I found that the resolution on this animation was to low. The line work on the arm showed hints of the green screen. I could eliminate that hint of green with a refine soft matte filter in After Effects but the lines themselves were also blurred.
I had to double the size of the scene in Callipeg to get back the crisp line work. I imported the low resolution MP4 and redrew the arms for each frame. The pig was also re-animated but he didn’t need to be redrawn each time. When the scene was finished and the blue screen mp4 was imported into After Effects, I found the pig was stiffer than he needed to be. I added some overlapping action by dragging the head and ears as the meat was swinging. I am now wondering if I should arch the entire pigs body as it swings but that might be overkill for such a short shot. I would need to abandon the animation I did in Callipeg and re-animate the pig in After Effects using a png image. I could poke pins in the pig body to bend it as it swings.
I tried rendering the entire film last night but it failed. I used all the settings that worked on past renders of the film but this time vertical lines appeared across the renders in the preview window. Several scenes also renders off center with half the image appearing black. Everything looks fine when I play the movie in the program but the render is a nightmare of glitches and ticks.
Like Thomas Edison, I might have to face thousands of failed attempts before getting a clean render of the whole project. I searched multiple forums for people who have experienced similar problems and there are many. The solution has to be out there, I just need to find it.
