camera orbit around an object, camera walkthrough

[digital_technologies]

Dear Vantage team
One of the most common camera movements in archviz films is the orbit around an object shots.
This can be used in aerial , birds eye view shot that you orbit around your building , or even in interior shots, like orbit around a sculptue in a museum or orbit around a group of people making an activity
Unfortunately camera transition in vantage is not good at all for orbit. when you orbit more than 60 degrees the camera zooms ins and then zooms out , causting the object of focus to get out of the center.
As a result orbiting looks very weird.
I tried a solution to create different cameras every 40 degrees, but then the movement of the camera is not flowing nice. it accelerates and slows down, breaking the nice effect of orbit around an object.
Can you please fix this somehow.
Another similar thing. Actually camera movement is the most important means with which you tell a story in Vantage.
walkthrough camera movement is very common in this story telling. but when you create one continuous transition from camera to camera that includes moving forward , rotating, tranlation. look around, then the camera movement does not turn as one flowing camera movement.
it slows in and out even with linear transitions. Can you please give us a possilbility that vantage creates a path from the different cameras that we create and it automatically create a continuous flowing follow path. then give us the possibility to speed ramp in an intuitive way.
These two camera movements will improve significally the quality of our films, make them more interesting, while still explanatory
thank you very much in advance

Indeed the UI we have only allows for some basic transitions. Until we implement something more advanced, you should be able to use your DCC host application (3dsMax?) to create camera paths.

When you say the camera zooms in and out when attempting a long arc, I guess you mean that it goes in a straight line between the endpoints, not an arc. So the midpoint of the transition would be closest to the object, this is expected. I'm not sure why you were getting varying speed when attempting shorter transitions - if you set the type to 'Linear' and the transitions have equal length, it should result in constant movement speed. Maybe it _feels_ like the speed changes because these are still straight lines and not arcs, so the perspective changes a bit. You'd need very short steps, maybe 10-15 degrees to make the path segments resemble something close to a circle.

Similarly when you say your walkthrough speed varies, this is probably because the segments have different length in space and/or time, resulting in changes in speed.
