Vid2Web

Transcode videos of any format into MP4, OGV, and WebM.

Installation

On Mac, use homebrew to install ffmpeg and mplayer with the necessary codecs:

brew uninstall ffmpeg
brew install --with-theora --with-libvorbis --with-libvpx --with-webm ffmpeg
brew install mplayer

Move the this folder to someplace permanent, such as your Documents folder. Open Terminal and do:

mkdir -p ~/bin
ln -s ~/Documents/transcode-web-video/vid2web ~/bin/
echo 'export PATH=$HOME/bin:$PATH' >> ~/.bashrc

Usage

vid2web -i source.mov -o outputdir/ -s 720x480 -g 30

will give you the following files, in a new folder called compressed:

compressed/
| output.mp4
| output.ogv
| output.webm
| output.jpg

Escape wildcards in -i, like \*.mp4.

Options

-i Path to source video files.

-o Path to output directory. By default videos are put in a directory next to the input called vid2web.

-s Size of the output video (like 1920x720) -- default 640x360.

-b Bitrate of the output video, in kbps -- default 1500k. A 30-second video at 1500 kbps will create a 6MB video.

-g Time at which to grab a still image, as seconds -- default 0. Use the format x5 to capture 5 images, equally spaced. Use the format +5 to capture an image every 5 seconds. Use -G to capture only images, and skip transcoding videos.
