Coquettish Rebirth

In fact, the post-production period is not long, after all, it is not relying on post-production computer special effects to make huge explosions, such as heaven and earth.What the post-production really needs to do is to extract the image layer of each frame, and then combine it with the scene of the NBA China game.For example, those materials shot at the scene of the nba China game are actually only used as one of the materials. After all, the scene cannot be called to stop or repeated shooting. Although the overall playing routine is still in accordance with the previous settings, there will be various Unexpectedly, there will be places where the performance is not good and the viewing is not very good, so you need other materials to make up for it.Then, a few days earlier, in the tennis center, the young players had already filmed the "nba China game halftime performance" scene that will appear in the TV series in advance.

That's right, in fact, the scene of the real young players playing an exhibition game was filmed in advance, and they came to this venue specially during the filming, spread green cloth on the seats beside the court, and then let the young players play on the court.The things shot in this way can quickly remove the pictures of the auditorium, and then synthesize the pictures of the audience taken in the real NBA China game!Speaking of which, why did you come to this field to let the young players play?Why can't you play in other indoor venues?Because of the lights!Whether the post-production video synthesis can be seen as true or false depends on whether the lighting is coordinated or not!And to be honest, lighting is really important for film and television, and many times the film and television screens look good or not, and even the actors look good or not.It all has a lot to do with lighting!Or why did the lighting engineer in Hong Kong used to be called the Lord of Light?It's just that you can't afford to offend, or even want to please!

Why do you say that?Because to put it simply, why do Japanese geisha paint their faces so white that they look like female ghosts?This is because they do their make-up according to the lighting conditions of previous performances - in the past, Japanese geisha did not perform during the day.Instead, at night, in the home of a nobleman, a daimyo, performing under candlelight conditions.And candlelight is actually yellowish in color, so if a woman's face makeup is painted with a normal pale complexion, then she looks like a yellow-faced woman in a candlelight environment!So in order to look beautiful in the candlelight environment, the result is to turn the face pale!And such a make-up mode, of course, looks very weird under the illumination of various modern daylight and various electric light sources.

From this point of view.You can see the impact of lighting on visual effects.Likewise, if an actress offends the gaffer, the gaffer can do something about it a little bit.It can make the actress's face look a little yellow in the film, like a yellow-faced woman, or a little sickly pale!No matter how the effect is, it can be said that it is at the level of a lighting engineer!Although it is said that the director will want the best effect, the actress must have a big card.Otherwise, there is no need to fall out with the lighting engineer.So it is considered polite to the lighting engineer!

Similarly, lighting is very important for actresses, and lighting is also very important for visual effects.In various national films outside of Hollywood in the 8090's and [-]'s, scenes with special effects are very easy to see fake!why?Because back then, except for Hollywood, computers were not used for special effects editing. Even if computers were used, because the practitioners were not as good as Hollywood, the actually pasted pictures and the background lighting were different!This makes it look fake!For example, a background building explodes in a dark night.Then the scene where the hero and the heroine run away, should have been the camera just in time to capture the faces of the hero and heroine and the exploding fireball behind them.But some countries do not allow actors and actresses to actually film against the backdrop of the explosion.It is divided into indoor shooting of the faces of the male and female protagonists and outdoor shooting of explosion scenes, and then combined together.However, if the lighting engineer is not good enough when shooting the faces of the male and female protagonists indoors, if the powerful light source brought by the explosion of the background and the lighting requirements that the male and female protagonists must have faces so that people can see clearly, then then It's easy to see that it's fake!

For example, if you want to simulate the reality as much as possible and make the front lights of the hero and heroine too weak, it will easily lead to the actual shooting effect that the faces of the hero and heroine are all black and you can’t see clearly—in fact, if two people escape In the case of an explosion scene, especially when the light is not good, the explosion is of course bright, and then the person running away with the explosion on his back is not backlit all at once?Isn't it equal to being black all of a sudden?This is the so-called "darkness under the lamp"!But this is true and true, but it is not good-looking-because the male and female protagonists are all stars, even if they are not stars, the audience wants to see their faces and expressions!So this time it can't be real!

