Converted a VV3 project to Vegas7. Before the project filesize was about 300k, now the *.veg is bigger than 500MB!!! This doesn't make any sense. Could it be there is anything else stored besides meta data? Does it store some audio??? Checked preferences bt cannot find anything.
It's also possible that VV3 veg files were not tested, since 4 versions back. Could be a Sony problem. If your disk drives check out OK, and the veg file says 500MB from within file manager, you should report it to Sony to investigate.
I solved the problem by opening a blank file in V7 and copy&pasting all tracks + markers to it. Now it's below 200k and everything works fine.
BTW: I zipped the 500MB file and it's size was reduced to approx. 300k, so I suppose it must be some sort of rubbish data stored in it. Probably a compatibility bug between V3 and V7.
