Have anyone found any solution?

Does the demo project has that issue?

[siam009]

I have implemented uiimage to movie according to documentation. Later I found that the issue occurs only for png image. I have got no issue like this with jpg image. And I think that's okay.

I had the same issue and after debugging, I have found that

At lines 120 and 121
AVVideoWidthKey: outputSize.width,
AVVideoHeightKey: outputSize.height
were receiving dimensions beyond the PixelBuffer capacity.

This problem was happening because when I resized all images to the same size and persisted them locally with .jpegData(), I forgot to set the scale to 1, so when i passed the images to MTTransitions, it loaded the images as @3x scale, making them enormous.
