maddy I am sure you are frustrated but may I gently say that we are all waiting for a much-discussed fix for this. There is a memory problem. It increases with each frame rendered until the render stops when out of memory. CL is working on it. Luckily, it is so bad, and so many people have reported it here that it cannot be ignored or delayed and the fix will arrive. One way to live with this in the meantime....always exit all the way out of Poser and relaunch right before you render. That may not be enough, however. Have you ever considered rendering to single images? That way, if it stops far along you can resume where you left off. This practice gives you many other advantages, also. The only issue is: you have to assemble your folder of final images into a vid with an external piece of software. I use QuicktimePro ($29.99) for Mac and Win. There are many others, some free. Happy fishing! ::::: Opera :::::
