Of all the production stages, sound design took an unexpected amount of time. I spent almost a week resolving the film’s sound issues, including sound effects and AI dubbing.

Soundtracks

In the approximately 4 min 20 s video, I layered about 300 audio tracks, designing sounds for almost every element in the scene, including the two main characters, the aircraft, the laboratory, and the military base. Unfortunately, I have no idea how to design sound effects by my self, so I had to spend a lot of time searching for sound effect resources online, then selecting appropriate sound effects to place at the right time, and adjusting the relative volume between them to control a reasonable listening experience.

AI dubbing

Besides the sound effects, my video also had a few lines of dialogue, so I decided to use AI voice-over to read the narration I needed. After consulting with friends who specialize in sound design, I chose the MiniMax platform because its AI reading function has a good grasp of the characters’ emotions. After a period of modification and debugging, I achieved relatively satisfactory results and used it in the final video.
