Accuracy is one of the most important factors to consider when selecting an AI video generator. You want to pick a program that has strong prompt adherence, meaning it is able to do what you ask it to do in your prompt. Writing a good prompt is essential to this process, but the model should be capable of handling nearly any request.
AI video generators are prone to errors known as hallucinations, especially when it comes to following the laws of physics. For example, a great AI video generator isn’t going to have a person floating through solid objects or have objects appear from out of nowhere (unless instructed to do so). While every AI program messes up sometimes, a capable generator won’t regularly produce these kinds of errors.
Because hallucinations are unavoidable with AI, the ability to edit your content is also important. More creative AI platforms are introducing tools to edit your output, which is great as it gives you more hands-on controls to perfect AI outputs. If many clarifying prompts are required or if you’re not able to edit your content, those are signs you may want to switch to another program.
Creativity is also important. Creative AI tools are often used for brainstorming, exploration and planning. The best AI video models can bring a wide variety of artistic ideas to life and build off your reference images.
Response speed is another factor. Generating AI videos is a complex task, so most models are able to create them between 2 and 5 minutes. Models that take longer to generate videos may be annoying to use, but if they result in better videos, the trade-off may be worthwhile. On the flip side, a model that produces good results quickly is noteworthy, too.
You’re also going to want to read the fine print, meaning a company’s privacy and usage policies. There are a lot of concerns about how AI models are created and whether copyright-protected content was used. Creators, celebrities and public figures have loudly voiced concerns over the ability of AI video generators to make content that’s too indecipherable from reality. This is especially worrisome as we’ve seen how companies’ guardrails against creating illegal and abusive content aren’t perfect. You ought to understand how the AI company is using your data, moderates content and what ownership or rights you retain over the videos — these vary by service.
