    Installs FilesFrog malware even if you decline all adware. P.

    Running W7-64, I had no trouble installing MP4Joiner and declined all the "free" malware. It seemed to install but when I gave it two MP4s to join, it loaded them but never started the joining process. I tried running it as Administrator - same thing. I then unloaded it and reinstalled it and tried again. Nothing. I tried with another set of MP4s and then a third. Nada. Zilch, so I uninstalled it. MP4Joiner did not appear to load any mystery programs and I deleted the folder and looked for anything else that appeared at the same time but it looks like they might have cleaned up some of the malware issues. Easy to install and remove. I had high hopes and there is nothing unusual about my system, so all I can say is MP4Joiner could be a helpful program for some but not for me.

    Tried to use this - repeatable crash when I added the first mp4 file.

    I don't know whether this is open source, I would rather say that this is open spam. results = unusable. sound track desynchronized, and playing result file under VLC produces multiple full screens windows. spam. Windows installer proposes lots of unwanted advertising (careful to uncheck anything).

    After trying VideoDub and My MP4Box GUI, both programs had the problem of a delay being introduced into H.264 MP4's I was trying to join. Was getting frustrated and decided to give this a try. It works GREAT. I've tested about a dozen MP4's it joined and they are exactly as the original pieces (but now one file). It appears to do a direct stream copy, as it can work through about 4 hours of video in about 5 minutes. Plus, the file size on a 4Gb join ends up within hundreds of bytes of the combination of the source video MP4's. I'm sold -- great job -- this is my preferred MP4 video joiner (and only one I could find that works without spending about 50). Fortunately I listened to the two positive reviews above lele and dookus. Yes, it gives you options to load other stuff but you just need to READ the install dialogs as they are presented (which are just a sentence or two) and choose to install or not install. When you get to the one that is accept or decline, if you don't want the adware then just say "Decline" and it will still install the MP4 Joiner. I wasn't sure if "Decline" still would install the MP4 Joiner, but it does. Sad this gets a bad rap from a few reviews -- best MP4 joiner I found. THANKS TO THE DEVELOPER!
