Any way to fix a corrupt movie file? Quicktime

Hi, I have a movie file that was recorded on my iPhone and I can watch about 2 seconds of it before it says “This movie could not be played”
I decided to put it on my computer to see if I can watch it but I can’t open it with Media Player Classic, it gets the error “Failed to render the file”
Are there any apps out there that can fix a vid or at least allow me to partially view and save it? Thanks!!!
