Whats the BEST free Ai video creation software to create nice xmas shorts?

You have been on the forum for over a decade, nearly two,
so you've probably been doing IM for twenty years.

Google AI VIDEO GENERATORS and find something that
works for you.

The "video" that you are referencing was probably created
with an editor, which some people are using their phones
to make that type of thing.

I do not have the patience or inclination to do work on my
phone, I do my work on a desktop computer and sometimes
on my laptop when I am lounging around.

Besides using an online video platform where I can upload
a script, I also use a video camera and editing software.

If I could figure out how to make videos, so can any other
adult, or even a child could do it. No offense, just facts.

I suggest that you take some time to read a book or watch
a YouTube about making videos.

Then find a platform that offers video clips, images, graphics
or whatever you plan to use, learn to produce videos and
get busy doing it, or else hire someone to make the videos
for you if you are not able or don't want to be bothered.

This whole video thing may seem overwhelming but it is not
rocket science, this likely concludes my contribution to this
topic and I wish you all the best with your project.
