The movie is too big for my tv

[d3adpool]

Hi,
I've been trying to convert some AVIs i got on my computer (2 videos, 640x352 - 1.82:1, 23.97). First of all my problem, the encoding runs smooth, i've got all the avisynth scripts (v2.55) ready, and in my computer everything is sweet. But when i try to watch the authored DVD in my standalone the screen is bigger than the tv screen. Now, i'm pretty sure the problem is with my tv (kinda old, not even flat) but anyway.... the aspect ratio is 4:3 Fullscreen (comes from a TV source). Now in my avisynth for the resizing is something like this:

avisource("H:\AVIS\source1.avi")
BicubicResize(720,416)
AddBorders(0,80,0,80)

now if this avisynth is wrong, then i'll just happily re-encode everything... but i really think the problem is with my TV. Now, is this even possible? The problem being with my TV? Or am i just really lame with encoding? (BTW, the problem might be with the MPEG-2 enconder i use that trial CCE...

also, i'm just posting here because i followed the guide to the letter and it didn't turned out as expected... thanks in advance

someone else can correct me if I'm wrong but I believe your problem is the 416

that should be either 720x480 (NTSC) or 720x576 (PAL) (sometimes it can be 702) your 1.82:1 is the DAR, not the physcal AR...

I'm somewhat impressed that 416 was excepted.. what app did you use to author the file?

I think what you are talking about here is the overscan inherent in CRT televisions. It's not possible to make a DVD that is "too big", if it displays at all it will be within the frame. But CRT displays lose about 10% to 15% of the picture to overscan.

thanks for the quick reply.

the issue is the overscan, last night after i posted this i went to friends house with a flatron and everything was allright... my real problem was with the fact that the movie is fullscreen so i lost something. gotta buy a new tv.

thanks again ^^

EDIT: also, this 416 (wich also bugged me in the begining) seems to be correct. i used DVDAuthorGUI for the Authoring

Hi,
I've been trying to convert some AVIs i got on my computer (2 videos, 640x352 - 1.82:1, 23.97).

avisource("H:\AVIS\source1.avi")
BicubicResize(720,416)
AddBorders(0,80,0,80)


640x352 = 1,82:1

for DAR 4:3 resize to
BicubicResize(720,422)
AddBorders (0,77,0,77)

for DAR 16:9
BicubicResize(720,562)
AddBorders (0,7,0,7)
This would be the case if you would make a PAL Dvd
77+77+422=576
7+7+562=576

But... you got a 23,97 fps video -> NTSC (incase you didn't covert it to 25fps)

so i think you should use :
BicubicResize(720,352)
AddBorders (0,64,0,64)
352+64+64=480
But check Step 3 (http://www.doom9.org/index.html?/mpg/avi2dvdr.htm) of this guide.

If you have a relatively new TV, you can usually adjust your horizontal and vertical overscan in the service menu, if you can get to it (and if it exists).

Sometimes there are tricks, like holding down Menu on the TV and/or on the remote. You can also get a programmable remote from radio shack. Provided you can google-up the proper codes for your TV, you can get to the service menu pretty easily. Just be careful not to mess up your aspect ratio, and get a disc like Digital Video Essentials to calibrate properly. See avsforum.com for more info about various displays.
