In your case it seems that's how the original video was encoded. A lot of encoding software will actually try to save you from yourself by preventing that distortion from happening, so if you encode a 4:3 picture while specifying a 16:9 output aspect ratio, the software may automatically include/add pillar boxes to the sides, giving you an 'overall' 16:9 aspect ratio as you requested, while keeping the original 4:3 video intact within. You can change the dimensions of the video itself by removing some of it when encoding, but the shape of objects in the video which remains should never change as any change is a distortion of the picture. The bottom line is you don't really want to change the actual picture aspect ratio when encoding. In fact you can set your TV or display to zoom in and see what is happening. The only (bad) ways around this are either to zoom in, or distort the image. How do yo u fit something 1440x1080 into that? It fits perfectly with pillarbox bars.

Think of it as a window with size 1920x1080. Sorry I'm doing a poor job of explaining it.Įven if you cropped it, encoded it as 1440x1080 (cropped the pillar box sides off), when you watch it on a 1920x1080 display, the display will add the bars back. It's not something the encoder did to prevent it, it's just that you are watching 4:3 content on a 16:9 display. I don't want to spend a lot of time circling around the point without learning the issue. I just wanted to learn the cause behind it.

Do you understand what the problem is now? I believe it's something the original encoder did to prevent it.Īnyways, it's now a huge issue. Let me put another way, even when I tried to crop half of the picture out it would not let me. Interleave, duration : 24 ms (0.58 video frame)

Why? Which field did the original encoder modify to prevent changing of its display aspect ratio? How if there is any way to change it?įormat settings, Matrix : Default (H.263) Regardless of which software or method I used, it will not allow me to change it. I have this video that I wish to change its display aspect ratio.
