Hi there, I guess the best format for your software is to depict a realistic 3D smart watch featuring your actual software on the screen. Furthermore professional stock videos showing real people and custom graphic elements in animation to complete the communication process.
I'm able to design the explainer/commercial video providing a copywriting support either. My work will be also to provide you a shortlist of mother tongue voice talents to select from the proper candidate for the voice over. Music track and sound effects will complete the communication work.
If my idea appeals your tastes, please, take a look at my in-site portfolio or search for my channel: AI productions in the world's most famous website for videos.
(I can't post my link in the proposal for this website's Terms & Conditions).
And, please, feel free to contact me for further details and information.
Best regards.
A. I.
