[gmx-users] High quality movies, bmp frames and videomach=poor quality

I am using tachyon to get high quality still pictures by generating a  
.dat file, changing the render numbers and then typing this command in  
the window

"N:/myhome/VMD1.8.7/tachyon_WIN32.exe" -aasamples 12 plot01.dat  
-format -o plot01.tga

This gives great images but now I am stuck on generating movies as I  
don?t seem to have much choice when using the movie-maker and am  
clueless at scripting. I need a movie file in .mpg or .avi for  
submission to a journal (and not bigger than 10MB).

Whenever I choose tachyon as the renderer within the movie maker I get  
frames generated in .dat which I can?t do anything with and when I use  
tachyon internal the files are automatically written in .bmp. I can?t  
seem to get my frames in targa or any format other than .bmp.

Is there a script command which could give me high quality snapshots in .tga?

If I continue with my frames in .bmp and generate a movie in videomach  
the image quality is very poor (I do this via preview movie and select  
the highest quality (fast 400x400). TO avoid this I have been using  
convert in unix to stick frames together but this won't give me a mpg  
or avi file!

Can anyone give me some advice or a script line similar to the one  
above which would work on a whole trajectory rather than a single
