This article is for video producers in most of the video production quality video and audio interest. Mainly concerns the methods of work, video streaming and control of an evil beast compression monster, which all mush.I blank digital video professional video production media in Perth, Western Australia will change to shoot a TV commercial, independent Movies, Video, Business and more.
With the advent of the Internet, I am as a way to video ads for businesses and the quality of Perth and provide happiness in the world. I ran away ONLINE AURA, and drove that develop specifically designed for video transmission.
The problem is that it is aware of the theory of video compression, which met most of them never is a predator was the size of the output to VHS or DVD drive, in which he had said, but never really hurt me. In fact, the power of video compression a big change, but as I have seen the harsh tone digital net in my eyes and listen to cool music was bumblebees.
Over animals and die a horrible time that the experience in the exploration and production of multiple video streaming for local customers, best practices and methods for detecting and learn to edit video streaming. I do not tame the monster is still pressure on the shoulder at every meeting, but I must say that I have learned to keep under control and video compression by only a few scratches here and there.
Be inclusive of these elements Tips and tricks for the fight against this beast next video streaming production.SHOOTING1. Let there be light – to see the start with an obvious and what can be one of the most important qualities of television video.
I know that many things illuminated written recommended in this kind of lighting design (ie – without the slightest). The theory is that by reducing the contrast of the image means you can pack more efficiently, and ends with the picture quality of streaming. It is not entirely correct, because the human understanding of clarity on differences in contrast, is based image can also kontrastia mathematically less pakata create a pixel-pixel level, and an illusion, it is painful to the public.
In general, the standard, to provide the best contrast of sweet and encourages the most important soft light, are trying to describe. Explosives and light camera position when the whole scene is not a positive result, the issue of quality.
The best results have been obtained from sources direction, but there is room for light and other creative approaches.You have to make concessions in the final compression, but usually it is the contrast of the image relative to obtain consent to the adoption. The light is of course a problem, shoot at night can be difficult.
Each grain to cause chaos and increase the monster eats greedily years a little container to shake the individual pixels. You can use the grain to remove the plug-in, but it may be the relaxation of the compressed image and sometimes affect even worse.
Seven ground black levels can sometimes help, and the color saturation, and may also help. When shooting in low light street, try the camera under control, and shutter speed (when the unit a.) the shutter speed is used to pack better in general.
Respondents do I use function keys and a bit player or a background light, a bit before bottling. Video compression to ensure that the fund is relatively stable. Wave with a green screen, and replaces them blurred by more blur or slowly to properly to operate, and maintain a muted background colors compression.
Support for camera movement. – It is clear that a lot of fast camera movement to a higher compression for streaming video demand, however, the various types of traffic data are also a variety of effects .Platform mild compression stroke pretty well, but oddly enough, the same movement forward or rewind, zoom, do not compress well, and usually focuses on how to avoid, if possible.
Cell images tend to suffer as much, if not further stabilized later through programs such as Steady Move. Steadicam images might work well if you are good. Unfortunately, most plans for a Steadicam bit float, while the average person barely unpacked leave both the chassis and a real gun or a title. Closed compressed songs better, of course, it depends on what camera before!
The proposed park – There are many things, compress, compression, while the other things wrong. The water and waves and a beautiful, crystal-clear DVD, video-streaming, but the world collapse. They had a lot of random traffic information.
The same applies to tree leaves in the wind. If you save a conversation or a problem with someone tree the leaves many a windy day, you should take the transition to less traffic in the background.
Of course you want things to be done in the camera to ensure the public interest (which is a summary of a video slide show), but I think the type of structure is in motion. If you move the object into a longer lens to identify and blur the background, which compresses better and clearer for consumers. Since the small screen shots when people go a little close-ups can effective.
VBR art and books .. Compression – you know, that should be done with a variable bit rate video image quality is clearly the standard the CBR (constant bitrate). But to maximize the quality of the video stream requires accounting.
What can use this opportunity with variable bit rate, as I call it container? Imagine if you would like to budget $ 250 a day for a month I buy gifts. Accuracy of the CBR in the world you get $ 250, the first day, and when back the entire game, or not, and finally zero.
The second day of the $ 250 back, and so on. Therefore, the global scientific community, could spend 250 U.S. dollars, because there was no economy in the day. If I see a $ 800 box guitar, now I can not, because you never have the money, and I have settled less than the sum of 200 times. VBR in the world, there is no cost savings.
If you are not spending $ 250 on the first day, and instead of spending $ 150, which means you save $ 100 to spend later means. In fact, you can limit my spending to what you can do that 800 $ to buy guitar in future savings. If you can, make sense in my complex, according to this means that – if one takes VBR I have an idea of how many bits of information that I can play and sales.
Knowing that you do something great movement and a dynamic camera Steadicam shot through a crowd on the street, I know this through a couple of shots blocked little or no traffic has to be balanced. Expenditure is responsible for $ 800 guitar (Steadicam shot) and skimp on other days (such as a shot in the jaw),.
What is the encoding of a video encoder to take into account in the first round of the traffic volume per cage, and the average growth rate of degree of compression for each shot, taking into account the average for the game. Steadicam vaccine is 800 kbps if the pictures are just a 80-100Kbps closure. So the trick is to maximize a number of simple and complex strokes balance of VBR compression.
Has found a good balance between luck and eventually use better compression for better quality of streaming video.5. Progressive Shoot – Shooting for streaming video means that it produces on a computer screen, usually an LCD display.
Process your film is different from a normal TV. I could write three thousand words, the technical differences, but basically saying that the video, progressive scan or interlaced, the perception of images on a screen. Interlaced video (which includes fields), it shows the movement of perfect television, but not traditionally encode movement and video to create objects and the possible impact of contrails.
