Photo Booth's stored pictures are loaded into your PC memory once you launch this app. You can clear stored pictures to help your machine with limited RAM. Too many stored pictures and videos may directly explain your lagging videos. And the less memory, the quicker the Photo Booth runs. You better do like this:

Step 1. Go to the user's home directory and find the Pictures folder (/user/Pictures/).

Step 2. Create a new folder in the Pictures directory and name it (You'd better name it like Photo Booth pictures/backups).

Step 3. Find the "Photo Booth" folder where Photo Boothe pictures and videos are stored.

Step 4. Now, you need to move all photo and video files from the "Photo Booth" to the newly created folder. You can do it manually or through Finder GUI or the command line:

mv "/user/Pictures/Photo Booth/*" "/user/Pictures/Photo Booth backups/"

Step 5. Now, ensure you have successfully moved all files into the new folder. If you do, relaunch the Photo Booth and reopen the lagging video to see if the problem persists.
