Risk: High

Starting a side hustle in AI Game Trailer and Marketing Video Generation can be risky for someone starting from scratch, especially if they can't afford to lose money. Beginners in this field could potentially lose money invested in software tools, time spent learning AI technology, energy in creating videos, and confidence if they don't see desired results. There have been cases where beginners spend money on expensive AI tools and training but fail to generate sufficient income. Startup costs for AI software and training can be high and may not pay off immediately, leading to initial losses. Online discussions mention instances of individuals failing to make a profit or losing money due to the competitive nature of the industry and the need for high-quality output. I'd rate the risk a 1 out of 3 because of the significant potential for financial losses, time investment, and challenges in achieving profitability.
