Moving Colors

I am making a musical video featuring a windmill onto which I wish to add various effects to continuously change the colors of the sails. I have created images of the sails and chromakeyed out the background and have them rotating in rhythm with the music. First of all I want to make the colors continuously change starting from the center and radiating outwards. Secondly I want the sails to change continuously change color as they rotate, sometimes all change together, other times each sail to progressively change through the whole spectrum as they make a revolution so that each sail will independently go through the same color changes at the same angle, as it rotates through one revolution. If you see what I mean.

Can this be done with Vegas 4, and if so how would I do it?

Thanks.

Yes. Painstakenly. Good luck in your tasking.

Outside of that - I would keyframe the changes over multiple video events. If you start now - it should be done for a Autumn release.

Ron, it's possible. Yes. Possible to do it with Vegas but you'll have to make some space in your agenda for sure. If you do it, please post your clip on Chienworks site so we can see it. Always eager to see projects like the one you're planning to do!

After the early comments about my request I said to myself I AM going to do this. I put on my biggest thinking cap and came up with an idea which my first experiments suggest may work. I originally made a cardboard cutout of one sail, and inked in black a realistic looking framework. I then put a twelve second length on Track 1 and made it rotate around its hub in four seconds. I then copied it three times to seperate tracks and staggered them each by one second. This gave me a four second segment with all four sails rotating together, ninety degrees apart. I trimmed it down to that four seconds, and rendered it to a new track. I had made the background green and this can be chromakeyed it out to be transparent later on. I now had the four sails rotating at one revolution in four sconds, (i.e. one sail would hit TDC each second). I could now extend this in the Timeline for as many seconds as I needed.
That is all done. Now for my next trick. I can now Chromakey out the sails leaving only the inked in framework showing. Then I thought about putting a color wheel on the track below and set about downloading one from the Internet but ran into a virus problem so that hasn't happened yet, but I did put another clip on that track to prove that it would become visible through the sails. Now when I do get the color wheel it will give me the effect of the sails contnuously changing color as they rotate. By using the Spiral plug in it will give me the effect of the colors moving out along the blades. I can vary this by varying the tightness of the spiral, and by making it rotate at different speeds in relation to the sails. I would render this to a new track and can then Chromakey out the green background to show whatever background I like to put on the track below. I can also include a lot more effects that I haven't even begun to think about yet. I will let you know how it works when I have sorted out the virus problem.
