To record a customer success video using Tella, first, you need to open the application and select the 'Record' option. This will open up the recording interface. You can choose to record your screen, your webcam, or both. If you're recording a customer testimonial, you might want to use the webcam option. Make sure your camera and microphone are properly set up and working. Then, click the 'Start Recording' button and proceed with your video.

After recording, the next step is to edit your video. Tella provides a simple and intuitive editing interface. You can trim the start and end of your video, cut out any mistakes, add text or images, and even add transitions between different sections of your video. This allows you to create a professional-looking video without needing any advanced video editing skills.

Finally, once you're happy with your edited video, it's time to share it. Tella makes this easy by providing a 'Share' button right in the application. You can choose to share your video directly to various social media platforms, or you can download it to your device and share it manually. This makes it easy to get your customer success video in front of your audience.
