I assume no genlock?

No genlock. The cameras are consumer quality and therefore do not have a genlock input. At 30fps there is a possibility of noticeable timing miss-match between left and right clips, particularly if there is some  medium to fast movement of the subject. The maximum miss-timing could be 16.6mS ( 1/60 th of a second ). the amount I will get will be a random number between 0 and 16.6mS. In this case the miss-timing was measured to be 5mS and the subject ( damselfly ) is not moving too much.

I wanted to see what the quality of the 3d moving image would be like with the original footage at 4K. I found that the software editor ( Movie Studio Platimun 13 ) would not allow me to process the merged clips at 4K. So I scaled down the left and right clips to be 1920x1080 pixels 30fps which the software would accept. The output merged left and right clip for 3d cross-view is 1920x1080 pixels.

I suspected no genlock, as I noticed stereo "anomalies" in the faster-moving elements. I had to ask, though.

I wonder if adding a motion blur in post would help that...

In the original ( before I finally edited it ) the damselfly went almost off screen due to the strong wind moving the branch it is on. I cropped this part out and then found the clip was too short, so I stretched the timeline on the clip to make it last longer. This has resulted on a jerky movement ( repeat frames etc ). I have redone edit it without removing the piece of clip and let the clip play at it normal speed ( 30 fps ).

If it was possible to see the miss-timing between left and right , I'm sure motion blur would help to make it less noticeable on fast moving action.
