Hi -- this isn't really specifically an Adobe Premiere Pro issue, but that is the package I am using. It is really more of a workflow question, I think, or a conceptual approach.
I am rendering a multi-layered file of about 60 MovieStorm movies, using greenscreening to create a large, individually unique crowd. I usually do not have any issues exporting this. If I export it with all my Moviestorm puppets being largely still, there are no problems, but when I individually animated each one, and there is LOTS of motion in the export, you can see entire blocks being jerky in the final render -- for example, you might see an entire square of about about 20 soldiers jerking back and forth (the source there is one moviestorm movie, the entire track jerks back and forth in the final render).
Here's what I'm seeing. For best reaults, please download the file if you can, instead of viewing it in the dropbox previewer.
I have tried the following things in my export settings to address the issue:
- Turned on smooth frame blending
- Decreased keyframe from 72 to 10
- Made sure all my native exports from MS were the same frame rate (24fps -- I also tried them all at 30, and given the number of exports, that rendering takes literally days)
- made sure export fps matched input fps
- Owing to the decrease in keyframes, I increased the variable bit to 51 target, 60 max
- turned on macroblock adaptive frame-field coding
- output profile set to highest (5.1), maximum depth render
The inputs are all 1080p, as is the output -- rendered using 2-pass VBR (though I've also tried constant bit rates. I've read that decreasing keyframes helps remove jerkiness in high-motion renders, but that a large increase in the bit rate is required to take advantage. i don't fully understand why, so I may not be doing this portion correctly, but can't find information to the contrary).
Can anyone give any hints based on what you're seeing in the example file in my link?
