Guide to Creating a Rifftrax AVI 01 – Prelude I love RIFFTRAX! And I love Movies! But over the past few years, I migrated all my DVDs from the actual disks into a media center that I set up. To do this, I converted them all to AVI files using the Xvid codec. When I first started buying Rifftrax mp3s, I just opened up the movie and the mp3 into separate media players… but this means timing bathroom or snack breaks with DisembAudio lines so I could re‐synch them when I got back. It’s not TOO difficult, but I thought it would be much nicer if I didn’t have to worry about such things. After reading the handy “UNOFFICIAL Rifftrax DVD Creating Step‐by‐Step Guide” (http://www.rifftrax.com/smf/index.php/topic,413.0.html) on the Rifftrax Forum, I decided to mix the process I was already using with some of the ideas in that thread. And now I’m sharing my process with the entire world. It’s actually very simple to do, it just takes a lot of time for some of the steps to process. note : for this guide, I’ll be ripping and mixing the movie Independence Day To start with, as a frame of reference, here’s my system set‐up to give you a general gauge for how different the times may be on your computer: My system: 3.19 GHz, Pentium 4 2 GB Ram XP Pro – SP2
02 – Software You’ll need to install some software before you start (all free). This guide is written using fresh installs of everything. So the assumption is that no settings have been changed since installation.
Required Software: K‐Lite Codec Pack Full (http://www.codecguide.com/features_full.htm) – this includes all the video and audio codecs you could ever need. Just download, install, and forget about it. DVD Decrypter (http://fileforum.betanews.com/detail/1011845169/1) – this is the defacto standard for ripping DVDs to your hard drive, but it’s no longer in development, and some newer DVDs won’t work with it. You can try DVDFab (http://www.dvdfab.com/free.htm), but I’m only covering DVD Decrypter in this guide. Auto GK (http://www.autogk.me.uk/index.php?name=Downloads&d_op=viewdownload&cid=1) – this is actually many different bits of software, using a single front‐end GUI. When you install, there will be a few times where it will ask you for an installation directory. The default locations should be fine. Audacity (http://audacity.sourceforge.net/download/) – free audio editor. I’m using version 1.3.3 Beta, because it includes an “Auto Duck” effect, which will lower the volume of the movie audio when the Riffers are talking, but that’s totally optional. The latest Stable version should work great if you don’t need that. AVI‐Mux Gui (http://www.alexander‐noe.com/video/amg/) – this actually adds our audio tracks to the video
03 – DVD Decrypter After everything’s installed, put your DVD in your computer’s DVD drive and fire up DVD Decrypter. You should be greeted by this screen:
Depending on the DVD you may get this pop‐up first:
Just click “OK” and the pop‐up will close.
Now, a lot of these things I’m about to describe are automatically done, and should be the default settings of DVD Decrypter. But, just in case something got changed, here are some settings to check:
Make sure “Mode” is set to “File”.
If you have multiple drives, you’ll need to make sure your DVD drive is chosen.
Click on “Tools” and then “Settings”
These are the default settings. Just make sure yours are similar, then click “OK”
Choose the destination for your ripped DVD. I’m usually fine with the default location.
Highlight everything in the right window, then click the start button to begin the Rip. Below, is what DVD Decrypter looks like while it’s ripping. When it’s done, simply close the program. It took me about 30 minutes to rip ID4.
04 – Auto GK This is the workhorse of the entire process. After getting everything set‐up, it may take 3 to 6 hours for the whole thing to finish. However, it’s all automated, so once it starts, you can just let it go. Now open up Auto GK, and you’ll see this main window:
Now, select Input file to open up a file dialog.
This can get tricky. You’ll need to locate the largest VOB files in the VIDEO_TS location where DVD Decrypter saved your DVD. You’ll notice in this case, all the files that start with “VTS_04_” are the largest. This generally means that THIS is your main movie. Select the file that starts with “VTS_04_0” but is an “IFO” file (NOT the VOB). Click “Open”.
In the case of ID4, since there’s an Extended Cut, as well as a Theatrical Cut, you’ll get this pop‐up:
Since I know that they’re Riffing on the Theatrical Cut, choose PGC 2 (with the shorter length)
Select Output file, and choose the location to save your final AVI
I’m saving mine in the ID4 folder, and naming it “ID4.avi” .
These next few steps can be done in any order, I just do them from top to bottom for simplicity’s sake
Select the audio track to encode. The top ones are usually the main movie’s audio. I’m choosing the 2 channel track, mostly to keep file size down and because I don’t have a fancy home theater setup. Feel free to choose any track you want, as the process is still the same.
Select the output size. I usually choose “700Mb”, but since ID4 is almost 2 and half hours, you may want to choose “896 Mb” or higher. It’s really just personal preference. A higher size means better quality, but it also uses up more disk space. Also note, it says “1 CD” but after we add the Rifftrax audio, the file size will go higher than 700 Mb and WON’T fit on a single CD. Since I keep everything on a hard drive, it doesn’t bother me… but if you’d like keep it on a single CD, choose “Custom size” and enter “550 Mb”.
