I have a 75min movie, i'm using the guide from there http://members.lycos.co.uk/dcdvideo/...cqmatic_ad.htm step by step.

At the end, I always get a file arround the 900Mb, and this is only the M2V file. The sound is not multiplex yet.

My question is WHY?

CQMatic (1.1.01) give me a CQ78.98 after the #10 prediction.

My file to encode is MPEG2 704x480, 23,976fps with a average bitrate of 1318. The template I load at the beginning is the KVCDx3_MPEG2.

What i'm doing wrong?

Thanks

Hi Rambytes,

What are you using for MIN and MAX bitrates

The same form the website, under "long movie":

Min 300
Max 2000
Average from Movie Stacker is 1318

First, get 1.1.02, which is the latest. Then, make a quick prediction test.
Change your MAX to 2,500 instead of 2,000. I want to see if your CQ drops considerably

My source is directly from DVD2AVI, so is interlace, but I encode "de-interlace"...

Does I need to check the box "interlace" in this version?

If your source is a DVD, and it's a movie, then it's not interlaced
Unless you're encoding a "VIDEO" DVD (Musical, etc. )
If it's a movie, you use "Force FILM" in DVD2AVI, and encode at 23.976 "progressive". Not interlaced.

WTF???

I've enable the "force film" and my movie pass from 75min in MovieStacker to 95min???

And i've don't pay attention, but my movie is not 75min, but really 95min.... 1h30 approx, not 1h15....

That why my average bitrate is too high... i've pass from 1318 to 1028...

I will post anyway the CQ that CQMatic will give me after the prediction...

By the way, encode to 704x480 will be a GREAT resolution in my TV, or it's better to encode in 480x480?

See you in 1h approx... TMPGEnc is slow, even with a XP2600!!!

The Shorter (lengthwise) your movie, the HIGHER your "calculated" bitrate will be,
and the Longer your movie, the LOWER your "calculated" bitrate will be

Ok Kwag, after few setting, i've got a CQ66.84

And by file prediction, at 23%, the file is 137Mb, so at 100% the file will be arround 600Mb...

105Mb for the sound in MP2, and my 700Mb is reach!

Thanks Kwag, you're the best!!!

But like the "force film", what other setting I can enable/disable to get a better backup of my film?

KWAG!!!

You're right! My mistake....

After the encoding of the M2V file, I have enough space to put 2 audio track to my SVCD!!!

Thanks alot Kwag!

Hi KVCD community

i'm VERY new with all this stuff and just did my first steps into kvcd
and tried to backup a dvd.
(no... it was the 5th try, but now i've no idea, what's going wrong...)

like most other newbies (seems to...) i'm getting in trouble with
file size prediction. my file was getting too big.

so... here's my question to all you 'professionals',
hoping someone can help me!?

what have i missed?
(after reading guides and this forum since one week )
shouldn't the result be closer to the prediction?
what must be changed in my procedure?
any other procedures more 'safe'?

---------------------------------------------------------------------
what i did...

source: DVD
16:9 / Progressive / PAL
720 x 576 / 133 Min / 25 fps

---------------------------------------------------------------------
used programs:

DVDDecrypter 3.1.7.0
DVD2AVI 1.76
bbMPEG 1.24 (beta 1
Calcumatic 1.06
CQMAatic 1.202
Moviestacker 2.00
TMPEnc 2.512.52.161
AviSynth 2.5

---------------------------------------------------------------------
1.) Ripped with DVD Decrypter

Audio demuxed with d2d2avi
Result: AC3 T02 3_2ch 384Kbps DELAY 120ms.ac3
Saved as movie.dsv project

(btw: what does the delay time mean? is it important?)

---------------------------------------------------------------------
2.) bbMPEG 1.24

Reencoded the audiofile with bbMPEG 1.24 as mp2 (112 kbps)
(108.932 kb)

----------------------------------------------------------------------
3.) Opened d2v with Moviestacker

Resize & Video Stream:

Source:
720 x 576 / PAL / Anamorphic / ITU-R BT.601-4
133 Min / 25 fps

Destination:
352 x 576 (1/2 DVD)
Use GripFit / Blocks TV-Overscan: 2 Resize

Resulted:
Average kbps 697 / 15 GOP per frame / Scene Change detect

Audio Stream & Authoring:
112 kbps
bbMPEG Miltiplexing MPEG 1
80 min CD

----------------------------------------------------------------------
4.) AviSynth-Script

My AviSynth-Script (GripCrop from Moviestacker):

