ELTA 8883: zoom to much

[manzu68]

I usually encode (in xvid) my movies with keeping the source size without the black border arround it. It generelly bocomes 720*288(or whatever). Recently I noticed that my ELTA 8883 zooms to much off when I play the movies on my 4:3 TV. To find out how much it zooms off I made a couple of samples with adding border on the left and right side. Believe it or not even I added 35 on each side I could not see the borders on my TV. When used 40 on each side I began to see the borders.
That means about 11% of the movie I cannot see.:eek:

Does it depends on my tv? I wonder how much of the dvd-films it zooms off.

I doubt it's the Elta doing this; have you checked how much your TV cuts off from over-the-air material? All TVs cut off a certain amount of picture at the borders - some more, some less...

np: Shadow Huntaz - Frenches (Corrupt Data)

Heres a picture where you can see how much the elta cuts from a movie with 704x528 pixels. The green square should be as big as the yellow and red.

Its only a few pixels - your TVs overscan area is responsible for the rest.
Its not unusual that you can only see the red square and parts of the yellow on a TV.

However, manually adjusting the picture size would be a nice feature for a dvd player.

manzu68: most 'classical' tv sets active image area is about 10% smaller than full video frame, so it is not about elta (for example: subtitle safe area is usually defined even smaller - about 20% of the full frame).

All right, I guess I have to live with the overscan the TV does. So what are the options do I actually have?

If I want to see the whole frame (the one film director wanted to show) I have to encode with 640 width+ 40 black borders on each side.

Get a newer TV.

Encode one for TV and one for PC.

Another option would be zooming out. Elta has already the zoom feature but when it zooms out it makes the frame size 1/2 of the original. But that is too much. I think if I could zoom out 1/4 of the original then I could bypass the tv's overscan problem. Let’s wish that Elta adds the 1/4 zooming feature in next firmware.

Has anyone any better ide?

Why do you think it's so much of a problem? Anything you watch on a CRT TV is going to be overscanned, and it's not like there's anything interesting happening that close to the edges that you're going to miss.

Unless there's badly made subtitles...

Have same problem but not with all movies!
Depends on resizing.Sometimes it cuts much more on left side than the right one.
Try with original DVDs and others DivX encoded at different resolutions, you will be surprized. I was!
Its hard to explain why it cuts more one one side. I donT think it's only an Elta issue.Mpeg4 players still imature on all aspects.
