[FFmpeg-user] ProRes (LT) Quicktimes: Good for Windows. Not so good for Mac.

[Jeremy Oddo]

Has anyone else run into this issue:

We generate some ProRes (LT) Quicktimes on a Windows box. We play the
QT and the player says that it's a ProRes (LT). That's good.

We play the SAME quicktime on a Mac and it DOES NOT claim to be an
(LT). The quicktime needs to be re-rendered in Final Cut to make it a
true ProRes (LT). That's not good.

Is this a known issue? Is there a work-a-round?
