What does it take to be a film commentator?

After watching the movie carefully, write a copy in your own words, record the finished copy with recording software, then edit it with post-editing software (Pr), and edit the movie fragments against the copy. After completion, add subtitles, add subtitles sentence by sentence, align with the recorded voice, and then render. Difficulty: Copywriting requires a certain level of writing (simply explaining the film clearly), and recording voice: fluent in Mandarin and clear articulation (with emotion, otherwise you will read the text). Post-software: This is not difficult. There are various editing software tutorials on Baidu. You need a little editing and directing ability to explain the film. For example, you can add humor elements! It's that simple.
