I just re-rendered a Video that I created a couple of months ago and it looks exactly the same to me, definitely not worse in my case.
I may be wrong but I think that you will only get the full data set in the video if the Track is recorded with MRA Navigation or the MRA App (I cant remember which I used to record this a few months ago.)
I do think there are some changes required however.
The moments are probably the most important bit and they are rendered way to small and disappear far to quickly in my opinion.
