avi conversion help

[justme764]

Hello,

I have searched and searched and can't find what I'm trying to do.

I have an avi file that is in widescreen format. Is it posible to convert it to full screen so it looks nomal on my tv. I have tried many differnt ways (TMPEG full screen keep aspec ratio, fullscreen, no margins etc...) and it either leaves it in widescreen or cuts off the side of the picture. Any help would be great and thanks in advance.

You can stretch it to fill the 4:3 screen, but everything will be tall and thin. I don't call that

full screen so it looks nomal on my tv

.

If you really want to do this, in TmpGenc, have you tried Video arrange method 'Full Screen'.

I can't be 100% sure this is the right setting as it is not something I have ever wanted to do

[athlon_rules]

You set arrange method in tmpgenc to full screen and then you simply start cutting out stuff from the left and right of the picture until it looks right.

but why why why

totally destroys everything doing that

..or load your avi into VirtualDub, and use the crop and resize filters in there, before frameserving it into to TMPGEnc.

However, I have to agree...

but why why why

You'll be losing a lot of the picture at the sides, or stretching things way out of shape.

Hello again,

Thanks for replying. You ask why well to be totally honest I don't know why. It just seems that when I make and svcd and burn it the sides of the picture are cut off when I watch it on my tv. if I leave it as is its all there but there is the black margin at the top and bottom on my tv. I'm really new at this an maybe I'm not asking it right. I just wanted it to fill me tv screen and have the whole picture there. Thanks for any help again.

If you don't have a widescreen TV (and I don't either) - you'll get black borders at the top and bottom with all widescreen movies.

Movies, in general, are shot in widescreen - as this is the shape of the screens in cinemas (and supposedly fits the way that human vision works better than 'full screen' aspect ratios).

Movies that are released in fullscreen (or broadcast on TV in fullscreen) have generally been converted from widescreen by pan and scan.

This means the studio has actually gone through the film choosing which bits of the original can be 'chopped off' without losing the important action / details - different bits are cropped in different scenes according to what's going on onscreen.

If you try and do this conversion yourself, you'll be just arbitrarily chopping off the sides of the image - even if that's where the important stuff is going on. Or, you could stretch the whole image vertically to fill the black borders. This will really mess up the image - with people looking too tall and thin etc..

In essence, you're best to just put up with the black borders in widescreen, or buy a widescreen tele!

You'll find widescreen store-bought DVD's will do this also on a 4:3 ratio (standard non-widescreen) TV screen.

There is another thing which you may be noticing - called overscan. This is where TV screens chop off a small portion of the image on all sides. This just happens on more-or-less all TVs.

Some people try and account for overscan by resizing their video streams during conversion (e.g. in VirtualDub, before frameserving into an encoder). People do this especially to prevent subtitles disappearing off the bottom of the screen. This topic has been well covered - do some searches on the forum.

Ahhhh,

Thanks for the great explanation. It makes much more sense now.

I also want to say thanks to all the great people here who make the guides and offer so much help to us newbies. I can make an svcd with menus and chapters that looks good and works on my dvd play.
