@William-Porter Hi,

I'm trying to pull a movie clip from a project by deleting a section of the video before the scenes to keep and after the scenes to keep.

At the bottom of the preview window there are options - Remove start etc.. But the easiest wat is to place the cursor where you want to remove the start & press Z on the keyboard. To cut the clip where the cursor is press T on the keyboard then click on the unwanted part & click Delete on the keyboard (or click the bin/delete button at the bottom of the preview window). & to remove the end from where the cursor is press U on the keyboard. (you can also just drag the ends of the object on the timeline to make it shorter or back to the length it was after you've trimmed some off)

Also, how do I reduce the project timeline after the scenes are deleted.

You can simply click & drag the remaining scene after cutting off the start & end, or at the bottom of the preview are 'Mouse modes', these are ripple options, ie if you are in Single mouse mode after you cut the start nothing happens, in Mouse mode for Single track & All tracks after you remove the start the clip to the right of the cursor will snap to the left closing the gap.

PS. There are Tutorials at the top of this page, most are from earlier versions of Magix but the information will still be relevant as the program has hardly changed, this is the link to Movie Studio tutorials https://www.magix.info/us/video-tutorials/movie-studio/
