Any tips for getting slow camera movement in AI Videos? Firely seems to fail at this completely

All I want is for the camera to push forward very slowly, on a fixed dolly path. I've tried every prompt I can think of.  No matter what I prompt, the camera always flies rapidly through the scene, either flying forward into to a tight close up or shooting completely past characters I want to remain in the frame.

The  video generator seems to have no undeerstanding of words like "slowly" or "slightly" or "subtley". The camera movement is always frantic and wobbly. I think if they want to be a serious tool for real filmmakers, they need to train the video generator properly to allow for standard cinematic shots.

Anyone have any hacks for prompting slow and solid camera movement?
