Hi Dave
and thanks for your fast reply
Multiprocessing is turned off and so is open GL now.
sorry but i did not mention that i,m useing CS5 and i do have 1 footage
imported into AE its on video copilots Evolution DVD and its format is .MOV the rest are .PNG files.
I was quite happerly rendering all afternoon yesterday adding more and rendering again to see the result.The last thing i added was just more text.
When i render now as an AVI file it takes just one second to render and only renders a split second.I am no longer getting the ERROR Message.
yours
Stephen White.
