Hi Chris & David -
I can confirm what Chris has observed, using clips from Canon 5D MkIV.
Shadow files were generated at 1920x1080 & play back correctly in the main timeline. The original files are 4096x2160 @ 523Mbps.
In the Trim module, here, audio plays back normally but video runs in slo-mo. Probably related to Chris' statement that "it runs on after the trim time runs out."
I repeated the test using UHD clips from Sony RX10MkIII - 3840x2160 @ 60Mbps - & the trim module playback was just fine, even though the properties of both sets of shadow files were identical. H.264 MP4 1920x1080 @ 8Mbps.
Here, the same thing occurs in PDR15 but (as Chris stated) PDR14 play back in Trim is not affected. Further to that, in support of the idea that Trim is not utilising the shadow file, if the actual shadow file is imported all playback is normal.
