When Shall We Recode Video?
We need to recode the video frame and audio after editing the MP4 files. Once the encoder, frame rate or code rate get incorrect, we need to recode them. Only when we cut, merge same video, we can skip the recode process.
For example, if we cut video clips from videos taken by same camera and do not need to add subtitle, watermark or compress the videos, we can merge the cut video clips into one without recoding.
