Problems solved by technology

Post-production is time-consuming and laborious, and requires computer hardware support and the need to purchase professional software
Generally speaking, video editing and production cannot be carried out immediately after shooting, especially for ordinary household DVD cameras, it is usually impossible to carry a computer for on-site editing when shooting. The camera is imported into the computer, and the DVD video that has been shot is edited on the computer, which causes inconvenience to the user
And the software to process the video is also expensive, which increases the cost of the user

Abstract

The invention relates to a method for appending sub-pictures for DVD videos before the end of a DVD disc, which comprises the following steps: determining the sub-pictures (editing texts, setting colors, and the like); converting bitmap data of the sub-pictures; generating an SPU (Sub-Picture Unit); and reusing the SPU and the DVD videos. The method is convenient for users to operate and use without installing and learning professional video processing software, thereby saving the cost and the time.

Description

technical field [0001] The invention relates to a method for processing DVD visual special effects, in particular to a method for adding sub-pictures before the finalization of DVD discs. Background technique [0002] Currently, commonly used DVD camcorders use DVD-R / -RW discs to record DVD-Video format videos. After the video recording is completed, the disc needs to be finalized to be compatible with the DVD-ROM format. After the disc is finalized, the contents of the disc cannot be modified. Among the two common disk methods, DVD-R supports incremental writing, and DVD-RW supports limited overwriting. Both methods cannot support modifying data areas that have already been written. [0003] Using the sub-picture specification defined by the DVD-Video format, sub-pictures can be added to DVD video so that it has visual effects such as photo frames and memos, so as to make DVD video more beautiful or easier to watch, which is very important for DVD video processing. A proc...
