I recorded 20+ videos with my smartphone and copied them to my laptop. Most of them were fine but about five of them were not playable, allegedly file type unsupported, file extension incorrect, or file corrupt. OpenShot also reported that they're not valid videos. Well, I didn't change a thing and they ought to share properties with the rest of videos. So I copied those five videos back to my cellphone, and they turned out fine. What could be the problem here?

BTW,it's the first four videos and the sixth one. I don't see other patterns (e.g video length, horizontal/vertical e.t.c). Not sure what's relevant.

  • What did you record them on. What are you playing them back on? Makes and models!
