you are working with (e.g., 1080p or 4K)
Encoding an 8-bit source to 10-bit H.265 can actually while improving quality. The 10-bit pipeline reduces the prevalence of contouring and banding artifacts (common in gradients like blue skies) that the 8-bit encoder struggles with. Consequently, the 10-bit encoder can use a slightly higher CRF value (which results in a smaller file) to achieve the same or better visual quality than an 8-bit encode. This makes 10-bit x265 an excellent choice for archiving, especially as modern hardware, even in many smartphones and set-top boxes, supports 10-bit HEVC playback.
Choose Same as source and select Peak Framerate . This maintains the original motion fluidly without generating unnecessary frames.
x265 has two secret weapons for shrinking: shrinking x265
: The most user-friendly option. Simply select the "H.265 (x265)" video codec under the Video tab.
If you prefer using the command line, FFmpeg allows you to pass advanced parameters directly to the underlying libx265 library. Here is an optimized command line for shrinking an existing video:
CRF ranges from 0 to 51. Lower numbers mean higher quality and larger files. you are working with (e
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?
The following comprehensive guide breaks down the core concepts, recommended settings, and step-by-step methods to successfully shrink x265 video files without destroying visual quality. The Mechanics of HEVC/x265 Compression

Here is how to approach "shrinking" your media using x265:
When shrinking files, avoid setting a specific "bitrate." Instead, use Constant Rate Factor (CRF) CRF 20–22 : High quality, good for movies you love. CRF 24–26 This makes 10-bit x265 an excellent choice for
