Original GitHub issue: https://github.com/NickeManarin/ScreenToGif/issues/351

When specifying video output options and attempting to increase or decrease the filenumber, the code here will always affect the last number of a filename:

github.com/NickeManarin/ScreenToGif@1a4399a062/ScreenToGif/Windows/Editor.xaml.cs (L4726)

Meaning a filename with an extension specified that includes a number will increment / decrement the extension rather than the filename itself.

As an example, with a filename like filename25.mp3, incrementing five times would produce the following output:

• file25.mp4
• file25.mp5
• file25.mp6
• file25.mp7
• file25.mp8

The file extension is not supposed to be typed directly into the filename text box. There's a combo box (selector) to the right. :)

Btw, which version are you using? The latest version has a dropdown (with the file formats) very close to the text field where you type the filename.

I am not using any version of this, I'm just passing along information from the thread that it seems you have already discovered 😄

Figured someone should actually raise the issue on the repo when I saw there was no bug filed.

That user was using an old version of the app, in which the file format dropdown was not very close to the filename.
The current version of the app has a more easy to understand layout. So this is no longer a problem.