Click Advanced Settings, and the Advanced Options box will pop‐up. I usually keep the “Output” setting to “Auto”. The Codec I use is always XviD. You can use DivX, but I’ve just found XviD to look better after encoding. When you’re done, click “OK” to close the box.
Once everything is set, click “Add Job” and you’ll see the movie in the “Job queue” box.
Highlight the movie in “Job queue”, then click “Start”. Now you should probably just leave your computer alone for a few hours and let it work. Below are a few dialogue boxes that will pop‐up, just so you know that it’s working.
Right after you hit “Start”.
A DOS Prompt where the audio starts to encode.
After the Audio is done, in your taskbar you’ll see the VirtualDub Mod start encoding the video and the percentage complete. It does 2 passes, so you’ll see it go from 0% to 100% twice.
We’re done with Auto GK! With my non‐Riffed DVDs, this is usually the end of the process. Though, on a few occasions, the audio is not totally synched up, but I’ll explain how to fix that in the AVI‐Mux GUI section.
05 – Audacity Now, we need to synch up the movie’s audio with our Rifftrax. Launch Audacity.
Then go to the folder where you saved the AVI of your movie. In that folder, there should be another folder named “agk_tmp”. Open it up.
Locate the mp3 file. Then click and drag it into the Audacity window.
Wait while it imports the mp3 (5‐7 minutes). When it’s done, go ahead and save the Audacity project, just in case. Then, find your Rifftrax mp3 and drag it into the same window and wait again while it imports. When it’s complete, you should have something like this:
Mute the movie’s audio track, then put the cursor over the Rifftrax about 2 minutes into the track. Find the part where Mike says “1‐2‐3 pause”, then put the cursor right after that. Then click and drag all the way to the beginning of the track, so that approximately the first 2 minutes are highlighted. Click the “cut” button to delete that section.
Using the Rifftrax readme file, locate the first DisemAudio line and synch it with the movie line (yes, I’m really using Casino Royale’s Readme… because ID4 isn’t out while I’m assembling this). At this point, I listen to the entire Project and set the volumes of each track so that I can hear the Riffers over the movie.
OPTIONAL AUDIO STEPS
Once you have the first DisembAudio line synched, you can then “Silence” all his lines, by using the readme file, highlighting DisembAudio’s lines and clicking “Silence”.
After doing this, make sure the movie’s main audio track is the TOP track. Highlight it, then go to the “Effects” menu and choose Auto Duck.
I set the fade times to be fairly quick at .13s, and I decrease the volume even more. This is just a personal preference, since there are some times where they Riff on a line quickly after Riffing on another line. Click “OK” and take another break.
Back to nonOptional Steps Once you’ve got the audio all synched‐up and sounding good, it’s time to export the entire project to an MP3. Choose “File” then “Export…”.
I usually save it with everything else I’ve done. You can also click “Options” to change the MP3 quality. I’m usually satisfied with 128kbps/Constant/Stereo. Click “Save” and…. Once again… WAIT. When it’s done exporting, you’re 95% of the way done. Now we just need to mix the audio with the video.
06 – AVIMux GUI Fire up AVI‐Mux!
Go to the folder where you saved ID4.avi, then simply drag the file into the top box. Then click the button “generate data source from files”.
You’ll see two things in the bottom window. The video track and the audio track. Now, drag the Rifftrax audio that was created in Audacity into the top window as well.
It will prompt you to check if it’s a CBR (constant bit rate) mp3, but we really don’t need to, so click “No”.
So we’re ready for the final stage. You can check the “settings”, but I’ve always just used the default ones. Also, I will sometimes take the Rifftrax’ed audio file in the lower window, and drag it to the top of the list. That way, when you play the whole movie, the Rifftrax will be the default audio. Otherwise, you’ll just need to change which audio stream you’re listening to when you start the movie. Click “start”. Then in the “Save as” popup, choose a location to save the final movie.
This is one of the fastest steps in the process. After about a minute, YOU’RE DONE! The whole process usually takes me about 6 hours, but most of that is just letting things process. To watch, I always use the VLC player. That way you can have multiple audio stream AVIs, thus you have the original movie with original audio, AND the Riffed audio all in one file. I’m sure there other great media players out there though. HAVE FUN!!!
Quick AVIMux addendum On occasion (it’s only happened to me twice), you’ll find that the audio for the movie is a little off synch. It’s fairly easy to fix this, though it takes some experimentation.
While watching the movie, try to estimate how far off the synch is. Then highlight the audio in the lower window, and enter the number of milliseconds in the right side “delay(ms)” box. Click “start” and then re‐check the video. If it’s still off, keep adjusting until you get it right. In the couple of times it has happened to me, I only needed a few hundred milliseconds of correction, so 180 may be a good place to start. Keep in mind that after you make the Riffed audio, you’ll need to delay THAT audio track the same amount of time.
