This is just a sample video. If you like what I'm doing, please let me know and I'll complete the whole video and send it here. If you want I can add subtitles, transitions and much more. I can add music in the intro. I'll highlight the things that you're explaining so the viewer can understand the concepts clearly. I'll remove parts of the audio and video that are unnecessary. If you want me to change the intro then let me know. Hope you like it.
