I tried to update this to the latest packages, but needed more work then I have time for. Was getting this error in it's current state:
[h265ize]: math.eval is not a function. Details can be found below in debug mode.
h265ize is a fire and forget weapon. A nodejs utility utilizing ffmpeg to encode large quantities of videos with the hevc codec. For more information visit ayrton.sparling.us.
If you have any questions or h265ize isn't working for you, feel free to open an issue.
h265ize will support AV1 once encoder support becomes stable & plex supports decoding it.
- Works on Windows, OSX, and Linux
- Batch file processing (can process a whole folder)
- Automatically detects video files (only processes video files found within a folder)
- Detects all audio tracks
- Preserves audio codecs
- Preserves audio track titles
- Detects and preserves all subtitles
- Detects audio language, if audio language is not your native language and native language subtitles are provided, makes those subtitles default
- Automatically upconvert vobsub/dvdsubs to srt subtitles on mkv files
- Detects bit depth and uses appropriate encoder profile (10-bit is common in high quality anime, supports 8-bit, 10-bit, 12-bit)
- Verbose and preview mode
- File overwrite detection (doesn't accidentally write over a file that already exists, other than in preview mode)
- Detects if file is already encoded in x265 and skips it
- Ability to make encoding previews
- Take screenshots of a finished encode
- Faulty encoding detection based on before and after video durations
- Maintains file structure in output folder (So in theory you could just take your 3tb movie folder and throw it into the script and the output folder should look that same but with x265 videos)
- mkvtoolnix - Used for upconverting subs in MKVs.
- vobsub2srt - Used for upconverting subs.

| Preset | Description |
|---|---|
| anime-high | A very good preset for all types of anime. Produces very good quality for a very small size. |
| anime-medium | Same as anime-high but uses debanding to produce better color gradients. |
| testing-ssim | x265's native preset just in SSIM mode. |

The stats file is located at the current working directory under the name h265ize.csv. This must be enabled using the --stats flag. The file is composed of several lines. Each line is in the format
[Finish Encoding Date],[File Path],[Original Size],[Encoded size],[Compression Precent],[Encoding Duration]
For example:
08/13 02:46:03 PM, videos/[deanzel] Noir - 08 [BD 1080p Hi10p Dual Audio FLAC][a436a4e8].mkv, 1964MB, 504MB, 25.66%, 2:51:16
To create 10 or 12bit encodes, simply pass the --bitdepth 10 or --bitdepth 12 parameters. Make sure you have the correct libraries or ffmpeg static build.
