I'm still wondering how it happened in the first place, but now the shimmer is gone and I couldn't be more pleased.
Thanks Cap'n Kevin for the idea of uploading two short clips, one produced complete with shimmer and the other in native form. Thanks to both you and JT for the solution and to Hal for confirming it. And thanks to everyone else who tried to help!
Once I saw where you were going with this and I compared both your settings, I went on to try other custom settings and came up with one that gave me a very clear pup video at a fraction of the size.
