One of the documentary makers asked him why he had a dedicated sound guy; the rest of the production was so stripped back, there was no lighting guy, why a sound guy? Edwards responded that, as long as you’ve got a good story that keeps them hooked, the audience will forgive bad visuals but they won’t forgive bad sound. It’s a sentiment that I believe was also echoed by Robert Rodriguez in his low budget filmmaking days. Good sound is essential to keeping people tuned in and immersed in your video. It’s why the number one thing recommended to any YouTuber starting out is “get a good microphone”.
The graphics are 80% of the way there now. Weather and character animation still needs work but the most bang for the buck might now have swung round to sound design.
