Filename for screencaps

[Reuental]

Greetings.

Is it possible, to set the screen cap function so, that it names the captured pictures after the source file?
Meaning, that instead of "vlcsnap-" I would get "filename-"?

When you go back and try to organize some old screencaps, it can be hard to remember what you were watching when you took the capture. Fortunately they did incorporate this several versions back; you can use $N for the filename.
