Hi crew, need help to synchronize a background spherical image with the camera animation; in the link attached you may see a mc laren skidding while actually it is still. I tried to render first the background and import it as a movie but there are several problems (image scaling, tangled controls, slow process...), so here I am. would you please help me? thanks in advance

always problems with the attachments

Looks the problem is the camera move. Try this: add a target help  in the center of the car, select both target helper and the camera and group them.Now just rotate the target helper and you will spin the camera aroud the car. What you can do here too isuse the Modifier Point At for the camera point to the target helper.

The camera's hot point can be moved to the car's center and the camera pivots up-down-sideways on it.  I'm curious what the camera's movement was based on.  You may not want the ground in view if it persists.

Ignore my post if you are wanting to move your camera in and out rather than zoom in or out.

nor the target helper neither the point at modifier did solve the problem; strange background behaviour: I placed the car at axis origin and the skidding remains the same even with the point at function; maybe is related to the camera lens (50 mm) or to the spherical image (the well-known Dosch hdr City). curious to know if anyone had the same animation problem

Well I did a test here and worked fine. You need totake care with your camera move, it need to be paralel to the ground all the time. Try to put the camera in the position on the first frame, move the camera hotpoint to the center of the car (sparrowhawk plugin can do this easy and for free), now use the spin modifier to rotate the  camera.
