How To Stretch 4:3 Picture Ratio to 16:9

[kerrex_2006]

I'm trying to figure how to convert 4:3 video to a 16:9

I used to do it simply do this by putting the 16:9 option for Windows Movie Maker when we had Windows XP, but Vista won't do that, and instead puts these distracting bars on the sides.

To keep the aspect ratio you need to add bars on the sides if you don't want to crop parts of the image when viewing 4:3 on a 16:9 screen. The other option is too crop top and bottom of the 4:3 picture and zoom into the picture to fill the 16:9 screen, but then you will loose picture information (unless the original video was letterboxed).

This avisynth script will warp stretch the 4:3 video to 16:9

myVideo=AviSource("D:\video\43video.avi")
wi=Width(myVideo)

fourthree2sixteennine(myVideo)
lanczos4resize(int(he*1.7777778),he)
