Hello dear users VirtualDub,
This is my pierszy post so please bear with us.
I'm using SketchUp. I generated a series of shots of him at two times larger than the target size of the movie. Poskladalem to in VirtualDub.
Unfortunately, some nearly vertical and horizontal lines flashing. They disappear and reappear. Apparently there are some techniques to fix this.

Adobe Premiere is apparently such a function. Can VirtualDub can help me?
Important information. It does not cause flicker VirtualDub. Sketchup on some frames "forgets" about some of the lines.
Regards,

It looks like a lot of the problem is due to the video encoding squashing some of the lines, which may be difficult to address without settings in the video codec/encoder itself. However, there are some things you can try.
First, it looks like the lines are aliased. Check if there is an option in SketchUp (or whatever you are rendering the animation with) to enable antlialiasing on the line rendering. This will substantially improve the quality of the rendering output and reduce stress on the codec.
Second, you might try rendering at a larger size, such as 4x what you intend to target. You can then resample this down in VirtualDub or any modern video program. This is another way to get antialiasing and will also improve line quality.
Third, you can try applying a slight blur to the entire video. It's a heavy-handed way to attack the problem, but sometimes it helps in cases like this.
