An interesting watch, no doubt. Clearly, a decent amount of work was put into this project.
If I had one nit: I think he needs a better mic.
You do voice acting? It comes with the territory to focus on the vocal work, doesn't it? Some of it had an "on/off" quality which might be an artifact of his production process since he uses the voice to work out his video of the lip synching. This is from his website...
Next comes the most laborious phase - lip synching of dialogue. I open the individual scene sound files and obtain durations of word bursts (pieces of words) from the sound waveform. These are somewhat like syllables, but are geared to what needs to be seen on an animated character’s lips. These durations are converted to frames by multiplying by 24. These frame counts are recorded along with lip positions on a timing sheet which includes the dialogue words broken up into bursts. The lip positions that I and Filmation before me employed are: mouth fully shut, mouth open a bit with teeth visible, mouth open more showing black inside the mouth, mouth open a lot, mouth starting to form the "oo" sound as in the word moon, and finally the mouth position fully forming the "oo" sound. These timing sheets are used to string the named scene frames together to be rendered at 24 frames per second via the QuickTime Pro application.
I point this out only to wonder at the amazing feat of what he has accomplished!
