AS with the many New version that Totem has released over the Years.
Any time there has been a change in Version Number, it was not possible to go backwards.
example..
1.0.xxx to 1.1.xxx - cant go back to 1.0.xxx
1.1.xxx to 1.2.xxx - cant go back to 1.1.xxx
And both side are fundamentally correct..
While the new version was in Beta, their were plenty of warning in bold red that you couldn't go backwards..
But once it became the New Official Version.
Warnings, no longer need be posted.
It is, the Official version.
There have been many threads and discussions regarding the Sizing of the Clips.
Totem experimented with different options.
Totem is now Producing Cards properly Sized to fit the Resolution of your screen, and that should be what you Download.
Cards to Fit on Your Screen that don't need on the fly sizing.
1080p cards will fit the minimum 1080p screen size
720p cards will fit the minimum 720p screen size
If your Screen is somewhere in between 720p and not fully 1080p,
or your PC performance is low to mid range,
then it is recommended that you use 720p size cards.
If your Screen is 1080p or larger, and your PC performance is high then you should use the 1080p cards.
Not all Cards are 1080p:
Totem is in the process of Converting all of the older 720p cards ( from mid 2010 and Newer ) to 1080p.
Sizing only is an Issue if you have a mix of 1080p and 720p cards.
Advanced Software controls to Upsize or Downsize clips have been requested, and hopefully, Totem will hear our request and we see it in a future release.
Interesting information:
As of Today: the Majority of users still have 720p based Screen sizes.
they out number 1080p screens 2.4 to 1.
So the Bulk of Totems users are probably still using 720p screens.
Totem has to provide a GUI and Cards to support all members equally as well, the best they can.
Stats:
