Automatize "save JPG without asking quality"

I have hundreds of jpg files which I need to change their size.

The action I run is:

Image size 50%
Save

Quite easy but I need to save the file without asking the quality because in that way I have to stay behind the computer clicking ACCEPT every time it saves one.

I tried overriding and not overriding but in both cases it asks for "quality".

Is there a way to do it?

Thanks in advance

The solution is a one click one: disable the menu icon in front of the "save as" step....

Thanks for the answer but I don't understand what you mean.

If you mean to uncheck the box with "Override action with 'Save As' commands" in the batch window, I already did that with no results.

Well, I solved the problem. The file must be "saved as" in a different folder than the original.

As for the meaning of my answer, sorry for the confusion, you need to uncheck the menu logo in the action itself, on the column on the left of the text "save as"
