Hello, first apologize for my English, I am using the google translator.
Second, thanks for your comment. These are my first steps in stop motion and everything is new to me. When you say, framerate, you mean the number of photos taken? Or rather, the video program settings?
And a question I have is better 15 or 25 frames?
A greeting and thanks!

Framerate is how many frames are in one second.  A higher framerate makes the images change faster.
Any framerate above 10 fps (frames per second) is good.  15 fps is a good framerate that many of us use.
Keep is mind that when you change the framerate, you have to take more or less pictures for the same movement.  For example; if you go from 12 fps to 15 fps, you would change from 4 frames (at 12) to 6 frames (at 15) for a fast movement.

Don't use Google Trasnslator, isn't that good.  A billingual dictionary works much better.  Some dictionaries have verb tense guides, those help.  (My main language is English, I learn Spanish as a second language at school.)
