Second time of writing, this forum doesn't like images does it.
So importing some cine transfers with unusual sizes and 20 fps occasionally, not always, gives very strange results in P24.
The image is squashed and the framerate exports at about half what it should do.
Pinnacle 19 is fine, no problems, and most of the time 24 is also fine. Here is an image from P19 which shows how it should look.

And this is what I sometimes get in P24

As you can see, the preview image is squashed. It also outputs at a much lower frame rate, approx half.
Any ideas?
