Shrinking X265 [VERIFIED]

For 1080p video, an RF of 22–24 is generally recommended.

Avoid "UltraFast" or "VeryFast" presets if you want a small file. Use "Slow" or "Slower." It will take much longer to finish, but the encoder will find more redundancies in the video frames, resulting in a significantly smaller footprint for the same quality level. 4. Optimize the Audio Track

While x265 delivers half the file size of the older x264 (H.264) codec at identical quality, source files are often encoded with overly generous bitrates. Shrinking these files allows you to: shrinking x265

Depending on your technical comfort level, use these industry-standard tools:

High Efficiency Video Coding (HEVC), commonly known as x265, is already an incredibly efficient codec. However, when dealing with massive 4K Blu-ray rips or high-bitrate encodes, you can still shrink these files by 30% to 50% further by optimizing your encoding workflow. Why Shrink x265 Further? For 1080p video, an RF of 22–24 is generally recommended

Because x265 is already incredibly efficient, further shrinking an x265 file means you are —essentially decompressing the file and re-encoding it at a lower bitrate. This process always results in some generation loss, but the goal is to make that loss imperceptible to the human eye while significantly dropping the file size.

This controls how much effort the CPU puts into compression. However, when dealing with massive 4K Blu-ray rips

To be fair, aggressive x265 encoding has legitimate uses:
