I have done several video tutorials: equipment: computer, video recording equipment (DV or video camera), Mike software: screen recording software, video editing software, image editing software, material (text, image, sound, video, etc ...) Talent: I have professional knowledge in this field, and of course I can invite professionals to cooperate with you. Have a good understanding of various video and audio files. The above is basic. A good video course requires producers to have good quality and excellent professional knowledge (I am also working hard). I hope you can succeed and good luck.
