And hello again, hope you aren't tired of these yet. I tend to do a lot of exporting, since it's necessary to see the videos on a certain device and the video title always being "Untitled" gets tiresome fast.
How about using the filename as the default produced video name, like this?
Would also help not overwrite some important videos by accident (since most would have different titles). Seems like a very simple thing to implement, hence the suggestion.
