Because adding the rotation field will shorten video time, it will greatly affect the author’s modification of video after the clip.I hope the rotation can be superimposed on top without affecting the true video time.It’s like a filter.Moreover, the transfer can be a file in the installation directory. As long as the transfer file is added in the installation directory, the software will display the new transfer field in real time and improve the extension of the transfer field
Your English is not understandable. Use the English names of actual UI elements. You say “rotation” but I think you are talking about Speed from Properties. There is a technical reason Speed is not a Filter.
I’m sorry, I may have made a mistake.I mean, hopefully the Transitions can be like a filter, and every time you add the Transitions , it doesn’t shorten the length of video。Because I often modify the clip Transitions field, every time I modify the previous clip Transitions field, the video time will be reduced and there will be more space。It really bothers my editing

Could the “Ripple All Tracks” option in Shotcut be useful for you in this situation?
i can‘t find“Ripple All Track”options。。where it is
i try Ripple All Track,but it’s going to change the total video time。i do not wanna change total video time when i add transition
You do not always need to drag-n-drop/move a clip to make a transition. If you have trimmed your clip so there is extra footage before the in point or after the out point, then you can drag the left or right edge of the clip over a neighboring clip.