### For DVD and clean material ( for use ONLY with AviSynth 2.5x )
### Now with Linear Motion Adaptive Filtering ##
### Ver. October 24, 2003 @18:09 GMT ###

LoadPlugin("C:\Programme\AviSynth 2.5\Plugins\undot.dll")
#
####

## Defined Variables and Constants ##
#
MaxTreshold = 1.50
nf = 0 # Current frame.
#
####

## Main section and static filters ###
#
Mpeg2Source("D:\Movie\Movie.d2v")
#
undot()
Limiter()
asharp(2, 4)
GripCrop(352, 576, overscan=2)
GripSize(resizer="BicubicResize")
STMedianFilter(3, 3, 1, 1 )
MergeChroma(blur(MaxTreshold))
MergeLuma(blur(0.1))
#
#

## Linear Motion Adaptive Filtering ##
#
# ( Portions from AviSynth's manual ) - This will apply temporalsoften to
# very static scenes, and apply variable blur on moving scenes.
# We also assign a variable - and this is why a line break is inserted:

SwitchThreshold = (Width<=352) ? 4 : (Width<=480) ? 3 : 2
ScriptClip("nf = YDifferenceToNext()"+chr(13)+ "nf >= SwitchThreshold ? \
unfilter( -(fmin(round(nf)*2, 100)), -(fmin(round(nf)*2, 100)) ) : \
TemporalSoften( fmin( round(2/nf), 6), round(1/nf) , round(3/nf) , 1, 1) ")

#
#

GripBorders()
#LetterBox(0, 0, 16, 16)
# Depends on situation. Use MovieStacker!
Limiter()

#
#
## Functions ###

function fmin( int f1, int f2) {
return ( f1<f2 ) ? f1 : f2
}

----------------------------------------------------------------------
5.) TMPEnc 2.512

Opended avs-script with TMPEnc 2.512
Loaded KSVCD-352x576_PAL.mcf Template

Saved 'ES video only' (with 'source range' and 'cut editing' cleared) as text-project

(btw: what would be the best template for this situation?)

----------------------------------------------------------------------
6.) Calcumatic

Opened d2v-project file
Min: 133
Audio: 128 (safety-buffer, because 'real'audio-rate = 112 kbps)
1 Disc / 80 Min CD

Results:

>> Average 694,6
0,57 * Av. 395,9
Video Size: 691728
Audio-Size: 127472 (128 kbps)

----------------------------------------------------------------------
7.) CQMatic

Opened TMPEnc-Project-Textfile
Set to Prediction only / Override default CQ unchecked

Prediction Final CQ: 64.05 (Prediction cycle #5)
Video Size: 691728
Audio-Size: 127472 (with 128 kbps)

----------------------------------------------------------------------
8.) Back to TMPEnc 2.512

in 'video/rate control settings' set manually to:

CQ 64,05
Max bitrate: 2000
Min bitrate 396 (from Calcumatic 0,57*Av.395,9)

Enable pading checked
Streamtype MPEG 1
Motion search precision: high quality
Checked 'ES video only'

----------------------------------------------------------------------
Result:
Encoded Video Size: 727.445 (should be ~691.72

... something went wrong. please help me to get the right

compressor

p.s. goes to this thread because i don't want to open another: 'CQ please help'

You changed the "motion estimation search" precision between the CQmatic pahse and the real encoding ? Do not do that.

@Dialhot

to make shure, i didn't make THIS mistake:

I have set 'motion search prediction' to 'high quality(slow)' in TMPEnc,
saved it to a new script and let CQMatic do its work again.

CQMatic/CalcuMatic Results:
CQ 64.30
Video: 691.728
Audio: 127.472 (128 kbps)

the new encoded MPEG had 732.634 kb (without sound)

Any ideas guys? (shure you have )
At which point in the procedure the presets could have that much
effect on the encoding results?
Maybe some wrong presets TMPGEnc ?

thanx
compressor

Hi compressor, welcome

wow, that was a nearly complete info you've given
At first sight i can't see any errors.
Maybe your TMPGEnc text project file could help here
Do you have problems predicting other sources
Can you make a try with DVD2AVI 1.77x

I would say "bad luck compressor". I did a lot of KVCD yet with CQMAtic, and this we, I had my first "failure".

Catch me if you can, CQ predited with sound at 112kb/s... the final size was 50 Mb below the target, even when muxed with audio at 128 !

That's the first time CQMAtic ws so far from the target for me.
