Convert 592x352 xvid to 16:9 dvd?

[asa]

I have 592x352 xivd file and I want to convert to 16:9 dvd.
You see the ratio is smaller than 16:9 so after a while I found out to get source ascept ratio we have to convert to 4:3 dvd spec but we will have big black bar=> waste some bit rate. If we set 16:9 spec we will black bar in the right and left of the image.
To get proper ratio I have cropt the source 10 pix both the top and bottom then use res 704x480. I want to convert the file to 16:9 video with full res image
So does anyone has any suggestion, I just rookie in dvd creation.

Hi-

Your AVI has a 1.68:1 ratio, so I assume the original movie was probably 1.66:1, and whoever encoded it for AVI did some cropping to minimize AR Error. If you're encoding for 16:9, then it's supposed to have some black bars on the sides, as you discovered.

Anyway, use FitCD for the job of finding the crop, resize, and addborders. You didn't say how you'd be encoding, or how you're going to frameserve, or even if you're going to frameserve, but FitCD gives me this using ITU Resizing (less black bars):

Crop(0,2,592,348)
LanczosResize(688,480)
AddBorders(16,0,16,0)

You can do it without cropping, but the Aspect Error goes up fairly high.

Ordinarily there is some benefit to encoding 1.66:1 movies for 16:9, but since you're starting with a 592x352 AVI, you may as well encode for 4:3. There is no benefit to encoding for 16:9 in your case. Without ITU resizing and 4:3 encoding, no cropping is necessary:

LanczosResize(720,390)
AddBorders(0,45,0,45)

The AddBorders numbers should probably be even numbers, so I'd modify it to AddBorders(0,44,0,46).

thanks manono for your help, so the source has been crop as I think.
I will crop it and encode to 704x480 as I did before for better 16:9 ratio because I want to watch this in 16:9 tv and honestly I don't like the black bar at left/right side.

Well, not very much. Maybe a couple of pixels on the top and bottom.

OK, I can understand wanting to do it for 16:9 for your 16:9 TV set, but all or almost all of the black bars will be hidden by the overscan anyway. When I watch 16:9 DVDs of 1.66:1 movies, there's very little black bars showing on the sides. You have to train yourself to enjoy movies in the intended AR. You have a 16:9 TV, but only a minority of movies are 1.78:1.

In fact, aside from TV programs of recent years, the vast majority of programs and movies do not fit exactly inside a 16:9 frame without some form of vertical or horizontal bars. If you bought your widescreen TV believing you would never see black bars again then you were ripped off by the salesman and should go and demand your money back. It is obviously not fit for the purpose you bought it for.

I still have a 4:3 TV with widescreen switching, always watch movies in the original aspect ratio, and haven't seen a black bar in years. If you are watching the movie, you shouldn't notice them. If you are watching the black bars, the movie must be really, really crap.

Yes, I dont like the bar at side because when I try the output through video out port to my tv I cant see the bar quite thick perhaps the pc port output the full res to my tv . I know there is very little film is 1.78:1 and even some of them have been converted to 1.78:1 for dvd while the theatrical version is anamorphic.
Anyway thanks for your help very much

Right if I watch the bar so the movie is really crap , if we don't want to see the bar we had better buy a projector, turn of the light and we will have a whole room of black bar
