Hey there,
I use OFS (Open Fun Scripter) and Motion Tracking Funscript Generator:

MTFG: https://discuss.eroscripts.com/t/motion-tracking-funscript-generator-v0-3-x/28117
I typically use MTFG where possible to stub in the key points, and adjust the value of each point to reflect the intensity of the stroke based on the action in the scene.
For some actions I have to work frame by frame, but for my scripts I tend to get very nuanced and try to capture every detail possible; something which is very time consuming.
Random Tips:
-
For motion tracking handjobs, if the performer is wearing a ring on her dominant hand; I usually use that as the tracking point, as the motion tracker seems to have an easier time tracking that than the hand itself.
For titfucking, motion tracking one of the performer’s nipples can work well too. -
For actions such as the release of a suck during a blowjob, dick slapping a tongue or breasts I typically use a pattern like that seen below, in which the frame just before the release of a suck, or contact between the dick at the surface I place a point with an intensity of 10, followed by a drop to 8 or 9 after two frames (depending on the weight of the action on screen which is for the release of a suck during a blowjob) followed by a rise to 10 after 4 to 6 frames. This creates a nice “tap” effect which can feel really good
(See image below for a reference)
Best of luck with your scripting!
