Tim,
AE Keylights worked fantastic!
Since I have never used AE, I opened clip and applied Keylights. Then I tried to save/export file. Evidently, AE must be similar to Premiere that requires a new creation to set preferences, etc.
The clip I opened was 1920 x 1080, the export option only offered 320 X ?. Later, will see if import Pro project file is option.
Anyway, Can you recommend a good book on AE4 that covers basics plus effects?
