If you are worried about malware or legality, you can achieve the same "low data usage" goals through legitimate services.

| Scene Type | 500MB H.264 (YIFY-style) | 500MB H.265 (PSA-style) | | :--- | :--- | :--- | | Static dialogue | Acceptable, slight softness | Good, minor detail loss | | Night sky / space | (visible gradients) | Minor banding, dithering helps | | Fast action (car chase) | Blocky artifacts, smearing | Manageable, but blurry | | Textured surfaces (brick, sand) | Washed out, looks like clay | Some texture retained | | End credits | Legible but pixelated | Legible |

Not every movie compresses well. If you want to watch a 500MB rip, choose your films wisely.
