Now computers are widely used in color scanning hand-drawn line drawing, so you may be talking about animation (middle cutting).
From what period in the last century, animation processing industry flourished in China. Many animation teachers in colleges and universities are from animation processing industry, but they gradually decline after the new century. But so far, there are still many specialized animation outsourcing companies. I heard that companies in Wuxi received many Japanese movies.
For a new career, draw a second original painting and draw a line between the two lines of the two paintings. You don't need to draw well, just hold the stroke line according to the regulations.
Charge per piece, about five to seven yuan per piece (never outsourced, I can't remember). Sitting at my desk every day, I work hard and paint carefully, just like a worker and other occupations. If you can't draw, you can't make a big production, and your salary can't go up.
For those who want to develop into the animation industry, outsourcing companies are just a dynamic investigation and can't learn anything.
For animation creators, cutting without painting is really cutting in the garbage. This process of animation determines the appearance of animation directly presented to the audience. If it is not good, it will be criticized by the audience. If it is not in time, who will deliver it to you?
