JBMM Video Basics
VirtualDub is a program for convering AVIs and MPGs to AVIs. That seems a little silly. Why convert an AVI to another AVI? Well, not all AVIs are the same. For an AVI to work on the JBMM its CODECS must be right.
What is a Codec?
Codec is short for Coder/Decoder. On computers, video and audio can be encoded in many ways. A codec is the software for encoding and decoding audio or video. Any movie, tv-show, music video, etc..., has two parts - audio and video. You can select the codec for each separately.
The JBMM has very limited codec support. Specifically it supports two codecs: MPEG4 (DivX) for video and Mpeg-Layer-3 (MP3) for audio. Your AVI must have both the video and audio codecs right in order for it to work on the JBMM (if just the video is right it will work but you'll have no sound). Unfortunately, this isn't the only thing you have to do to make an AVI work on the JBMM
What Makes an AVI JBMM Compatible?
This isn't as simple as we would like, but it isn't terrible. Below is the list of everything that has to be right for the JBMM to play the video:
Audio: MP3 audio 160kbps VBR or less.
Video:
Mpeg4 "simple profile"
352x288 ("cif") or lower resolution
Width and Height must be a multiple of 4
It may sound a little complicated, but it isn't that bad.
Getting Started
First you need to download some files:
VirtualDub 1.4.10 (official website) Download the Zip and extract all files into their own folder (if you can't read zip files, get Winzip).
DivX 5 DivX 5 is probably the easiest codec for Mpeg4 - and you can get it free (download and install it - free version is fine).
Lame MP3 is one of the highest quality MP3 encoders available. Unpack the Zip into a temporary directory. Right-click the LameACM.inf file and select install.
SmartResizeFilter VDub comes with a resize filter, but its quality isn't great. Use this one! Make a sub folder in the VDub directory called "plugins" and extract this Zip there.
Now lets see if you got those all installed right
. Run VirtualDub (by double-clicking the VirtualDub.Exe icon).
DivX5 Check:
Go to the Video Menu
Select Compression
In the left pick-box, see if you can find: DivX 5.02 Codec
Select it.
Press the Configure Button
You should see a config screen with a nice big DivX logo
Lame MP3 Check:
Go to the Audio Menu
Select Full Processing Mode
Select Compression
Find LameMP3 in the list on the left.
Now a whole list of options appear on the right.
Smart Resize Check:
Go to the Video Menu
Select Filters
Click the Add button
Find Smart Resize by Donald Graft (thanks Donald!)
Select it and click the Ok button.
If you were able to go through all the checks, you're set to go!
Converting a File with VirtualDub
Start by opening the file. Go to File->Open or simply drag and drop an AVI or MPEG to VirtualDub. Sometimes VirtualDub can't open a file, but right now we aren't going to deal with that. If your file can't be opened, try another.
Now, lets see some info on your file. Select File->File Information. It should look like this:
You will see that there are two problems with my AVI - for playing on the JBMM. First, my file's resolution is 640x360. Second, my Audio Codec (the Compression line of the Audio stream section) is Windows Media Audio.
Setting Up the Video Conversion
If your video is already in DivX 5 format and is less than or equal to 352x288, you can choose not to re-encode your video. You can select Video->Direct Stream Copy. This is much faster, so if you can, you should probably use it. But, most the time you can't
. If you can't, make sure Video->Full Processing Mode is selected.
If your video is bigger than 352x288 (in any way) you must resize it. You need to add the smart resize filter.
Go to the Video Menu
Select Filters
Click the Add button
Find Smart Resize by Donald Graft (thanks Donald!)
Select it and click the OK button.
If your video is small enough, go to the Filters dialog box and remove the resize filter - this will make things faster.
If you are not sure, or if you are going to convert lots of videos of different sizes, go ahead and leave this filter setup. You can't go wrong with it on
.
Setting Up Smart-Resize
When you Click OK to add the smart resize filter, you will see the following box:
The easiest and best settings are the ones I've shown in the picture. Your input width and height will be different than mine, but everything else should match. The Filter mode selects the quality. Precise Bicubic is the best and slowest. Probably all of them are fine except for the first one: nearest neighbor (that is what the built-in virtual dub filter does). If you follow all the settings above, you won't have to worry about multiples of 4 or anything else related to size. This will (should) just work
.
Setting Up the DivX Video Codec
The last step in setting up the video end of the conversion is to setup the DivX codec:
Go to the Video Menu
Select Compression
In the white box, see if you can find: DivX 5.02 Codec (or newer
)
Select it.
Press the Configure Button
Now you should see something like this:
I suggest you select 1-pass encoding (not 1-pass quality-based) under the Variable bitrate mode pull down. Then you can select your bitrate with the slider or just type it in. Higher bit rates mean higher quality. Lower bit rates mean smaller files. I suggest 500 most the time. Values from 250 to 1200 seem to be useful. More or less than that doesn't seem to make much difference on file size on the low end and quality on the high end.
There are more settings under the other tabs and with the Pro version of DivX. I suggest you leave them at their defaults for now.
Setting Up the Audio Conversion
VirtualDub, unfortunately, doesn't make this as easy as it could be, but it isn't that bad. Here goes!
If your source file already has MP3 audio, then you can select Audio -> Direct Stream Copy and skip the rest of the Audio conversion setup. Other wise, select Audio -> Full Processing Mode.
The first thing to decide is what quality audio you want. If you are concerned about quality, I suggest 160kbps (>160kbps bitrates are better quality, but the JBMM has audio sync problems with them). Otherwise, settings from 32kbps to 128kbps should suffice. If there is a lot of music in the clip, use higher bit rates. Lots of dialog? Lower bitrates are usually fine. If you have no idea, choose 128kbps.
Lets get the audio compression setup first:
Go to the Audio Menu
Select Full Processing Mode
Select Compression
Find LameMP3 in the list on the left.
If you can, check mark the Show all formats option.
Find the bit-rate you want. You will notice that there may be several lines with the same bit rate but other differences. Choosing stereo or mono is pretty straight forward. After you've chose stereo/mono and your bitrate, find the bitrate with the best sample rate (the biggest number on the left). Below you can see that I've selected 128kbps bitrate, Stereo, at 48000kHz. This is a good all-around setting.
Now, whatever setting you chose, remember the Stereo/Mono option and the kHz. We'll need this info next. Now we need to convert the audio. Actually, this happens first, but it is best to decide what your destination is (the MP3 settings we just did) before you setup conversion.
Go to the Audio Menu
Select Conversion
You should now see the dialog box pictured below. The key things are: make sure you convert to the same Stereo/Mono and kHz that you selected when we setup the MP3 encoder. Also, always select to convert to 16bit.
If you want, you can check-mark the High Quality check box - it'll be slower but sound better. Click OK and we are done setting things up!
Finally! Convert Your AVI!
Go to the File Menu
Select Save As AVI
Select where you want to save the AVI (some place with lots of space) and Name it.
Click Okay and watch it go!
You can now open and convert many files without having to go through all the setup. The current Video and Audio settings will not be forgotten until you quit VirtualDub. So, when you startup VirtualDub the next time, you'll have to reset them back up.
