Okay! So Aditi, first you have to learn how to make videos and know what's UGC. Try to search UGC creators on Instagram and see/learn how they are making videos. try to make it with products you already have at home and use and practice. Once you start making good enough videos, make 6-7 different type of UGC videos for your portfolio and then start reaching out to brands. this is a high level plan. If you want a detailed plan, I can write a blog about it so it will help others as well. also, please keep in mind that while making videos always research what brand stands for. What is there vibe, etc.
