Forest and the teleplay that the person such as Cai Zhuoyan acts the leading role " motor-driven army " had left in the line on original video platform sow, at present already free head sow 4 collect. This alarm the consistent style of this type theatrical work that bandit drama holds Hong Kong respect to manufacture, rhythm is lively, alarm bandit struggle is intense, danger is as unripe as annulus etc. Nevertheless, to this " motor-driven army " will tell, truly notable is, its gut content cannot computer end is broadcasted.
Why cannot broadcast on computer screen about this teleplay, the explanation that platform respect gives out is: Because of copyright reason. And at present " motor-driven army " can upgrade in platform respect only broadcast on the APP of version, and this APP also can to load is in mobile phone or Pad inside. Can move only end broadcasts, cannot computer end is broadcasted, " motor-driven army " what cat be bored with hiding after all? Be really " copyright reason " ?
Actually, this is " motor-driven army " the technology upgrades. What this teleplay uses is the video after HDR upgrades films mode. In light of the introduction that gives out according to platform respect, its camera lens realized every second 50 frame fluctuate. And, HDR films after upgrading, the most apparent change is, the picture susceptibility contrast of video is more sharp. These apparent change, it is partial computer screen can not be reflected come out.
Say the problem of 50 frame first. Will read a statement with relatively at present accepted academia first: When the object is moving quickly, what person eye institute sees is video after disappearing, person eye still can continue to withhold its the image that video 1/24 second controls, this kind of phenomenon is called visual of short duration takes an appearance. It is a kind of quality that person eye has. When person eye watchs an object, into resemble going up at retina, input person head by optic nerve, find an object picture. But move when the object when going, optic nerve won't disappear instantly to the impression of the object, and the time that wants left and right sides of continuance 1/24 second, this kind of property of person eye is called " the visual of short duration of the eye stays " .
Be based on this learning acknowledge, at present theatrical work of general movie and TV films, with every second still 24 pieces of pictures are basic principle. This namely the 24 frame that we say. Nevertheless, the last few years, as network game arisen, every second the picture of 24 frame has been replaced, 30 frame, 60 frame and the video picture of 120 frame begin to appear.
Compare typical case, be Li An's director " those who compare Li Linen is medium field war " , on video picture, realized every second 120 frame. When China was shown 2016, partial cinema realized the picture of 120 frame to show. Although say person eye can identify every second only 24 pieces of dynamic pictures, but actually, if every second realizes 120 frame, criterion the picture is more full and clear.
To forest of and Cai Zhuoyan this " motor-driven army " will tell, it realized the picture that every second leaves on 50 frame. This picture, do not have a body to come out now really between partial computer screen. But, between present smartphone terminal, can present a result. And on the other hand, be HDR video technology upgrade problem. This also is a revolution of drama of prospective movie and TV.
HDR vision technology, a what thing be after all? Say first simple, upgrade through the technology namely, let image and video present contrast of more high grade light and shade, be close to Yu Zhen fact more. Next, last academic views:
The brightness of actual and true existence is poor, namely the brightest object brightness, with the darkest object brightness more square than be 8 times of 10, and the scope that human eye can see is square left and right sides 5 of 10, but general monitor, camera can be denotive the brightness that only 256 kinds differ.
But we can take a few pieces of pictures more, 2 pieces, 3 pieces... even a few pieces, the exposure of these photographs is ordinal increase, a lot of friends should be OK think of, as the accretion of photograph exposure, the photograph will be ordinal brighten, change a kind of point of view, denotive detail meets photograph place to be changed to shadow by bright place.
According to the principle above, if we pursue what camera films a lot of pieces a synthesis, the quantitative class of result picture is 16 times of 2 commonly square more even.
HDR vision upgrades, fall on 50 frame add a brick to add tile, formed " motor-driven army " decline computer carries screen to broadcast, change a smartphone to the main reason that end broadcasts. Will tell with the simplest word, it is the video of this teleplay, the picture that every second gives out is more, the susceptibility contrast of every pieces of picture is sharper, more adjacent and true. This " motor-driven army " play a way newly, with the Li An a few years ago " those who compare Li Linen is medium field war " different in approach but equally satisfactory in result.
Of this kind of technology upgrade, what can bring filmgoer to watch a movie is brand-new experience. And brand-new experience backside, the industry that will be two respects upgrades. The first, be drama of movie and TV film upgrade. After, as HDR and taller frame intervene, film equipment will be innovated actively, those offer the small mill of equipment for drama of movie and TV, the business will be more bad to was done. The replacement of new facility, will look at present, charge does not poor. The 2nd, be whole computer screen change, must want to satisfy this more advanced broadcast definition to just go.
" motor-driven army " the industry that intervening movie and TV goes stealthily upgrades, this is the business that deserves person of the same trades to notice.
