Hi, everyone. I just downloaded MP4 Tools 3.7.2 in order to split a 2 ½ hour mp4 file into chapters. It worked great using the time function (I specified 00:00:00 to 00:24:36). When it was done, I renamed the split file. However, I then tried it on the next portion (00:24:36 to 00:48:53), but it doesn’t work. The only file it generates is a log file. I'd like to register the app, but I want to make sure it does what I need first. Can some of you help? Thanks! David
