For users who prefer the speed and flexibility of the command line, FFmpeg can achieve identical or superior results. Open your terminal or command prompt and use the following optimized command template:
If you want to shrink x265 to absurdly small sizes, you must .
using the High-Efficiency Video Coding (HEVC) standard, typically via the open-source x265 library . This codec is designed to provide roughly double the compression
Open HandBrake and drag-and-drop your x265 video file into the main window.
Elena watched Interstellar again. "Looks good," she said, reaching for popcorn. shrinking x265
This is the most crucial setting. For x265, a value between 22 and 28 provides an excellent balance of size and quality. Lower number (e.g., 20): Higher quality, larger file. Higher number (e.g., 28): Smaller file, lower quality.
The Ultimate Guide to Shrinking x265 Video Files: Maximize Compression Without Losing Quality
His first pass was cowardly. He set the Constant Rate Factor (CRF) to 18—near-transparent quality. The resulting file: 22 GB. A victory, but not a shrinker's victory. Elena was happy. Leo was disgusted.
Offer options ranging from ultrafast to veryslow . The slow preset is often preferred for "shrinking" as it maximizes compression efficiency. For users who prefer the speed and flexibility

With these details, I can provide custom command lines and optimal advanced flag tweaks tailored to your exact library. Share public link
In the tab, ensure the Format is set to MP4 or MKV (MKV is preferred for subtitles and multiple audio tracks). Step 2: Dimensions Tab (Optional Downscaling)
Black bars at the top and bottom (or sides) of a video force the encoder to waste precious data rendering a static black screen. Use the "Crop" feature to remove these black bars so the encoder only focuses on the actual image. Hardware vs. Software Encoding This codec is designed to provide roughly double
"Shrinking" also applies to the output file size.
-c:a aac -b:a 192k : Compresses the audio to a lightweight, highly compatible stereo track. Advanced Tuning Parameters
Every +6 increase in CRF roughly halves the bitrate (and size), though it also decreases quality.
