Hello! When looking for videos to download for reposting on YouTube Shorts, it's important to make sure you have the necessary rights to use and share the content. One option is to search for videos on platforms like Pixabay, Pexels, or Unsplash, which offer a wide range of free stock videos that you can use without worrying about copyright issues. Another option is to create your own videos using free video editing software like OpenShot or Shotcut, which allows you to combine different clips, add music, and create engaging content for your YouTube Shorts channel. Remember to always respect copyright laws and give credit to the original creators when necessary.
