I'm trying to scale a clip's width by a lot, intentionally stretching it in the process. However, whenever I try this, it either scales the height of the clip along with it, or it crops out parts of the clip. I need a way to lock the height in place while scaling the width to a custom amount.

For example, if the dimensions of a video clip are 1920x1080, I would want to change the 1920 dimension to 3000 so that the final clip is 3000x1080. According to another thread, I can't do this by setting a custom aspect ratio because custom aspect ratios are "impossible to implement". I need a way to do this without spending a buttload of money per month on Adobe Premier or having to deal with the constant crashing and ridiculous price of Sony Vegas.

I find it incredibly hard to believe that something like this is impossible.


Edit: I found a way to do it. For anyone else wanting to do this, there's little blue tabs on the corners of your clips when selected. Drag those around.
