Hi, you have a few options; it’s not such a problem these days.
We have built-in automatic generation for videos, galleries, and even for models and channels in Tubes Booster.

If you want a truly professional solution, Tube Sites Submitter handles this generation by reading the videos and using that information to create both the title and the long description for you.

I can set up any solution for you—just let me know.
