Mocha issues

Well, since my last blog, i approached the mocha programme, and went through a few clips and made a new track for them. It was going all pretty nicely. The track followed my finger very well and i took the tracked clips into after effects and began animating. I made another rainbow clip once again, added colour to it and put key frames in in all the suitable places and it played back very well. However, something went very very wrong and it was unable to to render properly, meaning no video was made.
This was very very annoying and we spent a long time trying to figure out what went wrong and where the problem was. But nothing could be found.
Although, i did get a few screen shots of the process so that was alright and the whole purpose of this was to see how smooth mocha made things compared to the original process. I made a few animations after that, which was able to render and proved that using mocha did make a lot of difference and does smoothly follow my finger.

I really don't know what went wrong in this process, but i do think mocha and trapcode and tracking something is reliable and won't usually go wrong, however, i did look into other techniques that i could use and that i could use at home where i don't have the plug in, which uni has, like simple tracking in the effects panel in, that doesn't need any trapcode, which does seem to work just as well. I did create a few animations and made videos, however, something again has gone wrong, and i'm stupidly saving the videos as massive files causing them to take ours to upload to vimeo. This is a problem i will solve soon.
