3D stereo movie suffix format introduction

3D stereo video format introduction

3D stereoscopic video format is mainly divided into two types, we often refer to it as true 3D and pseudo 3D, respectively, explained below, also divided into A, B is two, A is a stereo movie, and B is a complementary color film. You can apply the above common name, but it is not recommended.

A: Stereo movie. Whether it is left and right separation, left and right synthesis, up and down synthesis, interlaced format, you can use the player software such as Stereoscopic Player to play dual screen output, cross screen, left and right screen, up and down screen, interlaced screen, and play into red, blue, green and yellow. The display mode such as blue can be said to be all display schemes involving stereoscopic, which is commonly known as true 3D. So what are the advantages and disadvantages of these formats? Let's take a closer look. 1, left and right separation: Left and right separation is also called two-way video, ** two-way video, in principle, the effect is combined with the left and right, the upper and lower synthesis effects are the same, in fact, the left and right separation format is currently recognized as the best polarized stereo movie, naturally it has The main reasons are as follows: left and right separate video can be added to the audio track file AC3, want to change Mandarin, Cantonese, English, as long as there are ** audio tracks can be easily added, but now AC35. 1 channel The soundtrack is everywhere, so that the left and right separated stereo movies can easily practice the left and right main sounds, and also practice the sound, surround sound, subwoofer, and even the 7.1 channel is not a dream, become a real 4D level commercial effect, around The format of the short film also supports continuous broadcast, if the right and left adjustment is more convenient to change the name, while supporting the video settings, fast and convenient, the current separation of the best film up to 1080 HD, is currently the best, most popular commercial stereo video format, The only shortcoming of high-definition left-right separation is that the computer host and graphics card are more demanding and larger.

2, left and right synthesis:

Left and right synthesis combines the left and right directions into a video polarization format, and also synthesizes the audio track. The left and right synthesized polarized movies are generally wider than the non-standard format ( Not necessarily non-standard compression), so many merchants lie to outsiders with resolution (such as 1280X480 resolution, some businesses still call 720 HD, 720 HD resolution is 1280X720, and the actual resolution of 1280X480 left and right synthetic format is only 640X480 , the resolution of the DVD is lower than the resolution of the DVD, and the resolution of the left and right synthetic resolution is 2, but the height is constant. The advantage of the left and right format is: the most convenient to see the stereo, even if it is used in the storm Play can also use the screen mirror or cross-eyed ** directly to see high-quality stereo, left and right format short film can also be broadcast, the disadvantage is that can not be added to the ** 5.1 audio AC3, video format and standard, high-definition format on the computer Host and graphics cards are more demanding.

3, top and bottom format:

The upper and lower formats are basically the same as the left and right formats. It is also a non-standard aspect ratio video format. The upper and lower formats are discharged up and down. The upper and lower formats are originally generated. Because of the glorious era of red mesh glasses at that time, the popular widescreen 16:9 stereoscopic movie was made up and down format, and the 2D playback has a larger viewing area. The true resolution algorithm of the upper and lower formats is the same width. The height is divided by 2, the main advantage of the upper and lower format is: the upper and lower format is also one of the ** polarization formats, can be made into the highest 1080 high-definition format, convenient for red network viewing, short film can be broadcast, can also support video settings once and for all, shortcomings It is unable to join the **5.1 audio track AC3, HD high-definition format requires higher computer and graphics card.

