It seems that "view" info is not saved in .cxs file. After I save the session, and open it the next time, 'view list' says 'No named views'. Steve

Probably. Just read the provided information about command files and making movies (links in my previous reply) including links from those pages to example movie files and tutorials, and experiment with executing your file containing some combination of action commands and “wait” commands to delay when the action commands start.
Whenever I make a script it involves a lot of trial and error, (re)executing the script and adjusting it. Just try it rather than asking here about each detail in your movie.
I suspect you will really be using much larger frame numbers, as 4 frames will happen in the blink of an eye. The “making movies” page has a discussion of frame rate at the bottom. Elaine

Hi Elaine, It looks like 'perframe' command allows me to execute multiple commands
at the same time. Is it possible to run one command for 4 frames, and the other 4 commands sequentially at each frame?
============ command 1: view view_a 4 #### transit to view_a
in 4 frames/steps
command 2: transparency #1 50 target s #### on frame 1 command 3: color # 2 magenta target c #### on frame 2 command 4: display #1/A:10 #### on frame 3 command 5: transparency #3 20 target c #### on frame 4 ============ Steve

other things at the same time as the movement transitions. In a command file, if you put multiple commands on the same line separated by semicolons (and no “wait” command between), they start executing at the same time.

To divide into more positioning stages, you would have to save more
views at the intermediate positions. Each transition would still be pairwise between two views.
In Chimera we had “scenes” that included not only position but also
display styles and colors, and transitions between scenes, but they are not currently available in ChimeraX.
I hope this helps, Elaine

Thanks Elaine! This is exactly what I want.
# save current view settings view save my_view_name
# move to another position, zoom in or out, and color some residues etc
# get back to the original view in 20 frames along a STRAIGHT line view my_view_name 20 =============
In the 20 frames of transition time, I can not do anything now. Is it
possible to do something during the transition, like changing the surface transparency? Can we save the view matrix, devide the transition into many steps, and do something else ( not motion-related, but coloring-related, etc) at each step?

(“view save”) of the desired start and end positions, possibly also intermediate positions, and then use “view” with frames argument to gradually transition from one previously saved view to the another. Saved views and their names are included in saved sessions.

Dear ChimeraX team, Thanks for your fast and detailed responses to my questions!
If a spot is in the center of view, we can zoom into the spot
through a straight line. If it's not, it's really difficult to get there through a straight line.
I tried something like this in a "movie" script, but it's still not
straight.
========= move y -20 zoom 1.25 wait 2 move y -20 zoom 1.25 wait 2 move y -20 zoom 1.25 wait 2 ========= Is there a way to zoom into a spot that is not in the center of view
through a straight line.
