I'm no longer going to edit the first message on this thread... it's becoming a copy of my site, so better to go to my site :D.


The original post here was something like:

I've written this tool... here is the v1.00

I downloaded your utility, it's pretty cool, but can you please introduce a batch processing mode or something like a job list, this is very important.
And then an option to shutdown windows when encoding is finished.

Thank you...

[SuperflyTNT]

nice proggY, I'll use it when i use divx 5 ;)

[jonny]

@bobotns:
nice input ;)

@SuperflyTNT:
thanks :D

[ChAoS Overlord]

what is the "overwrite/delete" options necessary for? Doesn't this happen automatically?
Also does your utility switch to fast recompress or full processing? I prefer fast recompress most of the time.

Also why did you change: keyframe interval to 250 & max quantiser setting to 12?

[DJ Bobo]

@ chaos
The delete option is the contrary of the protect option in the codec, so it's usefull!
It works in fast recompress mode.
And jonny hasn't changed anything, you change the settings as you want, if you wanna 250 or 1000 for keyframe, it's your decision. Same for quantizers!

[ChAoS Overlord]

Hmm so am I right when I see, that protect is on when the delete option hasn't been activated then?

YES

[ookzDVD]

I think this is Divx4pass2 ;) win GUI.

Nice proggie,
next version should be batch support and shutdown after finish. :)

[rui]

Good work jonny
It even has an ending report, saying our average quantizer. :)

[yosemite]

thanks for such a prog , very helpful indeed :D

but I've a little problem:

I encoded Matrix and in Gknot I've choosen a filesize for 3CDs!
But the movie is smaller than 1GB, whats wrong here?

[jonny]

If you check overwrite/delete, the file will be overwritten (if exists) and deleted at the end of the encode.

If you don't check overwrite/delete, the file will be not overwritten (if exists, this generate and error) and not deleted at the end of the encode.

I dunno if i'll keep this options in the next ver... i think are not so useful... let me knot what you think...


@ookzDVD: hihihi :D

@yosemite: there are A LOT of answers in the forum for those getting undersized :rolleyes:

[DJ Bobo]

@ yosemite
I thought you asked such a question before. First: 3 CDs is a joke! don't go for more than 2 CDs for any rip! second: Matrix is good compressible, so it's already saturated by 1GB, so go for higher resolution like 640x272 or 704x304.
This has nothing to do with his utility!

You're right, it should be overwritten/deleted by default (also make your program "remember" all settings please)

[ulfschack]

Good job, jonny

Could you make the settings stick? Like in some sort of ini-file, I wonder?

cheers

[jonny]

Wait for the next version and keep posting your opinions ;)

sure, but not if u go for 2 audio streams!

[UHT]

it depends on the format of the audio streams i guess, 2 ac3 streams then maybe 3cd's its still overkill for such a short and dark film

[yosemite]

well, but a video-bitrate about 709kbps are not so nice in my opnion (thats what u get with 2 CDs)

think about it:
the 2 audio streams are about 2x 359MB!

[Acaila]

Still, 3 CD's is overkill. For a codec with B-frames it is even more so. And are you really going to listen to all those extra soundtracks?

And the bitrate doesn't say anything about the resulting quality. It's the compressability of the movie that determines the quality. High compressability with low bitrate could sometimes look better than low compressability with high bitrate :)

P.s.
With any dark movie you'll get ugly marcoblock artifacts in the near-black areas. But not even extreme high bitrate will get rid of those, so it's not worth the effort.

[UHT]

*UHT agrees 100%*

@jonny
What compiler did you use to make this file? Also (if you know) where can I get it?

Thanks,
TelemachusMH

[jonny]

@TelemachusMH:

The compiler is Perl 2 EXE
Link:
http://www.indigostar.com/perl2exe.htm

It's not free (there is a trial version)
I've emailed at indigorstar to know if i can publish a free util with the trial version... they offered me a free license :):):), very COOL

[jonny]

v1.01 Work with DivX 5.0.1 - DivX 5.0.1 + VirtualDub 1.4.10 -
- Option to disable fast recompress
- PE settings
- Scene change threshold setting
- The log files are overwitten by default and optionally deleted
- Save setting stuffs
- A lot of internal changes... job list in the next week ( i hope :D )

[Dali Lama]

Angelfire shut down your file d/l. Just want to let you know.

Dali

[TelemachusMH]

no they didn't ... you have to copy and paste the link into your browser.
(I just redownloaded it to make sure)

[Dali Lama]

Thanks, that worked. Sorry ;)

[muralin]

i did a copy & paste of the link on the browser and it said that the URL is no good. luv to get hold of the latest version.

[jonny]

I hope the moderator approve the attachment shortly ;)

[ShinerSpoon]

This is very slick. Thank you very much for taking the time to do it! Q: For the novice, were the default values you provided considered to be "about right" or would/where you suggest changes?

[jonny]

I stay with the default settings (i only change max quant depending of the comp. test value)
I don't use GMC and QPel because my compy is too slow to play the final avi :(

Play with the settings to know what are the best for you ;)

[jonny]

v1.02 Job list version! - DivX 5.0.1 + VirtualDub 1.4.10 -

(set the desktop at 1024x768 minimum...)


Homepage: http://jonny.leffe.dnsalias.com/

[ShinerSpoon]

I used this last night to do about 20 short test segments. Worked well. Thanks for the new feature, it's great.

[Frisco]

@ Jonny

Angelfire shut down your file d/l.


I like your tool and it is useful too me (v1.01).

