MeGUI Video Encoding Guide

Summary: It is more difficult to use MeGui to convert a video file than Handbrake. But I find a detailed tutorial in a forum for you. And I also recommend you a video transcoder that is much easier to use to convert videos. 

MeGUI is the most comprehensive GUI based ISO MPEG-4 solution. Cooperating with different applications, MeGUI presents more powerful functions to encode videos. However, it is a little more complex to convert video with MeGUI than Handbrake. So there are many people proficient at computer sharing their experience on encoding videos with MeGUI.


Below is a specific tutorial on how to encode videos with MeGUI. This tutorial is posted by Suleiman Shouaa in a site called originally. The original post is here.


Now, let's see how to Encode Videos using MeGUI?


Tools needed:

MeGUI - get it here
Nero AAC Encoder - get it here

Setting up MeGUI (one time only)

1) Install both of the above programs in folders of your choice.
2) Boot up MeGUI and go to Options -> Update and make sure everything is up to date.
3) Go to Options -> Settings -> External Program Configuration. Tick "enable NeroAacEnc" and press the "..." button then navigate to the folder that you installed Nero AAC Encoder to. There should be a file called "neroAacEnc.exe" there. Press Open. Then press Ok. Now you can make use of the AAC Encoder

Getting down to business

MeGUI is a bit more complicated to use than Handbrake, but once you get used to it it's np. I'm going to assume that all you want to do is "link" consecutive fraps files of the same engagement together (after fraps makes a 3.9gb file, it continues with a new file) and then re-encode, ie. do no editing. The same general procedure can be followed if you're using Sony Vegas or whatever to actually edit the files and then throw out a single AVI file - just remember to output from Sony Vegas as uncompressed AVI. 

1) MeGUI works by following a script that you create, detailing what you want it to. Whilst this normally involves manually typing in commands, MeGUI has a script creator for you to use! Go to Tools -> AVS Script Creator in the main MeGUI menu. 

2) To make the next few steps easier, create a new folder somewhere and put all the fraps avi files of a single engagement in there. In chronological order, rename them to "1.avi", "2.avi" etc. This will reduce your workload in a second..

3) Back on the AVS Script Creator window, click on the "..." next to input. Navigate to "1.avi" of the fight you want to re-encode (ie. the very beginning). When it asks you how you want to open the file, choose "AVISource". A preview of how it'll look once it's encoded will show up, along with default settings. Ensure that "Crop" and "Resize" aren't ticked.
4) Go to the second tab of that window called "Filters" and change "Source Type" to "Progressive" if the input is a fraps recording. Next, go to the third tab called "Script". If your fraps file contains audio, then replace "audio=false" with "audio=true". Now, press Save to save your script (default name is 1.avs, if you've followed my avi naming convention)

5) The rough draft of your script is done. However, if you want to string together multiple AVI files, navigate to the folder where you stored the raw fraps files and find "1.avs". Open it in Notepad. It should say something like

AVISource("E:\Fraps\Inputs\ARRRRRRRRRRMOUR HACs\1.avi", audio=true).AssumeFPS(30,1)  #deinterlace  #crop  #resize  #denoise    ConvertToYV12()

The "ConvertToYV12()" might not be at the end, if not copy & paste it in.

6) Now to string together the files. Copy & paste the first line but add a "++" to the end of the line BEFORE you copy & paste. Obviously, change the name of the file with each new line. Hard to describe, but it should look like this...


Note that ALL of the file names are in a single line, with no "++" at the end. If you have a "++" at the end, then it'll throw an error as the "++" tells MeGUI to append to that line, but there's no file name specified. As you can see, if you have your files called "1,2,3,4,5.avi" etc then it's much easier to ensure that they're in the correct order.

7) Almost done! On the main MeGUI screen, ensure that "1.avs" is the selected AS script". You can change the name of your video output if you want. Default settings can be changed at encoder settings -> config, but "Targetting Quality = 20" is a good compromise, anything above and the quality increases, but file size increases much faster. 

8) To add audio, in the main MeGUI window, under audio select Audio Input as the avs script file you made (make sure that audio = true for all input files mentioned in that file). Choose Encoder settings as "Nero AAC: NDAAC-LC 64kBps"

9) Click AutoEncode in the main MeGUI window and you should be done! If it asks you how you would like to encode, select "no target size (use profile settings)" and choose MKV or MP4 as your container. Then click "Queue" and wait.


Yes, still looks a little complicated. For those who have no experiance on video conversion, these steps are something complicated or difficult to understand. So here we introduce you a much easier to use video transcoder to help you encode video with ABC.
