Convert any video to WebM and MP4 for HTML5 video

video-to-web.sh

#!/bin/bash

# This script takes any (high resolution) video file as input and converts it to WebM (VP8 & Vorbis) and MP4 (H264 & AAC) for HTML5 <video>. For each format, it creates a high quality (`-hq`) and a low quality (`-lq`) version.
# ffmpeg has to be installed, see http://docs.sublimevideo.net/encode-videos-for-the-web for more instructions.
# Usage: videoToWeb.sh <inputfile>

# This is heavily inspired by

# - https://github.com/mickro/video2html5/blob/master/video2html5.sh
