Problems solved by technology
[0003] In the current technology, when non-editing is editing video, there are mobile phones, cameras, and drones. The file formats of the files are 25 frames, 30 frames, 60 frames, etc. Non-editing is editing a variety of different frames There are problems such as low efficiency and unsmooth picture when uploading high-speed files

Embodiment Construction
[0040] In order to have a clearer understanding of the technical features, purposes and effects of the present invention, the specific implementation of the present invention will now be described with reference to the accompanying drawings, but the protection scope of the present invention is not limited to the following description.
[0041] The specific principle flow of this embodiment is as follows:
[0042] Such as figure 1 , a non-coding frame rate conversion method in a field mode, comprising the following steps:
[0043] S1. Collect the frame rate files of the source video and the target video;
[0044] S2. Convert the nth frame of the target video;
[0045] Wherein, the step S2 includes frame rate conversion of the top field and frame rate conversion of the bottom field.
[0046] Said step S2 includes the following sub-steps to the frame rate conversion of the top field of the target frame:
[0047] S2011. Calculate the sequence numbers of the two fields to be re...

The invention discloses a non-editing frame rate conversion method in field mode, comprising the following steps: collecting frame rate files of source video and target video; and calculating the nth frame of the target video. When non-editors are editing videos, there are mobile phones, cameras, and drones. The file formats are 25 frames, 30 frames, 60 frames, etc. When non-editors edited files with different frame rates There are low efficiency and unsmooth pictures. In the process of converting the source video to the target video, this solution proposes a calculation method for the number of target frames in field mode. By calculating the top field and bottom field of the target frame separately, it can achieve more accurate The calculation target frame pixel value. And by calculating the top field and bottom field of the target frame separately, the conversion efficiency is improved.
Description
technical field [0001] The invention relates to the field of high-definition processing, in particular to a non-coding frame rate conversion method in field mode. Background technique [0002] The concept of field originated from TV. Because TV has to overcome the limitation of signal frequency bandwidth, it cannot display one frame of image on the screen at the same time within the refresh time specified by the system. It can only divide the image into two half-width images. Appeared one after another, due to the fast refresh rate, it is invisible to the naked eye. Ordinary TVs use interlaced scanning. The interlaced scanning method is to divide a frame of TV picture into two scans of odd field and even field. For the first time, the odd field composed of all odd lines such as 1, 3, 5, 7, etc. is scanned, and for the second time, the even field composed of all even lines such as 2, 4, 6, 8, etc. is scanned; the even field field should be It should be the top field, and t...
