Can I add subtitles when I encode from DivX to SKVCD? And from the letter you seems to have forgot

I'm veery new to kvcd and havent done anything with that thing CQ value. So you mean,if I high the CQ value I will get better quality? Well then, how do i high the CQ value,cause I want better quality Should I be ashamed to ask this

And how much should I high the CQ value to

And this one

And btw ... I load my DivX file into Vdub, then File>File imformation.
Then it shows me the avi imformation. If this part look like this:

Frame size, fps 640x272, 23.976 fps

Should I use the SKVCD NTSCFilm 352x480 tample instead of the SKVCD PAL 352x576 tample?

Think so couse this, 23.976 fps, shows me that it is NTSC,am I right?
And does SKVCD NTSCFilm 352x480 tample give me the same quality as the SKVCD PAL 352x576 tample?

Aaand I have one last question...Is 640x304 resolution better then 640x272?

Many questions hope you can answer them all :P

Yes. But they are permanent subtitles, meaning you encode them in your mpeg file. You can't switch them off once you encode them. The higher the CQ, the higher the quality, but also the file size. You use file prediction to find your CQ for either one or two CD target 23.976 is an NTSC FILM frame rate, so you have to use NTSC templates. 23.976fps and 29.97fps are NTSC. 25fps is PAL. Slightly better

yep, the higher the CQ the better the quality.

in TMPGEnc the initial screen has a button Setting...it's on the bottom, third from the right- click that- a seperate window will show..MPEG Setting- under the first tab Video- under Video stream setting you'll see Rate control mode:- to the far right of that hit the Setting button..another window will open titled Constant quality (CQ)- the first slider from the top is Quality- you can also enter values with decimals by positioning mouse arrow over the window and right-click.

hope this helps

If it's SKVCD, mpeg-2. muxed as SVCD, then you can use switchable subtitles.

Use SBTMaestro to render a set of bitmaps from the text file with subtitles you have.

Then mux the the subs as in the guide (see first page for the link).

oke , thanks guys But can I use the way rendalunit said to high the CQ value instead of the File prediction. That thing with File Prediction seems to me much harder Or is it? If it's muuch better to use the File Prediction were from should I download it

That thing with the subtitles...If I've got it right you mean that I can turn the subs ON and OFF on my DVD player...

One thing more...Higher resolution, better quality

You _must_ use prediction, otherwise you'll end up with a 1GB file or a way too small file. See the File size prediction forum or Black Prince's guide in this forum. It's not hard to do after you've learned it - and that's what this all is about: learning

You can view the subs if your DVD player supports them (not many do, unfortunately). There's a DVD player list at vcdhelp.com, see what that list says about your player.

High resolution doesn't necessarily mean better quality. It depends on the source material etc.

Thanks Boulder Buut I downloaded the File Prediction from http://www.jungleweb.net/~sansgrip/K...dictor-0.2.zip , found it in the Divx to kvcd guide. But when I tried to open the program it just gave me an error

WHY!!??

//Wolfi

You have to install the .NET framework. KVCDPredictor runs only on .NET platform. Go to Microsoft's site and download it.

This file prediction makes me confused

Preper yourself for more questions in the near future

hey wolfi,

I really don't want to be impolite to anybody, but maybe you should start learning by reading, and after that a little learning by doing. Nobody here that I've seen so far has ever been impolite or rude to anyone, me included. (well haven't had any complains yet )
But it's just more fun to learn things by yourself, just like it's more fun for the more experienced users to concentrate on questions that haven't been asked yet! I'm sure that you'll find a lot of answers and help by just searching through the forums!

Don't get me wrong buddy, everybody is welcome to ask at KVCD, and I'm sure I speak for everybody here right kwag?

Have fun buddy!!

Btw: About the file prediction: It's a method to calculate the file size that your movie will have after encoding using CQ mode. It calculates the CQ value for you, so that you don't have to guess... You might want to check out the "Manual File Prediction" in the File Prediction Thread!

I'm trying with that part Black Prince made and the mini how to Kwag made Hope it will work out

Yes. IF... your player can show the subs as CVD or SVCD.

I've crossed a problem. I'm following Kwags mini how to manual, and...

