I rendered my project after applying an effect called video stabilizer. The red line turns green and playbacks fine. I saved my project then went back into it and now the work area that I rendered is no longer saved, the red line is back as if it was never rendered. This only happens with the effect video stabilizer. If I use a different effect Autotone & vibrance, the rendered file can be re-opened and it actually has saved. What is going on, can anyone help?
