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):
Step 1: Installation
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.
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,
Step 2: DVD Ripping
Step 3: D2V Creator
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.
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
Step 4: AviSynth Script Creator
Step 5a: Video Encoding Options MP4
Step 5b: Video Encoding Options XVID
After the AviSynth Script Creator window closes, it will be entered in the AviSynth Script box on the Input tab. Below that is the output file. Click the button to the right of it to change the location or name. Select the dropdown menu next to Codec and set it to XviD. File Format should be set to AVI, MKV, or RAWASP (MP4). To select a Video Profile, determine what percentage of original DVD's bitrate will be used for the XviD encode. If you're not sure, compare the combined size of the VOB files to the intended final size of the XviD. The profiles are named by what amount of compression they're designed for. For example, XviD '>90% comp. check' means it's for encodes that are 90% as big as the original or more. Find the largest percentage that's smaller than or equal to the amount of compression your encode will have. Each compression level will have a fast and HQ option. As the names suggest, one will give you faster encodes, and the other a little higher quality.
Step 6: Audio Encoding Options
Now it's time to set up the audio encoding options. If you've followed this guide for DVD conversion, then the demuxed audio track we selected in the D2V Creator should already be loaded in (if not, load in the .ac3 file that was created). If you are not converting from a DVD source, then you can either load in a separate audio file or if you edited the AviSynth script (set "audio=true"), then load in the AVS file into the "Audio Input" section (meaning both video and audio inputs are the same AVS file). Repeat if you want a second audio track by clicking on the "2" select option.
Now we select an audio codec to use. I prefer AAC audio, especially with H.264 as video - AAC is to MP3 what H.264 is to DivX/XviD, better compression + better quality. So which audio codec should you use? I prefer ND AAC (Nero Digital), so select it if you agree with me. We can now choose an audio profile from one of the "NDAAC" options. "NDAAC-HE-64Kbps" is the one I like, as it will give you roughly the same quality as a 128 Kbps MP3 file. You can select one of the "HEPS" (HEv2) profiles if you really want a small file size. The "LC" options offer better compatibility (eg. with iPod/iTunes), but at the cost of file size (still smaller than MP3s though).
Step 7: AutoEncode and starting the encoding
We're nearly finished. Press the "AutoEncode" button to launch the Automatic Encoder setup windows.
This is pretty straight forward - just specify the output size of your video file (and make sure the Container is set correctly, to "MP4" for the purpose of this guide). The output location can be changed as well - this file will be the final output file that you want, so make sure you remember where you put it and don't accidentally delete it when cleaning up (I like to put this file in a different folder to all the other files, just in case). Press the "Queue" button and all the necessary jobs will be added to the encoding queue.
Click on the "Queue" tab and all the jobs should be listed there. An explanation of the queued jobs shown in the screenshot below:
- job1: D2V Creation (already finished)
- job2-1: Encoding audio track 1
- job2-2: Encoding audio track 2
- job2-3: Encoding video, 1st pass
- job2-4: Encoding video, 2nd pass
- job2-5: Muxing audio and video to MP4
When you're ready to start, press the "Start" button to start the encoding and when it's all finished, your MP4 file should be ready. You can delete all the other files, unless you plan on making more encodings from them.
We're done
