Don't autocrop video when having different dimensions of videos Lets say I want to have an video with 1000x1000px dimensions.

My source video is FullHD (1920x1080) and if I paste it into my Video Editing Screen it gets automatically cropped to fit the desired dimensions.




What I basically want is to have the video at its max height cropped down but therefore only displaying the 1000x1000 square from the original video, like so:



How would I do this?
First set your render settings Resolution to X:1000 px and Y:1000 px. In Video Sequence Editor right click on the name of the video that you are editing with the ending .001 (or similar). Open the options window with N and select Crop option and crop away the top, bottom, left and right to get the size that you need. To constantly see what you are doing the option at the bottom Use Backdrop is also good to be turned on.
