KVCD: Resolutions, Resolutions, Resolutions!
 

Just reading through the forum I come across all different sorts of resolutions to use when encoding KVCD's it is a little bit confusing try to follow all the sizes here, i was wondering if there is a page or chart that shows resolutions and what to expect with what templates and sums it all up?

Thanks :oops:

Hi TLTw

Have you checked this site?

Thanks for the link Totonho03 :)

That's actually not a very good chart in my eyes...

Standard VCD resolution would be: 352x240(288)
CVD (1/2 DVD) resolution would be : 352x480(576)
SVCD resolution would be: 480x480(576)
KVCDx3 (3/4 DVD small) resolution is : 528x480(576)
KVCDx3 (3/4 DVD full) resolution is : 544x480(576)
XVCD resolution is : 704x480(576)
DVD resolution is : 720x480(576)

and that are all resolutions that you could in a way refer to as standard, although the only real standards here are VCD resolution and DVD res...
However XVCD resolution should work on most players too, since it's the standard Still Picture resolution.

Thanks Jellygoose,

I also had similar thoughts about that guide after i read it, giving only the standard sizes for each format.

Well as I said... Most of these are still non-Standard, although used by lots of people here :wink:

I have a question:
What resolution should I use if I'm encoding 2 hours movie? (actually I'm now encoding 110 min) I've never tried any other resolution than 352x240(288).

You can have very good result also with 352*480(576). Above this, I personaly prefer CD90 min for a 2h movie (and then I use SVCD res).

I haven`t found many movies two hours and under, that won`t fit on
an 80min cd at 352x480 rez...as long as they`re in widescreen "Film" mode.
(using current "MA" script)

Of course visual quality is always subjective. (in the eye of the beholder)

The Devil`s always.....in the Details!

Unfortunately I think I've tried all possible resolutions but my dvd-player plays only 352x240(288).
The good thing is that the encoding process with this resolution is much faster:)

Edlung,

Have you tried encoding in MPEG2?

No:) Is this the reason?

hi Edlund,

Not necessarily. But, mostly likely, you DVD player has issues w/ some
encodes (aka "x" format) and that you DVD player is "fixed" at the so called
"standard" formats ie, VCD for MPEG-1, and will only play w/out issues in
this format :!:

What "vmesquita" was advising, was that maybe your DVD player is just
too picky with non-standards, and refuse to play properly, and that maybe if
you try some various encodes in MPEG-2 format, (even "x" formats) you'll
probably have a better chance.

In other words, give SVCD, xSVCD, or is it KSVCD etc a shot at it, as you
might have a better experience, as these are MPEG-2 variants :)

-vhelp

Ok, thanks, I'll make a KSVCD and see what's the difference. But as far as I know the MPEG2 is bigger and I wonder if it's possible to use it for encoding movies that are longer than 90 minutes?

I still don't understand this resolution thing
 

OK, what I don't understand is this. Each KVCD template is automatically set to a certain resolution, right? Then why does the TMPEnc project wizard force you to pick a resolution again on the next to last screen of the wizard? Should I always choose the resolution of the template I'm using, or no? HELP!?!?!

Hi Cougar_Pines,

Never use the wizard :!:
Select your templates manually.

Well, if I load the template with 528x480 and my player only play the SVCD 480x480 res, can I load the unlock file either and change only the resolution to 480x480, it will work?

Yes! But remember to change to MPEG2 if needed.

Yes you can, and Yes it will work ;-)

@Cougar_Pines

The resolution thing is not based only upon the lenght of a movie. It also depends upon the contentsof the scenes.
The best way is to define a resolution, do a prediction and your decision should be refered on the CQ Value which will be calculated by using CQMatic or TOK.

Example: The Thriller "Seven" ... much dark Scenes and minimal flashing or fast moving scenes ...
Using TOK or CQ Matic gave me a CQ about 80 using 480x576 (in my case PAL) fitting on a single CDr80 with 128kbit Audio (wow ... something wrong?? no ;-) ). So you also can set the resolution to 704x576 and you still will receive a very good CQ and even better quality. In may case (my player does not accept 704 movies if not authored and burned as a DVD) I decided to add an extra language audio track. I predictioned again now including 2 audiotracks each 128kbit and the result was 72CQ @ 480x576. Perfect.

Well this movie is an extreme example.

On the other hand "Mesage in a bottle" ... 480x576 128kbit 1CH audio gives me 47CQ (1CDr80) .. dammn ... even when using the MA script .. extra Convolution3D rises the CQ to 49 and so I decided to encode this movie to two CDr80 cause I prefer better quality on 2 disks than 352x288 on a single one. 352x576 in my case (player model) is also only accepted on a DVD.

So do your prediction before an decide when looking at the CQ Value.
This gives you the option to do what ever you want ... bigger/smaller size, upper/lower audiobitrate or even a second audio track if you got a very good CQ.
