Avisynth: using the MA-script ... suggestions?
 

I'm currently encoding The day after tomorrow (PAL) DVD to KVCD. The movie is 119min long. I'm using the MA-script with the changes Chroma 1.56 and Luma 0.25. Audio is 112kbps and resolution 480*576. I don't want to use smaller resolution than that because I'm encoding with subtitles and if I use lower resolution (352*576) the subtitles gets stretched an look unnatural in TV. How can I improve the script gaining higher cq-value/ better quality?

Any suggestion is appreciated...

Use 2 CDs, you can probably even raise the resolution then.

But if I don't want to do that? :wink:

I'm trying to fit on one CD... :lol:

Then there's not much you can do. Bilinear resizing will help but I suspect the video is already quite blurry.

The subs shouldn't look stretched if you add them to the video before resizing as they'll be resized back to their original size on playback.

According to the movie you are doing, I fear you can stop dreaming.

Re: Day after tomorrow, suggestions...
 

hello,

if you choose to use 352*576 resolution, you can easily edit the size, police, place (top, bottom...) of your subtitles with subresync of vobsub.

Hello ! did you try HybridFupp ?
http://atlas2.tgv.net/~media-video/f...t=3987&start=0
try with preset "very low" and this type of script :

Mpeg2Source("C:\KVCD\essai.d2v",cpu=4,idct=7)
GripCrop(480,576,overscan=1,source_anamorphic=true ,dest_anamorphic=false)
HybridFuPP(preset="very low",width=GripFit_resize_width,height=GripFit_res ize_height)
undot()
GripBorders()

:wink:

If things did not change, "very low" refer to the quality of the source. If you apply this on a DVD like this one, you will have a result good enought to be trashed but surely not to be burnt.

If the goal is just to put the DVD on a single Cd, use the KVCD-ULBR with a 480x576 resolution. I can swear you that you will have some space left on the disc ! ;-)

agree with a doubt. i have some mpeg1 (352*204) movies that have better images than mpeg2(352*480), but i never did mpeg1 at 480*(ntsc)!

he can do in mpeg1 with this resolution :?: (i'm really uncertain) :?

Most players support it even though it's not standard compliant. He could try muxing and authoring the MPEG-1 file as SVCD which might help if the player doesn't like the clip. Works on my standalone.

great and good remember!(and right, i forgot that cos a long time don't use..only encoding kdvds now) and seems that lots of new player can play it. is one good option cos mpge1 give excellent quality and compression!

Agreed (I do all my KVCD like this and I wonder if I won't use it on KDVD also). And last tmpgenc release is even better on MPEG1 than previous one !

yes, i was thinking the same a few minutes! 8)
i need to test the new version, i don't knew that!

we have good hints here to get good results,was in our face.
:wink:

yes, i see that only now: Sample of new TMPGEnc 2.524.63.181

really deserve test to KDVDs with mpeg1! is my next target.
:)

Sorry but doesnt a Standalone insist on "pulldowned" mpeg2 Video Streams in ntsc mode?

sorry st. INClauss, i don't understood! :?
i'm thinking to do kdvds mpeg1 720*(ntsc) and i loose what you mean.
can you expalin better please about pulldown in this case?

If you are doing NTSC DVD, you are supposed to do them in 23.976 with 3:2 pulldown, in order to have the layer to see them in 29.970 (only legal fps allowed on NTSC disc).

But MPEG1 does not support pulldown, so you can't do NTSC DVD with this (except if you do 29.970 interlaced MPEG1). Inc is right.

I had a similar problem yesterday : MPEG1 does not support 16:9 flag ! So the DVD comes out in 4;3 and not in anamorphic :-(
(not really a problem if you can force the mode with your TV remote, like I do).

all right is clear!
as i do more musicals than "normal" movies and they are 29,97 interlaced then is ok! what about one 29,97 interlaced as mpeg1 and another in 23,976 mpeg2 with 3:2 pulldown in authoring program?(seems possible but i never did).....is possible? and with ac3 audio? i have more questions and ideas...depend of yours answers!

NO :-(
I did a mistake : MPEG1 does not suport interlacing ! :oops:

So that is not possible to do MPEG1 DVD in NTSC.

PAL is okay :-D

I'd give the Convert60i24p function a go, converting the interlaced 29.97fps stream into progressive 23.976fps. That is, if you want to use MPEG-1 on your truly interlaced NTSC sources. Otherwise, MPEG-2 is the only option.

right!
means that i can encode musicals in 29,97 mpeg1 (ntsc) and "normal" movies in pal-G :?: ...as i never did a pal encode i don't know how it will show in my pal-M tv that have different standard of palG.
i told you....more ideas .....and about ac3 and if i can author that mpe1 29,97 mpeg1 and "normal" movies in standard G together in some author program if all are mpeg1 encodes :?: :?

we posted at the same time Boulder!

Even if you converted it to PAL, it would still be interlaced, so it's a no-go.

ok....then this is the "solution"? or have any other way?

If you want to use MPEG-1, you'll have to do the 29.97->23.976 conversion. There's the sticky thread Kwag started which includes both the original (fast, good quality) function and the further developed one (slow, better quality).

ok thanks....!
i need to test it after restore my whole system (thunders damage 2 hdds here)......next week i will start and (maybe) more doubts will came!
please,...nobody answer me about AC3....is possible to use :?: (seems ok but i need to be right)

where is it please? (some days out of the forum and i loose some news)

ac3 with MPEG1 you mean ? Yes it's possible. Let remember that all this will be muxed in a vob. A vob can contains either DTS if you want !

News ? :lol:

if you don't mind Phil, :oops: let me ask for the right place where Boulder told about "sticky thread Kwag started which includes both the original (fast, good quality) function.."...i can't find that option for "fast,good quality"....please send me to the right place!
thanks to answer about ac3 with mpeg1, will be great use it :wink: and if you want delete this "too big" group of questions .....BR! (best regards)

The original Convert60ito24p function is here : http://www.kvcd.net/forum/viewtopic.php?t=8678 , in the first post by Kwag. It produces good quality and it's quite fast. However, I would use either KernelBob or TDeint's bobbing capability instead of a standard Bob() in the script.

I posted the further developed version in that thread later. It's much slower but produces better quality.

Converts 60fps Video into 24fps
cool thread (saved). thanks! :)

No I can't do MPEG1 with this resolution. I'm doing like Boulder and Dialhot said, muxing as SVCD.

I'm having problem with the prediction with the new CQMatic (1.3.10) and TMPGEnc (2.524), I'm getting a different CQ- value everytime I encode (no change of settings). Can someone confirm this or am I the only one having this problem?

I'm working on a new version of CQMatic.
Stick around ;)

-kwag

I will!

Until then I'll just continue testing and experimenting with the current version(s). 8O

Finally got the time to encode the movie. Final cq 67 with 128kbps audio and resolution at 480*576. The picture is of course a bit soft because of the settings used but well watchable.

The new version of CQMatic works like charm! It almost gave perfect fit, with a slight overburn I was able to put the movie on one 80min CD. :D
