I have a client who has a video -- .mp4, 640 x 360 -- that they need cropped to 640 x 200 to use as a web banner.
I've compressed videos before from ProRes and converted to finish in H.264 before with the letterbox cropped off, so I know how to do this, but I've never encountered a situation where I have to convert and .mp4 to a cropped .mp4.
How do I do this while maintaining as much of the original quality as possible?
Also, no they don't have larger files. I've already asked.
