script for anamorphic kdvd
 

is this script okay for doing an anamorphic kdvd ???


AviSource("c:\hum.avi",false)
BlindPP(cpu=4)
Blockbuster(method="noise",detail_min=1,detail_max =3,variance=0.1,seed=1)
Convolution3D(1, 6, 12, 6, 8, 2.8, 0)
GripCrop(720, 576, overscan=1, dest_anamorphic = true)
GripSize(resizer="LanczosResize")
Undot()
TemporalSoften(2,7,7,3,2)
DCTFilter(1,1,1,1,1,1,0.5,0)
#Blockbuster(method="noise",detail_min=1,detail_ma x=10,variance=0.3,seed=5623)
GripBorders()
TextSub("c:\hum.srt")

You are doing an avi. I wanted to suggest you to NOT turn it into KDVD, but I decide to keep cool on this.
But now... you want to make it anamorphic ????

You are really relax on the quality of your jobs :-(

BTW, as your source is not anamohpic but your target is, you must use this :
Don't be suprised if you can't raise your CQ above 50 !

(note : I put 704 insteed of 720. Same quality and still a valid resolution for a DVD).

Whats the advantege if the source isn't anamorph?!?!?

Even if Gripfit could do a nonanamorph to anamorph conversion, this would end up in a extremly "stupid" upsized height by the resizer.

The advantage of anamorph sources is that at there are as most as possible movie-pixeldata in the height which will be maintained.

to me the advantage of doing a non anamorphic source into anamorphic:

if the pictures anamorphic, i can zoom in with my widescreen tv so that i get a full picture ( even if it is slightly stretched),

if it is not anamorphic my tv will let me zoom in so much giving me small borders but retaining the aspect ratio,

but now im not too sure, maybe il just keep the aspect ratio correct and not anamorphic

the kvcds iv been doing have been coming out excellent quality and theyv all been xvids, so i figured to do kdvd, itl give me a better picture and i get to fit in two films on to the same disk, iv been happy with doing xvid conversions so far, maybe in the near future il start doing dvd conversions

Wrong.
One basis of the video encoding is to never enlarge a picture. When you enlarge, you magnify also the defaults. And divx have A LOT OF DEFAULTS !

A divx or xvid movie (in one CD, that is 700 MB) is barely watchable on a 19" PC monitor. I use to test a Divx standalone on my 35" TV set and I thought my heart was stopping.

As it is used on the net, this codec is not designed to be used outside a PC. Period.

Long time before you came to the board, we had a discussion about banish all discussion related to avi->kvcd conversion. Why ? Because the results obtained are awfull compared to DVD->KVCD convertion and all newbies that are coming to KVCD to make crappy warez movie DL on emule or whatsoever started to claim "KVCD IS SHIT" everywhere.

We finally created a special section for this and I did my maximum to provide a script that can give something acceptable from this goddamn codec.

Please do not ruin all my (our) efforts by using this to make KDVD :!:

Note: I remind you that you are supposed to do not copyrighted material or owned DVD only or all your post will be deleted. Just a reminder...

i was one of them people that was saying kvcd was shit,

the reason for this is beacuse i first heard of kvcd from digital-update, and i was shocked at the films they were uploading, the quality was SHIT, why people would bother making them if they were that bad?
to this day i have not seen a single good quality kvcd come out of them,
they all use really low res like 370 x 240, and the end results are bad, not one person has bothered encoding with higher res, and showed what kvcd can do

hence when i came here and worked out all the stuff i have been in ora of kvcd

all the xvid conversions iv been doing have been excellent quality, thanks to the scripts and stuff ( i personally avoid divx when i see it), i dont know why u dont like it dialhot??? iv been watching them on a big widescreen tv, and have little to complain about, but i can understand the difference in quality if ur source is dvd and not xvid

again sorry for saying that kvcd was shit, i didnt know better at the time

as for not making a kdvd, im just trying it out, if the results arnt as good as my kvcds have been i wont bother making them anymore

As soon as you are aware this kind of things cross widely the limits of the format and won't claim about the quality of the process, that's okay.
For sure test and tries are good things ! That's how we find new toys for playing :-)

Note: I used to be part of the quality evaluating team for MPEG2 when it was in the labs 10years ago and a piece of my engineer diploma is about digital picture processing. That is surely why I found Divx (as used actually for making 700 MB movie, I repeat !) bad and you don't ;-)

Interesting discussion. I've been making divx/xvid --> kdvd conversions ever since this forum started so I could watch my files on a 53" widescreen TV. Obviously the result is not as good as if I had a dvd source but I've been extremely happy with the results so far, especially with the various scripts you've provided Dialhot.

I'd be interested however in knowing what tips you have on making these files as viewable as possible. Here are my questions:

1) Should I always downsize my target resolution, e.g. use 544x480 or 480x480? 704x480 would always be upsizing

2) Is it better to encode in non-anamorphic and use the zoom feature of your DVD player or TV when watching on a widescreen TV?

3) Is it better to make kvcds than kdvds if your source is divx/xvid?

Any other pointers you have are greatly appreciated! Thanks

It depends on the quality of the mpeg4 and the resolution of the mpeg4.

I did some Xvid/Divx encodings to KDVD like at 352x576, but I agree with Phil that its not the purpose in regular to enlarge, maybe you can compensate by sharpen a bit BUT this is contra-productive to the right developed state of Phils "optimal Avi-Scripts"

Except if the zoom of your TV is really bad, you should use it everytime. Why ? Because when encode in anamorphic, your CQ will be down by almost 10 points. And the video will have big defaults.
When you encode in regular mode, the CQ is far better, and so is the video. Your TV zoom a good video, and the result stay good :-)

You can do KDVD at lower resolution than normal one if your player supports them. See my "KDVD Samples for standalone compatibility test" to check that point :-)

I actually can do KDVD with whatever resolution and whatever GOP structure. My two standalones read them all. If I do a 544*576 target for instance, a KDVD is better because I do the encode at highter bitrate than it would have been in KVCD.
But I will never do any KDVD in 704*576 with regular DVD GOP length (ie 15 picture insteed of 25) starting from a divx/xvid !

Thanks for the tips Dialhot. My TV actually does have a bad zoom but I just discovered that my new Panasonic DVD player automatically zooms 4:3 discs to fit a 16:9 television. The player also accepts any resolutions, such as 544x480 so that's what I've been making most of my encodes. My only concern is if my source resolution is closer to 704x480 than 544x480. Won't I lose a lot of sharpness if I downsize? In this case is it okay to upsize?

BTW, I use CCE for all my KDVD encodes and have never fooled around with the GOP stuff... but I am using the templates from vmesquita so I think they are already KDVD optimized. Is that okay, or should I change things if my source is divx/xvid? If so could you tell me what to change please?

Thanks again!

Be carreful : it can accept that on a VCD or SVCD but not on a DVD.

XVCD format, that is an extension to regular VCD, allow usage of whatever resolution you want. That is why a lot of standalone accept 544*480 VCD. But there is no "XDVD" protocol :-).

From a divx ? No. Never !

Yes they are. And you can increase the GOP length with them : it is already at its maximum size.

Are you sure about that? I encode at that resolution with CCE all the time to make KDVDs and DVD-lab will author & burn them no problem. The only warning I get is "This is a SATV frame size used for DVD. Not all DVD players will play it."

Yes sir.

You see : the warning tells you exactly the same I did :-)

Oh well I thought you meant it's not possible to make a DVD with 544x480 resolution, but from my experience you CAN. The only thing is it's non-compliant so it may not play on all players. Anyway it's a much better choice given divx/xvid source than encoding in 480x480 IMHO
