Shellscript to create HTML5 <video> MP4/OGV/WEBM/FLV/JPG versions of any video. The size, bitrate, cropping and sharpening can all be defined at the top of the script. Requirements: ffmpeg with libx264/libvpx/libtheora codecs (can be installed via homebrew). And flvtool2 (sudo gem install flvtool2).
