To record a course intro video using Tella, start by opening the application and selecting the 'Record' option. You can choose to record your screen, yourself, or both. If you're recording yourself, ensure you're in a well-lit area and your camera is stable. If you're recording your screen, make sure all the necessary tabs or documents are open and ready. Once you're set, click the 'Start Recording' button and begin your introduction.

After recording, the next step is to edit your video. Tella provides a variety of editing tools that allow you to trim your video, add text, insert images, and more. You can also add transitions between different sections of your video to make it more engaging. Take your time to review and edit your video until you're satisfied with the final product.

Finally, once you're happy with your edited video, it's time to share it. Tella allows you to export your video in various formats suitable for different platforms. You can also share your video directly from Tella to platforms like YouTube, Vimeo, or your own website. Remember to check the video's privacy settings before sharing to ensure it's accessible to your intended audience.
