Newsmeldung von slashCAM:Hier geht es zur Newsmeldung: JVC synonymous faster signal processor for consumer camcorder
Antwort von NEEL:
S.sich would be good news, if the label is not "JVC" would. Until now, JVC has almost always managed to, with a great innovation as the first to be on the market, but versemmeln to the specific design so that the cam is practically useless ... . Nevertheless - the future is 4K!!
Antwort von WoWu:
Only with a new processing dissolve the real problems that happen so s.der optical implementation, not synonymous.
Antwort von deti:
Only with a new processing dissolve the real problems that happen so s.der optical implementation, not synonymous. Yes, but perhaps the future lies in the ability synonymous to guess the intentions of the camera operator and then a beautiful picture of them as possible to render artificial ;-)

Well, maybe that JVC sells processors synonymous with appropriate programming to Canon or Nikon, so the times of full frame sensors based on a reasonable 1080 he put together Downskaling. To some extent it has been so synonymous with the HM-400 can monitor (in this case, however, on the basis of small sensors, but with 10 megapixels)
Antwort von WoWu:
Only the (current) full-frame sensor makes precisely the problem.
And 4k is such a great slogan. The 4K projectors neither forward nor are they in the foreseeable future so cheap, that is a set of ordinary consumers. And even 4k is still a problem and as long as you get the picture somewhere on the 1920 must be the problems are not small.
It changes nothing synonymous with so much processing.
Deti is right, maybe we get a lot of convenience, but it is no better pictures.
Full size is good and beautiful, but as long as None hergeht and redesigned the sensor and equips him with good-sized pixels and donated the extra transistor synonymous for GS will change anything significantly. JVC also nothing with a great processing.
Antwort von domain:
Some time ago I once an example of a simple quantized scaling shown in Photoshop (horrible transitions and stages in nearly horizontal lines) and in Comparison to a bi-cubic, in which is really each pixel included in an algorithm and charged and is indeed a unique super smooth anti-aliasing effect brings with itself. At the most you can no longer remember WoWu?
I need to tell None, that a perfect downscaling in Photoshop by software (firmware =) would not be possible.
Antwort von WoWu:
Shots!
Problem is the Alisaing!
We are talking here about the video recording and besides, we still talk about real time.
Looking at the process time distribution in the "primarity processing" on, you get a quick impression of what already today to shorten the process leads.
Edges are no longer charged today by the whole picture but only parts s.bewegten etc.etc.
Thus, a rendering process may well lead to nice results, but not in real time.
What's more, that all the problem cases of lens / sensor are not eliminated. They are smeared only by the Bildverkeinerung or covered.
Image reduction is not an option otherwise the camera manufacturers have long been synonymous accessed it, as you can imagine, know that the development engineers Photoshop synonymous.
Antwort von domain:
I believe, however synonymous.
Accordingly, it is high time that the Einzelbilkompression including intelligent Downscalingprozesse that can take place synonymous in real time, is being rediscovered. AVCHD Mpeg4 and Mpeg2 much more than recording video codec designed for DSLRs not suitable, more like Mjpeg with its single image compression.

Yes, but perhaps the future lies in the ability synonymous to guess the intentions of the camera operator and then a beautiful picture of them as possible to render artificial ;-)
Deti Right. 4k will not help if the man behind the camera has no idea how to look good pictures. Better to SD and good, impressive images than 4k with some boring stuff that exists only in special effects, 3D and focus shifts at every opportunity.
Antwort von WoWu:
@ Domain
Well, I agree not entirely consistent, because the artifacts mentioned in DSLR video as negatively significant, take place well before the data reduction and to remain the choice of data reduction is directly dependent on the desired image format and the resulting Request s.die storage medium is.
Completely apart from the fact that there is currently no better motion estimation within a data reduction indicates that seems synonymous acceptable price.
I do not think any filmmaker would storage medium for video cameras in the price of 600EUR Dimensions of 1000 EUR and accept more, "counter to come" only to the data reduction.
No, no, that ratio is true. I admit it would be synonymous to the consumer to enjoy, he came out of the swamp and AVCHD would benefit of a few tools to keep the profile better prepared for him.
Yes it is and ultimately find the synonymous in other AVC shall apply. But the companies are again making "piecemeal".
But as long as the button lenses provide the camcorder so lousy performance, you need to think about anyway. Just as above in such combinations as DSRL that need to be made artificially, blurred, so that the "mismatch" Lens / sensor is smeared.
While such elementary problems are not corrected, you need neither a new Processing, yet einneues reduction method. Quite the contrary. The dependence of the reduction process of the predetermined image quality is now so well known.
Images come forward so pure works better, the reduction procedure due to its nature is not only faster but better synonymous.
So it is with making the existing lot more if you would remove even the cause of all evil.
I would personally even the 2 / 3 "environment significantly better than those stirring with the sharpness in the Picture. Moreover, there is a huge choice of high-quality broadcast lenses, where you are mechanical implementation should worry more synonymous.
Therefore, for me would be another possible solution that is recycled, the whole gimmick with the depth of focus for the video area to manageable levels.
Antwort von domain:
I think WoWu that one views the entire matter should be regarded from a historical perspective. In 35 or 16mm shooting already impressive hold a single image so much information that they are below the aspects of time and today's computer was synonymous not specifically addressed in the motion picture and is. Hence the enormous efforts to diverse data reduction, which is so synonymous managed super intelligent and effective.
But these efforts are not always apply and may be necessary. Man returns to single images and their more or less strong, so actually return less severe compression. There are already many indicators and it is interesting to pursue these efforts.
Antwort von WoWu:
I think it will be a combination, because it is still not clear why one should transfer the same data of Picture of Picture several times.
So the way back I do not see. But something like AVC-I, is reduced in the so synonymous in the images perfectly, but it is really just redundant.
So something like JPEG is from a variety of reasons, not really desirable and will not come back probably synonymous.
Antwort von domain:
For me there is a clear difference between recording and playback. When are the Recording is nothing better than a permanent redundancy, in each picture a lot of information of the previous image are repeated for security reasons.
When playing something completely different and the more relaxed you can see, there would be a repetition of redundant data really pointless.
Antwort von WoWu:
Well, only with the recording you put synonymous fixed unfortunately your data rate and constantly with 3Gbit/sec to handle real-time happens to be no really good alternative and when the camcorder owner then synonymous still have to take the cost, makes video, of course, no real more fun.
No, no, that's quite pk, as it is.
The camcorder and the photo-snapping are already so bad of the acquisition ago, by a better codec anyway does not change and the prosumers have I-frame based codecs and those who are using yet MPEG2, will soon get better, at the latest, when p50 called for better quality, because there listening to the flagpole for MPEG 2 on rather abruptly.
So really there is everything, if the optical translation, back to the sensor would be better. Synonymous then the SNR will be better, the filling factors are synonymous so lush and again make the possibilities for more time with the mechanisms.
If you do not then the whole friemeln with camera lenses must, but synonymous with, the parameters governing the requirements produced broadcast video lenses, then it's all good.
It just lacks only the right sensor, which is not just borrowed from the photographic technique but is present in an adapted version .... I am sure, will be.
Pana has indicated a year ago, the MOS sensors they use in the 300ern, synonymous in 2 / 3 "produce. Now they have pushed forward a photo sensor, presumably work to the drifting of the India's market for the first time counter, but the Brpadcaster they have therefore not served.
So let's see, because I can do with such a fuzzy box no real contributions to the genre.
