Adolfo I need a couple of clarifications on what you said.
1-The main advantage is that you can then modify the content by just calling it from within FCP. You also save yourself quite a lot of space, since Quicktime movies with tranparency can be (not always, the animation codec is a subject in itself) very big.
What do you mean by this?
2-You need to make sure that Motion is to transparent background. One important tip, though. If when you import the clip, type and graphics look jagged, then FCP did a wrong interpretion of the Alpha type. Go to Modify > Alpha type and set it to “black”, to begin.
Where do I modify, in FCP or Motion?
3-Hoe do I begin with Transparant backbround in Motion, before I begin building my Project?
Thank you in advance for your reply to me Post,
Sebastian
