I've learned recently that videos shared in messanger and then uploaded to my laptop lose clarity when playing on a large screen. But this is the only way I know to share someone else' video. Video sizes on blogger are limited too, so it's the best I can do. It's not clear when viewed on a large screen, but at least it shows she is capable of walking in a straight line with me anyway .... but it really need to work with someone else at the end of the lead too.
