[AutoCrop=1] Auto crop black bars: true [0:214:0:214]
Are detected black bars have true values? 214px from the top and from the bottom of the frame.
If it true then it looks like double-cropping. SVP crop once and some application crop again. Maybe it is custom user settings of ffdShow crop option. See ffdShow properties.
I checked ffdShow and the crop option is turned off, so it shouldn't interfere with the SVP crop. Not sure how I can check the crop true value tho.
