I am a Software Engineering student. I want to use Yolov8 to make a barbell move track tracker as my homework. Here are more details:

Input: The user can upload a video of using barbell to exercise at the frontend (A webpage).

Handle: Get the video, handled it by yolov8, and get a new video which draw the movement track of barbell with lines.

output: The user can get the new video at the webpage.

How to use yolov8 to handle it? Where can I find the model? If I need to train a model by myself, where to find the dataset?

Thanks for you guys' help. You are all gigachad.
