I test with a model Jesus Palque.skp which had the Introduction Scene in Perspective and 2 other scenes in Parallel Projection.
The egenration of the video was showing the error you got too, which is due to the transition between camera in Perspective and camera in Parallel Projection
I will fix the problem, but if all scenes are in Parallel Projection, you can generate the video.
Here is the video if you change the first Scene 'Introduction' to Parallel Projection.
It's because you transition between a camera in perspective (Introduction) and a camera in parallel projection.
There is no simple way to interpolate between both, eacept than to switch at a given time (beginning, end or middle).
Considering your animation, I think all views should be in parallel projection.

Version 1.2.6 - 02.09.2026
With the latest versions of SketchUp there is a bug with the stipple pattern for construction lines and as a result it is nearly impossible to differentiate major grid lines from minor grid lines. Since this bug has never been resolved (at least to my knowledge) by the SketchUp team, I have determined that simple work around would be to replace the construction lines in the grid (major grid lines only) with regular lines or edges. Now one can actually tell them apart.
This option can be toggled in the General tab of the Global Settings.
Personally I prefer the dashed construction lines for the major grid lines but in newer versions of SketchUp solid lines are probably the better option.
I will look into the bug, which seems to concern camera interpolation when in parallel projection.
I'll advise then.
Do you have a camera in Parallel Projection mode?
