Yes, that tends to be more reliable unless the number of frames is large
because IM does things in memory. In that case, you can certainly do the
following:
1. output a sequence of individual frames at relatively high-resolution
2. run a script to loop through the images and interpolate down to lower
resolution (i.e., convert -geometry) to a temporary file as miff, tiff or
yuv depending on what you using for encoding
3. combine to a single file and encode (e.g., convert -adjoin
*foo-tmp.miff my_movie.mpg if you are using the Berkeley encoder with the
IM delegate)
Using individual files gives you the flexibility of editting, if needed.
If you are running into memory problems with convert, consider using
-cache. IM uses $TMPDIR for scratch files and cache, which by default is
set to /tmp. If you don't have enough space to deal with a long sequence
and/or large images, convert may crash unexpectedly and leave scratch files
there (e.g., look for mag*).

Subject: Re: [opendx-users] What tool or software can help me to
generate moviefile from OpenDX animation?
Rob,
I've had good results using OpenDX to create a single MIFF file instead of
separate image files. You still have to use ImageMagick to convert the MIFF
file to something else but that also worked well though it took hours.
