Currently it is very difficult to basic camera animation and change their speed which seems very simple task, but i dont know what those Seconds between camera move do, very confusing. even after doing some edits, it mess up the camera position in a random manner which destroy whole animation work.
why not simply define duration as suggested and also the ability to make cuts just like video editing to speed up/slow down. The consistency of frame size as per duration should be there.
Now
