David,
I opened a window just to see what I am putting into MPEG file.
The fragment could be:
FOR j=0, 31 DO BEGIN
READ_PICT,filnm,image
MPEG_PUT, mpegID, IMAGE=image, FRAME=j
ENDFOR
Does it make a difference?
Thank you,
Leonid.

I don't know. It would make a difference if your image
was not exactly the size you declared in the MPEG_OPEN
command. I was looking for reasons why you couldn't
write the file. This was the only one that occurred
to me that I thought might be plausible. :-)
Cheers,
David

I'm guessing that what you meant to write was this:
MPEG_PUT, mpegID, WINDOW=!D.Window, FRAME=j
Otherwise, why open a window? :-)
Cheers,
David
