I need to distribute groups of horizontal strips of images into a frame dimension 720x480 in odd even order. The dimension of each strip is 720x8. Each group has a total of 60 strips. Each group are subdivided into numberous sets that correspond to a different image.

For example, Group one contains 60 strips total. There are 2 sets in this group. Each set is 30 strips. Set A when put together create an image of a square. Set B puts together a circle. I have to fit these sets of strips in the frame (720x480) in odd even order. So set A is total of 30 strips, occupying 15 odds spaces and 15 even spaces in the 720x480 frame. Set B also 30 strips taking up the remaining 15 odd 15 even spaces.

I just need to figure out a math formular or SCRIPT that gives me the spacing between these strips.

Another more complicated example, another group has 3 sets.

Set A has 15 strips (7.5 odds strips and 7.5 even strips; that is like seven 720x8 strips and one 360x8 strip for each odd and even, 360 = 0.5 of 720)

Set B has 37.5 strips (18.75 odd and 18.75 even, specifically, eighteen 720x8 strips and one 540x8 strip for each odd and even. 540 = 0.75 of 720)

Set C has 7.5 strips. (3.75 odd; 3.75 even, three 720x8 strips and one 540x8 strip for each odd and even)

All will fit into 720x480. Just need to distribute them in even/odd order.

What am i doing?

I am studying repetative movements in nature. I need to match different types of natural motions which vary in speed and analyze their relationship to frame per second in video which is constant. These are simple motions like water droplets, waves, eyeblinking, ecetera.  So i figure I use the technique of telecine, figuring out cadence and distribution of frames and video fields to match one cadence to another. This is a crude experiment and even though natural movements do not have any predictable cadence, I am attempting to at least draw attention to that in the video.

Thanks for the support,
