Yep, that's what my neighbour told me to do. It's a pain in the ass waiting 24 hours between each coat, but I've had bad experiences taking "short cuts" before so I think I'll do what the book says this time .

@Jellygoose

Could you give me some figures from your LOTR encode? It will help me decide how to implement what you ask for. I need to know:

- All the GripXxx lines from your script
- The size of the original, unaltered frame
- The size of the existing borders as worked out manually by you
- The size of the frame after GripCrop
- The size of the frame after GripSize

That should give me something to work with .
sorry for the bit of wait...

ok, here's the script:
Code:
LoadPlugin("E:\MPEG-Tools\FitCD\MPEG2DEC.dll")
LoadPlugin("E:\MPEG-Tools\FitCD\fluxsmooth.dll")
LoadPlugin("C:\Programme\DVD2SVCD\Avisynth Subtitler.dll")
LoadPlugin("E:\MPEG-Tools\FitCD\gripfit_preview.dll")
LoadPlugin("E:\MPEG-Tools\FitCD\legalclip.dll")

Mpeg2Source("F:\LOTR2\DVD2AVI_PROJECT_FILE.d2v")
LegalClip()
GripCrop(720, 576, overscan=2, dest_anamorphic=false)
FluxSmooth(temporal_threshold=4, spatial_threshold=4)
GripSize()
GripBorders()
AvisynthSubtitler("F:\LOTR2\Subs\","permsubs.txt")
LegalClip()
Ok, I'm not really experienced with this whole resizing thing, so you plrobably have to tell me again what to do...
Source is DVD PAL (720x576)...
FitCD Tells me (overscan 0, no cropping) that the original borders are (0,72,0,72), and the video size is then 720x432...

is that what you asked for? I know there's a way to get all those information with VDub, but I didn't find it...

How does FitCD tell you that...?

I also need to know the size of the frame after GripCrop, and again after GripSize. You can do this in VDub by loading the avs then going to file->file information.

Hey Sansgrip

Tipps on drywall if you want......
Depending on how thick your mud is of course.
Your mud for taping should be thinned down...reason when it dries it will shrink ...this sucks your tape close to your drywall.
You will not have such a large hump to try and flaten out later.
If you have large gaps between your sheets this thin mud will have no backing ...gives you bubles......Use un thinned mud to fill your larger cracks ......scrape off excess mud then tape over with thined out mud .
Use thick mud for second coat ...you don't want to much shrinkage here . Tthinned mud or toping coat for last coat .....goes on thinner gives better sanding and easyer to feather edge.

have a great day

Interesting -- I did the second coat yesterday. I was having some trouble getting the edges feathered, and it was also drying real quick. Maybe I'll try thinning it a little next time .

Thanks .

Mpeg2Source("foo.d2v")
Letterbox(0, 0, 16, 16)
GripCrop(...)
The Letterbox line will make 16-pixel black borders left and right before GripCrop sees the clip. GripCrop will then crop these black borders off, effectively doing what you want. You can of course use any value you like -- 16 is just an example.
I just used the above on a SVCD conversion, and it worked _excellent_! I too had been annoyed that adding overscan blocks cause the movie to resize itself to the point where the borders added together were bigger than the visible film area. Adding the 16 pixel border to each side gave the little bit of extra compression without compromising screen size. Thanks!

You should never see borders bigger than the film area, unless your encoding a really weird AR. The most extreme I've come across -- 2.35:1 -- will, if the frame height is 480, produce an active height of ~272, meaning the borders will together be ~208.

However, I do understand what you're saying. I think I shall add this functionality into GripFit, where you can choose either to add overscan by resizing or by letterboxing.

Now, if only I could remember everything I said I would add to this next release...

Here's an idea for an overscan implementation that I'd like some feedback on before I code it up...

At the moment GripCrop measures existing borders on all edges, then crops them off. GripSize then resizes to whatever dimensions GripCrop calculated to be correct. Let's say GripCrop decided on a target width of 528: it would then have subtracted (16 * overscan) pixels from that, and decided on the new height accordingly. This is the reason that the active image is becoming so small, especially if you use 2 overscan blocks.

What if, instead of resizing to say (528 - 16 * 2), GripSize actually resized to the full 528, then simply blacked out 16 pixels on each edge? That way you'd retain a decent height for the active image area.

The other possibility is if GripCrop only cropped the top and bottom borders from the source material, leaving the left and right borders intact. GripSize would then resize to the full width (say 52 and GripBorders would black out the pixels as above. The advantage of this approach is that you lose less of the information you would see in the source material. The disadvantage is that any filters run between GripCrop and GripBorders would also process any existing left/right borders, but these are usually negligible.

Thoughts?

Not sure I see the real difference there, except where the 'work' is being done (GripSize vs. GripCrop). After using FaeryDust() on a few samples, I'd always jump for the one that is going to be faster

I'm a little confused why your second method is going to lose 'less' information... the end result is that 16pixels from each side are getting blacked out, so the picture that is visible will be the same for both.

If the source material has, say, 6-pixel borders left and right, then cropping them off, resizing to whatever width, and blacking out the borders will lose more information than resizing with those borders and then blacking out.

How about using ClipFrame in TMPGEnc with that new technique and mask the borders in TMPGEnc... wouldn't that solve the problem of applying noise and smoothing to the borders?

Nope. It would be exactly the same as how GripFit works right now, and more hassle .

Yep... I agree with kwag.
That's what I usually do with letterbox.

I also agree with you that it's negligible.
And if we use GripBorder (thatís where youíll insert the letterbox, isnít it?) after the filters, the noise that could be left by the filters in the borders will be letterboxed, and will not be transmitted to the encoder.

So how do I use Letterbox together with GripFit?
Where to put the Letterbox line?

That information can be gleaned from past posts in this thread -- but soon I shall be releasing a new version (hopefully 0.1 proper) which will offer this functionality built in.

Well, from the previous posts, it sounds like Gripborders() may be taking the place of letterbox(0,0,16,16). Is this the case?

You don't need to use Letterbox with GripFit. It's just a hack I came up with in response to a question about overscan.
