Basically, you cant export to tape from after effects. You can render your project to a file then use premiere or any editing software to export to tape. However, if you have a really fast system, you can use AE’s RAM preview to export to tape (using also the firewire output of AE). Check if your system is up to it. Make a ram preview and see if its playing all the frames consistently. If it does, then you could export to tape. I wouldnt recommend it as a good practice though.
