[Feature request]: set the speed of the two videos to align

Suggestion

Dear developer, hello!
Thank you very much for writing such an excellent software, which helps me improve the efficiency of watching online classes. Here are some suggestions for the software: There are two videos in the recording of the teacher's lecture in our school. One video records the teacher and the blackboard behind the teacher, and the other video is the display screen of the computer displaying the ppt on the big screen. Therefore, I need to play these two videos at the same time and check the time synchronization, so that I can watch the recorded class well. But I found that if I adjust the speed of one video in the software, the speed of the other video will not be adjusted synchronously, resulting in that when I play, even if I set it to synchronize by time, if the speed of the two videos is not adjusted synchronously, the timestamps of the two videos are still not aligned. Could you please add a function to set the speed alignment of the two videos?
Thank you very much!
