Naive-FFmpeg
============
A simple command line FFmpeg wrapper for converting videos to .mp4 or .webm (in parallel).
Set quality and scaling with simple parameters. The formats determine the codecs: mp4 for x264 and mp3lame; webm for VPx and vorbis.

Requirements
----------
* [FFmpeg](http://www.ffmpeg.org) installed
* [Bash](https://en.wikipedia.org/wiki/Bash_(Unix_shell)) shell (for Windows users e.g. Cygwin)
Usage
----------
Multiple files can be converted and scaled easily in parallel.
E.g., to convert a folder of 1080p .MOV videos to 720p .mp4 (with x264 encoding) in parallel using at most 4 threads (e.g. quad-core), simply excecute in Bash e.g.
` $ naiveffmpeg -mp4 -quality high -scale 2:3 -parallel 4 "*.MOV" `
or using the default parameters (-mp4 -quality med -scale 1:1)
` $ naiveffmpeg -parallel 4 "*.MOV" `
The program creates a new thread for every video file. The quality (low, med, high) determines the compression rate which has been optimized for the encoder type and video resolution.
Output example:
` $ naiveffmpeg -mp4 -quality high -parallel 7 "./*.MOV" `
```
