Embodiment Construction
[0029] In order to describe the technical content, structural features, achieved goals and effects of the present invention in detail, the following will be described in detail in conjunction with the embodiments and accompanying drawings.
[0030] see figure 1 , the present invention provides a method for making dynamic three-dimensional floating subtitles, comprising the following steps,
[0031] Utilize source subtitle image to make the subtitle video file of a 2D transparent effect, and described 2D subtitle video file is transformed into two identical video files;
[0032] Calculate the picture parallax of each pixel scale of the two video files according to the depth of field index;
[0033] Setting the offset between the two video files according to the picture parallax;
[0034] Perform compression processing on the two video files, and perform rendering and merging processing on the compressed two video files.
[0035] Through the description of the above steps, it...

The invention discloses a production method and a production device for dynamic three-dimensional floating caption. The production method for the dynamic three-dimensional floating caption comprises the following steps of: producing a caption video file with a two-dimensional (2D) transparent effect by utilizing a source caption image, and converting the 2D caption video file into two video files which are the same; calculating the picture parallax of each pixel scale of the two video files according to a depth of field index; setting offset between the two video files according to the picture parallax; and compressing the two video files, and rendering and combining the two compressed video files. According to the method and the device, a picture set is converted into a dynamic three-dimensional floating caption effect, and the unified conversion of a large batch of video files is possible; and the method and the device can be widely applied to the video production industries of KTV entertainment, advertisement, media communication and the like.
Description
technical field [0001] The invention relates to the field of multimedia technology, in particular to a method and device for making dynamic three-dimensional floating subtitles. Background technique [0002] 3D film and television production and 3D theater construction have been included in the key planning projects of the "Twelfth Five-Year Plan" of radio and television. It is estimated that the annual growth rate of 3D TV will exceed 80% in the next five years, so the content production of three-dimensional digital entertainment will have a lot of room for development. Autodesk's 3d Max, Maya, Softimage, etc. are all familiar 3D design tools in the design industry. They have designed classic stereoscopic image works. The production method of quickly converting into 3D standard format and attaching 3D subtitle sources to 2D works to produce stereoscopic special effects came into being. However, the 3D subtitle production methods currently on the market usually use the 3D s...
