I just notices that, when cropping videos, the resulting movie cropping doesn't match exactly what I was seeing in the preview video (both in the small and int the enlarged detached one). There are always (except where the source video didn't need cropping ...) 1 or 2 pixels wide black borders remaining.
This is especially visible with some TV movies where the first line sometimes begins in the middle of the screen, and this half line remains in the output video, although I thought when setting the crop that the whole line will have been cropped.
I think that it is important to ensure that the preview very very matches exactly the output video, because (1) it seems that black borders, even if they are tiny, can improve more or less significantly the final file size and (2) because of the time needed for encoding a video, I prefer avoid having to work by tries and errors for getting exactly what I want.
Using automatic cropping helps a little, but I usually prefer to adjust manually, because of the often not perfect limit between picture and black border in many videos. Also, some TV videos have permanent logos embedded, and if these logos are located in the black border, I always enjoys removing them that way.
Things are exactly the same in 2.0.0 final and 2.0.1 beta.
