mysticeagle and markdc, thank you very much for your response.

Now, I am thinking to use editor program. As you suggest, I will render frames using poser, and add sound later.

It seems that Premiere is good one, although it is expensive. Probably, I should get it. I need a reliable program.

I don't have Mimic yet. But, I would like to get it in the future.
Is Mimic reliable, and good ?
