Third-party aggregators like fal.ai display direct dollar costs per prompt generation instead of relying on credit systems.
Workflow outlined in the video
- Download the MiniMax H3 open weights from Hugging Face for free local generations up to 768p, or use fal.ai for cloud 2K renders.
- Prepare prompt reference assets, limiting image inputs to five or fewer to maintain the base $0.13 per second pricing rate.
- Configure video generation parameters on fal.ai or MiniMax, selecting 2K resolution, 24fps, and target aspect ratios (16:9, 21:9, or 9:16).
- Write multi-shot textual prompts with embedded timecodes to structure multi-angle character cuts and dialogue sequences in a single pass.
- Compare MiniMax H3's 2K outputs against Seedance 2.5 to determine whether higher resolution offsets physical movement trade-offs.
