Megui H.264 Conversion Guide
Updated: 07/06/2007 09:24 AM

MeGUI is one of the newer tools that has been designed with H.264 encoding in mind, while supporting other types of conversion, such as XviD. This guide shows you how to encode a H.264 (MP4) using MeGUI from a DVD as the primary example (instructions for converting other types of video files are also included).
This guide is aimed at intermediate users, basically users that are familiar with DVD conversion/backup and want to experiment with H.264 and MeGUI. As such, basic knowledge of DVD ripping and conversion is required, although brief instructions will be provided in any case.
Software you'll need (all freeware):

The first thing you need to do before you can even install MeGUI is to download and install Microsoft's .NET Framework version 2.0. It's a fairly large file and installation could take more than half an hour. Once you have it fully installed, you can now go on and download MeGUI.
Download MeGUI and install it. Start it up and most likely, it will prompt you to update the software used by MeGUI - click "Yes" to launch the update Manager.
MeGUI: Update Prompt

MeGUI: Updater


Press the "Update" button to start the update process - MeGUI will automatically download and launch the install for the required software. You will most likely get a "1 file had problems" error, this is because the "neroaacenc" software cannot be downloaded automatically from MeGUI due to copyright reasons (it is freeware, but you need to go through Nero's software agreement first before you can download it). If you need to update "neroaacenc", go to this page, select "Agree" to download the ZIP archive and extract the .exe files (in the win32/ folder in the ZIP archive) to your "megui\tools\neroaacenc" folder (eg. "c:\program files\megui\tools\neroaacenc\neroaacenc.exe").
When all the updates are completed, you can now close the MeGUI updater.
If you are converting from a commercial DVD source, you will need to rip the DVD to your hard-drive using RipIt4Me. RipIt4Me (and tools required by it) also needs to be installed - you can either follow the instructions in the RipIt4Me guide or follow step 1 of our Quick and Dirty DVD Backup Guide (you can skip installing ImgBurn and DVD Shrink, just install DVD Decrypter, RipIt4Me and FixVTS).
And we're now finished with the installation. If you are converting from a commercial DVD source, please proceed to the next page/step (Step 2: DVD Ripping). If you are converting from MPEG-2 (but not from a commercial DVD), please skip to step 3 (Step 3: D2V Creator). For all other video formats (eg. AVI,

This step will use MeGUI's D2V Creator tool to create a D2V file needed for MeGUI/AviSynth to handle MPEG-2 files. This step is required only for MPEG-2 files - all other types of inputs do not require a D2V file and can be loaded straight into AviSynth and therefore, you can skip this step and go to the next page/step (Step 4: AviSynth Script Creator).
Start MeGUI. I like to first clear the job queues of previously finished jobs. This is optional, but it might help to make things clearer. To do this, click on the "Queue" tab and then click on the "Clear" button.
From the "Tools" menu, select "D2V Creator". In the "Video Input" section, load the first ripped VOB file of the movie titleset (the rest of the files in the set will be loaded automatically). You will get an error message about not being able to find DVD Decrypter generated info files, this is fine (as we did not use DVD Decrypter's IFO mode) and press "OK" to skip this error.
MeGUI: D2V Creator
In RipIt4Me's step 1, you were asked to take note of the audio track numbers. We'll need it here select which audio track(s) to demux - you can select more than one track if you want the encoded file to have multiple audio tracks. Alternatively, you can just select the demux all the tracks and then choose the correct audio track(s) later on.
The default save directory is the same directory as your loaded DVD VOB files - change this if you want to. Select both the "On completion load files", "and close" checkboxes and press the "Queue" button. You are now returned to MeGUI - click on the "Queue" tab and press the "Start" button to start the D2V creation. When processing has finished, the status of the queued job will read "Done" and the created D2V file will be loaded into the AviSynth Script Creator ready for the next step. This can take a while, so please be patient - the status window's progress bar may not move, but don't worry, DGIndex is working
