Encode without resizing?

Is it possible to encode to f.example a 1280x720 profile without having badaboom resize the video to either aspect or full frame? I regularly archive 720p recordings from cable, but I crop away 4 pixels from the top and bottom, and 16pixels from the sides to remove black borders in the recording, resulting in a 1248x712 pixels framesize. I really don't wanna have it resized by Badaboom to 1262x720, just wanna archive in the original resolution/framesize.
