It's got potential, and an obvious learning curve, but falls a bit short when it's time to output your video, without encoding settings to match the level of professionalism found in the editor. It might work if you could at least export your work to an AVI file using a lossless codec, then encode it elsewhere, but AVI export isn't available. And you definitely need a manual &/or Help file.
You can install the app wherever you like by clicking the custom button on the initial dialog, but just running the installer, rather than as Admin., you can't select something protected like the Program Files folder. Otherwise it installs to Users\ [UserName]\ AppData\ Local\ Turbo Play\, with an explanation that it needs write permissions for frequent updates. That user folder also gets a copy of the installer/uninstaller, while folders are added to Users\ [UserName]\ AppData\ Roaming & Documents. I recorded ~22k new registry entries in my Win11 VM, as the installation causes a re-write of the component hive. That said, the app itself does not have much of an impact on the registry beyond associating several file types with the app.
