The clarity of video transmission depends on the following factors.

Set according to the following figure:

1. The default configuration is "AVC high quality and size". On this basis, it is further revised.

2, video coding, choose AVC.

3. The screen size is the resolution. Select according to the original screen size. Not smaller than the original painting.

4, bit rate, the bigger the better. The maximum format factory is 16000, which is enough in most cases.

According to the above parameters, it must be clear.

The way to reduce the size of video files such as avi is to reduce the video bit rate or video resolution, which can be realized by video format conversion software, such as format factory. See the figure below:

Bit rate, the popular understanding is the sampling rate. The larger the sampling rate per unit time, the higher the accuracy, and the closer the processed file is to the original file, but the file volume is proportional to the sampling rate. The higher the bit rate, the larger the file and the better the video quality. The lower the bit rate, the smaller the file, but the worse the video quality.

Video resolution, that is, the size of video, is the width and height of video pixels. The higher the resolution, the higher the video pixels, but the larger the video file, the smaller the resolution, the lower the video pixels and the smaller the file.

Therefore, the reduction of video file capacity is at the expense of video quality.
