I am afraid videos can't motivate them unless you have achievers relevant to their areas of struggle sharing their stories in it.
I have a lengthy solution to your brief question. Assuming that you have women employees at different levels and age groups in your firm, please sort them accordingly. No problem is similar. Every age group has its specific life cycle concerns.
Since you are designing a program, I request you to first group those challenges and then find specific speakers who have already faced, failed, and resolved them.
Videos are cost-effective; however, they don't do all the good as they are not interactive. Please invite speakers to your firm and let them speak directly to your employees. Unlike counseling sessions, these are a lot more open and live with almost everyone under one roof. Hence, time-saving and help in bonding far greater than private sessions.
If I may ask, which city are you in? I wish to nominate someone if I know a person aligned with the challenges your employees are facing.
Wishing you all the best for your initiative.
