Insert a single shot on a master

[Baz Leffler]

I have a similar problem editing to HDCAM using a Blackmagic card. It puts black at the end and the duration of the black is relative to the length of the insert eg. the longer the insert the longer the black (it is not the same length but a fraction there of). It use to be fine 2 weeks ago and the only thing I have changed is the BMD drivers. The solution would be to enter an out edit point but the edit to tape won’t let me!

What would I do without the ‘UNDO’ button!!!!
