problem with dvd video when played on TV - using nerovision

[boochxo]

I'm using NeroVision 3 to create dvds from avi files. Everything worked (including when played on my computer) until I tried the finished prodouct out on a dvd player hooked up to my tv. For some reason the picture seems zoomed in or cut off on the sides. I had the same problem when using video out through my computer but there was an option for zoom control that fixed it. Is there an option in Nero that I am overlooking? Any help would be appreciated. thanks!

It's not a problem, it's called overscan, and it's normal.

So is there a way to make the video display correctly? There's got to be something to do because not everyone is having this problem.

[Matt D]

Like I said, it's not a problem. It's a deliberate technique used to cut off any warping or distortion towards the edge of the tube. Every TV show, VHS tape, Laser Disc or DVD is also "cut off" on the sides as well as the top and bottom to a lesser degree.
Anyhoo, you can "fix" this if you must by adding in a black border to the edges, but this needs to be done when encoding.

so, how exactly do i add black bars?

[guns1inger]

Dont know if Nerovision can do it. Tmpgenc has an option to centre and create a border. Otherwise you can resize the video in VirtualDub or your editing software and overlay this on black. Do a search for overscan and virtualdub - I have seen scripts posted to do this.

I may end up trying to add black bars but after i think about it more there seems to be something wrong about this explination. My first problem is that not all files put on dvd end up cuting off the edges. Don't you think overscan would effect all files instead of just some? Also someone explained that all movies have the edges cut off yet they look the same on the computer as they do on the television. When i play the dvd made with nero it looks correct on the computer but not the tv. My last problem is that there doesn't seem to be too many people out there with this problem. Obviously more people would be complaining about such a problem since it is quite noticeable. Any more comments or help would be appreciated. thanks.

I hate to disagree, but overscan is normal. I have been converting video for years and I will tell you that video on a monitor looks different than on TV either the video will be cut and so you will see a little less on TV or you'll see that there has been a border added on a monitor which a TV will cut off. Look at video with a logo on it, it will be farther from the side of the screen on your PC that it is on TV because your TV will cut it.
You don't have to believe me, if I was yanking your chain here someone would've pointed that out.

In NVE3 at the bottom of the menu there is an option called Video Options..in there you will find choices to change aspect ratio,transcoding quality,resolution size,bitrate etc....
1.aspect ratio 4:3-works great on majority of TV's
2.Quality setting Custom
3.Sample format-automatic
4.Bit rate-as high as possible without going over the dvd limit
5.resolution-720x480(CCIR-601 D1)
6.encoding mode-High Quality(2Pass VBR)
7.audio format-LPCM
and always set to NTSC if you live in the USA..even if it recommends you switch over to PAL because more PAL files exist than NTSC..
been using these setting for awhile without ever a problem..hope this helped

Here's an example of overscan for you boochxo. The first pic here is how the image appears on a TV. This is not from a disc, but as the image appears right off the satellite.



This one here is how the same exact frame appears on a PC monitor. Quite a difference, and if you had only seen the footage on your monitor you'd wonder what the hell was wrong.



Here is another same frame comparison. This is from the commercial DVD Prisoner of Azkaban. First image is on a TV.



This is the same frame again on a PC monitor.



I will agree with you that sometimes this CAN be a problem. If you're losing the end of credits or subtitles, clearly this should not be so, and adding bars will get the video back onscreen where it's supposed to be. In most cases though, as above, the overscan is 100% normal and does not need to be fixed.
