Having looked again at the video it could be an old (very stretched) chain on a new sprocket ? Combined with the sub-optimal chainline that will throw chain off like that.
My experience of fixed conversions is that, on the workstand, if everything else is right even a poor chainline won't throw the chain off the sprocket like that, so I think there may be something else to it as well as the chainline.
Chain is brand new
Sprocket however is far from new
