    it looks like you need to change the settings on your in-game recorder or get a new one. upload in 720p to get HD

    1280x720 at 3mbps to get HD

    but pls use 30fps when rendering or it will look laggy

    you have used 5 mbps...

    and btw. 25 fps is good enought but it really depends on ammount of fps frapsed directly from game

    let me put a guide that i found here, the video i am making here got a real good quality after rendering (i take no credits for this guide)
    http://www.mmorpgforum.com/showthread.php?p=87267
    First things first.

    This guide focuses on encoding only! It will tell you everything you need to know about rendering to H.264 with Sony Vegas and MeGUI, but nothing on how to set up your Vegas project, adding effects etc.

    My knowledge is based on other guides and tutorials I’ve been looking up over the past few weeks. Don’t expect too much detail here ^^. There’s also been a video tutorial uploaded on warcraftmovies.com about it. However MeGUI has changed slightly and the video tutorial might not be as accurate as it used to be. That’s why I wrote this guide, and because I’m sick of watching movies made with hours of editing, but then being rendered with some lousy .wmv format, having 500MB for 15 minutes at a resolution of 800*600 and still looking all blurry.




    1. This is what you’ll need

    • Some free disc space
    • MeGUI
    • AviSynth
    • Lagarith Lossless Codec
    • Time
    • and of course Sony Vegas (I’m using Vegas Pro 8.0, but any version should be fine)




    2. Downloading / Installing

    Install all the programs listed above using the custom settings. (and for god’s sake, don’t ask me where to get Sony Vegas from … ) MeGUI will most likely start automatically and ask for an update. Just abort everything and close it, you’ll deal with it later.




    3. Encoding your video with the Lagarith Lossless Codec

    MeGUI will require an AVI video file in order to create a high quality mp4 file. For that, you want to use an uncompressed video format. That’s what you will need the Lagarith Lossless Codec for.

    Open your Sony Vegas project and select everything you’d like to render. (Just the way you always do before rendering.)

    Now go to “File” and “Render As…”

    In the drop down menu select “Video for Windows” and click on “Custom…”

    In the “Project” tab select “Best” for the video rendering quality.

    In the “Video” tab be sure to match up everything with your project settings. This includes “Frame size”, “Frame rate”, “Field order” and “Pixel aspect ratio”. In the “Video format” dropdown select “Lagarith lossless codec” and click on “Configure…” Check “Enable Null Frames” and “Use Multithreading” (You should leave the multithreading unchecked if you’re using a single core processor.) “Always Suggest RGB for Output” should stay unchecked. In the dropdown menu under “Mode” select “YV12” and hit “OK”. “Interleave every (seconds)” should be checked and at “0,250”. “Interleave every frame” should be unchecked and “Create an OpenDML (AVI version 2.0) compatible file” should be checked.

    In the “Audio” tab “Include audio” should be checked. With "Audio format" at "PCM Uncompressed", "Sample rate" at 48.000, "Bit depth" at 16 and "Channels" at "Stereo".

    Hit “OK”! You can now save your video file, BUT this is where you’ll need the extra disc space. Since it’s a lossless compression of your movie the AVI file will be huge. For instance, a one minute long clip at 30 FPS with a resolution of 1680*1050 has around 1,5 Giga Bytes. Of course, the file size will vary depending on the FPS, resolution the amount of still images etc., but better be on the safe side and leave more than enough free disc space for the AVI file. (HINT: you can leave the video file name as “Untitled”, it may save you some time in the future, you’ll soon know what I mean)

    The rendering may take a while. When it’s done you can close Sony Vegas.




    4. Setting up MeGUI

    Start MeGUI and update it. Simple push the “Update” button, you don’t have to check or uncheck anything. MeGUI will update regularly, but don’t worry; the updates probably won’t affect the user interface. Once updated a “Preset Importer” will pop up. These presets define the quality and rendering speed of your movie. For this guide you only need to import the presets beginning with “DVXA-HD” and none of the audio presets, but I’d recommend you to import all of them, just in case you’d like to try some other rendering methods besides those I will suggest you. MeGUI will restart, and that’s it!




    5. Creating an AviSynth Script and adding the Video


    Now that you’ve set up MeGUI you’ll need an AviSynth Script. The script basically tells MeGUI what and how it has to encode.

