If I have the following:

Initial_Clock=0.0
Final_Clock=1.0
Initial_Frame=0
Final_Frame=59

What happens to the clock if I change Initial_Frame to 10 and 
Final_Frame to 30? Will the clock be automatically adjusted to fit 
within those bounds?

Thanks.

Mike

Yep: Frame 10 (the initial one) will then have a clock value of 0.0, and 
frame 30 (the final one) will have a clock value of 1.0.

I'm going to make a wild guess here and try to mind read, so if I get this wrong
clipka has it right already.

If the idea is to keep the start and end clock at zero and one for the frames 0
and 59 while changing only the midway portion, you can use Subset_Start_Frame
and Subset_End_Frame as 10 to 30 and those will adjust to the correct clock
value for that particular segment within the whole 60 frames.

Also abbreviated to +sf10 and +ef30 on the command line.

Bob
