FSTHUMB File - How to Convert FSTHUMB to MP4 Video?

The FSTHUMB file type may seem strange to most people, not only is it unpopular, but also it cannot be opened, edited or uploaded with any program. People probably wonder whether it's possible to convert FSTHUMB file to the universal MP4 format. Absolutely not! Here is the reason.

FSTHUMB file is actually a Thumbnail Cache file generated by a terrific video editing program - Wondershare Filmora, alongside with a .wfp project file. It is produced to help fast load thumbnails and images when opening Filmora project file next time. You can even delete it, which makes no difference to your project but takes a little bit longer loading time. In short, since there is no video information in FSTHUMB file, it's impossible to convert FSTHUMB to MP4.

Don't be upset, however, converting FSTHUMB file to MP4 video actually means rendering WFP project file to MP4 format. I'll demonstrate the steps below.
