Video aspect ratio and scale
by GPGAgent from LinuxQuestions.org on (#57Z1R)
Why is a 4:3 (1.3333) aspect ratio dvd have a scale of 720x576 (1.25)?
When I take this video and use ffmpeg to create images I have to specify scale=720:540 like thisCode:ffmpeg -i x.VOB -vf "fps=1/3,scale=720:540" IMAGES-%05d.pngIf I don't the images are slightly incorrect and you can easily see this.