I want the movie to fit on 2 cd's. But the manual only shows how to make a movie on one cd. Should I do exactly how the guide shows me or should I change something, like cut my audio file (159mb) into 2 pices? Or should I do this: 2*800(cd-r)=1600mb and then--> 1600-159=1441 have 1441 left for my video stream.

Hope you will understand this PLz, I'm quite stuck right now...

//Wolfi

Exactly

-kwag

Good I'm right on that part but can you tell me if I'm doing anything wrong here...:

Total frames: 145300
Test file size: 12.31
Audio file size: 159 mb
Movie time (minutes) 97min

2*800=1600mb
1600mb-159mb=1441mb (have 1441 left for my video stream)

145300/97/24=62.414

1441/62.41=23.09mb

Now I took away "#" from #Sampler() and encoded the avs. file, who came out as 12.318mb. I suppose this is the Test file size

When I checked the CQ value in TMPGEnc it was set on 60CQ.

23.08/12.31*60=112.4939

The highest CQ value is 100! How can I have it to 112.4939 What have I done so badly WRONG?

And this part of the manual:

"It usually takes 3 to 4 samples to hit your target this way." What si my target , as i told you before,I'm slooow...

//Wolfi

So that means that probably even at a CQ of 100, you still won't reach your wanted sample size . What is the sample size with a CQ of 100 If it's below your wanted 23.09mb, just leave at 100 and encode your movie

-kwag

Just raise the CQ value, try 80 and see if it comes closer. If it produces a too big sample file, try 70. If that's too small, go for 75 and so on..eventually you'll hit the spot.

Aaahha so I should high my CQ, as Boulder said, and hit my target 23.09mb So the test file should come out as 23.09mb am I right? So now when it's written I should high my CQ to 112.4939,but cant, I just have to high it to 100CQ , cause that will give me the highest quality possible. Am I right?

oke I'm close to understand this now... but this thing,formel or whatever it is:

Here's a sample spreadsheet with these formulas:

Quote:
Sample File Prediction Spreadsheet

…………………......A..........................B……………………… …………
..1..Inputs…………………………………………………………………
..2……………………………………………………………………………….
..3 No. of CD’s.............................1…………………………………….
..4..Audio File Size.......................99,000,000…………………………
..5..Totals Frames........................152,255…………………………….
..6..Test Frames...........................2,544………………………………
..7..Movie Length (seconds).........6350…………………………….…
..8..Test File Size..........................24,053,987…………………………
..9..Current CQ_VBR....................100…………………………………
.10…………………………………………………………………………………
.11..Results……………………………………………………………………….
.12………………………………………………………………………………...
.13..CD.File.Size............................=813, 019,155 * B3………………...
.14..Factor.....................................=@ Round(( B5 / ( B7 / 60 ) / 24,2)
.15..Target File Size.......................=@Round((( B13 – B4 ) / B5 ) * B6,2)
.16..New CQ_VBR..............................=@Round(( B15 / B8 ) * B9,2)……..
.17..Diff %.....................................=@Round(( B15 – B8 ) / B15,2)…….
.18..Corrected CQ..........................=@Round(( B9 + B16 ) / 2,2)……….

Enter data in Inputs. Results will give you the calculations. Use Corrected
CQ for your next test. If Diff % is ~3% or less, you have come close to your
Target File Size. If Corrected CQ is greater than 100, than use 100 the limit of
Tmpgenc. Row 17 Diff % is format percentage, 2 decimal places. The other
rows are format numeric with 2 decimal places.

I dont understand this, even how much I try, can get it.
Should I add something to my script or what

The point is to alter the CQ value until your sample size hits that calculated target, 23.09MB.

I suggested setting CQ to 80 as the scale is not linear. Set the CQ value to 80 and encode the sample strip. If it's too big, lower the CQ value. If it's too small, raise the CQ value. It's really simple, you just can't calculate the correct CQ value (due to the non-linear scaling), you'll have to estimate it and then encode a sample strip and see if the size hits the target.

There are often spikes in the scale, I've had many movies where the sample file size has barely changed with CQ 70-79 and with 80 it's suddenly several megabytes larger!

sample strip= the test file who should hit 23.09
