Is there a portable version of Wondershare Video Editor?
No, there is no portable version of Wondershare Video Editor. I have checked the official website and the only download points to the installer of the application.

Note: The new name of the software is Filmora Video Editor. Although it's released by the same company, they have changed the name of the application.
LOL, last time, I want to remove watermark. I used Joyoshare Media Cutter to crop the video size. And it provides 5 free times to use and I don't need any payment.
