Hi all, Greetings.

Am new to this forum and was waiting to get access.

I heard a lot about the progs Auto GK and Gordian Knot in Doom9 and much impressed and
relaxed. I have downloaded and was trying with the guides to convert my DVDs to a 700MB avi
as well. I had been using a lot of standalone oneclick tools for many years and was getting
data with low quality and undersized or oversized (too poor and need bit more access to the
editing field they provide).

I tried AGK but always getting output AVI file with very low bitrate even all my DVDs are
Master copy and in excellent quality. I had set all necessary field in hidden options too but
no way. Am trying to get a much improved quality, a predefined size and bitrate, totally with
an individual setup.

I tried GK but always get stuck at some field. I've seen
files are in excellent quality with a bitrate of merely 1000-1500, so why couldn't i do n
get the same with GK(am not a master and just following with GK guides and useful
suggestions & advices by many expert friends in doom9).

After creating project with r4r (.d2v and compressed subtitles)i usually go to GK for
settings and conversion of .avi. At first i do set the XviD as per the guide (1st&2nd Pass)
but see in 2nd pass am setting the Target Size & Bitrate manually with the Bitrate calc by
clicking on the right button and entering:

Target Size(Kbytes): 716800
Subtitles: 0
Format: Avi
Video: hrs, mins and Secs
Frames/sec: 23.976 film
Audio format: mp3 CBR/VBR 128

The result for final out put is:

Size: 594028
Bitrate: 634

Then i go to the next steps with GK as well but after opening the d2v proj file i could see
a bitrate of merely 600 to 700 in GK(right side-Size 700mb and bitrate 687) and not able to
edit that field. After selecting Audio and setting all other options including
cropping, resizing, resolution set etc the bitrate gradually reducing(around 646).After
conversion am getting a file with bitrate of 664 or 668,looking very poor quality too and
got wondered. I tried a lot with different settings but fed up and in well disappointed, why amn't
getting a good quality with decent bitrate like others do??:confused: I did a manual increase in
bitrate by putting in Xvid but file size became too oversized.

Probs facing there is:

1.I couldn't change the bitrate in GK and getting a lower bitrate when putting projects.

2.If i manually increase the bitrate in Xvid 2nd pass then file getting Oversized.

Request:

1.How to get an exact user defined bitrate and size(700mb) for the output file?


I have gone through almost all the guides explained and in confusion. All are saying that
they could do the same with GK well so am in a "?" what happened exactly in my case..

Hi friends, if any possibility with GK and if i should make any important changes in
anywhere then plz kindly suggest me a solution to do that or give me better advice in this
regard.
If you need anything else frm my side plz let me know the same.

Am spending all my free time with GK to achieve my goal for a long but still in a comma.


Thanks in advance...
Warm Regards..,
Ajay.

In order to have an adjustable output size within Gordian Knot, you need to set mode to "Calculate Average Bitrate."

You'll need to use a VfW build of Xvid in order to get properly-sized output files. Don't bother setting anything for file sizes in Xvid except Twopass, 1st and 2nd pass in their appropriate settings, the rest will be ignored.

Hi CWR03,
Thanx for ur advice..


In order to have an adjustable output size within Gordian Knot, you need to set mode to "Calculate Average Bitrate."

The same is automatically sets there hence i open a d2v proj file it shows the bitrate of around 700mb.If i do make the svi conversion with these rate then output would be looking very dirty know so wat to do?

You'll need to use a VfW build of Xvid in order to get properly-sized output files.

Currently am using the built in XviD with GK pack and i had tried updated the latest version too.Hi, whats that VFW Build version?

except Twopass, 1st and 2nd pass in their appropriate settings,

Hi i have set the 1st pass with recomended settings as per Xvid guide and in second pass i have set the size and bitrate as i described earlier in my first post. Is there any prob or need to make any change there??

My DVD has much more bitrate and quality,its a master copy.


Thanx again friend..

I don't know about the technical details here, but here are some of suggestions:

Firslty, Why are you sticking with 700 MB file size? I don't think you are using CD's. All stand alone DVD Players (that we connect to TV) can support Pen Drives these days. Even a 1 GB pen drive can store data upto 950 MB. So you can increase your file size to 950 MB.

Secondly, what is the duration of the movie you are converting to AVI? If you are going to convert 180 mins movie to 700 MB then the quality will definitely be low. Give me the length of your movie, then accordingly I can suggest something.

General suggestion: Encode Audio at 192 kbps VBR if it's action movie, 144 kbps VBR if its a normal movie. Let AutoGK choose the width automatically.

For normal movie of 90 mins, I think 800-850 MB will be fine. Then for every 30 mins increase in movie, add 125-150 MB of size.


Lastly, why are you not satisfied with a low bitrate? Are you watching on High Definition TV or High Screen size laptop? The size of the screen can also affect it.


I could not get into your details but these are general purpose suggestions that can help achieve the desired results.

Hi axxo,

Thanx for ur suggestions.

Why are you sticking with 700 MB file size?

Yes, i want to make a movie from 4.7gb dvd to 700mb avi as i have seen the same a lot with good quality thats wy.. For me, its not a prob to keep the dvd as well but my need is to build a 700mb movie like others do.

what is the duration of the movie

Its a 125mins movie. I got a lot of xvid .avi movies that all merely 2 or 2.5 hrs with extreme quality and at a bitrate of 1000 to 1300 So, it is possible to make movies like that know.

Yes, i had tested with AGK and tried almost all the options n settings in different way but always getting an output with correct size but low clarity(580 to 680 bitrate).

Lastly, why are you not satisfied with a low bitrate?

I have noticed that most of the movies encoded to .avi having a definite size around 700mb and a bitrate of 1000 to 1300 so its looking fine and best quality to watch thats why am trying this with GK.
See, am not watching any HD or HS Lps i said know its for my personal use like some others. I did some conversions with the attributes that automatically generated by GK(a bitrate of 630) but the size cameout almost ok but quality as very low with the same rate.

When i open the .d2v to GK itself its showing the same (680)bitrate and couldn't able to change it for 700mb file,only option is to select a double size.

Plz update me if u get anything fishy with the info i provided.

Thanks again friend..

Closing this thread for presumed rule 6 violation. Please clarify in PM if you want your thread re-opened.

You cannot discuss "scene rips" and how to duplicate their results.
