Video Compressor for Web

It compresses a single master video file in different sizes and bitrates for web using FFMPEG. It works in Linux an Mac, not shure about Windows (If it doesn't work in windows, you just need to adjust the arrays).

After fighting a long time with video compression for websites I think this is the best approach. The codecs you need, the sizes and bitrates you need, correct MOOV atom position, reliable and adjustable, light videos but almost lossless in terms of human perception...

How to use it

1. Download and install FFMPEG
2. Downlad the script video4web.sh from this repo.
3. Drop into a folder the script video4web.sh and your master video file (let's call it master.mp4 from now on)
4. Edit video4web.sh and set the sizes, bitrates and codecs you want to export your video to:

    #codecs
    h264_codec=true
    vp9_codec=true
    vp8_codec=false

    #bit rates
    q[0]=1
    q[1]=2
    q[2]=3
    q[3]=5
    q[4]=8
    q[5]=10
    q[6]=20
    q[7]=30


    #resolutions
    r[0]=640
    r[1]=1280
    r[2]=1920
    r[3]=3840

4. Set permisions: from your terminal run chmod +x video4web.sh in the folder where you put the script and the video.
5. Run the script: from your terminal run ./video4web.sh master.mp4 filename in the folder where you put the script and the video. filename is the filename you want to give to the output files (it'll be something like filename_1280_8MB.mp4)

Depending on your output settings and your original video, it can take a fair amount of time