It's like when shooting an indoor scene at night, you want to shoot the so-called scene after the lights are turned off. Logically speaking, it should be pitch black!In many cases, the actors even acted like black people who couldn't see their fingers!But you really can't be so dark when you're filming, otherwise the audience will look at you?So even if it is said to be a dark night where you can't see your fingers, the lights are actually on!It's still better to make it brighter than the moonlight, at least so that the audience can clearly see the faces and movements of the actors!

And back to the topic of making special effects, in the case of such an explosion background, it is necessary to make the light of the explosion look very real, and at the same time make the faces of the actors clear, this skill is beyond the reach of ordinary people!Therefore, if the lights on the faces of the actors and actresses are brightened a little, it will look strange, making the audience feel that it does not conform to the physical principle, and it will feel fake all at once!And if the lighting is too dim, and the faces of the actors and actresses cannot be seen clearly, this is of course even worse!So what to do?Not to mention actors from other countries, even many lighting engineers in Hollywood can't do this well!It’s just that people in Hollywood will be tricky. They may mainly focus on the explosion itself in the scene of the explosion, and then the big fireball behind the real actors and actresses may appear in just one second, and then during this second, the faces of the actors and actresses It was relatively dark but the outlines could still be seen clearly, and then they asked the actors and actresses to look back at the explosion, so "by" the light source of the explosion, wouldn't the faces of the actors and actresses be clear?

Speaking of the special effects of the NBA China Games, since it is necessary to do video editing and synthesis, of course, we must try our best to match the background and the lighting of the young players, so that the effect can be as realistic as possible.But to achieve such an effect, it is really difficult and labor-intensive to simulate exactly the same lighting as in the NBA China game just in a studio or other indoor basketball courts!And in this way, it is actually better to come here a few days in advance and shoot directly on the spot!Anyway, there were no activities or competitions in this tennis center a few days in advance, and the stadium was also empty, and we also rented such a venue later, and we also have business contacts with the tennis center. In the case of foreign audiences, and there is no on-site garbage, it is really no problem to come to the scene at a relatively cheap price to light up the scene and shoot the scene!

The post-production of this video is not difficult to actually produce.First of all, let’s talk about the content of the design, such as the game played by young players surrounded by green cloth in advance, that is, the background with a specific color can be directly deducted through professional post-production software!There is no need to manually detach frame by frame, and the computer can automatically batch it up!So otherwise, when shooting various videos at home and abroad, blue cloth or green cloth is basically used where special effects are needed. Such a simple monochromatic background is the easiest to buckle and the most efficient!And there is another more efficient method in post-production, which is to separate the fixed background from the moving pixels. For example, if you shoot a person walking on the open snow, you can combine the snow background with the walking Even if the snow background is not completely pure white, as long as there is no wind and no movement in the background, it will be fine!And the most complicated scene is the scene where the background and the characters also move, especially when the colors are more complicated. For example, in the nba China game, the audience are all living people and can move. At least they will turn their heads according to the situation on the field. Twist away, there will be various expressions, coupled with the activities of the young athletes, it is really troublesome to deduce the characters and the background frame by frame by hand!

As for the method Jia Hongjian and the others adopted, that is to combine the two aspects of materials. On the one hand, they first filmed qualified materials in advance, and let the young players play the best viewing materials under the green cloth background, which is most in line with the needs of TV dramas. The game is used as a material reserve.Then let the young players go to the midfield of the real nba China game to play according to the prescribed routines. In this way, they can be used directly when they perform well on the field!As for the places where the performance is not the same as the script, or the places that are less enjoyable to watch, then edit the shots that can be edited with the shots taken in advance. Can also fool the past.As for player mistakes or something, then use the method of post-production video synthesis to pull out the audience in the background, and then combine it with the playing scenes shot by the young players in advance, that's it!

And such a result, that is, within a week, the post-production was successful!That is to say, a week after the NBA China Game, such a TV series can actually be sold and ready to be broadcast on TV stations! (To be continued..)
