Once the software finishes saving the recovered items, visit the selected location and check the recovered items.
The Stellar Photo Recovery software works on "what you see is what you can recover". That means the files will be recovered in the same manner as you were able to see them in the preview window after the scanning is complete.
The photo recovery software allows you to preview the video files having size less than or equal to 15 MB.
Based on the level of corruption, some of the recovered media files fail to open. All such files led to corruption before they were lost. Generally, the videos captured with the cameras get corrupt and require repairing. You can repair all corrupt video with Stellar Repair for Video software.
