i have an i5 with 16GB RAM and a GTX 660 Video card. i go to export my 1080p movie and i need it in WMV format, and with an hour long movie it takes it 12 hours. Am i doing something wrong that makes it take so long? or is this normal?
Have you used any third party plugins, if yes then try disabling the plugin before exporting.
Also try exporting in a different format (eg .MOV) & check if there is any variation in the time required for export.
Try with a different footage.
try exporting through Adobe Media Encoder.
