Warn people about FFMPEg anti aliasing.

[ilia3101]

@masc4ii I've seen a few cases of people ruining their footage using the FFMPeg antialiasing, maybe we need some kind of warning dialog? I appreciate the warning icons, but people still make the mistake!

It could pop up either of these two points:

• After selecting the option
• When beginning export, allowing the user to cancel and change the settings, or continue with warning

I don't mind how, whatever is easier to implement I guess. No hurry. Just wanted to open an issue to not forget so we don't forget.
