Working with Graphics and the Luma Keyer.
So I’m getting a double dose of fun and though I’m an intermediate Avid user, our company is making the move to Final Cut…I finally figured out how to make the graphics work in Final Cut, but in order to not re-invent my wheel, I’m trying to make this work in Avid and thus, save me time.
I have graphics that were given to me. One that says graphics (alpha) and then the graphics themselves.
For instance I have a lower third graphic.
Initially I had:
V4: Text
V3: Graphics (Alpha)
V2: Graphics
V1: VideoI placed a Matte Key over V3 and then clicked on “Swap Sources”.
That seemed to work in Avid, but on my Reference monitor, the graphics seemed to “bounce”.
So, then I tried applying Luma Keys to both V3 & V2 and messing with the Soft, Gain, Luminance, etc. but could never get it quite right.
Any easier way to do this? I’ve been pulling my hair out. 🙁

The way ya did it the first time is how ya handle old school matte and fills. Can they not just give you a finished graphic with an aplpha channel in tact?
I can’t see the bouncing you mentioned so it’s hard to say.

“That seemed to work in Avid, but on my Reference monitor, the graphics seemed to “bounce”.”
Are these animations or stills? If animations, check field dominance on your import settings: if DV, set for even (lower) first.
Now, if these are animations and they were rendered progressive (non-interlaced) for interlaced video, that may be the source of the “jerkiness.”
Also, depending on whether the graphics have very fine lines in them can contribute to this effect: interlacing “flicker” happens when a line less than 1 TV line in height “bounces” between fields.
