Q: Modifying Alpha Channel in Motion 5
I have used chroma key successfully in many video projects in Motion 5, however I am now interested in modifying and in some cases, removing an alpha channel from an imported clip. I have read the Users Manual and learned about exporting the video using Apple ProRes 4444 and ensuring the menu dropdown choice option include color or color and alpha, however I believe my question comes before exporting.
I have purchased video clips for use in my projects with alpha channels removed and would like to explore using that kind of editing feature myself.
Am I just exercising wishful thinking here or is removing alpha channel data possible within the Motion 5 editor no matter where I export the video?
Thanks for any assistance for a novice-to-medium-level-skilled editor.
