I'm conducting some research to help with a personal project. I am interested to know your personal preference when working with animation source files. If you don't directly work with them, feel free to answer for which method your colleague or studio uses.
This next part isn't necessary for my research but I would also be interested in a short explanation of why you do it the way you do it, whether it be personal preference, efficiency reasons, tool integration, you've been doing it that way since forever, etc. Maybe it'll spur some interesting conversation.
