This is great! Thanks for showing off these new features. I'm eager to dig in and learn more about them myself!
While PD18 also had UHD preview resolution, PD19 seems to be able to play longer before the Serious Frame Drop Detected message comes up. Unlike PD18, if you choose the let PD pre-render the timeline, PD19 does so in small chunks whenever it's otherwise idle so it doesn't get in the way of editing.
Unfortunately, the rendered video is quite a bit lower in quality. A lower bitrate helps speed up the playback, but also completely defeats the purpose of having UHD preview. Take a look at the UHD Preview Resolution details of the source clip and the rendered version:
I've placed full size sceenshots from a 4K monitor along with the media details of both the source clip and PD-rendered version in this OneDrive
folder. I strongly recommend
not using the UHD preview setting if your PC keeps getting the Serious Frame Drop message.
