It looks like your video didn't come through, you may have to post a link to it, I don't believe get satisfaction supports uploading videos. I tried flipping a few objects and they appear to be working, so I'm interested to see what's different.
Thanks for the video. Sorry about the confusion, the flip horizontal/vertical is only meant for objects that you've added to a capture and doesn't work on the capture itself. We can add that as a feature request though.
