In El Capitan (OS X 10.11.1), Photos, Quicktime Player and iMovie are a GUI mess of missing/inconsistent capabilities and keyboard shortcuts for handling videos.
For example Quicktime Player and iMovie provide keyboard shortcuts for playing/pausing and single frame stepping though a video using the space bar and right/left arrows keys. But Photos does not. In Photos you have to use the pop-up controller that obscures at least some part of the video. Worse yet, in Photos the space bar shortcut doesn’t play/pause the video, it opens/closes it.
These video playback inconsistencies are simply annoying. Where the missing capabilities get to be a serious PITA is the Photos app’s inability to correct the orientation of videos. And Photos regularly imports photos and videos in the wrong orientation from our iPhones running iOS 9.1. This is not a issue with simple photos since they can be easily rotated within the Photos app. But correcting this orientation error for videos is a lot more involved.
Correcting the orientation of a video requires exporting the video, opening it in QuickTime Player, rotating it, then saving it. After importing the rotated video back into Photos it appears in chronological order at the end of the photos list (i.e. based on when it was edited) unless the date is adjusted back to when the original video was taken. Simple right? Now try that with a slo-mo video.
If the video is slo-mo the procedure is even less obvious. Because it really matters exactly HOW you export the slo-mo video from Photos and HOW you save the rotated video out of Quicktime Player. In Photos, you have to “Export the unmodified original…” to keep the slo-mo portion of the video adjustable. Simply exporting the video (the default if you drag the video into a Finder window) will freeze the portion of the video that is slo-mo and remove the ability to change it. Similarly in Quicktime Player, if you use the File menu to “Export” the video, it will be saved with whatever portion of the video that had been set for slo-mo frozen. In other words, you will lose the ability to change the part of the video that is slow motion. So if you want to retain the ability to adjust the slo-mo portion later, you have to simply Close the window of the rotated video and then give it a new name using that save dialog. This changes the portion of the video that is set for slo-mo but it remains adjustable.
