Recover videos permanently deleted in Photos
I have accidentally (permanently) deleted some videos in my Photos app (which were migrated from iPhoto), and think that are still in my iPhoto library. I need help recovering these.
I'm using Yosemite, and currently have two libraries - Photos library (37GB) and iPhoto Library (114GB). The Photos library was 114GB before deletion. Also, the iPhoto library says "Migrated iPhoto library" under description . My iPhoto app does not open, and asks me to to download the new iPhoto from the App store, which is not available. Since the iPhoto library is still 114GB, I think it contains my videos. I've tried to open this iPhoto library in Photos, and it opens without the videos. Both the 37GB and 114 GB libraries open in Photos and do not show the videos.
How can I recover my deleted videos (in either app)?
Mac Pro, OS X Yosemite (10.10.4)
