To record an engineering video using Tella, first, you need to open the application and select the 'Record' option. This will allow you to capture your screen, your voice, and your face if you choose to. You can then start your engineering tutorial, explaining the concepts while demonstrating them on your screen. Make sure to speak clearly and at a moderate pace for better understanding.

Once you have finished recording, you can proceed to the 'Edit' stage. Tella provides a variety of editing tools that you can use to enhance your video. You can trim unnecessary parts, add text or graphics, and adjust the audio levels. You can also add transitions between different sections of your video to make it more engaging. This step allows you to refine your video and ensure that it effectively communicates the engineering concepts you are teaching.

Finally, after you are satisfied with your edited video, you can share it. Tella allows you to export your video in various formats and share it on different platforms. You can upload it on educational platforms, social media, or send it directly to your students or colleagues. By sharing your video, you can reach a wider audience and contribute to the learning of engineering concepts.
