Welcome to the forum.
If you have any questions try doing a search first by clicking the magnifying glass top right. You might find your question has already been asked and it will save you a lot of time. If you can’t find an answer, then just post the question. In your case, just type 'jerky video'. There is plenty on that subject.
Maybe if you put a vid on here we could help you more if you cant find an answer to your problem.
If you want to check your spelling, put your cursor over the word with a red line under it, click once right and choose the correct spelling.
Enjoy
