Convert 3ivx movie to kvcd format?
 
what's the best way to convert a 3ivx xl .mov file to a kvcd?

Dialhot 02-18-2004 04:45 AM

Using directshowsource insteed of mpeg2source or avisource perhaps. But I never had one to test.

... sorry, i don't understand. it's a dvd-rip straight to .mov format. when i use tmpgenc, it takes like 7 hours and the quality is worse than if i had used an .avi -- however the quality of this .mov file is soooo good. it is 1.6GB and i'm having to use a CQ of like 43 just to get it under 800MB. the movie is just under 2 hours. the .mov res is 855x352 and i'm converting to 768/672x352 res, as 352x240 makes the picture very smushed looking. min and max bitrate was 300 and 1800. i lowered the max to 1000 thinking that may help.

i really just don't know what i'm supposed to do with a file like this. the quality is so much better than any .avi i've seen, so i would like to find an effecient way of converting them to kvcd so i can stick with them.
thx for helping

That was already discussed here so I just point to the Thread ;-)

that doesn't help, it's not an avi2mov file. i just want to know if there is anything i can do other than have the qtreader and throw the whole .mov in tmpgenc.

incredible 02-18-2004 04:50 PM

It works best if its NOT an avi2mov file as this means to the reader that he deals with an orig mov file.

TmpgEnc only supports movs directly via the quicktime reader plugin, thats the fact.

Icebound 02-18-2004 11:29 PM

i don't deal with avi2mov files, just straight dvd2mov 3ivx xl -- what's confusing me is that i can't get the converted file to look better than an avi converted to kvcd. the 3ivx xl .mov files are 100x better than any dvd2avi file i've seen. why do i have to use a CQ of 43 for a 1.6GB .mov just under 2 hours to fit a cd? for the same movie length in avi, i use close to 80. thx for replying

That's because you're trying to convert an already converted movie :!:
Try a direct DVD->KVCD conversion, and you'll see the difference.

Icebound,

tell me the exact workout who do you converted from DVD to 3vix.mov! As you should have done the conversion by yourself on you original.

So I assume you did use Quicktime for that, right?

What do you mean by "it doesn't look that good like when Im doing a AVI to KVCD conversion"??? Blocky blurred colors, unsharp, blocks in motion parts or blocks in dark parts?

Icebound 02-19-2004 12:24 PM

like i said, i had to use a CQ of 43 to get it to fit on one cd. that's how it looks worse than an avi where i usually use around 80.

i didn't convert it, it was done with quicktime -- i know the guy that's doing it, he goes by appleguru -- but i was trying to avoid all that.

anyway, an avi is a converted file so how is that cool but not converting from mov? the quality of these 1.6GB mov's is insane!!! i'm sick of avi's now. soooo, i just wanna convert the mov's to kvcd!

i was just wondering if anyone knew of an effecient way of converting mov to kvcd. ... and y'all don't -- so thanx for ur time.

Dialhot 02-19-2004 12:48 PM

There is no reason the CQ is 43 just because of the orignal codec.
As I alwas say, TMPGENC receives uncompressed picture from avisynth and doesn't give a shit about how it was compressed before.

You would have the same problem if your source was an AVI. It's just that this source does not compress very well (full screen movie perharps ?).

Or the 3ivx codec normalize the luma (that have a terrific impact on CQ !) and you can try to use ColorYUV for shrinking it a little (see avisynth doc, it's an internal command of avisynth).

EDIT : Can you show me your script ??? What is this resolution you use ? And HOW !

the .mov res is 855x352 and i'm converting to 768/672x352 res
What the hell is that res :?:

Edit 2: YOU LOWERED MAX TO 1000 ????
How do you want to have something good with that ? :-(

incredible 02-19-2004 02:03 PM

Icebound, I work on Apple too and I switched to PC according to mpeg stuff and I can very well say that XXX x 352 of your apple "guru" friend is a very worse decision to encode cause of half vertical size and we all know that the very big advantage according to sharpeness is based on VERTICAL resolution. Theres only ONE advantage, to get rid of interlacing if the source was interlaced, but that means just discarding fields = bad idea.
If you want to encode 1/2 size then we choose half width! Means 352x576.

So if you say that you're sick of avis, I don't know if you have seen well done avi encodings till now. (no offense my friend!)
Because I cant assume that that 3vix at that resolution gives such a perfect picture at 4:3 if watched on Tv and thats our purpose.

BTW: 3vix is an old codec and I don't know exactly if it has been further developed since the last 2 years? Im have been doing much encodings using FFmpegX and Ive never used that codec in case of apple mpeg4 encodings.

Icebound 02-19-2004 04:27 PM

i haven't been using avisynth or anything, just tmpgenc. i'm not sick of avi's -- they're very easy to work with -- it's just that the quality of these 855x352 .mov's is greater than any avi i've seen. they are almost always around 1.6GB for 2 hours. ... so i should leave the max bitrate at 1800, but what else? what resolution would you suggest? at 672/352 the picture is very smushed looking. i was just hoping that i could convert these .mov files to kvcd with a better result than avi files. thx

BUT WHAT THE HELL ARE THESE RES ???

Valid res are 352*240 / 352*480 / 480*480 / 544*480. PERIOD !

WHere dis you find these crappy XXX*352 values :?:

Note: at 1.6Gb for a 2h movie it's easy to make something awesome with divx codec also :!:

Icebound 02-19-2004 04:48 PM

i didn't know u could only use those res's. i was just trying to keep the res as close to the original since it was very smushed looking at 352x240 but it was kinda smushed at 672x352. so which res of those four would u suggest using?

You are taking a level 2 lesson with KVCD without having the slightest idea of basics of VCD ? For sure you like difficulty ;-)

Go give a look to http://www.dvdrhelp.com/, see a little what VCD, SVCD and XVCD are, that will be really precious to you.

In these case, better use the original res, no ? Why make you choose 672*352 ? I still didn't understand that. Arbitrary values taken from nowhere ? I don't think so. So... what ?

For a 2h movie on a CD80 with good result ? 480*480 (or 480*576 if you are in PAL area) and a max bitrate to 2200.

Icebound 02-19-2004 05:38 PM

tmpgenc says the original res is "illegal" so that's why i changed it. i've been making kvcd's for a good while. i used acp mostly, but started getting serious problems from it. now i just us vdub, besweet, and tmpgenc -- that's it. i know it's not enough, but moviestacker just puzzles the hell out of me no matter how many times i try. won't increasing the max bitrate make the file larger? thx for all the help

Dialhot 02-19-2004 06:00 PM

When Tmpgenc says a res is illegal that only means taht is does not understand the stream that you provides to it. As it does not understand, it can read the header, and so can't find the resolution you want (because this information is in the header). So it gives the message "illegal resolution" but in fact you have to understand that as "I can't say if your resolution is correct or not as I can't even read it !".

Moviestacker has nothing such complicate; A lot of things in it are useless (as the filters for instance as they work only for avs2.0x and we use 2.5x). The only interesting part is the resizing parameters. And you should take a little break, sit down, have a big breath and try to understand such essential things as resolutinon and bitrates ! Then you can resume your travel on the wonderfull path of video encoding !

Because then you will know that it is not he max that increase the filesize but the avererage ! And you will avoid doing nasty things.

1000 is under max of VCD (1150) ! So with that you can't obtain nothing else than a bad VCD.

Did you ever try to drive a car without having learn the main road signs ?
