1 - do not make any changes to Final Cut Pro. If you are editing in 720/59.94 DVCPro HD, then leave FCP set up for 720p/59.94 DVCPro HD for example. If you make any changes at all to FCP from your HD editing preset, the downconvert will not work.
2 - Use the AJA Control Panel to downconvert your HD to SD.
3 - Make your edit.
We've laid off dozens of 720 and 1080 shows to DVCAM and regular old BetaSP using this method. The edit always works, sometimes you get the warning that you're laying off an NDF Timeline to a DF master, and we just click "Ok."
