I saw the animation from youtube that you are using as reference and your video.
Yours animation looks good to me.
Are you using Camera and/or Projector tools?
If yes, are you using Bezier (curve) or Linear keyframes?
I think you are using the first (bezier).
If you are using an other tool like Crop & Position for the movement, you only have linear keyframes and then you have to use a little trick. Take a look at Cinelerra-GG: Title animation
Thank you. i am using projector.keyframe type is smooth. Watched the video of Cinelerra-GG: Title animation already & especially the graph which helped me a lot. Anyways, i am missing something in basics.
Apart from this may i know when to use tangent, disjoint, bump . tested in some videos. However a documentation /a video on about the difference between these curve type will help me to improve.
Finally, what are the ways to create easing animations. for now testing with speed percentage plugin.
