Which prospect is better, post-film synthesis or film and television special effects?

Nowadays, we are rich in material things, so we can't live without entertainment. The film and television industry must be developing upward, with obvious input and output, short cycle and quick results. The film and television industry needs funds, and the start-up capital of good works will not be too low, but there are also deep water areas and risks. A good work may not have a good market, but it may take time, such as a journey to the west.
