Television Overscan

Shibblet · #1 10-27-2005, 08:45 PM

Hey, I made a few KVCD MPEG files that test the overscan blocks on your television.

I have them at resolutions of 352x240, 352x480, 480x480, 704x480, and 720x480.

All you do is burn them to a VideoCD (non-standard) and play them on your television. The MPEG file will produce a black background with a blue border. When you see the blue border, you'll know the exact overscan resolution of your Television at the MPEG resolution in question.

However, I have no web-space to upload them to for people to download... any assistance in this matter would be greatly appreciated.

Very good Shibblet

Just tested them on my PC.
Time for a burn on CD to see what my overscan cut off point is

I enjoyed it too much

Could you explain how exactly you "encoded" these mpeg videos with that "action"? I mean, avs scripts, etc ?

Shibblet · #7 10-28-2005, 01:00 AM

Well... I'd kind of take the mystery out of it with an explanation. But it's a boring tale actually.

I used mathematics and Adobe Photoshop. That's it.

Could you make these promising samples in Pal resolution, please ?

That's a great idea, you had.
Thanks a lot.

Shibblet · #9 10-28-2005, 01:02 PM

Yeah, I can. Give me a few more days.

Shibblet · #10 10-28-2005, 08:11 PM

Less time than I thought actually...

The PAL Overscan MPEG's are available here:

Cool. Thank you. I'll try that tomorrow.

rds_correia · #12 10-29-2005, 09:59 AM

Very nice indeed.
Thanks shibblet

.
I had done the same a few months ago with an internal avisynth function that I completely forgot

.
So this will help me a lot when I run into my friends TV sets.
Cheers mate

Very good!

jason · #14 10-29-2005, 11:20 AM

Very thanks !

Shibblet · #15 10-29-2005, 01:50 PM

No problem everyone. I just forgot how may PAL'ers there are out there. What's the matter with you guys anyway!

digitall.doc · #16 10-29-2005, 03:30 PM

Thanx Shibblet (also PAL here)

...but

... the link in mytempdir.com downloads a file that contains again NTSC ones

The rapidshare link is OK.

What's the matter with you NTSC guys!

Je, je

Thank you, again

/very low and humble voice
you forgot also that KVCD are 544x480(576)

rds_correia · #18 10-29-2005, 06:39 PM

...and also 528x480(576)

Trash 544 for TV-purposes, regarding to ITU, ... 528 is exactly the effective TV area contend of these 544. The overhead pixels of 528 will be encoded for the "nirvana"

Shibblet, thats a VERY cool testchart!

Best would be doing a DVD where every increasing step is separated as a chapter incl. the current size as typo in the middle on the actual overscan shown screen. So a user can step forward till the area gets visible, so he can easely write down the individual size needed for HIS TV set

And .... the user can find out if HIS SAP is ITU compatible at 544, 528 etc.

All my tests proove me the opposite and if you permit, I wish to see that with the overscan test Shibblet did.

Try the 704 and the 720 one and you can see that the green (or blue) border appears at the exact same number of pixels. This is at least on my two TV set.
Stange, isn't it ?

Note : The DVD, user can do it if needed. And people that have SAP that can read raw MPEG2 files gain precious minutes
