Auto Gordian Knot: current version 2.55

[len0x]

Wanted to test new builds of XviD and DGMPGDec before stable release, so please do a stress test. Bugs that are not found before that have a good chance of not being fixed this time

I just had a question regarding Output resolution and hidden options.

I have a 720x480 MPG-2 input that is recognized as 4:3. I have even set the input resolution forced at 4:3 in the hidden option. I wish to have the output resolution at 320x240 (4:3 for viewing on my PocketPC). Unfortunately, for some reason AutoGK sizes the ouput to 320x208 and the output looked skewed.

Is there any way to force a particular output resolution in the hidden options?

Thanks.

For some reason in 2-pass mode BOTH of the 2 audio tracks I like to lay-down are coming-out as MP3, despite that normally I get AC3 as Track 1 and MP3 as Track 2 (using Auto output audio type). Here's a sample log, you can see that both audio tracks are the same size:

When I tried this again in 1-pass mode 75%, it resulted in the expected AC3 and MP3 tracks i.e. it worked fine. But I need to get 2-pass working again.

I wanted to revert to a pre-2.15b version but I just cleaned-out all my recent versions. Any ideas???

[len0x]

It was always like that in 2 pass mode: either both tracks are the same or in auto mode first one is AC3 only if target size is more than 700Mb...

No, if you want to crop wide screen movie to 4:3 or letterbox it - AutoGK is not a tool to go for.

Thank you; well, this explains it. I was attempting to encode a small portion (100Mb or so) of a movie to check encoding results.

I suppose there is a reason why "no AC3 if <700Mb" but ... well it might be nice to make 2-audio-track Xvids of movie trailers which are usually <100Mb. I will stick to single-pass for these I guess.

[len0x]

You just can't have AC3/MP3 combo for <=700Mb, but you can have AC3/AC3 if you selected that option in advanced settings.

[evil ryu]

What's the difference beetween the Koepi xvid (04/04/2005) and the version that you included in AutoGK 2.16b? Is AutoGK fuly compatible with the Koepi version?

[len0x]

Its celtic_druid's CVS builds (change log here: http://celticdruid.no-ip.com/phpBB2/viewtopic.php?t=4) plus MTK profiles done by him as well. Its fully compatible with official beta 2.

[3ncrypted]

Is it normal to get different compressibility results when switching between Xvid and Divx?(autogk 2.16b) For example I got compressibility of 107.70 with xvid and 77.04 with Divx 6.(all other settings identical)

[len0x]

yes, divx6 has compressibility of 20-25% lower than divx5 because of changed quantanization

[qknet]

Q1: The last time my output avi from AGK 2.16beta was confused by fuse.exe (to make divx media file with switchable subtitle) although I already check "stand-alone" support in Hidden option (MTK i think - what is the difference with ESS, btw?). The fuse's test FAILed but it proceeded anyway. Tecnical information shown in divx player shows that the resultant divx file is NOT certified.

Q2: If I already satisfied with the 1-pass output, how can I set it just to do 1-pass?

Use a quality setting for output.

Or read the guide

[len0x]

@qknet
First, fuse is beta product, second what codec and standalone settings are you using?

[len0x]

Give it a good stress test as this is gonna be a stable one soon.

[bourtzovlakas]

If you don't report problems with this latest version in the forum there is a chance that they won't be fixed at all and go to may-be-last-stable release of AutoGK.

Does this mean that the development of AutoGK will stop, after the next stable version?

[len0x]

yes...

[bourtzovlakas]

That 's too bad...



A huge thanks anyway for all the time and effort you put in this wonderful program....

[len0x]

Lets not dramatise for the time being. I'd rather suprise ppl with some unexpected releases than let everybody think I'm still actively developing it. I feel like its taken for granted that AutoGK will go on forever, so its time to stop that feeling

[Hobojobo]

And the Oscar goes to:

len0x !!!

Thank you for all the work and support.


Never say never...
