| Source Type | Original Size | Shrunk Size (High Quality) | Shrunk Size (Archival) | Notes | | :--- | :--- | :--- | :--- | :--- | | | 25-35 GB | 4-6 GB (CRF 20) | 2-3 GB (CRF 24) | Use 10-bit. Avoid cartoon animation (which can go smaller). | | 4K Blu-ray (HDR) | 50-90 GB | 12-18 GB (CRF 22) | 6-10 GB (CRF 24) | Must use 10-bit. Keep HDR metadata. | | Web-DL | 5-10 GB | 2-3 GB | 1-1.5 GB | Web streams are already compressed; shrinking further is risky. | | Anime (1080p) | 10 GB | 1-2 GB | 500 MB | Anime has flat colors; x265 excels here. | shrinking x265
