Guide To Divx Conversion Using Gordian Knot
« on: January 04, 2004, 09:06:00 PM »

I wrote it before AutoGK was released which I still haven't bothered to download and try.  If anyone would care to add to it themselves or send me details I'll be happy to edit and add it.  I just don't have the time to familiarize myself with the software and write one up right now.

I think the best thing for this thread is to simply point to the guides @ www.doom9.org (although the link is alreayd posted above).  The guides there are the best around and are updated accordingly, eliminating the need for new guides to be written.

QUOTE

1) Use DVD Decrypter to rip the Vob files to your harddrive (you only use Vstrip if the DVD material is on the HD already).  In most cases GK will select the longest stream and it will be the feature.  In the case of a DVD with multiple episodes on it, you will need to rip each one separately and then run them through the process below separately.

2) Now use DVD2AVI to create an AVI Project (in general use Force Film for film sources and disable it for video sources).  Preview the video and take note of the format on the right hand side (you will need it for cropping, resolution, as well as determining if interlacing will be an issue (generally TV video only)).  Select Save Project and let it run till finished.

3) Now open the project in GK with the open button on the lower left

4) What now adjust the resolution and use the autocrop/smartcrop all feature on the Resolution Tab.  Make sure you set it up correctly for true 16x9 vs. 4x3 (this was on the DVD2AVI tab).

5) Now adjust the bitrate on the Bitrate tab (DivX3.11 is the most compatible - newer versions are not necessarily better quality, simply better at estimating file size and potentially more legal - experiment and see what you like - if you use a HDrive no need to be as exact as if burning to a CD).  If you aren’t putting them on CDs - disable the Split into Final Cds option.

6) In this example only use Audio A - select the proper audio track (you may have to look at the text file created by DVD2AVI to determine which one – it’s in the folder with the rest of the source files).  If you want MP3 sound in a smaller size set the bitrate for it otherwise leave the larger AC3 file if you want 5.1 sound or the highest quality. - In the interleaving section of this tab select either the 1xAC3/Constant Bit Rate MP3 or the 1x Variable Bitrate MP3 (for MP3 variable is a better use of space).

7) At this point you watch the bottom panel near the open button to make sure the Bits/(Pixel*Frame) settings are in the proper parameters (>.20 in general with higher for better quality - below this limit and most movies don't look very good) - you go about this by adjusting the Total File Size in the upper right (bigger means higher bits) as well as the resolution if you are flexible here (higher res means lower bits per frame) - they basically work inversely to each other.  Higher resolution is not necessarily better when using lower bit rates since the errors will be magnified over a larger area.  This just let's you balance out the tradeoffs in encryption  Use lower quality and less space for movies you don't care about too much (as well as lower quality sound).

8) At this point you go to the open window with the video in it and select Save and Encode.  Genereally keep everything stock and use Lanczos (sharp) unless doing low quality.

9) If you are using a non-film source and it had interlacing when you created a DVD2AVI project you select Field Deinterlace in this window.

10) An option at this point is to run the Compressibility Check (basically runs a check on the Bits/(Pixel*Frame) since every movie is different.  This is generally pretty accurate so run one at 3-5% - this will take a bit and use 5% if you are new to this to get a feel for different sources and accuracy.  This can screw up for cartoons and especially for cartoons with actualy video of people overlaid on top - just something to be conscious of since it will give you an outrageously high quality estimate and the final project will have artifacts so be aware and don't trust the check fully for sources like this.

11) Now if you look below the Bits/(Pixel*Frame) there is a new number to the right of the Load button.  The first % is used to establish parameters (going over 80% is wasteful and less than 45% does have great quality - for this example keep it over 50% as a standard).  This is important since some movies can really be compressed and others aren't as good.  Tweak your File Size and/or Resolution settings until this new % number is in the range you want.

12) Almost done - click Save and Encode on the window you used for the Compress Check

13) Real simple - the Audio source file should be the one you selected.  For AC3 sound you select Just Mux.  For Mp3 set the bitrate and use either constant or variable as you determined before.  Now go to the panel for your Codec - in this example DivX3 - everything should be setup (I use Multipass Encoding which should already be enabled) - don't touch anything just click Add Job to Encoding Queue.

14) Either Encode now (do this until you get comfortable with your results) or begin again with another movie and just keep adding them to the queue.  Run in batches sometimes as GK runs nicely in the background although you can always up the priority of it for more processor usage if you aren't doing anything else.

15) Done - the file you want is the AVI that doesn't say "Movie" on the end since that one has no sound attached (it's smaller in size just look).  FTP it to your XBox - share it under a Relax share, whatever - make sure it works and delete everything besides the file you want to use.

16) Voila!

I'm assuming you at least own the movie (doesn't everyone 25+ own Top Gun - even chicks like it).  If not, please erase it because open talk of piracy will get this thread deleted.

Come on, Top Gun wouldn't even be worth pirating....how could you assume such a sick deed could even be considered!
