CPU usage during video preview is insane - i.e. unusable.

Not exactly sure what is happening. To give context, I'm attempting to see if this software is worth using. When I first started using it, I recorded a test clip as well as got some music to add over it. When I added the music to the timeline, no issues arose. I could even clip it and play it. However, once I added a video, the entire thing became unusable freezing more than once. I'm not entirely sure what is happening, however, I have recorded a few clips so that you can view it yourself. NOTE: I have recorded it in low quality to not cause the software to be hit hard.

Proof that the clip that I was editing was not corrupt in anyway:

Figured out, if I turn off experimental mode, it resolves this issue.
