This Mocha thing is really good but for me it looks like requires mote time. For sure for a big film I would use it as it can do a really good job. (btw, did Adobe not kill Mocha since CS6?)
Storage place is not a big issue. When I am donewith the project, I will remove all the 300GB stuff anyway.
I also need an option to modify them just a little (sometimes it is 1-2 frames only). The other thing is, that I cannot give the client an unstabilized material (and they do want to see it before color correcting) and stabilizing just for them the master for me is not the best option.
I do not render timline just at the end when I am having a break. CS5.5 does not support my video card for Mercury acceleration. So again I check it in AE, if it looks good there (in quaerter resolution) it will look good in Premiere after rendering.
I realized that for me it is a better workflow, though I totally understand your suggestion.
I will try this multi project idea and let you know what happened.
Thanks
