I had a working LipSync solution, so i just reordered my mouth frames and set it all up with the tsv.But it doesn't look good, so i though i was missing something.
Changing the milliseconds did affect how it looked, so i thought it may be related.
I will investigate further this evening.
Rhubarb Lip Sync is kind of basic as it uses the Hanna-Barbera animation approach to talk animations. 7-8 animations to cover some basic mouth shapes & then 1 animation frame for idle, however...
Simon reworked it so that we don't have to use the ABAC values that Rhubarb generates. You can replace the letters with frame numbers instead, which means that you can include as many mouth shapes as you want. You don't technically have to use Rhubarb to generate the tsv files, they just need to written out in the same format.
If you wanted to spice things up then you could create the same 8 frames with different moods on the characters face(s) & use animation frame values instead of ABAC values. It would be one way to make it look a lot more dynamic without having to manually determine which mouth shapes you need to use for each word, though I suppose you could use another lip sync tool to generate time stamps & the phonetic alphabet to help you figure out the mouth shapes for each word.
