Hardware Issues

OpenShot Video Editor needs 4 GB of memory and a multi-core processor. In addition, it needs a 64-bit OS and an additional 10 GB of hard disk space.

These minimal requirements are doable, but if you want a smoother running system, it also suggests 16 GB of memory. It may lag if your system falls short of the specifications.

Large File Sizes

Both your computer and the software might be unable to handle a large file size. Even if your system satisfies the minimal requirements, the video files may still be too large.
