Imported iPhone 11 Videos Don't Upload To Lightroom At Full Screen Size

[kathy55555]

When I upload videos from my iPhone 11 ProMax to Lightroom, SOME videos upload to display/play at full screen on my Windows laptop; however, SOME videos upload to display/play small (almost 1/2 the size of other videos).

Any idea why and/or how to change settings in Lightroom to expand the small videos to full screen like photos and other videos?

Thanks.

Are you importing the videos directly from your camera roll into the Lightroom Mobile app?  This will import videos at their full resolution (assuming they were captured on the same device and your device still has the original videos on your device camera roll).  Then, Lightroom for Windows will download and play the original videos you imported.

Since you are seeing small videos, it sounds like you are importing smaller copies of your videos and not the true original videos.  Can you elaborate on where the videos come from?  Did you transfer them onto your device from iCloud, Dropbox, etc?
