MP4Tools is a collection of cross-platform free tools to manipulate MP4 files.
It contains following applications:
⦁ MP4Joiner is a free application that allows join multiple MP4 files into one
⦁ MP4Splitter is a free application that allows split a MP4 file in multiple files
If you want a download that doesn't have the malware/adware wrapper, copy the link Sourceforge is trying to send you to, but then replace the "?source=files" string at the end of the URL with "?nowrap". You don't need to build it from source if you don't want to. MP4Joiner works exactly as advertised and joined two files that Quicktime wanted to spend 15 minutes re-encoding in about 90 seconds.
People seem a little confused, so I'll clear it up. It's the sourceforge installer that asks to change your homepage and all that. MP4 joiner itself doesn't do that after you get to it. Just pay attention to prompts, that's good advice for downloading /anything/ online because they all try to do that anymore. With that out of the way, the program does just as it says, more more no less. On those grounds it's pretty great. It did just, stop working on me and I had to reinstall. Don't know why.
I can confirm what others have written. No matter how great this software may be, despite not accepting any offers the vosteran malware was installed and hijacked my browser homepage and search preferences.
There is malware in this software package, even after declining everything I found that it hijacked my browser homepages and search bars. Avoid this software, and SF should consider taking it down.
The program works for joining files encoded with the same exact source i.e... OBS files will join with other OBS files using the same settings. However, if you encode one video in another program, lets say an intro to your OBS game video, even if they are encoded with the exact same settings the videos will not play right, and can even hang up your system once they are created. Once videos are in the list you cannot reorder them unless you remove them. You basically have to drag each video in one at a time in the order it's supposed to go. I won't even touch on the installer since everyone else beat me to it.
