Does anyone know of software for OS X that can quickly split a 2 hour H.264 video file into two 1 hour files? iMovie estimates 2 hours just to import the file. I was hoping for something that could do it quicker.
You might also be able to do this using Quicktime X. Open the movie, then choose Edit -> Trim... Trim away the second part of the movie file and do a save as to get the first part in a separate file. Re-open the original file and trim away the first part, save as to get the second part in a separate file.
I've only been able to try it with a 5 minute long movie, which was quick enough, but I'm unsure of how quickly it'll work with a 2 hour movie.
Split MPEG-4 movies with ease and speed.
If an application takes longer than a few minutes, it is likely re-encoding your movie. You do not want this because it risks reducing the quality of your split movie files.
Please note I wrote Movie Splitter and am likely bias.
Completely free, completely awesome.
