I've created simple motion title graphics and what I'm experiencing is dropped frames until the play head is past the graphic. Even in Preview half mode it drops frames. The current workaround I came up with is to export the looped region of the title graphic as a Cineform 4444 AVI with Alpha transparency. Replace the generated title graphic with the video and no more dropped frames. I tried using XAVC-I clips on the timeline with the same results of dropped frames. IS this because the timeline performs better with AMD based cards?
Is this a known issue or???
