# Video Encoding Samples
|
|
Video Encoding Samples (VES) is a project to determine the ideal (or even best) settings for any available encoder through comparison with [VMAF](https://github.com/Netflix/vmaf), SSIM and PSNR. It was previously used to generate the data shown on [the old website](https://ves.xaymar.com/1.0/) which will eventually be replaced by new, up to date information.
|
|
|
|
## Requirements
|
|
* A CPU with 4 Cores & 8 Threads, or 6 Cores & 6 Threads.
|
|
* Any of the compatible Operating Systems:
|
|
* Windows 10 64 bit
|
|
* Windows 7 64 bit
|
|
* [Node.JS v15.0 or newer](https://nodejs.org/en/download/current/)
|
|
* [FFmpeg](https://github.com/Xaymar/video-encoding-samples/releases/download/0.1.0/ffmpeg.7z)
|
|
* [VMAF Model "4K RB v0.6.2"](https://github.com/Netflix/vmaf/tree/master/model/vmaf_4k_rb_v0.6.2)
|
|
* Any number of input Videos
|
|
* A lot of time.
|
|
|
|
## Usage
|
|
The tool currently has no special parameters and reads its entire configuration from the `config.json` file, so you can invoke it by calling node.js with the script argument:
|
|
|
|
* Default (usually fits): `node ./ves.js`
|
|
* Or for larger configuraitons: `node --max-old-space-size=8192 ./ves.js`
|
|
|
|
## Installation
|
|
1. Grab the latest release source code (or just master source code) and extract it to any directory.
|
|
2. Install the latest FFmpeg versions for your platform that supports libvmaf (or built it yourself):
|
|
* Windows: Extract [this archive](https://github.com/Xaymar/video-encoding-samples/releases/download/0.1.0/ffmpeg.7z) into `ffmpeg/`.
|
|
* Linux (apt): `apt-get install ffmpeg`
|
|
3. Grab the recommended model (see requirements) and place it into `ffmpeg/vmaf/`.
|
|
* It is possible to use different models, however this model has so far given the most accurate results.
|
|
4. Put any source video files in `videos/`.
|
|
* Videos must be properly tagged or they will be treated as bt709/bt709/bt709/tv.
|
|
* Video files must be in .mkv format.
|
|
5. Adjust the `config.json` file to your needs.
|
|
6. Run the tool.
