See attached picture. Several issues.
1:The video is OK but as you see numbers along the axes are not included. How to fix that? Or how to remove all?
2: The grid is different along all three axes, why?
3: Documentation of VideoWriter writes about many properties of a videoclip, like FrameRate. Where in the code this can be used?
axis([-3 3 -2 2 0 3.5]);
axis equal
grid on
%rest of code not shown
testfilm=VideoWriter('eerstefilm.avi');
open(testfilm);
writeVideo(testfilm,film);
close(testfilm);

Normally, before you open the video.
As for your other questions, it all depends on what film is. I would guess that it may be the result of getframe but you haven't shown that bit.

In the Command screen? Somewhere in the code?
It's up to you. If the code you show is in a script, then in that script. E.g. if you wanted to set the frame rate you'd replace:
testfilm=VideoWriter('eerstefilm.avi');
open(testfilm);
by
testfilm=VideoWriter('eerstefilm.avi');
testfilm.FrameRate = 30; %must be before the call to open
open(testfilm);
