Tools used for this studio:
1. "4-Gradient effects"
This tool allow the text to change colour when the text moves around within the stage. This tool is interesting as i do not need to change the colour of the text manually instead, i can just apply this effect.
My updated e-learning:
I've used text and a .gif together to make a tiny video.
I know this effect as i've watched a video from Youtube explaining how to do certain effects like Mosaic, Text shine and the one mentioned above. They teach step by step and i think it is very useful for me as i just started using After Effects.
2. Toggle switches
I can add a few layers together by switching overlaying position of the images by switching on the toggle switches. By clicking on the toggle switches, we can see the edit drop down menu. Certain effects like "screen" can help me to make the background opacity lighter even without changing its opacity in the opacity panel.
p/s: my iron man's video is not that clear as i rendered it as a windows media video.
