As I have mentioned before I'm working on a project to record PhD seminars on in my departments. I have met with senior IT and recived a lot of feedback. Tonight the max file size will increase from 500MB to 2TB in the universities video hosting services. For some reason when recording longer videos the video camera seems to split the video files. I wonder if it is possible to merge two video files together with handbrake or if I need to use a second piece of software. I have read on a few sites that it can be done... but not sure if it is possible with .mp4 If this isn't possible,what software is recommended for merging .mp4 files?
