• both iterlaced and "normal" (progressive) videos are generated, container is mkv since it supports everything without adding too much of its own logic.
• send frame means preserving the frame rate by extracting one of the two (or more) frames (making the picture half, or more of size), then returning only one frame.
• send field adds a frame, for each encoded frame ("field") in the current frame, as the amount of frames doubles (or more) so does the frame rate. this is the better option.
