MoviePlayer playing Animation Codec?

I have a quicktime file with an alpha channel (Animation Codec) in the same folder as the binary. The below code will play a quicktime but not one with an Animation Codec it seems. Would anyone have any thoughts? Here’s the vid.

Dim f As FolderItem
f = GetFolderItem("")
MoviePlayer1.Speaker = True
MoviePlayer1.HasStep = False
MoviePlayer1.Movie = f.OpenAsMovie

Might have solved my own question.

Apple deprecated all of the legacy QuickTime API in Mavericks.

Convert it to modern format using older QTKit plugin from me and the Modenizer class there.

Plugin can be found here:


For those interested, I re-encoded the video into ProRes 4444. Here’s how:

Now I just need to figure out how to play the video and show the transparency :wink:
