Contributing to the file size, in order of importance, are the parameters that set the video bit rate, audio sample frequency, audio bit rate, then frame size.
对文件大小的贡献，按重要性的顺序，依次是视频比特率、音频采样频率、音频比特率，然后是帧速。
With out six combo boxes, we opted to allow the configuration of the video resolution, framerate and bitrate, as well as the audio sample rate and the compression bitrate.
借助这5个组合框，我们选择支持如下配置：视频的分辨率、帧率和比特率，以及视频的采样率和压缩比特率。
In the conventional image or video signal acquisition progress, we need to sample at a high rate first, and then compress the signal.
传统的图像或视频信息获取过程是先进行高速采样，然后再进行信号压缩。
