HI DGP23,
More information on the clips being used, the capability of the computer you're editing with and maybe the layout of the project in the edit workspace will help here.
1. What have you got the Preview player set at?
2. Are you using Shadow Edit Files?
3. using Media Info can you provide the data on the video.
4. Diagnostic and Screenshot of the edit Workspace please as well.
