It's not necessary, but there should be. At least you can make a three-dimensional sign or text or something. Add gorgeous effects to your movie. Commonly used are: 3DS MAX, MAYA, etc.
2. Subtitle software
It is also necessary. But some non-editing software has some simple subtitle functions embedded in it, which is enough for general production. However, to be an excellent producer, you must know more professional software. For example: LiveType, EasyType, PowerTitle and so on. Domestic non-editing software has supporting subtitle system software, which is very suitable for domestic demand. But they all have limitations, that is, they can only cooperate with their own non-editing, and their versatility is poor. Photoshop, after effects and other software can also do subtitles, but the efficiency is low and the effect is good.
3. Code conversion software
Usually, the video files output by non-editing software are relatively large and easy to edit, but not easy to spread. Therefore, it is necessary to re-encode the finished film in order to slim down the file and make it easy to spread and burn. The most commonly used software is Canopus Pro encoder, which has good quality and high speed. But not all video formats are taken for granted. So we should collect more transcoding software. Convenient for daily work. It is best to make any format interchangeable. To achieve this goal, my experience requires at least three transcoding software. And we must be familiar with the use of various codes and the quality of coding.
It is necessary to master these softwares, and at the same time, you need to have corresponding professional knowledge of film and television, otherwise you can only be a good operator.
