Tutorial

Installing Rhubarb Lip Sync

First things first, you will need to download the latest version of Rhubarb Lip Sync. You can find it here.

Once you have downloaded the latest version of Rhubarb, you should navigate to c:/program files & create a new folder. Rename the new folder rhubarb. Now open up the zip file containing the latest version of Rhubarb & drag the contents into the rhubarb folder you just created.

Now minimize or close all open windows & double click on my pc/my computer; or whatever it is called on your pc. Wait for the window to open up & then right click somewhere where there is empty space, then click on properties. On the next window that opens up, click on advanced system settings, then click on environment variables on the next window that pops up.

Now you need to locate & select path found under system variables. Once you have done that, click on the edit button. Another window will pop up. Click on the new button & type C:/Program Files/rhubarb/ into the new entry that you just created, then click on the ok button. That's all there is to setting up Rhubarb Lip Sync on Windows. Close all the windows & you are done.

Using Rhubarb Lip Sync

Assuming you have installed Rhubarb Lip Sync, it's now time to generate your first tsv lip sync file - but first, what is a tsv file? tsv stands for tab separated values. It consists of a timestamp (in seconds) followed by a mouth shape letter or an animation frame number. It will look a little something like this...

0.00	X
0.67	B
etc.	etc.

Anyway, moving on... create a new folder somewhere on your pc & name it "lip_sync" - it should be somewhere that's easy to access; in my case, I created it on the D drive @ d:\lip_sync\.

Next copy/paste in the audio file (should contain clear speech in English - other languages are possible, but the end results will probably not be as accurate) that you want to generate lip sync data for.

Next, you should create a new txt file & give it the same name as the audio file. Open it up & type up the content of the audio file in text format.

Quick note: this step is entirely optional, but it is recommended because it helps Rhubarb generate more accurate lip sync data.

Once you have done that, it's time to open up Rhubarb. Press ⌘+R to open up the Run dialog box.

Quick note #1: the tsv lip sync files can contain either the mouth shape letters or animation frame numbers, so feel free to edit the tsv files & use numbers instead if you want to go beyond basic lip sync animations - maybe your characters contain animations for a wide range of emotions, or you want the head to face a different direction than where the body is facing, etc.

Quick note #2: Rhubarb can generate lip sync data from both wav & ogg (vorbis) audio file formats.
