I Prompted ChatGPT: Can I do crf 22 or 21? Do you recommend it as an in-between option?

Response:

Yes, you can use CRF 21 or 22 as in-between options. The CRF scale is continuous, meaning you can choose any value between 0 (lossless) and 51 (worst quality). Using CRF 21 or 22 offers a slightly higher quality than CRF 23 with a moderate increase in file size, making them good choices if you're looking for a better balance between quality and compression.

Why choose CRF 21 or 22?

• CRF 21: Provides almost imperceptible quality loss with slightly larger file sizes than CRF 23. Ideal if you're concerned about maintaining higher quality in fast-motion content.
• CRF 22: Just a bit closer to CRF 23 but still leans toward better quality without a significant file size increase.
