Green and black lightning flashes on imported video.

[Sarah5D22]

Good morning

We are new to video editing using Premier Pro, however after following a tutorial we were able to import our footage for editing.The original footage viewed on the computer runs fine, but once imported into Premier Pro there are green and black flashes that apear over the video. They apear to be random not apearing at the same place on the video and sometimes not at all. We have carried out the same procedure on our laptop, same footage from the same camera and it works without a hitch. Could it be a problem with our main computers graphics card and Premier Pro.

Our camera is a Sony a7 iii and our computer is a Dell Inspiron 7700 AIO with an Intel Iris GPU.

Any help would be greatly appreciated.
