But the supplied "MovieStar" capture/editing software's editing functions won't work and the program remains unstable. I keep getting errors like "Unable to build temporary movie for unknown reasons." Of course I read their FAQ and the manual (no section describing the problem.....no troubleshooting section). So far, I am unable to do anything with the clips but trim the ends to shorten them. To do this I have to "produce" a new clip for each editing function. I cannot combine clips by inserting transitions. And it still crashes the system....even with nothing else running. I suspect it is not compatible with my GeForce 256 video card. So I emailed their "support" address through their website [...] explaining the problem and got back a computerized response. Then I called their "support" number (long distance.....not an 800#) and was put on hold with the explanation that the California phone system was on the bugger implying that if I couldn't get hold of them it wasn't their fault. So, I left them a voice mail message with my office number. They called and left me a email where I was supposed to be able to get email support from them (anthonyp@dazzle.com) which was returned to sender.
We installed each video editor on a Windows 10 PC running on an Intel Core i5 processor and an Nvidia dedicated graphics card. We used each suite to edit the same two videos: a 4K NASA video from inside the International Space Station, and a 1080p game capture video from Overwatch. We tested most of the filters and transitions in each suite, and cut the same edited versions of each video in each program. We then exported the videos to various file formats and media, as well as web services, to test output quality and speed. Where software offered a notable special feature not supported in the other products, we tested it when our hardware and software setup allowed it.
With the popularity of video content today, you'd think Microsoft would make a simple video editing tool even more prolific and available than they even had with Windows Movie Maker. Many times small business and particularly individuals, don't have the funds available for the more involved editing programs, or the time to learn those with huge learning curves to create even the simplest results.

We combined a text opener with five clips linked by a cross-fade-type transition into a 2.5-minute video shot at 60 frames per second, and rendered the projects to the MPEG-4 format at 720p. We timed rendering at both 60 fps and 30 fps. We adjusted settings to take advantage of hardware acceleration for all tests whenever possible, setting them in either the preferences or the rendering controls for the best speeds. Apple’s iMovie, the lone Mac-only app, is not included in the timed comparisons.
