Okay. . I got something. .
.
Its in the AVLayer. . . setInterpolationTypeAtKey method takes care of the interpolation. . . with that I can set keyframe interpolation to LINEAR, BEIZERE OR HOLD. . .
But now my problem is how I set to something that we get by grabbing handles. . I need it to start very slowly at first keyframe and near the second keyframe it should be like sudden boost in speed. .

THANKS for Response. .
.
I want to do the same by running script. My script can create keyframes but can not change the speed right now. . . I was asking how to do the same (you told using graph editor/ select keyframe hit f9[easy ease]/ keyframe assistant etc). . . I can do it that way. . No problems. ..
.

• 1.I write the script using Extend script toolkit.
• 2. Run the script.
• 3. Script will set key frames.
• 4. script will set speed in between.
• 5. I’ll give the script to my friends for thier use

.
Again I want to do it using script.
