What changed? Software update? Settings? Destination drive or folder? Source footage or file type? Plug-ins used?
Try rendering a project that worked before. If that is successful, start digging into the changes in the projects that are having problems. If nothing works then see the first question. Something did.
Hi Rick thanks for the reply.
I re-started the machine and tried some things and it's working again but still slow to engage, ie 20 seconds from the time I hit render to when it starts. That's on a comp with no fx.
Do you have MP enabled. Taking a long time to start is typical of Render Multiple Frames Simultaneously especially if you have a codec in the pipeline that is not MP compatible.
that was it! I saw it was switched on and - well - I guess I must have swtched it on a while back. My screw up, thanks Rick.
