You could use buffers:

\newdimen\cnt
\starttext

\startbuffer [greenbar]
  \blackrule[width=4cm, height=5mm, color=green]
\stopbuffer

\dorecurse{10}{%%
  \blackrule[width=\textwidth]
  \advance\cnt1cm \hskip\cnt
  \getbuffer[greenbar]\page}

\stoptext

Hello Kumar.
I make my PDF animations so that I first create a single multi-page PDF 
file whose separate pages are separate animation frames.

Then this auxiliary PDF file I put into another PDF file using \ fieldstack.
Here's how I prepare a separate animation file.


\def\setmyparameter#1#2{%
\global\def\myparameter{#2}#1%
}%

\def\processmyparameters[#1]#2%
  {\processcommalist[#1]{\setmyparameter{#2}}}

\startbuffer [greenbar]
  \blackrule[width=\myparameter, height=5mm, color=green]
\stopbuffer


\starttext

\processmyparameters[1cm,2cm,3.5cm,4.5cm,8cm,11cm]{
  \getbuffer[greenbar]\page}

\stoptext


Greetings

Thank you for this solution. I just tried this, and this works well
for me as well!

This is a lovely solution, and I'll put off learning LuaTeX for
now. Thanks! :-)
