| Preset | Description |
|:---:|:---|
| basic | Overall good preset, will always create high quality videos but may produce large files. |
| anime | A very good preset for all types of anime. Produces very good quality for a very small size. Warning: this preset creates a nonconformant, high latency encode. |
| testing-ssim | x265's native preset just in SSIM mode. |
#### Examples
*
./h265izer -v big_buck_bunny_1080p_h264.mov
* Stats file
The stats file is located at the current working directory under the name . This must be enabled using the --stats flag. The file is composed of several lines. Each line is in the format[Finish Encoding Date],[Filename],[Original Size],[Encoded size],[Compression Precent],[Encoding Duration]For exmaple:
Creating 10bit encodes
To create 10bit or 12bit encodes, simply pass the or --12bit parameters respecively. You may need to install x265_main10 and x265_main12` (x265 main10 and main12 libraries) in order to encode in 10/12 bit.
