I am doing a tutorial that shows animation of a text. Some composition are with a solid layer and on it, some are not. And I found soil layers are useless in this context. Is there any criteria to decide when you need solid layer?

Correct answer Rick Gerard

With almost all delivery codecs, transparency renders as black in the format you would use to share a video. Changing the Composition Background color is only really useful if you need to render an RGBA file, a file with transparency, and you need to Premultiply the anti-aliased edges of the footage with a specific color. That is a very rare workflow only used when you are assembling a composite that also needs further work. All editing and compositing apps default to straight alpha, and that produces the most acceptable results almost all of the time.
