When choosing to save video in MKV format, it means you are saving a file with a large file size. MKV videos, especially HD MKV files, usually occupy a lot of your storage space. And you'll want to resize the MKV files for smaller size by re-encoding, lowering video resolution, frame rate and bit rate, and cropping. To achieve that, you need a powerful MKV resizer or cropper. iOrgSoft Video Converter (Video Converter for Mac) will be the one you want.
This program allows you to do video conversion among almost all video formats, which means, you can convert MKV to a format that is in smaller size, like FLV. Of course, if you don't want to re-encoding, you can just lower the video resolution, frame rate, bit rate, and choose MKV as the output format for a smaller size. Additionally, you can crop MKV files for saving space as well as removing black bars, or you can trim MKV file to get rid of the unwanted part to reduce its size.
