Assign frame as thumbnail for mp4 file


New member
Is it possible to assign a thumbnail from a frame, or graphic file, when saving a mp4 file? Such that the selected frame appears when the file is viewed in most file manager programs? How would I do that?

All my searches for "thumbnail" refer to the thumbnail bar in the edit view.

The only time I've seen such an option is in the file viewer itself.

Don't remember which one but one had an option to not display a "black screen" frame.

For anyone interested, here is my workaround. After saving my edited video file, I reload it in VR and save the frame I want to use for the video thumbnail, as a PNG file.

Then I open Tagscan (which I traditionally use to edit audio file metadata), and drag the video into the Tagscan window. Selecting the video file in Tagscan, I then add a "cover" photo selecting the PNG frame capture. Then "Save".

Refreshing the File Explorer view, then displays the frame capture as the video file's thumbnail, instead of a seemingly random thumbnail.
