A question for you all...
I have this trailer which has a bad aspect ratio. Basically, it's a 16:9 video, but it's been encoded to 4:3 w/ black borders.
I tried setting display width/height in mkvmerge GUI, but the video player still show the badly encoded 4:3 aspect ratio.

So, I was wondering, short of re-encoding the whole clip, how to fix this? Is it possible?

EDIT:
Gotten the width/height option in mkvmerge to work somewhat.
It now uses the correct aspect ratio, but the black bars are still there, which means the video is basically just stretched.
There must be a way to get rid of those!

mkvmerge has a cropping function as well.

Can't seem to get it to work. I don't know if I did it wrong or if ffdshow ignores the cropping parameters.
I added --cropping 1:0,45,0,45 I believe to copy 45 pixels off the top and bottom.