    To make an AviSynth script open MeGUI (Unless you’ve never closed it. :P) On top of the main window press “Tools” and then “AVS Script Creator”. In the new window click on the three dots next to “Video Input” and select your newly encoded AVI file. A window should open showing you a random part of your movie. You can close the window, it only shows you if the file could be loaded properly or not.

    Now go to the “Edit” tab. The very first line should say something like: "AVISource("C:\Untitled.avi", audio=false)”. Change “audio=false” to “audio=true”. Otherwise MeGUI won’t use the audio of your AVI file and you’d have to add the audio separately. Click “Save”. Again a window opens showing you your movie, close it. An AviSynth Script-File was now added into folder of your AVI file and the script was automatically loaded into MeGUI.

    You can use this single AviSynth Script for all of your future encodings. As long as your uncompressed AVI file’s name stays the same and is in the same directory. Thereby you can simple click on the three dots next to “AviSynth Script” in the main window to add your script, and won’t have to create a new one over and over again.




    ! Extra Info !

    Many people like to encode their movies as a High Quality and a Normal Quality version. To do so, simple add a line to the AviSynth script. You can create or a new AviSynth script like I explained before, or just edit an existing by opening the AviSynth file with the Windows Notepad. I myself have two Scripts. One to encode at full resolution. Which looks like this:

    AVISource("C:\Untitled.avi", audio=true)

    And another one that has the addition line, like this:

    AVISource("C:\Untitled.avi", audio=true)
    BicubicResize(1008,630)[/code]

    All the second line does is to encode the movie at the resolution of 1008*630.




    6. Video-Settings

    Still at the “Input” tab in the main window click at the “Encoder settings” dropdown. In there are all the presets you’ve added when setting up MeGUI. You can choose between several presets, but there’s one I would recommend. It’s the one called “x264: DVXA-HD-Balanced”. These presets define the quality and mainly the encoding speed of your final movie. However, since you should only use the “DVXA-HD” presets, the quality is somewhat the same. That’s why I suggest you to use the “Balanced” preset. The encoding time is bearable and the video quality is good too. (For instance: I tried the “DVXA-HD-Insane” preset to render a one minute long clip, and it took MeGUI two freakin’ hours to encode it! But there was hardly any visible difference to the “DVXA-HD-Balanced” version of the clip.)

    At the “File format” dropdown be sure to have MP4 selected.




    7. Bitrate / File Size

    Everything’s set, hit “AutoEncode”! You’re almost done.

    In the “Container” dropdown be sure to have “MP4” selected. You may also change the file name.

    Last, but not least, “File Size” or “Average Bitrate”. Either you click on the little arrow next to “File Size” to define the size of your movie or you can try an “Average Bitrate” and look for yourself how big the video would become. It all comes down to File Size or Quality. Simply said, the more the better. Still, nobody wants to download 800MB for a 10 minute movie. My rule of thumb is something around 30MB per minute at a resolution of 1280*1024 with 30FPS. This would cause a 20 minutes long movie with a pretty high resolution to have around 600MB. For me, totally acceptable, but that’s for you to decide.




    8. Encoding

    Once you’ve selected your desirable File Size or Bitrate hit “Queue”. An error might pop up when encoding at very high resolutions, but you can ignore it and simply click “Yes”. Now go to the “Queue” tab next to “Input”. In the bottom left corner hit “Start” to finally start the encoding. That’s it! When done encoding you can click on “Clear” to clear the log.


    It may seem a bit complicated at first, but since you can use the same AviSynth Script over and over again, this method will become pretty easy and fast to manage. With all the presets made in Sony Vegas and MeGUI it all comes down to four easy steps:

    Step 1: Encoding your movie to an AVI-File
    Step 2: Adding the AviSynth Script to MeGUI
    Step 3: Selecting the File Size or Bitrate
    Step 4: Encoding


    Enjoy! Feel free to correct me or give suggestions and I will edit this guide if necessary. After all I just summarized what I know from other guides, and even if this may not be the most effective way encoding to H.264 I've been pretty happy with the results.

    Oh.. and of course, excuse my half-good english

    x264 ... you can't play it in common video players so that is quite decreasing ammount of potencial spectrators....