I can get v1.02.

[jonny]

Now i'm at work (no access to divx5enc... angelfire shut down my ftp access too!!!)... when i'll go at home (2 hours from now) i'll send the 1.02 via attachment...

Can someone tell me a free hosting server better than angelfire to move all my work?

[jonny]

v1.02 Here

(Please wait until the moderator approve the attachment)

@edit: sorry.. had to remove the attachment.. all the people leeching a 1mb file plus all the people coming here for the xvid 2 pass tool is just above our bandwith limit. I'm upping the prog to my site now.

Sorry for this, i'll never expected this number of downloads.
I hope to not reach the limit in the freewebz site... (angelfire hosting was always down in this 2 days)

[kilg0r3]

I apologize in advance. For i am rather sure to ask a stupid question. But i can't help it.

What does this tool do that virtual dub's job control cannot?

Ps: Download worked via Internet Explorer but not via Opera

[jonny]

Nothing.
But with this tool is EASY and FAST to setup a lot of DivX 5 jobs (and to control the DivX 5 settings for every job)...

I get bored when i open the DivX 5 configuration panel from VDub...
If you don't like it don't use it... I LIKE IT :D

@jonny

just out of curiosity, what hardware do you have?

[jonny]

P3 @733
Matrox G400 (16MB)
192MB OF RAM
12GB HD

I encode (when is possible) at 704x432 and using always 2CDS.
I play with no post processing (correcting the aspect ratio with BSPlayer).

[Nic]

Jonny you could try www.freewebz.com if you have lots of troubles with angelfire.com...freewebz is pretty good (but bandwidth limit is around 500MB per month :(

-Nic

[philippas]

@ Jonny
A suggestion
If its possible to add a compressibility test in your program it would be great.
You could add a line in the avs script, while you open it, for the SelectRangeEvery command and a slider with the percentage of the test.
Then do a 1-pass encoding at quantizer 2 and get the size of the first pass so you can calculate the compressibility of the movie and then delete the file that was made for the test.(you could calculate the size of the first pass by reading the log that divx5 creates but it would be more complex and if they change anything in structure of the log file you would have to modify your program again).

Just a suggestion :)

[sillKotscha]

(sorry for my bad english... a german-"Kraut" is speaking ;) )

Hi fellows,

I was reading about this nice utility and downloaded the v.1.01 - unfortunately I can´t tell anything about my results with it, because it´s working at the moment (30% of the 1pass)... but I think i´ll work fine - just because of the fact that I trust in utilities made by genius heads like you (@jonny).

what about v1.02 - is there any place to download it, for example www.freewebz.com, like Nic sad?!!

(i tried copy&paste, but ttp://www.angelfire.com/wizard/div...vx5enc_1_02.zip is still dead!!)

Thanx a lot Sill

stay cool, stay clever - doom9 forever!!!

[jonny]

@nic & sillKotscha: thanks! :) I'll try www.freewebz.com

@philippas: Do you read in my mind? :eek:
I'm thinking about the integration of a compressibility test in my tool, but with a totally different approch... indipendent from the first pass log file. Read this if you are interested:

@ Jonny
@philippas: Do you read in my mind? :eek:
hahaha :D

I meant do an encoding at quality mode 100%(quant 2)using the script with the SelectRangeEvery command and get the size of the avi file produced not from the log file. SO say you did a 10% comp test and size of the avi file is 100mb then the size of the first pass is 100*10=1000mb and the quality is 1400/1000=1.4 =>140% (to fit in 2cd's) and 700/1000=0.7=>70% (to fit in 1cd)
The disadvantage is that you will have to store the avi file produced and then get it's size and then delete it, but the benefit is that it would complete abstract.


The advantage of your method, that you described in the other thread, is that you don't store the avi file but the disantavage is that you have to read the log file and calculate the average quantizer(a bit slow) and also the structure of the log files that divx5 produces is likely to change so each time the change the log files you will have to modify your program.

[Beave]

For the Webspace problem:

I suppose you have a flatrate. Then you could install IIS (Internet Information Server) from the WIndows CD. This sets up a WWW and a FTP Server on your computer at home. If you have a dynamic IP from your Provider, you could make an account at www.dyndns.org with a name like ftp://jonny.dyndns.org. Then everybody could connect to to your computer anonymously and get the file. Maybe it is not that fast then, but you don't need to upload anything anymore or you could make a little website in the WWW folder.
It could be a problem though, if too many people want that file at once and if you don't want to have your computer on all the time.

[jonny]

@philippas:
The method you described is good.
My method is good too (it is easy, average quantizer is stored in the first line of the "analyse.log" file). But is slow because is actually done with a 2-pass encoding...
I'll make some tests on both methods before deciding...
Thanks :)

@Beave:
:D:D:D I'm a 56K modem user :D:D:D
( I think apache server is better ;) )

[jonny]

@philippas:

I'm not sure the method you described work.
If i use a sample of 13 frames every x frames (like GKnot do), 1 artificial keyframe (for the scene change) will be introduced every 13 frames, and this will false the test...

Please tell me your opinions...

[TelemachusMH]

Just a quick question for jonny. Do you use a program to help you build the tk interface? If so, what program?

thanks,
TelemachusMH

[jonny]

@TelemachusMH:

No
Build the interface in Tk is simple (i think).
You can place the controls like in an html table (with the "grid" method) and for every cell of the table you can insert, if you want, another table (creating a "frame" widget).

It's not difficult, read the documentation for "grid" and "frame" and make your experiments.

I hope this help!

Bye
