I really think the new 3.0 video editor is not easy to use, the operation logic is not as good as the old version 2.9, especially in the addition of key frames, as well as between key frames, it is difficult to operate, I hope you can make some improvements
@Lee99 , if the tutorial is not that helpful to you after all, or in case you still wish to go back, then feel free to acquire a previous release through this page here.
