Video To DVD

ffmpeg -y -i ihtsbih.webm -aspect 16:9 -vf scale=720x306,pad=720:480:0:87:black -target ntsc-dvd -q:a 0 -q:v 0 output.mpg

Maintain Aspect Ratio

• http://andrew.hedges.name/experiments/aspect_ratio/

original height / original width x new width = new height

• Get new height
• Scale video from 720x480 (if this is your output)
• So if new video is supposed to be 480 high but to maintain aspect it needs to be 306 then scale to 306 like above and add two 87 pix bars
