Hello,
I want to know about this topic. I read many books,publication. I want to stand in this field. My topic is Promo animation. Content creation has seen dramatic growth over the past few years, and rightfully so. But one of the challenges is updating all of your old content. Whether you’re a trainer updating compliance content, a salesperson revisiting old presentations, or a marketer restructuring your branding; updating content is a challenge!  Video content however, poses an even bigger challenge. If you use live-action video, you simply can’t re-shoot scenes or update critical parts of your message without taking into account a large number of factors. Is this right information? I didn't get the right solution.
please help.

Any help will be appreciated.
Thank you.
