After encode, the picture is narrower on my TV?

This may be one of the dumbest questions ever asked on this forum, but I must ask since it's driving me crazy! :? :?

I was responding to another thread when Kwag corrected me and said that when creating KVCDs the option "Destination Anamorphic" in my .avs should never be used. I believe him, 100%.

My question is though when I take this line out of my script

GripCrop(352, 480, overscan=1, dest_anamorphic=true)

and replace it with

GripCrop(352, 480, overscan=1)

And re-encode, the picture is much narrower on my NTSC widescreen TV :?

If I up the Res to 480x480 it gets a little wider. If I up the Res to 528x480 it get's a little wider still, still much narrower then the origional.

I guess I thought that by changing resolution I was just change how sharp the picture looks on the screen, not how large the actual image is on the screen, and does this mean the only way to get it to playback at the same screen size as the origional DVD is to encode at the same res as the origional?

Can someone set me straight please :?:

Hi VORTECH,

You must set your input aspect in TMPEG to "Full screen".
Not Full Screen(Keep aspect), or anything else.

Kwag,

Thanks very much. I'll try a few samples and see how it looks. :)

Kwag,

I encoded a bunch of test clips at the following res.

352x240,352x480,480x480,528x480

Loaded up the appropiate TEMPGEnc KVCD template, and kept everything at it's defaults except for Video Arrange Method which I set to FULL SCREEN.

I then did the same thing, just changing the Video Arrange Method to CENTER.

I noticed no size difference when I played them all back on my Television. :?

What do I need to change to get the film to play back at same screen size as the origional.

When I view it in DVD2AVI is says

Aspect Ratio: 16:9
Frame Rate: 23.975
Film 99%
Progressive

FYI, on the back of the DVD it says "Presented in a "Letterboxed" Widescreen format preserving the 2.35:1 aspect ratio of it's origional theatrical exhibition"

Sorry to be such a pain :)

Hi VORTECH,

If you are using Moviestacker to create your resize line and borders for your .avs script, then your movie will always display correctly :!:
You are using Moviestacker, right :?:

Kwag,

Yes MovieStacker 2.0.0. I load up the vobs in DVD2AVI and then save the project. Then load the .d2v file into MovieStacker, load up one of the preset templates to get my preferred resolution, then copy and past the GripCrop line into my script.

Do I need any other parameters from MovieStacker in my script :?:

kwag	12-18-2003 09:11 PM

Hi VORTECH,

Uncheck "Use Gripfit", and try the internal bicubic resize.
See if that changes your aspect. I'm suspecting that it's Gripfit that's messing up in giving you the correct resize with that movie :!:

Kwag,

So instead of using this line

GripCrop(528, 480, overscan=2)

Use this line

BilinearResize(496, 334, 4, 0, 712, 480)

Do I need any other sizing options in my script?

Thanks

Check for "AddBorders(..)" at the end of the generated script.
If so, add that to the end of your .avs.

Sorry I noticed one more thing....MovieStacker gives me these sizing parameters when I load my .d2v

GripCrop(528, 480, overscan=2)
GripSize(resizer="BilinearResize")

I have NOT been changing the GripSize line in my script to what's above.

I was only changing the GripCrop line.

My Script was like this

GripCrop(528, 480, overscan=2)
GripSize(resizer="BicubicResize")
8O

Kwag,

Ok I do see that line AddBorders was added in MovieStacker and was also already in my script.

kwag	12-18-2003 09:41 PM

Try it without GripFit :!: :!:

VORTECH

12-18-2003 09:43 PM

Will do, thanks my friend :!: :)

Should I keep GripBorders in the script, MovieStacker does not show this although the Optimal Script does. Thanks

Nope. You should only have the Bicubic resize line, and the addborders line at the bottom of your script.
Something like this:

Code:

 



## Main section and static filters ### 

# 

Mpeg2Source("K:\RED_PLANET\VIDEO_TS\red.d2v")



BicubicResize(496, 336, 0, 0.6, 6, 0, 708, 480)

STMedianFilter(3, 3, 0, 0 ) 

MergeChroma(blur(1.5)) 





ScriptClip(" nf = YDifferenceToNext()" +chr(13)+ "unfilter( -(fmin(round(nf)*2, 100)), -(fmin(round(nf)*2, 100)) ).TemporalSoften( fmin( round(2/nf), 6), round(1/nf) , round(3/nf) , 1, 1)  ")



# 

# 



AddBorders(16, 72, 16, 72)



# 

# 

## Functions ### 



function fmin( int f1, int f2) { 

  return ( f1<f2 ) ? f1 : f2 

} 

  

#

Good, but change your resize to "BicubicResize".
In Moviestacker, select "Bicubic Precise".

Appreciate all your help. :!: :!: I will definately let you know how it turned out.

Well I know your not supposed to set anamorphic destination to true, but after much testing this has been the only way to maintain the proper aspect ratio on my widescreen television. :? :? :?

incredible

I just got in this thread so I hope i didn't miss now something.

On a new widescreen Tv Set you can choose a Zooming/Resizing.
If you just view your movie in the KVCD Letterboxed 4:3 Movie it will be shown as a small rectangular in the Middle of your Screen right??
So choose as I said the Zoom function.

You maybe will directly catch the right AspectRatio espec. for your 16:9 TvSet but on the other hand in case of KVCD encodings you will loose much CQ whle encoding and therefore much Quality.

And if I understood you right you ar a lucky one who gots a standalone wich supports SVCD muxed Streams in anamorphic state (16:9)
