I completely understand your interest in saving slideshows in MP4 format, complete with transitions and music. My experience in video editing has often led me to seek similar capabilities. It's about achieving functionality and the creative vision you have in mind, particularly with the proper video resolution and frame rates.
Through my experiences, I've learned that choosing
video editing software is crucial. It needs to be both feature-rich and user-friendly. For all my video editing projects, I've consistently used Movavi. It's been a significant asset for me, particularly for tasks like creating MP4 slideshows. Its ability to adjust resolution and fps meets the requirements you're discussing.
