Changing Project Settings - Odd Behavior
I don't even know how to describe this well enough to search on it. I have a project with media at 1080i. I wanted to edit with my project settings much lower to match my intended destination, but when I put clips to the time line, they were zoomed in and it was only afterwards I discovered how to force them to fill the frame correctly. But I digress. My problem is best described with the attached images.
The first image shows what my timeline looks with project settings matching those of the media. https://drive.google.com/file/d/0B4aixMPlL0JvVXZGODdoS2FvdWc/view?usp=sharing
The second image shows what happens to my time line when I change the project settings to 640x360. https://drive.google.com/file/d/0B4aixMPlL0JvVHJTYzRkWVNIcnc/view?usp=sharing
As you can see (hopefully), some clips expand and overwrite clips that come after them, as indicated by the black cross lines. The image and audio in those black cross lines is null. That is, those areas are background when played and void of audio.
Obviously, I'm doing something totally newbish, but is there a way to convert the project properly without going back and re-cutting my project?
