, no preference how often you wash your hands, leaving grease stains ...) on the touch-screen typing, so that Cam knows what I want to have sharp ... and that helps no super-ulitmativ-I-believe-everything-set STEADYSHOT - the touch on the display can be seen in the telemedicine field, no preference on which stand the "kraxn" is mounted. - All that we are amateur and amateur filmmakers mention must compromise because, as Wolfgang rightly said, one switch can not easily turn. I have a 290er of synonymous Sony (HDD-Cam) daheim whose picture I greatly appreciate, synonymous when it is outdated MPEG2. Never mind! The videos are good! Because the content is good. (at least for me. * gg *)
That is why I personally think so synonymous that these "golden" way should try to find.
I agree as well. This golden path, each for himself can be found. In my case is that I need a CameraLink, the bridge of the old world (SD) to the new (HD) suggests. And since I am now depends not on s.Details like "is really synonymous Camera FullHD?" - Which is synonymous a definition thing. I had the SX5 in his hand and was from the first moment in the thing verknallt.

Because when it comes to something in HD to film, then this camera gives me the opportunity. When I then cut in the end, it is me in my financial situation, where my 900 euros for the SX5 been hurt, no sincere preference. Because some DVDs to the HD material for subsequent cutting to preserve my bar all times ...
