how can i play videos taken when power saving mode was on? will they be able to play at all?

I have a samsung galaxy s3. I went to a concert and forgot that power saving mode was turned on. I videoed some during the concert, and when I went to view the videos later it keeps saying can't play video. Is there something I can do to be able to play/watch the videos that I took?
