I had an inconsistent experience

It works like a charm at making a time lapse of photos. My problem is that when I first tried this in October, I was able to select photos from iPhoto easily from Zeitraffer, but now in December I can’t and had to export photos from iPhoto first before I could browse for them in Zeitraffer. I don’t know why the difference. Also in October, when I wanted to change the aspect ratio, I thought the right side of the video was cropped, but now in December it is cropped justified on both right and left sides, but I needed and anticipated it to be cropped on the right side. Please add some instructions and options involving iPhoto and cropping my time lapse video. Thanks.
