After that, move the red marker to the end of the scene, and repeat this again to cut the video into several fragments. If you want to cut off the unwanted parts, right click the video and choose "Delete".

2. Join MP4 Video

To join several MP4 video files into one, you just need to place all the video files on the timeline, adjust the order and hit "Create" to export it.

If you want to make the joined videos look like a really intact movie, just add transitions between clips for smooth change from one to next. To do this, click "Transition" tab on the main screen. Then drag the effect you like to the timeline to apply. 

If you don't want to choose the transition one by one, let the software choose the transition randomly by right clicking and selecting "Random to All" option.
