Composer : How to handle transparent image backgrounds and master animation workflows in Composer?

Hi everyone,

I recently started using Composer, and since I'm still getting used to it, I could use some advice.

I understand the core concepts and features through tutorials and documentation, but I want to use Composer's animation features to visualize a service manual/documentation.

 

I have two main questions:

 

1) How can I make imported images have a transparent background? 
  - I understand this might require specific requirements, formats, or handling alpha channels. 
  - Could someone guide me on the exact method or best practices for handling image transparency in Composer?

 

 

 

2) Which workflow is more commonly used in Composer: Views on the timeline or direct timeline editing?
  -  As I understand it, there are two main approaches:
  - I've noticed that animation work in Composer involves quite a lot of manual effort and takes up a significant amount of time.

  • a: Creating each section as a "View" and placing them sequentially on the animation timeline.
  • b: Building the scenario directly in Animation mode without pre-made "Views

   - Since I'm not very familiar with video editor-style workflows yet, does anyone have tips, insights, or best practices to make this easier? 
    - Which method is more efficient in actual workflow/practice?

  

 

Thanks in advance for your help!
