[Chimera-users] play movie forward then backward - script command?

[Gesa Volkers]

Dear Chimera-Programmers,

I like to create a movie in chimera by using a txt script and have some 
questions.

I saw that it is possible to check the box "play forward then backward" 
in the movie recorder but it does not work when I check the box and then 
run my script to create the movie (maybe this is not suprising..). How 
can I include this command into my script commands?

Another question. If I use the supersampling command, is it right to use 
the command as follows:

movie record fformat png supersample 4

OR

movie record fformat png supersample 4x4

Somehow I cannot see a difference in quality if I use the supersample 
command like this or if I do not use it at all, so I assume that 
something is wrong. Also the mp4-file size is always the same.

And a third question: I liked to upgrade Chimera to the current version 
(I use 1.5 (build 31025) 2010-07-20). But after the upgrade all my old 
saved sessions did not work anymore. Is there a solution for this? 
Because that keeps me from upgrading..

Thank you in advance for your help! I use Chimera a lot and I am always 
surprised how helpful the tutorials are and how fast the programmers 
respond to the users.
