When repositioning green screen element Goes Soft!!
Compositing a green screened talking head. Done it many times before using DVMatte. The usual keying is no problem. This is the first time I am repositioning the talking head and as soon as I repostion, the talking head element goes a bit soft.
Shot on BetaSP, brought in by AJA IO LA at 8bit. Always have had a clean key, but I guess I had never tried to reposition the keying element.
Is this the nature of beast or am I missing something. I have been rendering it out and not relying on RT effects. Any thoughts.

If you re-position graphics or any video image in FCP, make SURE the VERTICAL setting for each KEY-FRAME (start, stop or hold) is always a EVEN INTEGER (Even Whole Number). Examples: 4, not 3 / -144, not -143.27 / 336, not 335.62 / 12 not 11.
The positioning settings/info (as well as many other settings) are found under the “Motion” tab in the Viewer.
Vertical position is the number in the RIGHT window in the area called “Center” (the horizontal position is displayed in the LEFT window).I sometimes forget to check this and I can end up with images that look fuzzy when in-position.
This info applies to re-positioning anything on the Timeline: moving video, freeze-frames, internally-generated titles, and imported graphics.
It can be quite detrimental to the quality of your final output to not double-check this every time you reposition and/or re-size an image.

Thank you Rob. That was exactly it. I can’t believe I have never come across this before. You saved me a lot of trial and error. don
