Hi,

This is Donald. I shot some videos with a DSLR at 1920x 1080 50i (PAL mode) with a hand-held camera stabilizer. I copied orginal video clips which are in MOV mode to my desktop. I then use Windows media player to play a video and the image is is hypnotically smooth, and overall quality is incredible. However, I imported the video clips to Window movie maker and then save it either with the option"For Highest Definition Display" or "Window 8 (1080P)", the output videos became a lit bit Shaky and it is obvious to see. It's not for a particular out video, actually all output video have such issues.

For your info, I am runing Windows 7 ultimate and Windows movie maker 2012(the latest one for windows 7). My desktop computer is purchased three years ago running i3 processor and graphic card which is fully capable of playing Full HD videos.  

What I have tried to troubleshooting:

1. Follow the link beloe to check Codecs and update video driver, and doesn't help

Movie Maker video quality is significantly less than the HD original clips.

2. Convert orginal MOV files to other format such as AVI or MP4 with mainstream format converters, found that the output videos quality is similarly downgraded.

3. Repeat above steps on another latest computer hardware, and problem persists.

Below is an example of my original video clip info for your reference, and hope you can solve the issue. Thanks!!
