I appeal to the authors of Videohive and in general to specialists who create video presentations in the program After Effects.
I have the finished text and the presentation in Powerpoint in Russian. This text will be used, the style of the presentation design and some other elements: the style of headings and texts, icons, pictures, the general style of the background - all this can be changed at your discretion, and something you can take. Based on the design style of this presentation, you need to create a new unique (well, perhaps with the use of your templates).
Who will respond, discuss further details and throw off the presentation and all that is needed.
