To further customize your split layers in After Effects, there are a few more tips to consider:
In addition to renaming and adjusting the duration of your split layers, you can also apply different effects to them. For example, you can use the “Color Correction” effect to change the color of a split layer, or the “Blur” effect to soften the edges of an image. To apply an effect, simply select the split layer, go to the “Effect” menu, and choose the effect you want to use.
