OK here is the situation - I have an animated video which has some close ups on the face, the lip sync is out. In some cases the dialogue if it starts in the right place will be out of sync by the end of the line. One can stretch this in using pro-tools elastic time, - no problem - but getting it to actually feel right is another matter. So my question to you guys is this:
Does anyone have any tips on how to make the lips sync feel right?
For instance do you have any particular speech sounds that you try to sync first to get the right effect, or do you feel that starting the dialogue early by a couple of frames makes the lip sync feel better? Any tips or tricks would be greatly appreciated.
I think we have found the problem and come up with a solution and I thought I would share it with you guys as you have all been so helpful. I spent a day cutting and moving each word to get them in sync with the animation usually by about half a frame one way or another (using a mirror matching the P's abd B's and not time stretching at all ;)). I then took my results and findings to the animators and showed them the issues. To cut a long story short, the problem was to do with frame rate, the simple explanation was the animators were working at 50 frames, but the game engine plays back at 30. The animation curves for the face were alaising from the 50 to the 30 meaning they were 'missing/averaging' 2/5ths of the information. So the solution to this problem is they are going to re animate at 30 fps and that should solve the majority or the issues. This is a great relief for me as I do not envy anyone who has to try and match lip sync by hand. It is also great that it is not always the case of 'fix it in post' -
