# video2gif

![sample gif file generated](sample.gif)

A batch script for converting video files to GIF using FFmpeg on Windows.

## Installation
* Clone the repo
* Install [FFmpeg](http://ffmpeg.zeranoe.com/builds/) for Windows.
* Make sure that the path to `ffmpeg.exe` is configured in your system environment variables control panel or that you run the `gifenc.bat` file in the same folder as `ffmpeg.exe`.

## Usage
```
gifenc [input_file] [width_in_pixels] [framerate_in_Hz] [palettegen_mode] [Dithering_Algorithm]
```
Always make sure the current directory is the same as the one the video file is in, otherwise the conversion will fail.
## Options:
```
Palettegen Modes:
      1: diff - only what moves affects the palette
      2: single - one palette per frame
      3: full - one palette for the whole gif
-----------------------------------------------------------------------------------------------
Dithering Options:
      1: Bayer
      2: Heckbert
      3: Floyd Steinberg
      4: Sierra2
      5: Sierra2_4a
      6: No Dithering
```

## Examples:
```
  gifenc sample.mp4 300 15 1 1
  gifenc sample.mp4 600 10 2 3
  gifenc sample.mp4 350 13 3 1

```
