Overscan. Need help! Please...

[Kalle]

Hello everyone.

This is my first post here ever so I'm as big a newbie you can find


Anyway... Over to my problem. I've been trying to burn a movie into DVD (and SVCD) for 1 week now and I have one HUGE problem. When I look at the movie (this is a homemade on so it's legal) on my comp everything is fine. But then I put it in my DVD-player (Pioneer DV-454) and play it it doesn't show the whole picture. Parts in every direction is left out. I've uploaded a picture. I shoule be able to see everything but only what's inside the red fram is shown on my TV. I've also tested on anotehr DVD-player and another TV. They are all the same. But I did recently discover something interesting... Then I set my DVD-player to 4:3 (Letterbox) I can see everything verticly but not on the horzinal line.

I've tested almsot all DVD Authoring programs there is and I've tested some with DVDPathcer but no matter what I do I still can't get it right. So please can someone give me a simple guide? I use Premiere 6.5 (and the MPEG encoder version 1.2 in it) if that helps you to help me.







EDIT:
Changed the subject.

This is a common problem. what i personaly do to solve it is, before encoding I use avisynth, for example:

loadplugin("C:\AVSFilters\Decomb.dll")
Telecide()
Decimate()
addborders(10,10,10,10)
lanczosresize(720,480)
adding borders then resizing to the proper aspect ratio should solve your problem.
Other people may use other methods, but this works very well for me

good-luck

This is the age old issue of T.V. 'OverScan'. This is why you have 'TitleSafe' and 'Picture Safe' frames in DVD authoring software, so that you do not fall foul of this problem when creating titles and menu graphics/buttons.

There is nothing actually 'wrong' with your television, it's just that you need to take overscan into consideration when authoring your video projects in future.

Thanks to both of you!

About Avisynth... I have installed it now but I have no clue on how to get it to work. Loadplugin? Where do I do this? The documentation on VideoTools is extremely bad.


EDIT:
I've done some reasearch in the area and tried some things. But this is still WAY to advanced for me. I would really appriciate if someone could make me a working AVS file and tell me what to edit to get it to work on my MPEG files (It does support MPEG right?). My e-mail is karl@merafilm.nu

Thanks.

I've gotten some idea on how to use AVISynth and I've downloaded a program called VirtualDub. Is this the same thing but with a graphical interface?
I really suck at programming so any hint would be very appriciated.

And how thick does the border have to be to show correclty on a PAL system?

[mats.hogberg]

VirtulalDub could be called "AviSynth with GUI" but isn't really. But they share many of the same functions like resizing, adding subtitles etc.
There's no defined overscan standard - this seems to vary quite some from TV to TV.
What is your source material? MPEG? AVI?

If you can open your source in VirtualDub, use the resize filter, then frame serve to your mpeg encoder. (See guides here on frame serving.)

I use a muxed MPEG-2 file with a variable bit rate. I use PAL format. I tried using VirtualDub with that file but it couldn't read it. And then I read something about only reading d2v files so I used DVD2AVI to make one. Then I ran out of time and had to run to school

[mats.hogberg]

There is a mpeg2 capable version of VirtualDub that ought to do the trick!

Thanks!

I'll try it the moment I get home.
