How much will it cost to make a feature film using Sora? 

Airhead by @shykids

While OpenAI has not given any indication on costs or pricing for its text-to-video model, it was fun diving into some projections based on current hardware assumptions. Factorial Funds recently released a blogpost diving into how the inference compute needed if Sora made say, 50% of Tiktok and Youtube videos released every day — and they landed on an estimate of a whopping 720,000 H100 Nvidia GPUs. For context, each H100 chip retails for $40,000 today. 

I was curious to put it into context of a feature film. Assuming a shooting ratio of 100:1 minutes, a H100 chip running continuously for 24 hours would produce 120 mins of “raw footage”. Following similar assumptions around fail rate and peak demand, we’d need 20 H100 chips running continuously for 20 days to create enough footage for a two hour film. 

And that’s just for inference compute. Throw in initial research and development costs, maintenance and troubleshooting, scaling, and Open AI’s pricing — and the costs start looking prohibitive to the indie creators and studios. 

This is where the game gets interesting. Will compute costs go down over time? Will free and open source alternatives to Sora —like Open-Sora, Mora, and Stable Video Diffusion — ever become comparable in quality?
