The first time I animated my storyboard, I used Adobe Flash to execute and exported it into mp4. However, even though I separated the 11 scenes into separate Flash files, problems still occurred and it could not be exported.
I’ve wasted quite a lot of time animating the scenes in Flash before problems began to rise. But after a few attempts, I’ve decided to solve this problem completely by switching to After Effects instead.
This made things much easier for me in terms of exporting the video. Although it may be slightly more troublesome in terms of animation (I have to separate the visuals into individual layers in order to animate them), it was not as lag as Flash and it was generally easier to use.
