Chaning a 4:3 DVD into a 16:9 DVD?

[bigscaryrobot]

I have a few trailers that I ripped from a DVD that are 4:3. Is there anyway to make these 16x9?

thanks

You mean with black sides? You can't restore the cropped sides of the video.

If you put a 16x9 header on a 4x3 frame you get a horiz stretched 4x3 image.

Do you mean letterboxed 4:3 ?
Crop the bars then resize to full frame. I believe 60 lines top and bottom will match NTSC 16:9. It's not true anamorphic, and you run the risk of artifacts due to the resize, but give it a try.

i mean take a film thats OAR is 2.35:1, but the DVD is non-anamorphic and make the image so it cuts a little of the bars off at the top and bottom so the image looks proper on a 16x9 screen. Is that posible?

If you have your DVD and TV set up correctly, it should look fine anyway. My first response will give you faux-anamorphic, but it wont enhance the output like true anamorphic would. Your player should play these as 4:3, and your TV should be able to zoom to fill the screen to the left and right edges.

Hi-

...but you'll need to convert to AVI.

No you won't. An MPEG encoder, such as CCE, can take the AviSynth script file directly. However, as guns1inger already stated, there's not much point in converting it to 16:9. It's only going to do what your TV or DVD player Zoom is going to do. However, if you still want to do it, FitCD can give you the crop and resize values to convert from 4:3 to 16:9.

If I want to play a few 16x9 clips and then play a 4:3 clip, the zoom would screw up the 16x9s, so I want them all to be the right size.

So now I understand, they are 16:9 but are palying 4:3.... I think thta's what you mean.

The aspect of a video is determined by the header in a video file or the ifo file on DVD. 16:9 and 4:3 are both the same resolution, commonly 720x480.

You need to use authoring software that supports 16:9 - or use ifo edit to change the ifo file. There's guides listed below, click the link.

im not sure we're talking about the same thing. Let me lay it out so we're clear.

I have one clip that has an aspect ratio of 2.35:1, but it is not anamorphic. I want to make the clip so the 2.35:1 bars wil look right on a 16x9 screen.

Does that make sense?

Thanks

So the heigth is shorter than a 16:9 correct? If you play it full screen on a 16:9 screen they are slighlty stretched vertically?

Here's one way:

LanczosResize(544,480,0,2,720,476)
AddBorders(88,0,88,0)

That'll make it 16:9 but without zooming it, so it won't look any worse than it already does on your HDTV. It adds black to the sides. To do it by cropping from the top and bottom, without touching the sides (in effect zooming it), to do it accurately you have to know the exact amount of black around the video on all 4 sides. Here's one solution, though:

Crop(0,48,0,46)
LanczosResize(720,480)

You could easily have figured the same thing had you taken my suggestion about using FitCD.
