I think the video is running a little bit fast after exporting.
Before the video, I tried to use iMotion to make animations at university. That software was quite easy to be used for me. However, as I use Windows at home, I needed to look for an animation software which is supported in Windows. Finally, I found Ulead GIF Animator that software is quite cheap and very user-friendly. After finish every clips of each food, I combined and exported them to avi format video with Adobe Premiere CS3.
