I'm trying to select a photo from a video in photos on my mac. I have Ventura OS

Hi Margaret Zuanich,

If Export to Frame Pictures is grayed out when following Export a still photo from a video in Photos on Mac, check your video.

• It won't export if you are in edit. If you see a yellow Done button on the top right you are in edit and need to click this button first.
• Make sure you have the video selected and Photos is reading it properly. Locate the video in Albums > Media Type > Videos to and try from there.
• If you are using iCloud, make sure all activity has been resolved (uploading and downloading) by following Check the status of your library in Photos for macOS.

Hope this helps.

Take care.

Try the following:

As a test launch Photos with the Option key held down and create a new, test library.  Import a video and test to see if the same problem persists. Does it? This tells us if the problem is limited to your current library or is more wide spread. If the problem is not present close that test library, reopen your current library and try again.

Photos may not be able to process the video. Is it an older video, imported before macOS 10.15 Catalina? Some older video codecs are no longer supported on Ventura.

As a test, try to export the original of the video to your Desktop, so you can check this particular video in a different app, for example in QuickTime Player.

I tested Photos and Quicktime Player and neither will let you save a frame as an image file. However, the free app VLC can save frames as TIFF files.
