[x264-devel] out-of-range motion vectors

[List, Peter]

Ok, great...

So, do you think the drift to enormous motion values is not an issue? 
When I read what Cor observed:

I reason there still might be some suboptimality in the algorithm (not a criticism). Probably just a little tweak would be enough...
