TAA Number of Frames to Settle?

I’m rendering some images for a game I’m working on using Sequencer’s render movie tool, and I’d like to know how many frames it takes for TAA to fully settle at cinematic quality(r.PostProcessAAQuality=6)? Or in other words, how many frames are required until TAA’s full effect takes place? Does the Frame Rate effect the number of frames required to settle? With this info I will know how many frames to render before I start any animations.

I really like to know about it.
In fact It is better for cinematic shots to have a value to settle down for a bit for each frame , for instance 5 sec’s and then the image to be captured and so on.

is there any option for this?
