Still hunting GRIPCrop overscan data
 

I've tried overscan 0,1,2 and different screen settings in TMPGEnc, but I keep getting bands on the top and bottom. This is a 4:3 source, from a dvd. How do I get full screen back?

Hi nicksteel,

Your original DVD doesn't show black borders :?:

The original does have very thin borders on all sides. The copy has 16x9 kind of borders and no side borders.

Also, which WinDVD package do I need? There are several of them on their site. I use Windows98se.

Get WinDVD 4.0

Still GRIPCROP problems with SKVCD.
 

[quote="nicksteel"]Rechecked source. There are no borders, just ntsc 29, 4:3. When I remove Gripcrop, goes to full screen in TMPGEnc. With Gripcrop, no settings in TMPGEnc result in full screen. Without Gripcrop, the file size increases a lot.

Re: Still GRIPCROP problems with SKVCD.
 

Hi nicksteel,

If your source is 4:3 fullscreen, I see no need to use GripFit.
Just remove GripCrop, GripSize and GripBorders from your script, and put back the BilinearResize.
If you really want to use GripFit then change this line:
GripCrop(352,480, overscan=0)
to
GripCrop(352,480, overscan=0, source_anamorphic=false)

Thanks, Mauddib! Worked like a charm with revised statement.

Tip: If you use MoveStacker to generate your script it will detect what kind
of source you have and will set the GripFit parameters correct. 8) :wink:

Hi Muaddib,

Where can I get MoveStacker ?

Hey man! Where have you been!? 8O

Re: Still GRIPCROP problems with SKVCD.
 

I do agree and it works just perfect. Only one small difference between
what muaddib posted and MovieStacker when I used it for generating
4:3 .avs script

I didn't touch anything just loaded kvcdx3 template after loading d2v. The
movie was encoded just fine and I'm playing it without problems.

So what is the difference between "overscan=0" and "overscan=2" in
GripCrop function?

I have the same problem with a Divx.

On Windows Media Player it has Borders on top and bottom but on Power DVD 4.0 XP there are no borders.And now we have the Problem.

Even If I use the Line,there are still borders.

What am I doing wrong???

@JoZ
overscan=0 you get no blocks tv overscan
overscan=2 you get two blocks tv overscan
that's it... :wink: :mrgreen:

@Bchteam
You are trying to play a DivX with PowerDVD. If I remember PowerDVD don't play anamorphic DivX with correct aspect ratio. It vertically stretches the image all the way. Use WinDVD or ZoomPlayer to play it.

hi Bchteam,

This is assuming you are divX'ing around, BUT.. those MPEG-1 clips play
excellent in this app too !! Take advantage of 352x480 encodes (if you
can) for the "Fullscreen 4:3" viewing on PC Monitor.

PowerDVD and WinDVD cannot display divX encodes correctly as mauddib had
described.

I have ben using Zoomplayer for a while now (mostly to test my divX
encoding and stuff) but I do have some suggestions when using..

* First, D/L v2.90 (or higher)

* If your encodes are 352x480, press the R key on keyboard until
..you see the "Fullscreen 4:3" display. This is the correct AR to use for
..re-stretching those 352x480 encodes to FullScreen on your PC Monitor.
..Quality is fantastic, PENDING upon your encode of course.

* If your encodes are Widescreen, and depending on your cutting off the
..black bars (I cut them completely out via vdub) Unfortunately, I don't
..really like using AVIsynth, only because I just don't get all those dementions
..that are used in the params of different functions in AVIsynth, AND,
..because I can't see the changes in a video window as I can in vdub.
..That's about the only reason so far, that I use: AVIsynth -> vdub -> TMPG
..in some of my encodes. Anyways.. back to issue..

* after you've cut your bars, and size your encode, when you do finally play
..your MPEG-1's (or divX) in Zoompler, for Widescreen, press the R key
..until you see the "Widescreen 16:9" or if your encodes (MPEG-1 or divX)
..are really shollow (2.35 or something) then select the "Custom (2.35:1.0)"
..and enjoy really good quality play-time. It's fantastic viewing quality.

Unfortunately, I don't know what the actual key-board short-cut keys are to
all these Aspect Ratios (AR) but if anyone does, please do post.. cause I'd
sure love to use them when I'm quickly switching from one AR to the next :wink:

And remember, when you do Widescreen projects (MPEG-1 or divX) and cut the
boarders off complete (that's my other recommend) remember to set the AR in
Zoompler for "Widescreen 16:9" or "Custom (2.35:1.0)" or for 4:3 encodes,
set to "Fullscreen 4:3" and you'll love the play quality (pending your encoding
skills and source quality)

Another good reason for 352x480 divX encodes, is because you can re-encode them
w/ greater accuracies for an MPEG-1 (kvcd etc) and STILL maintain that
AR viewing.

-vhelp

Hi vhelp,

I don't know about the short-cuts but when I want to change the AR I just right-click on the movie and select the "Aspect Ratio" menu. There you will find all the ARs that ZoomPlayer can handle. Btw, with version 3.0+ you can select "source aspect ratio" and any anamorphic DivX (16:9, 2.35:1 or any other crazy divx AR) will play with the correct aspect. :wink:

hi mauddib,

Zoomplayer v2.90 ..
I have re-researched your "source aspect ratio" but it doesn't
seem to work for my divX encodes when I do 352x480 encodes. Also,
if I encode some divX that have WideScreen, and I take out the boarders
for better bitrate control/quality, the above doesn't work. That is why I
was saying to adjust it manually instead, to be on the safe side.

Since you have version 3.0, be a pal, and double-check this out for me
with your version, but D/L'ing a sample divX clip I did. I maintain a
pool of daily or weekly or so, sample of my work, over on dvdrhelp. It's
called:

VHELP's Samples - updated daily or so... LAST- 03.12.03

I was planning on U/L'ing another sample (16:9 one) but I'll wait till get that one, that is, if you so choose to test this out for me.

Thanks.
-vhelp

Hi vhelp,

I got that sample, and it's not anamorphic. It's a 352X480 mpeg (4:3) sample. It's supposed to be played with 4:3 aspect ratio. It has to be stretched much more horizontally then vertically, and will never look right with "source aspect ratio".
The "source aspect ratio" option is a 1:1 stretch till the film borders reach the screen borders. All anamorphic DivX that I have here are encoded with a correct 1:1 aspect ratio, and all them look right with this option.
Try it with an anamorphic DivX (no borders!). I'm sure it will work. :wink:

Note: Did you try the Media Player Classic 6.4.3.1 by Gabest (the same author of the VobSub filter). It's only 530kb and makes a very good job with aspect ratios (divx and mpeg). You can get it here.

Hi mauddib..

Now you got my curiosity going w/ "aspect ratio" (AR) and I'm not wondering
how I my "factor" into my MPEG-2 and divX encoding when I use cutting of
boarders etc. in my encodes. I don't use mplayer v.xxx because i've many
problems like crashes and things, plus, I didn't want to get stuck w/ the latest
version "locking" you into it, short of re-intsalling Windows 98 for an older
version. Currently, I've installed many drivers/graphics/drivers/video/soft..
apps and things that installed many different versions of mplayer V.xxx versions
to the point now, that my pc (mplayer) acts up on certain encodes I do, and
crashes my system to a re-boot. So, I don't bother w/ mplayer and instead, I
use Zoomplayer, and my PC monitor viewing is fantasic (so far)

So, I have question for anyone.. how I might be able to encode my clips (divX)
but with a 1:1 AR, so that my encodes play properly in ANY software player app,
using vdub or AVIsynth filter techniques ??

Thanks for your responses :)
