[Chimera-users] Supersample

[hsosa at aecom.yu.edu]

  The problem with supersampling does seems to be computer related.  I 
could make a movie with supersampling in another computer.   The graphic 
card in the problematic computer (Running Windows XP) is an:

ATI Radeon HD 2600 Pro AGP
Driver version: 8.410.0.0

Are there known problems with this graphic card /driver? . Any solution ?

I noticed that in the computer that I could make the movie the image 
changed size as each frame was being recorded (as expected when using 
supersampling). However, this did not occur in the computer that  
produced the bad  movie.

The script I am using  to make the movie looks now like this:
reset p0
movie record supersample 3
#movie record
wait 25
reset p1 1
wait
reset p2 1
wait
reset p3 1
wait
reset p4 1
wait
reset p7 1
wait
reset p8 1
wait
reset p9 15
wait 25
wait
reset p10 1
wait
reset p11 1
wait
reset p12 1
wait
reset p13 1
wait
reset p14 1
wait
reset p15 1
wait
reset p16 1
wait
reset p17 15
wait 25
movie stop
movie encode output Test.avi mformat avi bitrate 10000
#reset p0

Another question. Do I need to put a wait command after each reset command ?
 

Thanks

Hernando
