My HD video looks great when viewed as the download from my SD card.  When I open it in Movie Maker the quality is instantly downgraded.  Everything is pixilated and grainy.  Tried working with it anyway and then saved as 1080 and did a second one saved for computer.  Neither looks good because the initial transfer of the video into the program looked like ****.  I need to upload this file to YouTube for a work publication so it has to look crystal clear like the original.
