Track Motion 3D Source Alpha Not Working?

I might be doing something wrong. When I place a picture or video on a separate track and use track motion 3D source Alpha the picture or photo does not rotate when playing back.

I set my cursor to the beginning of the picture put in a keyframe. Go to end of picture, rotate the picture the way I want, I can see the picture moving the way I want it in my preview window. I then go to playback and the picture does not move. I even tried to render it out and the picture does not rotate.

If I use source alpha on track motion and move the picture it works.

Win 10 just did a upgrade last night to my computer.

Vegas Pro 17 Ver 353

i7 4770k no OC AMD R9 380 4g latest AMD drivers, 16gb ram, C drive Samsung SSD 840EVO, Drive I render to Samsung SSD 850, Storage drive 1 tb 7200rpm. Win 10 64bit OS.

I have manged to rotate my picture 90*. I can view that in my preview window. It is when I rotate 360* that the preview will not show. I just did the 90* rotate and will be happy with that.

When trying to motion track, you don't use 3d source alpha to rotate it. Instead, go into the motion tracking properties and set the motion tracking type to either shape and location or to perspective mode, try them all and see which works best for your purposes. It will do all the rotating for you, then you can go back and fine tune it from there. Also, set your tracking resolution down to 1 frame.
