Having updated to Win 10, Vegas Pro 12 appeared to be working very well. Better than with Win 7. then I had to rotate a not very vertical clip, and although it rotates, I could not get rid of the wedges of black all round.
After a bit of head scratching, I tried right click clip/ switches/ uncheck maintain aspect ratio. I can now expand the clip, and hide the black wedges.
Anyone else had this problem, and did you find a cure?
I also have Vegas Studio 10 HD and the crop tool works perfectly in that.
Donj't use Vegas but could you just increase the scale of the clip?
Un-checking “maintain aspect ratio” does just that. I can then expand the clip using the crop tool. I havn`t looked to see if it can be done with anything else.