4, progressive scan interlaced format:

This is a two-ghost interlaced format, is a more scientific, more complex polarization stereo format, this scanning method The interlaced format uses de-interlacing technology. The interlaced format is also the only aspect ratio standard on the market. The video aspect ratio is also the standard polarization format. It can be made into a standard DVD for convenient signal storage, so the interlaced stereoscopic movie is generated. It is impossible to think of the left and right format to make a DVD, unless the red and blue movies with very poor color are incomparable; the most deadly weakness of the progressive scan interlaced format is that the MPG de-interlacing technology is still used, and the HD era faces Great challenges and even elimination, the 720 or more interlace almost disappeared, why, the host is the reason for the current high-definition compression technology and volume, but currently the progressive scan interlaced format is better than the interlaced resolution, progressive scan The interlaced format is a standardized SD format. The resolution algorithm is still the same as the original resolution, but after converting to the left and right format, the original image is not as good as the original. About good format, the main reason is de-interlaced frame plus field of information technology such compression, interlaced format on the computer do not ask, you can not even play. The disadvantage is that it is difficult for novices to play into dual output, mainly because the decoding is not supported or not set, and even non-editors may not know how to separate the interlaced format into left and right, which makes people laugh and cry.

5, interlaced interlaced format:

This is a stripe interlaced format for vertical interlaced interlaced scanning, which is a movie that looks directly at a stereoscopic frame in an interlaced field. In fact, this movie is also made into a standard DVD format. The interlaced 3D display connected with a DVD player can also be viewed at a certain resolution, but since the interlaced scanning is older technology, it is not available in the HD era. The recognition of the settings, this interlaced mode of high-definition film is not uncommon, but can not say no, the latest avatar has also appeared this interlaced interlaced 720 trailer, the resolution algorithm is the same width, height divided by 2, The image is not deformed, it is a scientific storage format, and may also become the next generation radio channel stereo channel signal standard. The advantage of interlaced scanning is that it is not demanding on the computer, and it is better to play into two channels without decoding. Can practice continuous broadcast, mixed broadcast and video settings, the disadvantage is that the resolution is lower, the effect of 480P is not as good as the red and blue of HD, support ** audio track except the left and right separate format I naturally do not mentioned. Want to convert to the left and right format, is not a general expert, unless you use professional software.

B: Complementary color film. Red, blue, red, yellow, green and other complementary color films can not be played into left and right pictures, up and down pictures and interlaced pictures, can only be played with ordinary playback software 2D playback or Stereoscopic Player into 2D mode and wear corresponding stereo glasses . 1, green red format: (green magenta format) Green red format should actually be called green magenta format, this stereo movie is more popular in the past two years, the more common film has a heart tour, my bloody Valentine's Day, Caroline (Ghost Mother) waits for the three-dimensional film, I believe it will become the new favorite of complementary color movies, mainly because the picture is softer than the red and blue (red and blue) movies, the red display is more vivid, because green and magenta are complementary Color, these two complementary colors are not dark, and can display soft details.

2, red and blue format (red and blue format):

The red and blue format is actually the official name of the red and blue format, which is also the most widely used complementary color format, which is what we say The red-green format, which mainly stores the left information in red, and the right information in cyan. Of course, the right information contains green and blue information, and the right information is rich. Because everyone calls it red and blue format, not I said that I am indiscriminate. Of course, I am also an expert in this field. I have not blamed everyone for the meaning. I don’t know when it started. We called the red and blue movie a red and blue movie, red and blue glasses. I just want to give it here. Everyone corrects the name of science. The red-green movie is not extraordinary. Compared with red and blue, its filter color is not so dark. The filter color can be bigger and stronger. The disadvantages are still there. Red is the primary color. One of the key colors of the natural world, the left image as a primary color storage, of course, looked very dizzy, anyway, the color is dizzy, but the red and green complementary color format gives the brain a strong sense of three-dimensional This is also the green product The movie excels.

3, red and green format: red and green format is one of the left and right stereo movie formats of red channel and green channel, red channel stores left information, green channel stores right information, green contains ** and The blue combination information, the right channel is richer than the left channel information, and the two eyes are reflected to the brain after viewing. The red and green mixture is close to black, and the restoration is close to the original stereoscopic scene. The red and blue movies are not worse than the red and green movies. How much, mainly green will be darker than cyan, filter color compatibility is not more cyan, so far less popular.
