what's the current BEST ai video generator for long form videos that work on scripts?

Say I wanted to make a video about how life was in the 80s, and I have a script for it, are there any real good video generators that take the script and generate a somewhat decent video (5min or longer) or has that not happened yet?

For long-form script-to-video, tools like InVideo AI, HeyGen, and Runway Gen-3/Pika (for custom AI scenes) are leading right now. InVideo handles automated script-to-faceless video with stock/AI footage, while pairing custom prompts with ElevenLabs audio gives the highest quality 5+ min result.

for a five-minute script, no single generator is consistently best from start to finish. I’d use a script-to-video tool for the general scene layout, then generate the more important scenes separately and edit them in manually. The main limitation with longer videos is keeping the style consistent throughout

The best results with less work is seedance. However tools like higgsfield have an interface for adjusting shot and camera settings. However for something to be coherent it's you to prepare the story, know what the prompts expect and output, then understand story telling. Wide shots for this, close up for the other. The mastery on when and how specific thing happens and prompt separates you from a block buster. Seedance 2.x would be around $0.7 per second for all bells and whistles.
